EXPLANATION
The Code of Federal Regulations is a codification of the general and
permanent rules published in the Federal Register by the Executive
departments and agencies of the Federal Government. The Code is divided
into 50 titles which represent broad areas subject to Federal
regulation. Each title is divided into chapters which usually bear the
name of the issuing agency. Each chapter is further subdivided into
parts covering specific regulatory areas.
Each volume of the Code is revised at least once each calendar year
and issued on a quarterly basis approximately as follows:
Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1
The appropriate revision date is printed on the cover of each
volume.
LEGAL STATUS
The contents of the Federal Register are required to be judicially
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie
evidence of the text of the original documents (44 U.S.C. 1510).
HOW TO USE THE CODE OF FEDERAL REGULATIONS
The Code of Federal Regulations is kept up to date by the individual
issues of the Federal Register. These two publications must be used
together to determine the latest version of any given rule.
To determine whether a Code volume has been amended since its
revision date (in this case, July 1, 2007), consult the ``List of CFR
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative
List of Parts Affected,'' which appears in the Reader Aids section of
the daily Federal Register. These two lists will identify the Federal
Register page number of the latest amendment of any given rule.
EFFECTIVE AND EXPIRATION DATES
Each volume of the Code contains amendments published in the Federal
Register since the last revision of that volume of the Code. Source
citations for the regulations are referred to by volume number and page
number of the Federal Register and date of publication. Publication
dates and effective dates are usually not the same and care must be
exercised by the user in determining the actual effective date. In
instances where the effective date is beyond the cut-off date for the
Code a note has been inserted to reflect the future effective date. In
those instances where a regulation published in the Federal Register
states a date certain for expiration, an appropriate note will be
inserted following the text.
OMB CONTROL NUMBERS
The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires
Federal agencies to display an OMB control number with their information
collection request.
[[Page vi]]
Many agencies have begun publishing numerous OMB control numbers as
amendments to existing regulations in the CFR. These OMB numbers are
placed as close as possible to the applicable recordkeeping or reporting
requirements.
OBSOLETE PROVISIONS
Provisions that become obsolete before the revision date stated on
the cover of each volume are not carried. Code users may find the text
of provisions in effect on a given date in the past by using the
appropriate numerical list of sections affected. For the period before
January 1, 2001, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, 1973-1985, or 1986-2000, published in 11 separate
volumes. For the period beginning January 1, 2001, a ``List of CFR
Sections Affected'' is published at the end of each CFR volume.
CFR INDEXES AND TABULAR GUIDES
A subject index to the Code of Federal Regulations is contained in a
separate volume, revised annually as of January 1, entitled CFR Index
and Finding Aids. This volume contains the Parallel Table of Statutory
Authorities and Agency Rules (Table I). A list of CFR titles, chapters,
and parts and an alphabetical list of agencies publishing in the CFR are
also included in this volume.
An index to the text of ``Title 3--The President'' is carried within
that volume.
The Federal Register Index is issued monthly in cumulative form.
This index is based on a consolidation of the ``Contents'' entries in
the daily Federal Register.
A List of CFR Sections Affected (LSA) is published monthly, keyed to
the revision dates of the 50 CFR titles.
REPUBLICATION OF MATERIAL
There are no restrictions on the republication of textual material
appearing in the Code of Federal Regulations.

Source: 36 FR 20751, Oct. 29, 1971, unless otherwise noted.
Subpart A_General
Sec. 1902.1 Purpose and scope.
(a) This part applies the provisions of section 18 of the Williams-
Steiger Occupational Safety and Health Act of 1970 (hereinafter referred
to as the Act) relating to State plans for the development and
enforcement of State occupational safety and health standards. The
provisions of the part set forth the procedures by which the Assistant
Secretary for Occupational Safety and Health (hereinafter referred to as
the Assistant Secretary) under a delegation of authority from the
Secretary of Labor (Secretary's Order No. 12-71, 36 FR 8754, May 12,
1971) will approve or reject State plans submitted to the Secretary. In
the Act, Congress declared it to be its purpose and policy ``* * * to
assure so far as possible every working man and woman in the Nation
[[Page 8]]
safe and healthful working conditions and to preserve our human
resources'' by, among other actions and programs, ``* * * encouraging
the State to assume the fullest responsibility for the administration
and enforcement of their occupational safety and health laws. Section
18(a) of the Act is read as preventing any State agency or court from
asserting jurisdiction under State law over any occupational safety or
health issue with respect to which a Federal standard has been issued
under section 6 of the Act. However, section 18(b) provides that any
State that desires to assume responsibility for the development and
enforcement therein of occupational safety and health standards relating
to issues covered by corresponding standards promulgated under section 6
of the Act shall submit a plan for doing so to the Assistant Secretary.
(b) Section 18(c) of the Act sets out certain criteria that a plan
which is submitted under section 18(b) of the Act must meet, either
initially or upon modification, if it is to be approved. Foremost among
these criteria is the requirement that the plan must provide for the
development of State standards and the enforcement of such standards
which are or will be at least as effective in providing safe and
healthful employment and places of employment as the standards
promulgated under section 6 of the Act which relate to the same issues.
(c)(1) If the Assistant Secretary approves a State plan submitted
under section 18(b), he may, but is not required to, exercise his
enforcement authority with respect to Federal standards corresponding to
standards approved under the plan until he determines, in accordance
with section 18(e) of the Act, on the basis of actual operations under
the plan, that the State is applying the criteria of section 18(c) of
the Act. The Assistant Secretary shall not make this determination (i)
for at least 3 years after initial approval of the plan, and (ii) in the
case of a developmental plan approved under Sec. 1902.2(b), until the
State has completed all the steps specified in its plan which are
designed to make it at least as effective as the Federal program and the
Assistant Secretary has had at least 1 year in which to evaluate the
program on the basis of actual operations. After the determination that
the State is applying the criteria of section 18(c) of the Act, the
Assistant Secretary's enforcement authority shall not apply with respect
to any occupational safety or health issue covered by the plan.
Notwithstanding plan approval and a determination under section 18(e)
that the section 18(c) criteria are being followed, the Assistant
Secretary shall make a continuing evaluation, as provided in section
18(f) of the Act, of the manner in which the State is carrying out the
plan.
(2) Federal enforcement authority which must be retained by the
Assistant Secretary until actual operations prove the State plan to be
at least as effective as the Federal program, will be exercised to the
degree necessary to assure occupational safety and health. Factors to be
considered in determining the level of Federal effort during this period
include:
(i) Whether the plan is developmental (i.e., approved under Sec.
1902.2(b)) or complete (i.e., approved under Sec. 1902.2 (a)).
(ii) Results of evaluations conducted by the Assistant Secretary.
(3) Whenever the Assistant Secretary determines, after giving notice
and affording the State an opportunity for a hearing, that in the
administration of the State plan there is a failure to comply
substantially with any provision of the plan or any assurance contained
therein, he shall withdraw approval of such plan in whole or in part,
and upon notice the State shall cease operations under any disapproved
plan or part thereof, except that it will be permitted to retain
jurisdiction as to any case commenced before withdrawal of approval
whenever the issues involved do not relate to the reasons for the
withdrawal of the plan.
(4) A determination of approval of a State plan under section 18(e)
does not affect the authority and responsibility of the Assistant
Secretary to enforce Federal standards covering issues not included
under the State plan.
(d) The policy of the Act is to encourage the assumption by the
States of the fullest responsibility for the development and enforcement
of their own
[[Page 9]]
occupational safety and health standards. This assumption of
responsibility is considered to include State development and
enforcement of standards on as many occupational safety and health
issues as possible. To these ends, the Assistant Secretary intends to
cooperate with the States so that they can obtain approval of plans for
the development and enforcement of State standards which are or will be
at least as effective as the Federal standards and enforcement.
(e) After the Assistant Secretary has approved a plan, he may
approve one or more grants under section 23(g) of the Act to assist the
State in administering and enforcing its program for occupational safety
and health in accordance with appropriate instructions or procedures to
be promulgated by the Assistant Secretary.
[36 FR 20751, Oct. 29, 1971, as amended at 61 FR 9230, Mar. 7, 1996]
Sec. 1902.2 General policies.
(a) Policy. The Assistant Secretary will approve a State plan which
provides for an occupational safety and health program with respect to
covered issues that in his judgment meets or will meet the criteria set
forth in Sec. 1902.3. Included among these criteria is the requirement
that the State plan provide for the development and enforcement of
standards relating to issues covered by the plan which are or will be at
least as effective in providing safe and healthful employment and places
of employment as standards promulgated and enforced under section 6 of
the Act on the same issues. In determining whether a State plan
satisfies the requirement of effectiveness, the Assistant Secretary will
measure the plan against the indices of effectiveness set forth in Sec.
1902.4.
(b) Developmental plan. A State plan for an occupational safety and
health program may be approved although, upon submission it does not
fully meet the criteria set forth in Sec. 1902.3, if it includes
satisfactory assurances by the State that it will take the necessary
steps to bring the State program into conformity with these criteria
within the 3-year period immediately following the commencement of the
plan's operation. In such case, the State plan shall include the
specific actions it proposes to take and a time schedule for their
accomplishment not to exceed 3 years, at the end of which the State plan
will meet the criteria in Sec. 1902.3. A developmental plan shall
include the date or dates within which intermediate and final action
will be accomplished. If necessary program changes require legislative
action by a State, a copy of a bill or a draft of legislation that will
be or has been proposed for enactment shall be submitted, accompanied by
(1) a statement of the Governor's support of the legislation and (2) a
statement of legal opinion that the proposed legislation will meet the
requirements of the Act and this part in a manner consistent with the
State's constitution and laws. On the basis of the State's submission
the Assistant Secretary will approve the plan if he finds that there is
a reasonable expectation that the State plan will meet the criteria in
Sec. 1902.3 within the indicated 3-year period. In such case, the
Assistant Secretary shall not make a determination under section 18(e)
of the Act that a State is fully applying the criteria in Sec. 1902.3
until the State has completed all the developmental steps specified in
its plan which are designed to make it at least as effective as the
Federal program, and the Assistant Secretary has had at least 1 year to
evaluate the plan on the basis of actual operations. If at the end of 3
years from the date of commencement of the plan's development, the State
is found by the Assistant Secretary, after affording the State notice
and opportunity for a hearing, not to have substantially completed the
developmental steps of the plan, the Assistant Secretary shall withdraw
the approval of the plan.
(c) Scope of State plan. (1) A State plan may cover any occupational
safety and health issue with respect to which a Federal standard has
been promulgated under section 6 of the Act. An ``issue'' is considered
to be an industrial, occupational or hazard grouping which is at least
as comprehensive as a corresponding grouping contained in (i) one or
more sections in subpart B or R of part 1910 of this chapter, or (ii)
one or more of the remaining subparts of part 1910. However, for cause
shown
[[Page 10]]
the Assistant Secretary may approve a plan relating to other industrial,
occupational or hazard groupings if he determines that the plan is
administratively practicable and that such groupings would not conflict
with the purposes of the Act.
(2) Each State plan shall describe the occupational safety and
health issue or issues and the State standard or standards applicable to
each such issue or issues over which it desires to assume enforcement
responsibility in terms of the corresponding Federal industrial,
occupational or hazard groupings and set forth the reasons, supported
with appropriate data, for any variations the State proposes from the
coverage of Federal standards.
(3) The State plan shall apply to all employers and employees within
the affected industry, occupational or hazard grouping unless the
Assistant Secretary finds that the State has shown good cause why any
group or groups of employers or employees should be excluded. Any
employers or employees so excluded shall be covered by applicable
Federal standards and enforcement provisions in the Act.
Subpart B_Criteria for State Plans
Sec. 1902.3 Specific criteria.
(a) General. A State plan must meet the specific criteria set forth
in this section.
(b) Designation of State agency. (1) The State plan shall designate
a State agency or agencies as the agency or agencies responsible for
administering the plan throughout the State.
(2) The plan shall also describe the authority and responsibilities
vested in such agency or agencies. The plan shall contain assurances
that any other responsibilities of the designated agency shall not
detract significantly from the resources and priorities assigned to
administration of the plan.
(3) A State agency or agencies must be designated with overall
responsibility for administering the plan throughout the State. However,
political subdivisions of the State may have the responsibility and
authority for the development and enforcement of standards, provided
that the State agency or agencies are given adequate authority by
statute, regulation, or agreement, to insure that the commitments of the
State under the plan will be fulfilled.
(c) Standards. (1) The State plan shall include or provide for the
development or adoption of, and contain assurances that the State will
continue to develop or adopt, standards which are or will be at least as
effective as those promulgated under section 6 of the Act. Indices of
the effectiveness of standards and procedures for the development or
adoption of standards against which the Assistant Secretary will measure
the State plan in determining whether it is approvable are set forth in
Sec. 1902.4(b).
(2) The State plan shall not include standards for products
distributed or used in interstate commerce which are different from
Federal standards for such products unless such standards are required
by compelling local conditions and do not unduly burden interstate
commerce. This provision, reflecting section 18(c)(2) of the Act, is
interpreted as not being applicable to customized products or parts not
normally available on the open market, or to the optional parts or
additions to products which are ordinarily available with such optional
parts or additions.
(d) Enforcement. (1) The State plan shall provide a program for the
enforcement of the State standards which is, or will be, at least as
effective as that provided in the Act, and provide assurances that the
State's enforcement program will continue to be at least as effective as
the Federal program. Indices of the effectiveness of a State's
enforcement plan against which the Assistant Secretary will measure the
State plan in determining whether it is approvable are set forth in
Sec. 1902.4(c).
(2) The State plan shall require employers to comply with all
applicable State occupational safety and health standards covered by the
plan and all applicable rules issued thereunder, and employees to comply
with all standards, rules, and orders applicable to their conduct.
(e) Right of entry and inspection. The State plan shall contain
adequate assurance that inspectors will have a right to enter and
inspect covered workplaces which is, or will be, at least
[[Page 11]]
as effective as that provided in section 8 of the Act. Where such entry
or inspection is refused, the State agency or agencies shall have the
authority, through appropriate legal process, to compel such entry and
inspection.
(f) Prohibition against advance notice. The State plan shall contain
a prohibition against advance notice of inspections. Any exceptions must
be expressly authorized by the head of the designated agency or agencies
or his representative and such exceptions may be no broader than those
authorized under the Act and the rules published in part 1903 of this
chapter relating to advance notice.
(g) Legal authority. The State plan shall contain satisfactory
assurances that the designated agency or agencies have, or will have,
the legal authority necessary for the enforcement of its standards.
(h) Personnel. The State plan shall provide assurance that the
designated agency or agencies have, or will have, a sufficient number of
adequately trained and qualified personnel necessary for the enforcement
of the standards. For this purpose qualified personnel means persons
employed on a merit basis, including all persons engaged in the
development of standards and the administration of the State plan.
Conformity with the Standards for a Merit System of Personnel
Administration, 45 CFR part 70, issued by the Secretary of Labor,
including any amendments thereto, and any standards prescribed by the
U.S. Civil Service Commission pursuant to section 208 of the
Intergovernmental Personnel Act of 1970 (Pub. L. 91-648; 84 Stat. 1915)
modifying or superseding such standards, will be deemed to meet this
requirement.
(i) Resources. The State plan shall contain satisfactory assurances
through the use of budget, organizational description, and any other
appropriate means that the State will devote adequate funds to the
administration and enforcement of the program. The Assistant Secretary
will make periodic evaluations of the adequacy of the State resources
devoted to the plan.
(j) State and local government employees. The State plan shall
include, to the extent permitted by State law, an effective and
comprehensive occupational safety and health program covering all
employees of public agencies of the State and its political
subdivisions. Such program shall be as effective as the programs
contained in the plan which are applicable to employees covered by the
plan.
(k) Employer records and reports. The State plan shall provide
assurances that employers covered by the plan will maintain records and
make reports to the Assistant Secretary in the same manner and to the
same extent as if the plan were not in effect.
(l) State agency reports to the Assistant Secretary. The State plan
shall provide assurances that the designated agency or agencies shall
make such reasonable reports to the Assistant Secretary in such form and
containing such information as he may from time to time require. The
agency or agencies shall establish specific goals, consistent with the
goals of the Act, including measures of performance, output and results
which will determine the efficiency and effectiveness of the State
program, and shall make periodic reports to the Assistant Secretary on
the extent to which the State, in implementation of its plan, has
attained these goals. Reports will also include data and information on
the implementation of the specific inspection and voluntary compliance
activities included within the State plan. Further, these reports shall
contain such statistical information pertaining to work-related deaths,
injuries, and illnesses in employments and places of employment covered
by the plan as the Assistant Secretary may from time to time require.

Sec. 1902.4 Indices of effectiveness.
(a) General. In order to satisfy the requirements of effectiveness
under Sec. 1902.3 (c)(1) and (d)(1), the State plan shall:
(1) Establish the same standards, procedures, criteria and rules as
have been established by the Assistant Secretary under the Act, or;
[[Page 12]]
(2) Establish alternative standards, procedures, criteria, and rules
which will be measured against each of the indices of effectiveness in
paragraphs (b) and (c) of this section to determine whether the
alternatives are at least as effective as the Federal program with
respect to the subject of each index. For each index the State must
demonstrate by the presentation of factual or other appropriate
information that its plan is or will be at least as effective as the
Federal program.
(b) Standards. (1) The indices for measurement of a State plan with
regard to standards follow in paragraph (b)(2) of this section. The
Assistant Secretary will determine whether the State plan satisfies the
requirements of effectiveness with regard to each index as provided in
paragraph (a) of this section.
(2) The Assistant Secretary will determine whether the State plan:
(i) Provides for State standards with respect to specific issues
which are or will be at least as effective as the standards promulgated
under section 6 of the Act relating to the same issues. In the case of
any State standards dealing with toxic materials or harmful physical
agents, they should adequately assure, to the extent feasible, that no
employee will suffer material impairment of health or functional
capacity even if such employee has regular exposure to the hazard dealt
with by such standard for the period of his working life, by such means
as, in the development and promulgation of standards, obtaining the best
available evidence through research, demonstrations, experiments, and
experience under this and other safety and health laws.
(ii) Provides an adequate method to assure that its standards will
continue to be at least as effective as Federal standards, including
Federal standards relating to issues covered by the plan, which become
effective subsequent to any approval of the plan.
(iii) Provides a procedure for the development and promulgation of
standards which allows for the consideration of pertinent factual
information and affords interested persons, including employees,
employers and the public, an opportunity to participate in such
processes, by such means as establishing procedures for consideration of
expert technical knowledge, and providing interested persons, including
employers, employees, recognized standards-producing organizations, and
the public an opportunity to submit information requesting the
development or promulgation of new standards or the modification or
revocation of existing standards and to participate in any hearings.
This index may also be satisfied by such means as the adoption of
Federal standards, in which case the procedures at the Federal level
before adoption of a standard under section 6 may be considered to meet
the conditions of this index.
(iv) Provides authority for the granting of variances from State
standards, upon application of an employer or employers which correspond
to variances authorized under the Act, and for consideration of the
views of interested parties, by such means as giving affected employees
notice of each application and an opportunity to request and participate
in hearings or other appropriate proceedings relating to applications
for variances.
(v) Provides for prompt and effective standards setting actions for
the protection of employees against new and unforseen hazards, by such
means as the authority to promulgate emergency temporary standards.
(vi) Provides that State standards contain appropriate provision for
the furnishing to employees of information regarding hazards in the
workplace, including information about suitable precautions, relevant
symptoms, and emergency treatment in case of exposure, by such means as
labeling, posting, and, where appropriate, medical examination at no
cost to employees, with the results of such examinations being furnished
only to appropriate State officials and, if the employee so requests, to
his physician.
(vii) Provides that State standards, where appropriate, contain
specific provision for the protection of employees from exposure to
hazards, by such means as containing appropriate provision for use of
suitable protective equipment and for control or technological
procedures with respect to such
[[Page 13]]
hazards, including monitoring or measuring such exposure.
(c) Enforcement. (1) The indices for measurement of a State plan
with regard to enforcement follow in paragraph (c)(2) of this section.
The Assistant Secretary will determine whether the State plan satisfies
the requirements of effectiveness with regard to each index as provided
in paragraph (a) of this section.
(2) The Assistant Secretary will determine whether the State plan:
(i) Provides for inspection of covered workplaces in the State,
including inspections in response to complaints, where there are
reasonable grounds to believe a hazard exists, in order to assure, so
far as possible, safe and healthful working conditions for covered
employees, by such means as providing for inspections under conditions
such as those provided in section 8 of the Act.
(ii) Provides an opportunity for employees and their
representatives, before, during, and after inspections, to bring
possible violations to the attention of the State agency with
enforcement responsibility in order to aid inspections, by such means as
affording a representative of the employer and a representative
authorized by employees an opportunity to accompany the State
representative during the physical inspection of the workplace, or where
there is no authorized representative, by providing for consultation by
the State representative with a reasonable number of employees.
(iii) Provides for the notification of employees, or their
representatives, when the State decides not to take compliance action as
a result of violations alleged by such employees or their
representatives and further provides for informal review of such
decisions, by such means as written notification of decisions not to
take compliance action and the reasons therefor, and procedures for
informal review of such decisions and written statements of the
disposition of such review.
(iv) Provides that employees be informed of their protections and
obligations under the Act, including the provisions of applicable
standards, by such means as the posting of notices or other appropriate
sources of information.
(v) Provides necessary and appropriate protection to an employee
against discharge or discrimination in terms and conditions of
employment because he has filed a complaint, testified, or otherwise
acted to exercise rights under the Act for himself or others, by such
means as providing for appropriate sanctions against the employer for
such actions and by providing for the withholding, upon request, of the
names of complainants from the employer.
(vi) Provides that employees have access to information on their
exposure to toxic materials or harmful physical agents and receive
prompt information when they have been or are being exposed to such
materials or agents in concentrations or at levels in excess of those
prescribed by the applicable safety and health standards, by such means
as the observation by employees of the monitoring or measuring of such
materials or agents, employee access to the records of such monitoring
or measuring, prompt notification by an employer to any employee who has
been or is being exposed to such agents or materials in excess of the
applicable standards, and information to such employee of corrective
action being taken.
(vii) Provides procedures for the prompt restraint or elimination of
any conditions or practices in covered places of employment which could
reasonably be expected to cause death or serious physical harm
immediately or before the imminence of such danger can be eliminated
through the enforcement procedures otherwise provided for in the plan,
by such means as immediately informing employees and employers of such
hazards, taking steps to obtain immediate abatement of the hazard by the
employer, and where appropriate, authority to initiate necessary legal
proceedings to require such abatement.
(viii) Provides adequate safeguards to protect trade secrets, by
such means as limiting access to such trade secrets to authorized State
officers or employees concerned with carrying out the plan and by
providing for the issuance of appropriate orders to protect the
confidentiality of trade secrets.
[[Page 14]]
(ix) Provides that the State agency (or agencies) will have the
necessary legal authority for the enforcement of standards, by such
means as provisions for appropriate compulsory process to obtain
necessary evidence or testimony in connection with inspection and
enforcement proceedings.
(x) Provides for prompt notice to employers and employees when an
alleged violation of standards has occurred, including the proposed
abatement requirements, by such means as the issuance of a written
citation to the employer and posting of the citation at or near the site
of the violation; further provides for advising the employer of any
proposed sanctions, by such means as a notice to the employer by
certified mail within a reasonable time of any proposed sanctions.
(xi) Provides effective sanctions against employers who violate
State standards and orders, such as those prescribed in the Act.
(xii) Provides for an employer to have the right of review of
violations alleged by the State, abatement periods, and proposed
penalties and for employees or their representatives to have an
opportunity to participate in review proceedings, by such means as
providing for administrative or judicial review, with an opportunity for
a full hearing on the issues.
(xiii) Provides that the State will undertake programs to encourage
voluntary compliance by employers and employees by such means as
conducting training and consultation with employers and employees.
(d) Additional indices. Upon his own motion or after consideration
of data, views and arguments received in any proceeding held under
subpart C of this part, the Assistant Secretary may prescribe additional
indices for any State plan which shall be in furtherance of the purpose
of this part, as expressed in Sec. 1902.1.
Sec. 1902.5 Intergovernmental Cooperation Act of 1968.
This part shall be construed in a manner consistent with the
Intergovernmental Cooperation Act of 1968 (42 U.S.C. 4201-4233), and any
regulations pursuant thereto.

conducted concerning the plan, the Assistant Secretary shall publish in
the Federal Register an appropriate notice concerning the plan and
provide an opportunity for formal hearing and decision on the possible
rejection of the plan and on any subsidiary issues. The notice also
shall set forth such rules as may be necessary so as to assure
compliance with 5 U.S.C. 556 and 557 in the conduct of the proceeding.
The time for filing proposed findings and conclusions and exceptions to
any tentative decision shall be set forth in the notice.

Subpart D_Procedures for Determinations Under Section 18(e) of the Act
Source: 40 FR 54782, Nov. 26, 1975, unless otherwise noted.
General
Sec. 1902.30 Purpose and scope.
This subpart contains procedures and criteria under which the
Assistant Secretary of Labor for Occupational Safety and Health
(hereinafter referred to as the Assistant Secretary) under a delegation
of authority from the Secretary of Labor (Secretary's Order 12-71, 36 FR
8754) will make his determination on whether to grant final approval to
State plans in accordance with the provisions of section 18(e) of the
Occupational Safety and Health Act of 1970 (29 U.S.C. 667) (hereinafter
referred to as the Act).
Sec. 1902.31 Definitions.
As used in this subpart, unless the context clearly indicates
otherwise:
Act means the Occupational Safety and Health Act of 1970 (29 U.S.C.
651 et seq.)
Affirmative 18(e) determination means an affirmative determination
under section 18(e) of the Act that the State plan or any modification
thereof, is in actual operation meeting the criteria
[[Page 18]]
and indices of section 18(c) of the Act and subpart B of this part so as
to warrant the withdrawal of the application of discretionary Federal
enforcement and standards authority from issues covered by the plan, or
by any modification thereof.
Assistant Regional Director means the Assistant Regional Director
for Occupational Safety and Health for the region in which a State is
located.
Assistant Secretary means the Assistant Secretary of Labor for
Occupational Safety and Health.
Commencement of a case under section 18(e) of the Act means, for the
purpose of retaining Federal jurisdiction despite an affirmative 18(e)
determination, the issuance of a citation, and in the case of an
imminent danger, the initiation of enforcement proceedings under section
13 of the Act.
Commencement of plan operations means the beginning of operations
under a plan following the approval of the plan by the Assistant
Secretary and in no case may be later than the effective date of the
initial funding grant provided under section 23(g) of the Act.
Development step includes, but is not limited to, those items listed
in the published developmental schedule, or any revisions thereof, for
each plan contained in 29 CFR part 1952. A developmental step also
includes those items specified in the plan as approved under section
18(c) of the Act for completion by the State, as well as those items
which under the approval decision were subject to evaluations. (See
e.g., approval of Colorado and Michigan plans, 38 FR 25172, 38 FR 27388,
respectively), and changes deemed necessary as a result thereof to make
the State program at least as effective as the Federal program within
the 3 years developmental period. (See 29 CFR 1953.4(a)).
Initial approval means approval of a State plan, or any modification
thereof, under section 18(c) of the Act and subpart C of this part.
Person means any individual, partnership, association, corporation,
business trust, legal representative, organized group of individuals, or
any agency, authority or instrumentality of the United States or of a
State.
Separable portion of a plan for purposes of an 18(e) determination
generally means more than one industrial, occupational or hazard
grouping as defined in Sec. 1902.2(c)(1) which is administratively
practicable and reasonably separable from the remainder of the plan.
(See 29 CFR 1952.6(a).)
[40 FR 54782, Nov. 26, 1975, as amended at 67 FR 60128, Sept. 25, 2002]
Sec. 1902.32 General policies.
(a) Sections 18 (e) and (f) of the Act provide for the continuing
evaluation and monitoring of State plans approved under section 18(c) of
the Act. The Assistant Secretary's decision whether to grant an
affirmative 18(e) determination will be based, in part, on the results
of these evaluations. Section 18(e) provides that a period of not less
than 3 years shall have passed before the Assistant Secretary may make a
determination that the State program in actual operations is applying
the criteria of section 18(c) of the Act. In the case of a developmental
plan, Sec. 1902.2(b) of this part requires that the Assistant Secretary
must have at least one year in which to evaluate the plan's actual
operations following the completion of all developmental steps specified
in the plan. Thus, to be considered for an 18(e) determination, at least
three years shall have passed following commencement of operations after
the initial approval of a State's occupational safety and health plan by
the Assistant Secretary. In the case of a developmental plan, at least
one year shall have passed following the completion of all developmental
steps, but, in any event, at least three years must have passed
following initial approval of the plan before discretionary Federal
enforcement authority and standards may be withdrawn from issues covered
by an approved plan.
(b) In making an 18(e) determination, the Assistant Secretary will
determine if actual operations under a State's plan, or under a
separable portion of the plan, indicate that the State is applying the
criteria of section 18(c) of the Act and the indices of effectiveness of
subpart B of this part in a manner which renders operations under the
plan ``at least as effective as'' operations under the Federal program
in
[[Page 19]]
providing safe and healthful employment and places of employment within
the State. In making this determination, the Assistant Secretary may
consider such information which he deems appropriate for an informed
decision.
(c) If the Assistant Secretary makes an affirmative 18(e)
determination, the Federal enforcement provisions of sections 5(a) (2),
8 (except for the purposes of continuing evaluations under section 18(f)
of the Act), 9, 10, 13 and 17 and standards promulgated under section 6
of the Act shall not apply with respect to those occupational safety and
health issues covered under the plan which have been given an
affirmative 18(e) determination. However, the Assistant Secretary may
retain jurisdiction over proceedings commenced under sections 9, 10 and
13 of the Act before the date of his determination. In addition, the
Assistant Secretary shall retain his jurisdiction under the anti-
discrimination provisions of section 11(c) of the Act.
(d) If the Assistant Secretary determines that a State plan, or any
portion thereof, has not met the criteria for an 18(e) determination, he
shall retain his authority under the enforcement provisions of sections
5(a) (2), 8, 9, 10, 13, and 17 and his standards authority under section
6 of the Act in the issues found ineligible for an 18(e) determination.
In addition, his decision may result in the commencement of proceedings
for withdrawal of approval of the plan, or any separable portion
thereof, under 29 CFR part 1955.
(e) Once a State's plan, or any modification thereof, has been given
an affirmative 18(e) determination, the State is required to maintain a
program which will meet the requirements of section 18 (c) and will
continue to be ``at least as effective as'' the Federal program
operations in the issues covered by the determination. As the Federal
program changes and thereby becomes more effective, the State is
correspondingly required to adjust its program at a level which would
provide a program for workplace safety and health which would be ``at
least as effective as'' the improvements in the Federal program. A
failure to comply with this requirement may result in the revocation of
the affirmative 18(e) determination and the resumption of Federal
enforcement and standards authority and/or in the commencement of
proceedings for the withdrawal of approval of the plan, or any portion
thereof, pursuant to 29 CFR part 1955.
(f) The Assistant Secretary may reconsider and, if necessary,
rescind or revoke all or a separable portion of an affirmative 18(e)
determination and reinstate concurrent Federal enforcement authority if
he finds that a State does not maintain its commitment to provide a
program for employee safety and health protection meeting the
requirements of section 18(c) of the Act. This authority is designed to
be used in instances where operations under a State program are found to
be less effective than under the Federal program because of unusual
circumstances which are temporary in nature. The Assistant Secretary may
also use this procedure to reinstate Federal enforcement authority in
conjunction with plan withdrawal proceedings in order to ensure that
there is no serious gap in his commitment to assure safe and healthful
working conditions so far as possible for every employee.
Completion of Developmental Steps--Certification
Sec. 1902.33 Developmental period.
Upon the commencement of plan operations after the initial approval
of a State's plan by the Assistant Secretary, a State has three years in
which to complete all of the developmental steps specified in the plan
as approved. Section 1953.4 of this chapter sets forth the procedures
for the submission and consideration of developmental changes by OSHA.
Generally, whenever a State completes a developmental step, it must
submit the resulting plan change as a supplement to its plan to OSHA for
approval. OSHA's approval of such changes is then published in the
Federal Register and the pertinent subparts of part 1952 of this chapter
are amended to reflect the completion of a developmental step.
[67 FR 60128, Sept. 25, 2002]
[[Page 20]]
Sec. 1902.34 Certification of completion of developmental steps.
(a) Upon the completion of all of the developmental steps in a
State's plan, which is to be accomplished not later than three years
following commencement of plan operations after approval of the plan by
the Assistant Secretary under section 18(c), the Assistant Regional
Director shall certify, as provided in paragraph (b) of this section,
that all developmental steps in the plan have been met and that the
State's program is to be evaluated on the basis of its eligibility for
an 18(e) determination after at least one year of evaluations of the
plan.
(b) Upon determining that a State has completed all of its
developmental steps, the Assistant Regional Director shall prepare a
certification which he shall promptly forward to the Assistant
Secretary. The certification shall include, but shall not be limited to,
the following;
(1) A list of all developmental steps or revisions thereof, plan
amendments or changes which result in the completion of the steps or
revisions thereof, and the dates the Assistant Secretary's or the
Assistant Regional Director's approval of each change was published in
the Federal Register;
(2) Substantive changes, if any, in the State program which were
approved by the Assistant Secretary and their dates of publication in
the Federal Register;
(3) Documentation that the legal basis for the applicable State
merit system has been approved by the U.S. Civil Service Commission and
that the actual operations of the State merit system has been found
acceptable by the Occupational Safety and Health Administration with the
advice of the U.S. Civil Service Commission; and
(4) A description of the issues which are covered by the State plan.
Where applicable, the certification shall include a description of those
separable portions of the plan which have been certified for 18(e)
evaluation purposes as well as those portions of the plan which were not
certified by the Assistant Regional Director.
(c) After a review of the certification and the State's plan, if the
Assistant Secretary finds that the State has completed all the
developmental steps specified in the plan, he shall publish the
certification in the Federal Register and amend the appropriate subpart
of part 1952 of this chapter to reflect this finding.
Sec. 1902.35 Effect of certification.
Publication of the certification acknowledging the completion of all
of the developmental steps in a State's plan will automatically initiate
the evaluation of a State's plan for the purposes of an 18(e)
determination. Evaluation for the purposes of an 18(e) determination
will continue for at least one year after the publication of the
certification in the Federal Register. Federal enforcement authority
under sections 5(a)(2), 8, 9, 10, 11(c), 13, and 17 of the Act and
Federal standards authority under section 6 of the Act will not be
relinquished during the evaluation period. Evaluation conducted for
18(e) determination purposes will be based on the criteria set forth in
Sec. Sec. 1902.37 and 1902.38.
Basis for 18(e) Determinations
Sec. 1902.36 General provisions.
(a) In making his evaluation of the actual operations of a State's
plan for the purposes of an 18(e) determination, the Assistant Secretary
shall consider all relevant data which will aid him in making an
effective determination. In his evaluation he shall consider whether the
requirements of section 18(c) of the Act and the criteria for State
plans outlined in subpart B of this part as well as those in Sec.
1902.37 are being applied in actual operations for a reasonable period
of time in a manner which warrants the termination of concurrent Federal
enforcement authority and standards in issues covered under the plan.
(b) The Assistant Secretary's evaluation for an 18(e) determination
will be addressed to consideration of whether the criteria and indices
in Sec. 1902.37(a) are being applied by the State in such a manner as
to render its program in operation at least as effective as operations
under the Federal program. In considering the question of such
application, the Assistant Secretary shall also consider the factors
provided
[[Page 21]]
under Sec. 1902.37(b). The Assistant Secretary's evaluation may include
such other information on the application of the criteria and indices in
Sec. 1902.37 such as information developed from comments received from
the public and the results of any hearings which may have been held
under Sec. 1902.40 concerning the proposed 18(e) determination.
Sec. 1902.37 Factors for determination.
(a) The Assistant Secretary shall determine if the State has applied
and implemented all the specific criteria and indices of effectiveness
of Sec. Sec. 1902.3 and 1902.4 of this part.
(b) In determining whether a State has applied the criteria and
indices of effectiveness in paragraph (a) of this section in actual
operations, the Assistant Secretary will, among other things related to
the application of the criteria and indices, consider whether:
(1) The State has a sufficient number of adequately trained and
competent personnel to discharge its responsibilities under the plan.
(2) The State has adhered to the procedures which it has adopted and
which have been approved either under the State plan or in State plan
changes or under any other procedures for approval authorized by the
Assistant Secretary.
(3) The State has timely adopted all Federal standards, and
amendments thereto, for issues covered under the plan or has timely
developed and promulgated standards which are at least as effective as
the comparable Federal standards and amendments thereto.
(4) If the State has adopted Federal standards, the State's
interpretation and application of such standards have been consistent
with the applicable Federal interpretation and application. Where the
State has developed and promulgated its own standards, such standards
have been interpreted and applied in a manner which is at least as
effective as the interpretation and application of comparable Federal
standards. This requirement acknowledges that State standards may have
been approved by the Assistant Regional Director, but emphasizes the
requirement that the standards are to be at least as effective as the
comparable Federal standards in actual operations.
(5) If any State standard, whether it is an adopted Federal standard
or a standard developed by a State, has been subject to administrative
or judicial challenge, the State has taken the necessary administrative,
judicial or legislative action to correct any deficiencies in its
program resulting from such challenge.
(6) In granting permanent variances from a standard the State has
assured that the employer provides conditions of employment which are as
safe and healthful as those which would prevail if he complied with the
standard.
(7) In granting temporary variances from a standard, the State has
ensured that the recipient of the variance has come into compliance with
the standard as early as possible.
(8) The State inspection program is being implemented in a manner
which allows a sufficient allocation of resources to be directed toward
target industries and target health hazards as designated by the State
while providing adequate attention to all other workplaces covered under
the plan, or any modification thereof.
(9) The State exercises the authority through appropriate means, to
enforce its right of entry and inspection wherever such right of entry
or inspection is refused.
(10) Inspections of workplaces are conducted by State inspectors in
a competent manner, following approved enforcement procedures. This
includes a requirement that the inspectors obtain adequate information
to support any citations which may be issued.
(11) The State issues citations, proposed penalties and notices for
failure to abate in a timely manner.
(12) The State proposes penalties in a manner at least as effective
as under the Federal program, including the proposing of penalties for
first instance violations and the consideration of factors comparable to
those required to be considered under the Federal program.
(13) The State ensures the abatement of hazards for which a citation
has been issued, including the issuance of notices of failure to abate
and appropriate penalties.
(14) Wherever appropriate, the State agency has sought
administrative and
[[Page 22]]
judicial review of adverse adjudications. This factor also addresses
whether the State has taken the appropriate and necessary
administrative, legislative or judicial action to correct any
deficiencies in its enforcement program resulting from an adverse
administrative or judicial determination.
(15) Insofar as it is available, analysis of the annual occupational
safety and health survey by the Bureau of Labor Statistics, as well as
of other available Federal and State measurements of program impact on
worker safety and health, which analysis also takes into consideration
various local factors, indicates that trends in worker safety and health
injury and illness rates under the State program compare favorably to
those under the Federal program.

Procedures for 18(e) Determination
Sec. 1902.38 Evaluation of plan following certification.
(a) Following the publication in the Federal Register under Sec.
1902.34 of the certification acknowledging the completion of all
developmental steps specified in the plan, or any portion thereof, the
Assistant Secretary will evaluate and monitor the actual operations
under the State plan for at least 1 year before determining whether the
State is eligible for an 18(e) determination. The evaluation will assess
the actual operation of the State's fully implemented program in
accordance with the criteria in Sec. 1902.37 and take into account any
information available to the Assistant Secretary affecting the State's
program.
(b) The Assistant Regional Director shall prepare a semi-annual
report of his evaluation of the actual operations under the State plan
or any portion thereof in narrative form. The Assistant Regional
Director's evaluation report will be transmitted to the Assistant
Secretary who will then transmit the report to the State. The State
shall be afforded an opportunity to respond to each evaluation report.
[40 FR 54782, Nov. 26, 1975, as amended at 42 FR 58746, Nov. 11, 1977]
Sec. 1902.39 Completion of evaluation.
(a) After evaluating the actual operations of the State plan, or any
portion thereof, for at least 1 year following publication of the
certification in the Federal Register under Sec. 1902.34, the Assistant
Secretary shall notify the State whenever he determines that the State
will be eligible for an 18(e) determination. In addition, a State may
request an 18(e) determination following the evaluation period noted
above. In no case shall this determination of eligibility be later than
2 years following the publication of the certification of the completion
of developmental steps in the Federal Register under Sec. 1902.34. In
the case of a plan which was not developmental, the determination of
eligibility shall not be sooner than 3 years following the date of
commencement of operations under the plan.
(b) After it has been determined that a State will be eligible for
an 18(e) determination, the Assistant Regional Director shall prepare a
final report of his evaluation of the actual operations under a State's
plan or portion thereof which may be subject to the 18(e) determination.
The Assistant Regional Director's report shall be transmitted to the
Assistant Secretary. The Assistant Secretary shall transmit such report
to the State and the State shall have an opportunity to respond to the
report.
(c) Whenever it has been determined that a State's plan, or
separable portion thereof, is eligible for an 18(e) determination, the
Assistant Secretary shall publish a notice in the Federal Register. The
notice shall meet the requirements of the remaining paragraphs of this
section. No later than 10 days following the publication of the notice
in the Federal Register, the affected State agency shall publish, or
cause to be published, within the State, reasonable notice containing
the same information.
(d) The notice shall indicate that the plan, or any separable
portion thereof, is in issue before the Assistant Secretary for a
determination as to whether the criteria in section 18(c) of the Act are
being applied in actual operation, and indicate the particular
substantive issues, if any, for consideration in making such
determination.
[[Page 23]]
Where a portion of a plan is in issue for such a determination, the
notice shall specify such portions of the plan as well as those portions
of the plan which are not in issue for the determination.
(e) The notice shall afford interested persons an opportunity to
submit in writing, data, views, and arguments on the proposed 18(e)
determination, and the affected State an opportunity to respond to such
submissions.
(f) The notice shall also state that any interested person or the
affected State may request an informal hearing concerning the proposed
18(e) determination whenever particularized written objections thereto
are filed within 35 days following publication of the notice in the
Federal Register.
(g) If the Assistant Secretary finds that substantial objections are
filed which relate to the proposed 18(e) determination, the Assistant
Secretary shall, and in any other case may, publish a notice of informal
hearing in the Federal Register not later than 30 days after the last
day for filing written views or comments. The notice shall include:
(1) A statement of the time, place and nature of the proceeding;
(2) A specification of the substantial issues which have been raised
and on which an informal hearing has been requested;
(3) The requirement for the filing of an intention to appear at the
hearing, together with a statement of the position to be taken with
regard to the issues specified, and of the evidence to be adduced in
support of the position;
(4) The designation of a presiding officer to conduct the hearing;
and
(5) Any other appropriate provisions with regard to the proceeding.
(h) Not later than 10 days following the publication of the notice
in the Federal Register, required by paragraph (g) of this section, the
affected agency shall publish, or cause to be published, within the
State reasonable notice containing the same information.
Effective Date Note: At 43 FR 11196, Mar. 17, 1978, Sec. 1902.39(a)
was suspended indefinitely, effective January 20, 1978.
Sec. 1902.40 Informal hearing.
(a) Any hearing conducted under this section shall be legislative in
type. However, fairness may require an opportunity for cross-examination
on pertinent issues. The presiding officer is empowered to permit cross-
examination under such circumstances. The essential intent is to provide
an opportunity for participation and comment by interested persons which
can be carried out expeditiously and without rigid procedures which
might unduly impede or protract the 18(e) determination process.
(b) Although the hearing shall be informal and legislative in type,
this section is intended to provide more than the bare essentials of
informal proceedings under 5 U.S.C. 553. The additional requirements are
the following:
(1) The presiding officer shall be a hearing examiner appointed
under 5 U.S.C. 3105.
(2) The presiding officer shall provide an opportunity for cross-
examination on pertinent issues.
(3) The hearing shall be reported verbatim, and a transcript shall
be available to any interested person on such terms as the presiding
officer may provide.
(c) The officer presiding at a hearing shall have all the power
necessary or appropriate to conduct a fair and full hearing, including
the powers:
(1) To regulate the course of the proceedings;
(2) To dispose of procedural requests, objections, and comparable
matters;
(3) To confine the presentation to the issues specified in the
notice of hearing, or, where appropriate, to matters pertinent to the
issue before the Assistant Secretary;
(4) To regulate the conduct of those present at the hearing by
appropriate means;
(5) To take official notice of material facts not appearing in the
evidence in the record, as long as the parties are afforded an
opportunity to show evidence to the contrary;
(6) In his discretion, to keep the record open for a reasonable and
specified time to receive additional written recommendations with
supporting reasons and any additional data, views,
[[Page 24]]
and arguments from any person who has participated in the oral
proceeding.
(d) Upon the completion of the oral presentations, the transcripts
thereof, together with written submissions on the proceedings, exhibits
filed during the hearing, and all posthearing comments, recommendations,
and supporting reasons shall be certified by the officer presiding at
the hearing to the Assistant Secretary.
Sec. 1902.41 Decision.
(a) Within a reasonable time generally within 120 days after the
expiration of the period provided for the submission of written data,
views, and arguments on the issues on which no hearing is held, or
within a reasonable time, generally not to exceed 120 days after the
certification of the record of a hearing, the Assistant Secretary shall
publish his decision in the Federal Register. His decision shall state
whether or not an affirmative 18(e) determination has been made for the
State plan or any separable portion thereof, or whether he intends to
withdraw approval of the plan or any portion thereof pursuant to part
1955 of this chapter. The action of the Assistant Secretary shall be
taken after consideration of all information, including his evaluations
of the actual operations of the plan, and information presented in
written submissions and in any hearings held under this subpart.
(b) Any decision under this section shall incorporate a concise
statement of its grounds and purpose and shall respond to any
substantial issues which may have been raised in written submissions or
at the hearing.
(c) All decisions resulting in an affirmative 18(e) determination
shall contain provisions amending the appropriate subparts of part 1952
of this chapter.
(d) All decisions concerning the Assistant Secretary's determination
under section 18(e) of the Act shall be published in the Federal
Register.
Sec. 1902.42 Effect of affirmative 18(e) determination.
(a) In making an affirmative 18(e) determination, the Assistant
Secretary determines that a State has applied the provisions of its
plan, or any modification thereof, in accordance with the criteria of
section 18(c) of the Act and that the State has applied the provisions
of this part in a manner which renders the actual operations of the
State program ``at least as effective as'' operations under the Federal
program.
(b) In the case of an affirmative 18(e) determination of a separable
portion(s) of a plan, the Assistant Secretary determines that the State
has applied the separable portion(s) of the plan in accordance with the
criteria of section 18(c) of the Act in a manner comparable to Federal
operations covering such portions and that the criteria of this part are
being applied in a manner which renders the actual operations of such
separable portion(s) of the State program ``at least as effective as''
operations of such portions under the Federal program.
(c) Upon making an affirmative 18(e) determination, the standards
promulgated under section 6 of the Act and the enforcement provisions of
section 5(a)(2), 8 (except for the purpose of continuing evaluations
under section 18(f) of the Act), 9, 10, 13 and 17 of the Act shall not
apply with respect to those occupational safety and health issues
covered under the plan for which an affirmative 18(e) determination has
been granted. The Assistant Secretary shall retain his authority under
the above sections for those issues covered in the plan which have not
been granted an affirmative 18(e) determination.
(d) The Assistant Secretary will retain jurisdiction under the
citation and contest provisions of sections 9 and 10 of the Act and the
imminent-danger provisions of section 13 where such proceedings have
been commenced prior to the date of his determination.
Sec. 1902.43 Affirmative 18(e) decision.
(a) In publishing his affirmative 18(e) decision in the Federal
Register the Assistant Secretary's notice shall include, but shall not
be limited to the following:
(1) Those issues under the plan over which the Assistant Secretary
is withdrawing his standards and enforcement authority;
(2) A statement that the Assistant Secretary retains his authority
under
[[Page 25]]
section 11(c) of the Act with regard to complaints alleging
discrimination against employees because of the exercise of any right
afforded to the employee by the Act;
(3) Amendments to the appropriate subpart of part 1952 of this
chapter;
(4) A statement that the Assistant Secretary is not precluded from
revoking his determination and reinstating his standards and enforcement
authority under Sec. 1902.47 et seq., if his continuing evaluations
under section 18(f) of the Act show that the State has substantially
failed to maintain a program which is at least as effective as
operations under the Federal program, or if the State does not submit
program change supplements to its plan to the Assistant Secretary as
required by 29 CFR part 1953.
Sec. 1902.44 Requirements applicable to State plans granted
affirmative 18(e) determinations.
(a) A State whose plan, or modification thereof, has been granted an
affirmative 18(e) determination will be required to maintain a program
within the scope of such determination which will be ``at least as
effective as'' operations under the Federal program in providing
employee safety and health protection at covered workplaces within the
comparable scope of the Federal program. This requirement includes
submitting all required reports to the Assistant Secretary, as well as
submitting supplements to the Assistant Secretary for his approval
whenever there is a change in the State's program, whenever the results
of evaluations conducted under section 18(f) show that some portion of a
State plan has an adverse impact on the operations of the State plan or
whenever the Assistant Secretary determines that any alteration in the
Federal program could have an adverse impact on the ``at least as
effective as'' status of the State program. See part 1953 of this
chapter.
(b) A substantial failure to comply with the requirements of this
section may result in the revocation of the affirmative 18(e)
determination and the resumption of Federal enforcement authority, and
may also result in proceedings for the withdrawal of approval of the
plan or any portion thereof pursuant to part 1955 of this chapter.
Sec. 1902.45 [Reserved]
Sec. 1902.46 Negative 18(e) determination.
(a) This section sets out the procedures which shall be followed
whenever the Assistant Secretary determines that a State's plan, or any
separate portion thereof, has not met the criteria for an affirmative
18(e) determination.
(b) If the Assistant Secretary determines that a State plan, or a
separable portion thereof, has not met the criteria of section 18(c) of
the Act and that actual operations under the plan, or portion thereof,
have not met the criteria for an affirmative determination set forth in
Sec. 1902.37, he shall retain his standards authority under section 6
of the Act and his enforcement authority under sections 5(a)(2), 8, 9,
10, 13, and 17 of the Act for those issues covered under the plan or
such portions of the plan which were subject to his negative
determination.
(c) A decision under this section may result in the commencement of
proceedings for withdrawal of approval of the plan or any separable
portion thereof pursuant to part 1955 of this chapter.
(d) Where the Assistant Secretary determines that operations under a
State plan or any separable portion thereof have not met the criteria
for an affirmative 18(e) determination, but are not of such a nature as
to warrant the initiation of withdrawal proceedings, the Assistant
Secretary may, at his discretion, afford the State a reasonable time to
meet the criteria for an affirmative 18(e) determination after which
time he may initiate proceedings for withdrawal of plan approval. This
discretionary authority will be applied in the following manner:
(1) Upon determining that a State shall be subject to a final 18(e)
determination, the Assistant Secretary shall notify the agency
designated by the State to administer its program, within the State of
his decision that the State's program, or a separable portion thereof,
shall be subject to a final 18(e) determination. The Assistant Secretary
shall give the State a
[[Page 26]]
reasonable time, generally not less than 1 year, in which to meet the
criteria for an affirmative 18(e) determination.
(2) The Assistant Secretary shall also publish a notice in the
Federal Register outlining his reasons for not making an affirmative
18(e) determination at the time. The notice will also set forth the
reasonable time the State was granted to meet the criteria for an
affirmative 18(e) determination and set forth such conditions as the
Assistant Secretary deems proper for the continuation of the State's
plan or such portions subject to this action.
(3) The State shall be afforded an opportunity to agree to the
conditions of the Assistant Secretary's decision.
(4) Upon the expiration of the time granted to a State to meet the
criteria for an affirmative 18(e) determination under paragraph (d)(2)
of this section, the Assistant Secretary may initiate proceedings to
determine whether a State shall be granted an affirmative 18(e)
determination. The procedures outlined in this subpart shall be
applicable to any proceedings initiated under this paragraph.
Procedure for Reconsideration and Revocation of an Affirmative 18(e)
Determination
Sec. 1902.47 Reconsideration of an affirmative 18(e) determination.
(a) The Assistant Secretary may at any time reconsider on his own
initiative or on petition of an interested person his decision granting
an affirmative 18(e) determination.
(b) Such reconsideration shall be based on results of his continuing
evaluation of a State plan after it has been granted an affirmative
18(e) determination.
Sec. 1902.48 The proceeding.
Whenever, as a result of his reconsideration, the Assistant
Secretary proposes to revoke his affirmative 18(e) determination, he
shall follow the procedures in the remaining sections of this subpart.
Sec. 1902.49 General notice.
(a) Whenever the Assistant Secretary proposes to revoke an
affirmative 18(e) determination, he shall publish a notice in the
Federal Register meeting the requirements of the remaining paragraphs of
this section. No later than 10 days following the publication of the
notice in the Federal Register, the affected State agency shall publish,
or cause to be published, reasonable notice within the State containing
the same information.
(b) The notice shall indicate the reasons for the proposed action.
(c) The notice shall afford interested persons including the
affected State, an opportunity to submit in writing, data, views, and
arguments on the proposal within 35 days after publication of the notice
in the Federal Register. The notice shall also provide that any
interested person may request an informal hearing concerning the
proposed revocation whenever particularized written objections thereto
are filed within 35 days following publication of the notice in the
Federal Register. If the Assistant Secretary finds that substantial
objections have been filed, he shall afford an informal hearing on the
proposed revocation under Sec. 1902.50.
(d) The Assistant Secretary may, upon his own initiative, give
notice of an informal hearing affording an opportunity for oral comments
concerning the proposed revocation.
Sec. 1902.50 Informal hearing.
Any informal hearing shall be legislative in type. The rules of
procedure for each hearing shall be those contained in Sec. 1902.40 and
will be published with the notice thereof.
Sec. 1902.51 Certification of the records of a hearing.
Upon completion of an informal hearing, the transcript thereof,
together with written submissions, exhibits filed during the hearing,
and any post-hearing presentations shall be certified by the officer
presiding at the hearing to the Assistant Secretary.
Sec. 1902.52 Decision.
(a) After consideration of all relevant information which has been
presented, the Assistant Secretary shall issue a decision on the
continuation or revocation of the affirmative 18(e) determination.
[[Page 27]]
(b) The decision revoking the determination shall also reflect the
Assistant Secretary's determination that concurrent Federal enforcement
and standards authority will be reinstated within the State for a
reasonable time until he has withdrawn his approval of the plan, or any
separable portion thereof, pursuant to part 1955 of this chapter or he
has determined that the State has met the criteria for an 18(e)
determination pursuant to the applicable procedures of this subpart.
Sec. 1902.53 Publication of decisions.
All decisions on the reconsideration of an affirmative 18(e)
determination shall be published in the Federal Register.

Authority: Sections 8 and 9 of the Occupational Safety and Health
Act of 1970 (29 U.S.C. 657, 658); 5 U.S.C. 553; Secretary of Labor's
Order No. 1-90 (55 FR 9033) or 6-96 (62 FR 111), as applicable.
Section 1903.7 also issued under 5 U.S.C. 553.
Source: 36 FR 17850, Sept. 4, 1971, unless otherwise noted.
Sec. 1903.1 Purpose and scope.
The Williams-Steiger Occupational Safety and Health Act of 1970 (84
Stat. 1590 et seq., 29 U.S.C. 651 et seq.) requires, in part, that every
employer covered under the Act furnish to his employees employment and a
place of employment which are free from recognized hazards that are
causing or are likely to cause death or serious physical harm to his
employees. The Act also requires that employers comply with occupational
safety and health standards promulgated under the Act, and that
employees comply with standards, rules, regulations and orders issued
under the Act which are applicable to their own actions and conduct. The
Act authorizes the Department of Labor to conduct inspections, and to
issue citations and proposed penalties for alleged violations. The Act,
under section 20(b), also authorizes the Secretary of Health, Education,
and Welfare to conduct inspections and to question employers and
employees in connection with research and other related activities. The
Act contains provisions for adjudication of violations, periods
prescribed for the abatement of violations, and proposed penalties by
the Occupational Safety and Health Review Commission, if contested by an
employer or by an employee or authorized representative of employees,
and for judicial review. The purpose of this part 1903 is to prescribe
rules and to set forth general policies for enforcement of the
inspection, citation, and proposed penalty provisions of the Act. In
situations where this part 1903 sets forth general enforcement policies
rather than substantive or procedural rules, such policies may be
modified in specific circumstances where the Secretary or his designee
determines that an alternative course of action would better serve the
objectives of the Act.
Sec. 1903.2 Posting of notice; availability of the Act, regulations
and applicable standards.
(a)(1) Each employer shall post and keep posted a notice or notices,
to be
[[Page 28]]
furnished by the Occupational Safety and Health Administration, U.S.
Department of Labor, informing employees of the protections and
obligations provided for in the Act, and that for assistance and
information, including copies of the Act and of specific safety and
health standards, employees should contact the employer or the nearest
office of the Department of Labor. Such notice or notices shall be
posted by the employer in each establishment in a conspicuous place or
places where notices to employees are customarily posted. Each employer
shall take steps to insure that such notices are not altered, defaced,
or covered by other material.
(2) Where a State has an approved poster informing employees of
their protections and obligations as defined in Sec. 1952.10 of this
chapter, such poster, when posted by employers covered by the State
plan, shall constitute compliance with the posting requirements of
section 8(c)(1) of the Act. Employers whose operations are not within
the issues covered by the State plan must comply with paragraph (a)(1)
of this section.
(3) Reproductions or facsimiles of such Federal or State posters
shall constitute compliance with the posting requirements of section
8(c)(1) of the Act where such reproductions or facsimiles are at least
8\1/2\ inches by 14 inches, and the printing size is at least 10 pt.
Whenever the size of the poster increases, the size of the print shall
also increase accordingly. The caption or heading on the poster shall be
in large type, generally not less than 36 pt.
(b) Establishment means a single physical location where business is
conducted or where services or industrial operations are performed. (For
example: A factory, mill, store, hotel, restaurant, movie theatre, farm,
ranch, bank, sales office, warehouse, or central administrative office.)
Where distinctly separate activities are performed at a single physical
location (such as contract construction activities from the same
physical location as a lumber yard), each activity shall be treated as a
separate physical establishment, and a separate notice or notices shall
be posted in each such establishment, to the extent that such notices
have been furnished by the Occupational Safety and Health
Administration, U.S. Department of Labor. Where employers are engaged in
activities which are physically dispersed, such as agriculture,
construction, transportation, communications, and electric, gas and
sanitary services, the notice or notices required by this section shall
be posted at the location to which employees report each day. Where
employees do not usually work at, or report to, a single establishment,
such as longshoremen, traveling salesmen, technicians, engineers, etc.,
such notice or notices shall be posted at the location from which the
employees operate to carry out their activities. In all cases, such
notice or notices shall be posted in accordance with the requirements of
paragraph (a) of this section.
(c) Copies of the Act, all regulations published in this chapter and
all applicable standards will be available at all Area Offices of the
Occupational Safety and Health Administration, U.S. Department of Labor.
If an employer has obtained copies of these materials, he shall make
them available upon request to any employee or his authorized
representative for review in the establishment where the employee is
employed on the same day the request is made or at the earliest time
mutually convenient to the employee or his authorized representative and
the employer.
(d) Any employer failing to comply with the provisions of this
section shall be subject to citation and penalty in accordance with the
provisions of section 17 of the Act.

Sec. 1903.3 Authority for inspection.
(a) Compliance Safety and Health Officers of the Department of Labor
are authorized to enter without delay and at reasonable times any
factory, plant, establishment, construction site, or other area,
workplace or environment where work is performed by an employee of an
employer; to inspect and investigate during regular working hours and at
other reasonable times, and within reasonable limits and in a
[[Page 29]]
reasonable manner, any such place of employment, and all pertinent
conditions, structures, machines, apparatus, devices, equipment and
materials therein; to question privately any employer, owner, operator,
agent or employee; and to review records required by the Act and
regulations published in this chapter, and other records which are
directly related to the purpose of the inspection. Representatives of
the Secretary of Health, Education, and Welfare are authorized to make
inspections and to question employers and employees in order to carry
out the functions of the Secretary of Health, Education, and Welfare
under the Act. Inspections conducted by Department of Labor Compliance
Safety and Health Officers and representatives of the Secretary of
Health, Education, and Welfare under section 8 of the Act and pursuant
to this part 1903 shall not affect the authority of any State to conduct
inspections in accordance with agreements and plans under section 18 of
the Act.
(b) Prior to inspecting areas containing information which is
classified by an agency of the United States Government in the interest
of national security, Compliance Safety and Health Officers shall have
obtained the appropriate security clearance.
Sec. 1903.4 Objection to inspection.
(a) Upon a refusal to permit the Compliance Safety and Health
Officer, in exercise of his official duties, to enter without delay and
at reasonable times any place of employment or any place therein, to
inspect, to review records, or to question any employer, owner,
operator, agent, or employee, in accordance with Sec. 1903.3 or to
permit a representative of employees to accompany the Compliance Safety
and Health Officer during the physical inspection of any workplace in
accordance with Sec. 1903.8, the Safety and Health Officer shall
terminate the inspection or confine the inspection to other areas,
conditions, structures, machines, apparatus, devices, equipment,
materials, records, or interviews concerning which no objection is
raised. The Compliance Safety and Health Officer shall endeavor to
ascertain the reason for such refusal, and shall immediately report the
refusal and the reason therefor to the Area Director. The Area Director
shall consult with the Regional Solicitor, who shall take appropriate
action, including compulsory process, if necessary.
(b) Compulsory process shall be sought in advance of an attempted
inspection or investigation if, in the judgment of the Area Director and
the Regional Solicitor, circumstances exist which make such
preinspection process desirable or necessary. Some examples of
circumstances in which it may be desirable or necessary to seek
compulsory process in advance of an attempt to inspect or investigate
include (but are not limited to):
(1) When the employer's past practice either implicitly or
explicitly puts the Secretary on notice that a warrantless inspection
will not be allowed;
(2) When an inspection is scheduled far from the local office and
procuring a warrant prior to leaving to conduct the inspection would
avoid, in case of refusal of entry, the expenditure of significant time
and resources to return to the office, obtain a warrant and return to
the worksite;
(3) When an inspection includes the use of special equipment or when
the presence of an expert or experts is needed in order to properly
conduct the inspection, and procuring a warrant prior to an attempt to
inspect would alleviate the difficulties or costs encountered in
coordinating the availability of such equipment or expert.
(c) With the approval of the Regional Administrator and the Regional
Solicitor, compulsory process may also be obtained by the Area Director
or his designee.
(d) For purposes of this section, the term compulsory process shall
mean the institution of any appropriate action, including ex parte
application for an inspection warrant or its equivalent. Ex parte
inspection warrants shall be the preferred form of compulsory process in
all circumstances where compulsory process is relied upon to seek entry
to a workplace under this section.
[45 FR 65923, Oct. 3, 1980]
[[Page 30]]
Sec. 1903.5 Entry not a waiver.
Any permission to enter, inspect, review records, or question any
person, shal not imply or be conditioned upon a waiver of any cause of
action, citation, or penalty under the Act. Compliance Safety and Health
Officers are not authorized to grant any such waiver.
Sec. 1903.6 Advance notice of inspections.
(a) Advance notice of inspections may not be given, except in the
following situations:
(1) In cases of apparent imminent danger, to enable the employer to
abate the danger as quickly as possible;
(2) In circumstances where the inspection can most effectively be
conducted after regular business hours or where special preparations are
necessary for an inspection;
(3) Where necessary to assure the presence of representatives of the
employer and employees or the appropriate personnel needed to aid in the
inspection; and
(4) In other circumstances where the Area Director determines that
the giving of advance notice would enhance the probability of an
effective and thorough inspection.
(b) In the situations described in paragraph (a) of this section,
advance notice of inspections may be given only if authorized by the
Area Director, except that in cases of apparent imminent danger, advance
notice may be given by the Compliance Safety and Health Officer without
such authorization if the Area Director is not immediately available.
When advance notice is given, it shall be the employer's responsibility
promptly to notify the authorized representative of employees of the
inspection, if the identity of such representative is known to the
employer. (See Sec. 1903.8(b) as to situations where there is no
authorized representative of employees.) Upon the request of the
employer, the Compliance Safety and Health Officer will inform the
authorized representative of employees of the inspection, provided that
the employer furnishes the Compliance Safety and Health Officer with the
identity of such representative and with such other information as is
necessary to enable him promptly to inform such representative of the
inspection. An employer who fails to comply with his obligation under
this paragraph promptly to inform the authorized representative of
employees of the inspection or to furnish such information as is
necessary to enable the Compliance Safety and Health Officer promptly to
inform such representative of the inspection, may be subject to citation
and penalty under section 17(c) of the Act. Advance notice in any of the
situations described in paragraph (a) of this section shall not be given
more than 24 hours before the inspection is scheduled to be conducted,
except in apparent imminent danger situations and in other unusual
circumstances.
(c) The Act provides in section 17(f) that any person who gives
advance notice of any inspection to be conducted under the Act, without
authority from the Secretary or his designees, shall, upon conviction,
be punished by fine of not more than $1,000 or by imprisonment for not
more than 6 months, or by both.
Sec. 1903.7 Conduct of inspections.
(a) Subject to the provisions of Sec. 1903.3, inspections shall
take place at such times and in such places of employment as the Area
Director or the Compliance Safety and Health Officer may direct. At the
beginning of an inspection, Compliance Safety and Health Officers shall
present their credentials to the owner, operator, or agent in charge at
the establishment; explain the nature and purpose of the inspection; and
indicate generally the scope of the inspection and the records specified
in Sec. 1903.3 which they wish to review. However, such designation of
records shall not preclude access to additional records specified in
Sec. 1903.3.
(b) Compliance Safety and Health Officers shall have authority to
take environmental samples and to take or obtain photographs related to
the purpose of the inspection, employ other reasonable investigative
techniques, and question privately any employer, owner, operator, agent
or employee of an establishment. (See Sec. 1903.9 on trade secrets.) As
used herein, the term employ other reasonable investigative techniques
includes, but is not limited to, the use of devices to measure employee
[[Page 31]]
exposures and the attachment of personal sampling equipment such as
dosimeters, pumps, badges and other similar devices to employees in
order to monitor their exposures.
(c) In taking photographs and samples, Compliance Safety and Health
Officers shall take reasonable precautions to insure that such actions
with flash, spark-producing, or other equipment would not be hazardous.
Compliance Safety and Health Officers shall comply with all employer
safety and health rules and practices at the establishment being
inspected, and they shall wear and use appropriate protective clothing
and equipment.
(d) The conduct of inspections shall be such as to preclude
unreasonable disruption of the operations of the employer's
establishment.
(e) At the conclusion of an inspection, the Compliance Safety and
Health Officer shall confer with the employer or his representative and
informally advise him of any apparent safety or health violations
disclosed by the inspection. During such conference, the employer shall
be afforded an opportunity to bring to the attention of the Compliance
Safety and Health Officer any pertinent information regarding conditions
in the workplace.
(f) Inspections shall be conducted in accordance with the
requirements of this part.
[36 FR 17850, Sept. 14, 1971, as amended at 47 FR 6533, Feb. 12, 1982;
47 FR 55481, Dec. 10, 1982]
Sec. 1903.8 Representatives of employers and employees.
(a) Compliance Safety and Health Officers shall be in charge of
inspections and questioning of persons. A representative of the employer
and a representative authorized by his employees shall be given an
opportunity to accompany the Compliance Safety and Health Officer during
the physical inspection of any workplace for the purpose of aiding such
inspection. A Compliance Safety and Health Officer may permit additional
employer representatives and additional representatives authorized by
employees to accompany him where he determines that such additional
representatives will further aid the inspection. A different employer
and employee representative may accompany the Compliance Safety and
Health Officer during each different phase of an inspection if this will
not interfere with the conduct of the inspection.
(b) Compliance Safety and Health Officers shall have authority to
resolve all disputes as to who is the representative authorized by the
employer and employees for the purpose of this section. If there is no
authorized representative of employees, or if the Compliance Safety and
Health Officer is unable to determine with reasonable certainty who is
such representative, he shall consult with a reasonable number of
employees concerning matters of safety and health in the workplace.
(c) The representative(s) authorized by employees shall be an
employee(s) of the employer. However, if in the judgment of the
Compliance Safety and Health Officer, good cause has been shown why
accompaniment by a third party who is not an employee of the employer
(such as an industrial hygienist or a safety engineer) is reasonably
necessary to the conduct of an effective and thorough physical
inspection of the workplace, such third party may accompany the
Compliance Safety and Health Officer during the inspection.
(d) Compliance Safety and Health Officers are authorized to deny the
right of accompaniment under this section to any person whose conduct
interferes with a fair and orderly inspection. The right of
accompaniment in areas containing trade secrets shall be subject to the
provisions of Sec. 1903.9(d). With regard to information classified by
an agency of the U.S. Government in the interest of national security,
only persons authorized to have access to such information may accompany
a Compliance Safety and Health Officer in areas containing such
information.
Sec. 1903.9 Trade secrets.
(a) Section 15 of the Act provides: ``All information reported to or
otherwise obtained by the Secretary or his representative in connection
with any inspection or proceeding under this Act which contains or which
might reveal a trade secret referred to in section 1905 of title 18 of
the United States Code
[[Page 32]]
shall be considered confidential for the purpose of that section, except
that such information may be disclosed to other officers or employees
concerned with carrying out this Act or when relevant in any proceeding
under this Act. In any such proceeding the Secretary, the Commission, or
the court shall issue such orders as may be appropriate to protect the
confidentiality of trade secrets.'' Section 15 of the Act is considered
a statute within the meaning of section 552(b)(3) of title 5 of the
United States Code, which exempts from the disclosure requirements
matters that are ``specifically exempted from disclosure by statute.''
(b) Section 1905 of title 18 of the United States Code provides:
``Whoever, being an officer or employee of the United States or of any
department or agency thereof, publishes, divulges, discloses, or makes
known in any manner or to any extent not authorized by law any
information coming to him in the course of his employment or official
duties or by reason of any examination or investigation made by, or
return, report or record made to or filed with, such department or
agency or officer or employee thereof, which information concerns or
relates to the trade secrets, processes, operations, style of work, or
apparatus, or to the identity, confidential statistical data, amount or
source of any income, profits, losses, or expenditures of any person,
firm, partnership, corporation, or association; or permits any income
return or copy thereof or any book containing any abstract or
particulars thereof to be seen or examined by any person except as
provided by law; shall be fined not more than $1,000, or imprisoned not
more than 1 year, or both; and shall be removed from office or
employment.''
(c) At the commencement of an inspection, the employer may identify
areas in the establishment which contain or which might reveal a trade
secret. If the Compliance Safety and Health Officer has no clear reason
to question such identification, information obtained in such areas,
including all negatives and prints of photographs, and environmental
samples, shall be labeled ``confidential--trade secret'' and shall not
be disclosed except in accordance with the provisions of section 15 of
the Act.
(d) Upon the request of an employer, any authorized representative
of employees under Sec. 1903.8 in an area containing trade secrets
shall be an employee in that area or an employee authorized by the
employer to enter that area. Where there is no such representative or
employee, the Compliance Safety and Health Officer shall consult with a
reasonable number of employees who work in that area concerning matters
of safety and health.
Sec. 1903.10 Consultation with employees.
Compliance Safety and Health Officers may consult with employees
concerning matters of occupational safety and health to the extent they
deem necessary for the conduct of an effective and thorough inspection.
During the course of an inspection, any employee shall be afforded an
opportunity to bring any violation of the Act which he has reason to
believe exists in the workplace to the attention of the Compliance
Safety and Health Officer.
Sec. 1903.11 Complaints by employees.
(a) Any employee or representative of employees who believe that a
violation of the Act exists in any workplace where such employee is
employed may request an inspection of such workplace by giving notice of
the alleged violation to the Area Director or to a Compliance Safety and
Health Officer. Any such notice shall be reduced to writing, shall set
forth with reasonable particularity the grounds for the notice, and
shall be signed by the employee or representative of employees. A copy
shall be provided the employer or his agent by the Area Director or
Compliance Safety and Health Officer no later than at the time of
inspection, except that, upon the request of the person giving such
notice, his name and the names of individual employees referred to
therein shall not appear in such copy or on any record published,
released, or made available by the Department of Labor.
(b) If upon receipt of such notification the Area Director
determines that the complaint meets the requirements set forth in
paragraph (a) of this section, and that there are reasonable
[[Page 33]]
grounds to believe that the alleged violation exists, he shall cause an
inspection to be made as soon as practicable, to determine if such
alleged violation exists. Inspections under this section shall not be
limited to matters referred to in the complaint.
(c) Prior to or during any inspection of a workplace, any employee
or representative of employees employed in such workplace may notify the
Compliance Safety and Health Officer, in writing, of any violation of
the Act which they have reason to believe exists in such workplace. Any
such notice shall comply with the requirements of paragraph (a) of this
section.
(d) Section 11(c)(1) of the Act provides: ``No person shall
discharge or in any manner discriminate against any employee because
such employee has filed any complaint or instituted or caused to be
instituted any proceeding under or related to this Act or has testified
or is about to testify in any such proceeding or because of the exercise
by such employee on behalf of himself or others of any right afforded by
this Act.''

[36 FR 17850, Sept. 4, 1973, as amended at 54 FR 24333, June 7, 1989]
Sec. 1903.12 Inspection not warranted; informal review.
(a) If the Area Director determines that an inspection is not
warranted because there are no reasonable grounds to believe that a
violation or danger exists with respect to a complaint under Sec.
1903.11, he shall notify the complaining party in writing of such
determination. The complaining party may obtain review of such
determination by submitting a written statement of position with the
Assistant Regional Director and, at the same time, providing the
employer with a copy of such statement by certified mail. The employer
may submit an opposing written statement of position with the Assistant
Regional Director and, at the same time, provide the complaining party
with a copy of such statement by certified mail. Upon the request of the
complaining party or the employer, the Assistant Regional Director, at
his discretion, may hold an informal conference in which the complaining
party and the employer may orally present their views. After considering
all written and oral views presented, the Assistant Regional Director
shall affirm, modify, or reverse the determination of the Area Director
and furnish the complaining party and the employer and written
notification of this decision and the reasons therefor. The decision of
the Assistant Regional Director shall be final and not subject to
further review.
(b) If the Area Director determines that an inspection is not
warranted because the requirements of Sec. 1903.11(a) have not been
met, he shall notify the complaining party in writing of such
determination. Such determination shall be without prejudice to the
filing of a new complaint meeting the requirements of Sec. 1903.11(a).
Sec. 1903.13 Imminent danger.
Whenever and as soon as a Compliance Safety and Health Officer
concludes on the basis of an inspection that conditions or practices
exist in any place of employment which could reasonably be expected to
cause death or serious physical harm immediately or before the imminence
of such danger can be eliminated through the enforcement procedures
otherwise provided by the Act, he shall inform the affected employees
and employers of the danger and that he is recommending a civil action
to restrain such conditions or practices and for other appropriate
relief in accordance with the provisions of section 13(a) of the Act.
Appropriate citations and notices of proposed penalties may be issued
with respect to an imminent danger even though, after being informed of
such danger by the Compliance Safety and Health Officer, the employer
immediately eliminates the imminence of the danger and initiates steps
to abate such danger.
Sec. 1903.14 Citations; notices of de minimis violations; policy
regarding employee rescue activities.
(a) The Area Director shall review the inspection report of the
Compliance Safety and Health Officer. If, on the basis of the report the
Area Director believes that the employer has violated a requirement of
section 5 of the
[[Page 34]]
Act, of any standard, rule or order promulgated pursuant to section 6 of
the Act, or of any substantive rule published in this chapter, he shall,
if appropriate, consult with the Regional Solicitor, and he shall issue
to the employer either a citation or a notice of de minimis violations
which have no direct or immediate relationship to safety or health. An
appropriate citation or notice of de minimis violations shall be issued
even though after being informed of an alleged violation by the
Compliance Safety and Health Officer, the employer immediately abates,
or initiates steps to abate, such alleged violation. Any citation or
notice of de minimis violations shall be issued with reasonable
promptness after termination of the inspection. No citation may be
issued under this section after the expiration of 6 months following the
occurrence of any alleged violation.
(b) Any citation shall describe with particularity the nature of the
alleged violation, including a reference to the provision(s) of the Act,
standard, rule, regulation, or order alleged to have been violated. Any
citation shall also fix a reasonable time or times for the abatement of
the alleged violation.
(c) If a citation or notice of de minimis violations is issued for a
violation alleged in a request for inspection under Sec. 1903.11(a) or
a notification of violation under Sec. 1903.11(c), a copy of the
citation or notice of de minimis violations shall also be sent to the
employee or representative of employees who made such request or
notification.
(d) After an inspection, if the Area Director determines that a
citation is not warranted with respect to a danger or violation alleged
to exist in a request for inspection under Sec. 1903.11(a) or a
notification of violation under Sec. 1903.11(c), the informal review
procedures prescribed in Sec. 1903.12(a) shall be applicable. After
considering all views presented, the Assistant Regional Director shall
affirm the determination of the Area Director, order a reinspection, or
issue a citation if he believes that the inspection disclosed a
violation. The Assistant Regional Director shall furnish the complaining
party and the employer with written notification of his determination
and the reasons therefor. The determination of the Assistant Regional
Director shall be final and not subject to review.
(e) Every citation shall state that the issuance of a citation does
not constitute a finding that a violation of the Act has occurred unless
there is a failure to contest as provided for in the Act or, if
contested, unless the citation is affirmed by the Review Commission.
(f) No citation may be issued to an employer because of a rescue
activity undertaken by an employee of that employer with respect to an
individual in imminent danger unless:
(1)(i) Such employee is designated or assigned by the employer to
have responsibility to perform or assist in rescue operations, and
(ii) The employer fails to provide protection of the safety and
health of such employee, including failing to provide appropriate
training and rescue equipment; or
(2)(i) Such employee is directed by the employer to perform rescue
activities in the course of carrying out the employee's job duties, and
(ii) The employer fails to provide protection of the safety and
health of such employee, including failing to provide appropriate
training and rescue equipment; or
(3)(i) Such employee is employed in a workplace that requires the
employee to carry out duties that are directly related to a workplace
operation where the likelihood of life-threatening accidents is
foreseeable, such as a workplace operation where employees are located
in confined spaces or trenches, handle hazardous waste, respond to
emergency situations, perform excavations, or perform construction over
water; and
(ii) Such employee has not been designated or assigned to perform or
assist in rescue operations and voluntarily elects to rescue such an
individual; and
(iii) The employer has failed to instruct employees not designated
or assigned to perform or assist in rescue operations of the
arrangements for rescue, not to attempt rescue, and of the hazards of
attempting rescue without adequate training or equipment.
(4) For purposes of this policy, the term ``imminent danger'' means
the existence of any condition or practice
[[Page 35]]
that could reasonably be expected to cause death or serious physical
harm before such condition or practice can be abated.
[36 FR 17850, Sept. 4, 1971, as amended at 59 FR 66613, Dec. 27, 1994]
Sec. 1903.14a Petitions for modification of abatement date.
(a) An employer may file a petition for modification of abatement
date when he has made a good faith effort to comply with the abatement
requirements of a citation, but such abatement has not been completed
because of factors beyond his reasonable control.
(b) A petition for modification of abatement date shall be in
writing and shall include the following information:
(1) All steps taken by the employer, and the dates of such action,
in an effort to achieve compliance during the prescribed abatement
period.
(2) The specific additional abatement time necessary in order to
achieve compliance.
(3) The reasons such additional time is necessary, including the
unavailability of professional or technical personnel or of materials
and equipment, or because necessary construction or alteration of
facilities cannot be completed by the original abatement date.
(4) All available interim steps being taken to safeguard the
employees against the cited hazard during the abatement period.
(5) A certification that a copy of the petition has been posted and,
if appropriate, served on the authorized representative of affected
employees, in accordance with paragraph (c)(1) of this section and a
certification of the date upon which such posting and service was made.
(c) A petition for modification of abatement date shall be filed
with the Area Director of the United States Department of Labor who
issued the citation no later than the close of the next working day
following the date on which abatement was originally required. A later-
filed petition shall be accompanied by the employer's statement of
exceptional circumstances explaining the delay.
(1) A copy of such petition shall be posted in a conspicuous place
where all affected employees will have notice thereof or near such
location where the violation occurred. The petition shall remain posted
for a period of ten (10) working days. Where affected employees are
represented by an authorized representative, said representative shall
be served with a copy of such petition.
(2) Affected employees or their representatives may file an
objection in writing to such petition with the aforesaid Area Director.
Failure to file such objection within ten (10) working days of the date
of posting of such petition or of service upon an authorized
representative shall constitute a waiver of any further right to object
to said petition.
(3) The Secretary or his duly authorized agent shall have the
authority to approve any petition for modification of abatement date
filed pursuant to paragraphs (b) and (c) of this section. Such
uncontested petitions shall become final orders pursuant to sections 10
(a) and (c) of the Act.
(4) The Secretary or his authorized representative shall not
exercise his approval power until the expiration of fifteen (15) working
days from the date the petition was posted or served pursuant to
paragraphs (c) (1) and (2) of this section by the employer.
(d) Where any petition is objected to by the Secretary or affected
employees, the petition, citation, and any objections shall be forwarded
to the Commission within three (3) working days after the expiration of
the fifteen (15) day period set out in paragraph (c)(4) of this section.
[40 FR 6334, Feb. 11, 1975; 40 FR 11351, Mar. 11, 1975]
Sec. 1903.15 Proposed penalties.
(a) After, or concurrent with, the issuance of a citation, and
within a reasonable time after the termination of the inspection, the
Area Director shall notify the employer by certified mail or by personal
service by the Compliance Safety and Health Officer of the proposed
penalty under section 17 of the Act, or that no penalty is being
proposed. Any notice of proposed penalty shall state that the proposed
[[Page 36]]
penalty shall be deemed to be the final order of the Review Commission
and not subject to review by any court or agency unless, within 15
working days from the date of receipt of such notice, the employer
notifies the Area Director in writing that he intends to contest the
citation or the notification of proposed penalty before the Review
Commission.
(b) The Area Director shall determine the amount of any proposed
penalty, giving due consideration to the appropriateness of the penalty
with respect to the size of the business of the employer being charged,
the gravity of the violation, the good faith of the employer, and the
history of previous violations, in accordance with the provisions of
section 17 of the Act.
(c) Appropriate penalties may be proposed with respect to an alleged
violation even though after being informed of such alleged violation by
the Compliance Safety and Health Officer, the employer immediately
abates, or initiates steps to abate, such alleged violation. Penalties
shall not be proposed for de minimis violations which have no direct or
immediate relationship to safety or health.
Sec. 1903.16 Posting of citations.
(a) Upon receipt of any citation under the Act, the employer shall
immediately post such citation, or a copy thereof, unedited, at or near
each place an alleged violation referred to in the citation occurred,
except as provided below. Where, because of the nature of the employer's
operations, it is not practicable to post the citation at or near each
place of alleged violation, such citation shall be posted, unedited, in
a prominent place where it will be readily observable by all affected
employees. For example, where employers are engaged in activities which
are physically dispersed (see Sec. 1903.2(b)), the citation may be
posted at the location to which employees report each day. Where
employees do not primarily work at or report to a single location (see
Sec. 1903.2(b)), the citation may be posted at the location from which
the employees operate to carry out their activities. The employer shall
take steps to ensure that the citation is not altered, defaced, or
covered by other material. Notices of de minimis violations need not be
posted.
(b) Each citation, or a copy thereof, shall remain posted until the
violation has been abated, or for 3 working days, whichever is later.
The filing by the employer of a notice of intention to contest under
Sec. 1903.17 shall not affect his posting responsibility under this
section unless and until the Review Commission issues a final order
vacating the citation.
(c) An employer to whom a citation has been issued may post a notice
in the same location where such citation is posted indicating that the
citation is being contested before the Review Commission, and such
notice may explain the reasons for such contest. The employer may also
indicate that specified steps have been taken to abate the violation.
(d) Any employer failing to comply with the provisions of paragraphs
(a) and (b) of this section shall be subject to citation and penalty in
accordance with the provisions of section 17 of the Act.
Sec. 1903.17 Employer and employee contests before the Review
Commission.
(a) Any employer to whom a citation or notice of proposed penalty
has been issued may, under section 10(a) of the Act, notify the Area
Director in writing that he intends to contest such citation or proposed
penalty before the Review Commission. Such notice of intention to
contest shall be postmarked within 15 working days of the receipt by the
employer of the notice of proposed penalty. Every notice of intention to
contest shall specify whether it is directed to the citation or to the
proposed penalty, or both. The Area Director shall immediately transmit
such notice to the Review Commission in accordance with the rules of
procedure prescribed by the Commission.
(b) Any employee or representative of employees of an employer to
whom a citation has been issued may, under section 10(c) of the Act,
file a written notice with the Area Director alleging that the period of
time fixed in the citation for the abatement of the violation is
unreasonable. Such notice shall be postmarked within 15 working days
[[Page 37]]
of the receipt by the employer of the notice of proposed penalty or
notice that no penalty is being proposed. The Area Director shall
immediately transmit such notice to the Review Commission in accordance
with the rules of procedure prescribed by the Commission.
Sec. 1903.18 Failure to correct a violation for which a citation
has been issued.
(a) If an inspection discloses that an employer has failed to
correct an alleged violation for which a citation has been issued within
the period permitted for its correction, the Area Director shall, if
appropriate, consult with the Regional Solicitor, and he shall notify
the employer by certified mail or by personal service by the Compliance
Safety and Health Officer of such failure and of the additional penalty
proposed under section 17(d) of the Act by reason of such failure. The
period for the correction of a violation for which a citation has been
issued shall not begin to run until the entry of a final order of the
Review Commission in the case of any review proceedings initiated by the
employer in good faith and not solely for delay or avoidance of
penalties.
(b) Any employer receiving a notification of failure to correct a
violation and of proposed additional penalty may, under section 10(b) of
the Act, notify the Area Director in writing that he intends to contest
such notification or proposed additional penalty before the Review
Commission. Such notice of intention to contest shall be postmarked
within 15 working days of the receipt by the employer of the
notification of failure to correct a violation and of proposed
additional penalty. The Area Director shall immediately transmit such
notice to the Review Commission in accordance with the rules of
procedure prescribed by the Commission.
(c) Each notification of failure to correct a violation and of
proposed additional penalty shall state that it shall be deemed to be
the final order of the Review Commission and not subject to review by
any court or agency unless, within 15 working days from the date of
receipt of such notification, the employer notifies the Area Director in
writing that he intends to contest the notification or the proposed
additional penalty before the Review Commission.
Sec. 1903.19 Abatement verification.
Purpose. OSHA's inspections are intended to result in the abatement
of violations of the Occupational Safety and Health Act of 1970 (the OSH
Act). This section sets forth the procedures OSHA will use to ensure
abatement. These procedures are tailored to the nature of the violation
and the employer's abatement actions.
(a) Scope and application. This section applies to employers who
receive a citation for a violation of the Occupational Safety and Health
Act.
(b) Definitions--(1) Abatement means action by an employer to comply
with a cited standard or regulation or to eliminate a recognized hazard
identified by OSHA during an inspection.
(2) Abatement date means:
(i) For an uncontested citation item, the later of:
(A) The date in the citation for abatement of the violation;
(B) The date approved by OSHA or established in litigation as a
result of a petition for modification of the abatement date (PMA); or
(C) The date established in a citation by an informal settlement
agreement.
(ii) For a contested citation item for which the Occupational Safety
and Health Review Commission (OSHRC) has issued a final order affirming
the violation, the later of:
(A) The date identified in the final order for abatement; or
(B) The date computed by adding the period allowed in the citation
for abatement to the final order date;
(C) The date established by a formal settlement agreement.
(3) Affected employees means those employees who are exposed to the
hazard(s) identified as violation(s) in a citation.
(4) Final order date means:
(i) For an uncontested citation item, the fifteenth working day
after the employer's receipt of the citation;
(ii) For a contested citation item:
[[Page 38]]
(A) The thirtieth day after the date on which a decision or order of
a commission administrative law judge has been docketed with the
commission, unless a member of the commission has directed review; or
(B) Where review has been directed, the thirtieth day after the date
on which the Commission issues its decision or order disposing of all or
pertinent part of a case; or
(C) The date on which a federal appeals court issues a decision
affirming the violation in a case in which a final order of OSHRC has
been stayed.
(5) Movable equipment means a hand-held or non-hand-held machine or
device, powered or unpowered, that is used to do work and is moved
within or between worksites.
(c) Abatement certification. (1) Within 10 calendar days after the
abatement date, the employer must certify to OSHA (the Agency) that each
cited violation has been abated, except as provided in paragraph (c)(2)
of this section.
(2) The employer is not required to certify abatement if the OSHA
Compliance Officer, during the on-site portion of the inspection:
(i) Observes, within 24 hours after a violation is identified, that
abatement has occurred; and
(ii) Notes in the citation that abatement has occurred.
(3) The employer's certification that abatement is complete must
include, for each cited violation, in addition to the information
required by paragraph (h) of this section, the date and method of
abatement and a statement that affected employees and their
representatives have been informed of the abatement.
Note to paragraph (c): Appendix A contains a sample Abatement
Certification Letter.
(d) Abatement documentation. (1) The employer must submit to the
Agency, along with the information on abatement certification required
by paragraph (c)(3) of this section, documents demonstrating that
abatement is complete for each willful or repeat violation and for any
serious violation for which the Agency indicates in the citation that
such abatement documentation is required.
(2) Documents demonstrating that abatement is complete may include,
but are not limited to, evidence of the purchase or repair of equipment,
photographic or video evidence of abatement, or other written records.
(e) Abatement plans. (1) The Agency may require an employer to
submit an abatement plan for each cited violation (except an other-than-
serious violation) when the time permitted for abatement is more than 90
calendar days. If an abatement plan is required, the citation must so
indicate.
(2) The employer must submit an abatement plan for each cited
violation within 25 calendar days from the final order date when the
citation indicates that such a plan is required. The abatement plan must
identify the violation and the steps to be taken to achieve abatement,
including a schedule for completing abatement and, where necessary, how
employees will be protected from exposure to the violative condition in
the interim until abatement is complete.
Note to paragraph (e): Appendix B contains a Sample Abatement Plan
form.
(f) Progress reports. (1) An employer who is required to submit an
abatement plan may also be required to submit periodic progress reports
for each cited violation. The citation must indicate:
(i) That periodic progress reports are required and the citation
items for which they are required;
(ii) The date on which an initial progress report must be submitted,
which may be no sooner than 30 calendar days after submission of an
abatement plan;
(iii) Whether additional progress reports are required; and
(iv) The date(s) on which additional progress reports must be
submitted.
(2) For each violation, the progress report must identify, in a
single sentence if possible, the action taken to achieve abatement and
the date the action was taken.
Note to paragraph (f): Appendix B contains a Sample Progress Report
form.
(g) Employee notification. (1) The employer must inform affected
employees and their representative(s) about abatement activities covered
by this
[[Page 39]]
section by posting a copy of each document submitted to the Agency or a
summary of the document near the place where the violation occurred.
(2) Where such posting does not effectively inform employees and
their representatives about abatement activities (for example, for
employers who have mobile work operations), the employer must:
(i) Post each document or a summary of the document in a location
where it will be readily observable by affected employees and their
representatives; or
(ii) Take other steps to communicate fully to affected employees and
their representatives about abatement activities.
(3) The employer must inform employees and their representatives of
their right to examine and copy all abatement documents submitted to the
Agency.
(i) An employee or an employee representative must submit a request
to examine and copy abatement documents within 3 working days of
receiving notice that the documents have been submitted.
(ii) The employer must comply with an employee's or employee
representative's request to examine and copy abatement documents within
5 working days of receiving the request.
(4) The employer must ensure that notice to employees and employee
representatives is provided at the same time or before the information
is provided to the Agency and that abatement documents are:
(i) Not altered, defaced, or covered by other material; and
(ii) Remain posted for three working days after submission to the
Agency.
(h) Transmitting abatement documents. (1) The employer must include,
in each submission required by this section, the following information:
(i) The employer's name and address;
(ii) The inspection number to which the submission relates;
(iii) The citation and item numbers to which the submission relates;
(iv) A statement that the information submitted is accurate; and
(v) The signature of the employer or the employer's authorized
representative.
(2) The date of postmark is the date of submission for mailed
documents. For documents transmitted by other means, the date the Agency
receives the document is the date of submission.
(i) Movable equipment. (1) For serious, repeat, and willful
violations involving movable equipment, the employer must attach a
warning tag or a copy of the citation to the operating controls or to
the cited component of equipment that is moved within the worksite or
between worksites.
Note to paragraph (i)(1): Attaching a copy of the citation to the
equipment is deemed by OSHA to meet the tagging requirement of paragraph
(i)(1) of this section as well as the posting requirement of 29 CFR
1903.16.
(2) The employer must use a warning tag that properly warns
employees about the nature of the violation involving the equipment and
identifies the location of the citation issued.
Note to paragraph (i)(2): Non-Mandatory Appendix C contains a sample
tag that employers may use to meet this requirement.
(3) If the violation has not already been abated, a warning tag or
copy of the citation must be attached to the equipment:
(i) For hand-held equipment, immediately after the employer receives
the citation; or
(ii) For non-hand-held equipment, prior to moving the equipment
within or between worksites.
(4) For the construction industry, a tag that is designed and used
in accordance with 29 CFR 1926.20(b)(3) and 29 CFR 1926.200(h) is deemed
by OSHA to meet the requirements of this section when the information
required by paragraph (i)(2) is included on the tag.
(5) The employer must assure that the tag or copy of the citation
attached to movable equipment is not altered, defaced, or covered by
other material.
(6) The employer must assure that the tag or copy of the citation
attached to movable equipment remains attached until:
(i) The violation has been abated and all abatement verification
documents required by this regulation have been submitted to the Agency;
[[Page 40]]
(ii) The cited equipment has been permanently removed from service
or is no longer within the employer's control; or
(iii) The Commission issues a final order vacating the citation.

Source: 66 FR 6122, Jan. 19, 2001, unless otherwise noted.
Subpart A_Purpose
Sec. 1904.0 Purpose.
The purpose of this rule (Part 1904) is to require employers to
record and report work-related fatalities, injuries and illnesses.
Note to Sec. 1904.0: Recording or reporting a work-related injury,
illness, or fatality does not mean that the employer or employee was at
fault, that an OSHA rule has been violated, or that the employee is
eligible for workers' compensation or other benefits.
Subpart B_Scope
Note to Subpart B: All employers covered by the Occupational Safety
and Health Act (OSH Act) are covered by these Part 1904 regulations.
However, most employers do not have to keep OSHA injury and illness
records unless OSHA or the Bureau of Labor Statistics (BLS) informs them
in writing that they must keep records. For example, employers with 10
or fewer employees and business establishments in certain industry
classifications are partially exempt from keeping OSHA injury and
illness records.
Sec. 1904.1 Partial exemption for employers with 10 or fewer employees.
(a) Basic requirement. (1) If your company had ten (10) or fewer
employees at all times during the last calendar year, you do not need to
keep OSHA injury and illness records unless OSHA or the BLS informs you
in writing that you must keep records under Sec. 1904.41 or Sec.
1904.42. However, as required by Sec. 1904.39, all employers covered by
the OSH Act must report to OSHA any workplace incident that results in a
fatality or the hospitalization of three or more employees.
[[Page 44]]
(2) If your company had more than ten (10) employees at any time
during the last calendar year, you must keep OSHA injury and illness
records unless your establishment is classified as a partially exempt
industry under Sec. 1904.2.
(b) Implementation--(1) Is the partial exemption for size based on
the size of my entire company or on the size of an individual business
establishment? The partial exemption for size is based on the number of
employees in the entire company.
(2) How do I determine the size of my company to find out if I
qualify for the partial exemption for size? To determine if you are
exempt because of size, you need to determine your company's peak
employment during the last calendar year. If you had no more than 10
employees at any time in the last calendar year, your company qualifies
for the partial exemption for size.
Sec. 1904.2 Partial exemption for establishments in certain industries.
(a) Basic requirement. (1) If your business establishment is
classified in a specific low hazard retail, service, finance, insurance
or real estate industry listed in Appendix A to this Subpart B, you do
not need to keep OSHA injury and illness records unless the government
asks you to keep the records under Sec. 1904.41 or Sec. 1904.42.
However, all employers must report to OSHA any workplace incident that
results in a fatality or the hospitalization of three or more employees
(see Sec. 1904.39).
(2) If one or more of your company's establishments are classified
in a non-exempt industry, you must keep OSHA injury and illness records
for all of such establishments unless your company is partially exempted
because of size under Sec. 1904.1.
(b) Implementation--(1) Does the partial industry classification
exemption apply only to business establishments in the retail, services,
finance, insurance or real estate industries (SICs 52-89)? Yes, business
establishments classified in agriculture; mining; construction;
manufacturing; transportation; communication, electric, gas and sanitary
services; or wholesale trade are not eligible for the partial industry
classification exemption.
(2) Is the partial industry classification exemption based on the
industry classification of my entire company or on the classification of
individual business establishments operated by my company? The partial
industry classification exemption applies to individual business
establishments. If a company has several business establishments engaged
in different classes of business activities, some of the company's
establishments may be required to keep records, while others may be
exempt.
(3) How do I determine the Standard Industrial Classification code
for my company or for individual establishments? You determine your
Standard Industrial Classification (SIC) code by using the Standard
Industrial Classification Manual, Executive Office of the President,
Office of Management and Budget. You may contact your nearest OSHA
office or State agency for help in determining your SIC.
Sec. 1904.3 Keeping records for more than one agency.
If you create records to comply with another government agency's
injury and illness recordkeeping requirements, OSHA will consider those
records as meeting OSHA's Part 1904 recordkeeping requirements if OSHA
accepts the other agency's records under a memorandum of understanding
with that agency, or if the other agency's records contain the same
information as this Part 1904 requires you to record. You may contact
your nearest OSHA office or State agency for help in determining whether
your records meet OSHA's requirements.
Non-Mandatory Appendix A to Subpart B of Part 1904--Partially Exempt
Industries
Employers are not required to keep OSHA injury and illness records
for any establishment classified in the following Standard Industrial
Classification (SIC) codes, unless they are asked in writing to do so by
OSHA, the Bureau of Labor Statistics ( BLS), or a state agency operating
under the authority of OSHA or the BLS. All employers, including those
partially exempted by reason of company size or industry classification,
must report to OSHA any workplace incident
[[Page 45]]
that results in a fatality or the hospitalization of three or more
employees (see Sec. 1904.39).

Sec. 1904.12.
(b) Implementation--(1) What sections of this rule describe
recording criteria for recording work-related injuries and illnesses?
The table below indicates which sections of the rule address each topic.
(i) Determination of work-relatedness. See Sec. 1904.5.
(ii) Determination of a new case. See Sec. 1904.6.
(iii) General recording criteria. See Sec. 1904.7.
(iv) Additional criteria. (Needlestick and sharps injury cases,
tuberculosis cases, hearing loss cases, medical removal cases, and
musculoskeletal disorder cases). See Sec. 1904.8 through Sec. 1904.12.
(2) How do I decide whether a particular injury or illness is
recordable? The decision tree for recording work-related injuries and
illnesses below shows the steps involved in making this determination.
[[Page 46]]
[GRAPHIC] [TIFF OMITTED] TR19JA01.098
Sec. 1904.5 Determination of work-relatedness.
(a) Basic requirement. You must consider an injury or illness to be
work-related if an event or exposure in the work environment either
caused or contributed to the resulting condition or significantly
aggravated a pre-existing injury or illness. Work-relatedness is
presumed for injuries and illnesses resulting from events or exposures
occurring in the work environment, unless an exception in Sec.
1904.5(b)(2) specifically applies.
(b) Implementation. (1) What is the ``work environment''? OSHA
defines the work environment as ``the establishment and other locations
where one or more employees are working or are present as a condition of
their employment. The work environment includes not only physical
locations, but also the equipment or materials used by the employee
during the course of his or her work.''
(2) Are there situations where an injury or illness occurs in the
work environment and is not considered work-related? Yes, an injury or
illness occurring in the work environment that falls under one of the
following exceptions is not work-related, and therefore is not
recordable.
[[Page 47]]
------------------------------------------------------------------------
You are not required to record injuries and
1904.5(b)(2) illnesses if . . .
------------------------------------------------------------------------
(i).................. At the time of the injury or illness, the
employee was present in the work environment as
a member of the general public rather than as an
employee.
(ii)................. The injury or illness involves signs or symptoms
that surface at work but result solely from a
non-work-related event or exposure that occurs
outside the work environment.
(iii)................ The injury or illness results solely from
voluntary participation in a wellness program or
in a medical, fitness, or recreational activity
such as blood donation, physical examination,
flu shot, exercise class, racquetball, or
baseball.
(iv)................. The injury or illness is solely the result of an
employee eating, drinking, or preparing food or
drink for personal consumption (whether bought
on the employer's premises or brought in). For
example, if the employee is injured by choking
on a sandwich while in the employer's
establishment, the case would not be considered
work-related.
Note: If the employee is made ill by ingesting
food contaminated by workplace contaminants
(such as lead), or gets food poisoning from food
supplied by the employer, the case would be
considered work-related.
(v).................. The injury or illness is solely the result of an
employee doing personal tasks (unrelated to
their employment) at the establishment outside
of the employee's assigned working hours.
(vi)................. The injury or illness is solely the result of
personal grooming, self medication for a non-
work-related condition, or is intentionally self-
inflicted.
(vii)................ The injury or illness is caused by a motor
vehicle accident and occurs on a company parking
lot or company access road while the employee is
commuting to or from work.
(viii)............... The illness is the common cold or flu (Note:
contagious diseases such as tuberculosis,
brucellosis, hepatitis A, or plague are
considered work-related if the employee is
infected at work).
(ix)................. The illness is a mental illness. Mental illness
will not be considered work-related unless the
employee voluntarily provides the employer with
an opinion from a physician or other licensed
health care professional with appropriate
training and experience (psychiatrist,
psychologist, psychiatric nurse practitioner,
etc.) stating that the employee has a mental
illness that is work-related.
------------------------------------------------------------------------
(3) How do I handle a case if it is not obvious whether the
precipitating event or exposure occurred in the work environment or
occurred away from work? In these situations, you must evaluate the
employee's work duties and environment to decide whether or not one or
more events or exposures in the work environment either caused or
contributed to the resulting condition or significantly aggravated a
pre-existing condition.
(4) How do I know if an event or exposure in the work environment
``significantly aggravated'' a preexisting injury or illness? A
preexisting injury or illness has been significantly aggravated, for
purposes of OSHA injury and illness recordkeeping, when an event or
exposure in the work environment results in any of the following:
(i) Death, provided that the preexisting injury or illness would
likely not have resulted in death but for the occupational event or
exposure.
(ii) Loss of consciousness, provided that the preexisting injury or
illness would likely not have resulted in loss of consciousness but for
the occupational event or exposure.
(iii) One or more days away from work, or days of restricted work,
or days of job transfer that otherwise would not have occurred but for
the occupational event or exposure.
(iv) Medical treatment in a case where no medical treatment was
needed for the injury or illness before the workplace event or exposure,
or a change in medical treatment was necessitated by the workplace event
or exposure.
(5) Which injuries and illnesses are considered pre-existing
conditions? An injury or illness is a preexisting condition if it
resulted solely from a non-work-related event or exposure that occured
outside the work environment.
(6) How do I decide whether an injury or illness is work-related if
the employee is on travel status at the time the injury or illness
occurs? Injuries and illnesses that occur while an employee is on travel
status are work-related if, at the time of the injury or illness, the
employee was engaged in work activities ``in the interest of the
employer.'' Examples of such activities include travel to and from
customer contacts, conducting job tasks, and entertaining or being
entertained to transact, discuss, or promote business (work-related
entertainment includes only entertainment activities being engaged in at
the direction of the employer).
Injuries or illnesses that occur when the employee is on travel
status do not have to be recorded if they meet one of the exceptions
listed below.
[[Page 48]]
----------------------------------------------------------------------------------------------------------------
You may use the following to
1904.5 (b)(6) If the employee has . . . determine if an injury or
illness is work-related
----------------------------------------------------------------------------------------------------------------
(i)..................... checked into a hotel or motel for one or more days.. When a traveling employee checks
into a hotel, motel, or into an
other temporary residence, he
or she establishes a ``home
away from home.'' You must
evaluate the employee's
activities after he or she
checks into the hotel, motel,
or other temporary residence
for their work-relatedness in
the same manner as you evaluate
the activities of a non-
traveling employee. When the
employee checks into the
temporary residence, he or she
is considered to have left the
work environment. When the
employee begins work each day,
he or she re-enters the work
environment. If the employee
has established a ``home away
from home'' and is reporting to
a fixed worksite each day, you
also do not consider injuries
or illnesses work-related if
they occur while the employee
is commuting between the
temporary residence and the job
location.
(ii).................... taken a detour for personal reasons................. Injuries or illnesses are not
considered work-related if they
occur while the employee is on
a personal detour from a
reasonably direct route of
travel (e.g., has taken a side
trip for personal reasons).
----------------------------------------------------------------------------------------------------------------
(7) How do I decide if a case is work-related when the employee is
working at home? Injuries and illnesses that occur while an employee is
working at home, including work in a home office, will be considered
work-related if the injury or illness occurs while the employee is
performing work for pay or compensation in the home, and the injury or
illness is directly related to the performance of work rather than to
the general home environment or setting. For example, if an employee
drops a box of work documents and injures his or her foot, the case is
considered work-related. If an employee's fingernail is punctured by a
needle from a sewing machine used to perform garment work at home,
becomes infected and requires medical treatment, the injury is
considered work-related. If an employee is injured because he or she
trips on the family dog while rushing to answer a work phone call, the
case is not considered work-related. If an employee working at home is
electrocuted because of faulty home wiring, the injury is not considered
work-related.
Sec. 1904.6 Determination of new cases.
(a) Basic requirement. You must consider an injury or illness to be
a ``new case'' if:
(1) The employee has not previously experienced a recorded injury or
illness of the same type that affects the same part of the body, or
(2) The employee previously experienced a recorded injury or illness
of the same type that affected the same part of the body but had
recovered completely (all signs and symptoms had disappeared) from the
previous injury or illness and an event or exposure in the work
environment caused the signs or symptoms to reappear.
(b) Implementation--(1) When an employee experiences the signs or
symptoms of a chronic work-related illness, do I need to consider each
recurrence of signs or symptoms to be a new case? No, for occupational
illnesses where the signs or symptoms may recur or continue in the
absence of an exposure in the workplace, the case must only be recorded
once. Examples may include occupational cancer, asbestosis, byssinosis
and silicosis.
(2) When an employee experiences the signs or symptoms of an injury
or illness as a result of an event or exposure in the workplace, such as
an episode of occupational asthma, must I treat the episode as a new
case? Yes, because the episode or recurrence was caused by an event or
exposure in the workplace, the incident must be treated as a new case.
(3) May I rely on a physician or other licensed health care
professional to determine whether a case is a new case or a recurrence
of an old case? You are not required to seek the advice of a physician
or other licensed health care professional. However, if you do seek such
advice, you must follow the physician or other licensed health care
professional's recommendation about whether the case is a new case or a
recurrence. If you receive recommendations from two or more physicians
or other
[[Page 49]]
licensed health care professionals, you must make a decision as to which
recommendation is the most authoritative (best documented, best
reasoned, or most authoritative), and record the case based upon that
recommendation.
Sec. 1904.7 General recording criteria.
(a) Basic requirement. You must consider an injury or illness to
meet the general recording criteria, and therefore to be recordable, if
it results in any of the following: death, days away from work,
restricted work or transfer to another job, medical treatment beyond
first aid, or loss of consciousness. You must also consider a case to
meet the general recording criteria if it involves a significant injury
or illness diagnosed by a physician or other licensed health care
professional, even if it does not result in death, days away from work,
restricted work or job transfer, medical treatment beyond first aid, or
loss of consciousness.
(b) Implementation--(1) How do I decide if a case meets one or more
of the general recording criteria? A work-related injury or illness must
be recorded if it results in one or more of the following:
(i) Death. See Sec. 1904.7(b)(2).
(ii) Days away from work. See Sec. 1904.7(b)(3).
(iii) Restricted work or transfer to another job. See Sec.
1904.7(b)(4).
(iv) Medical treatment beyond first aid. See Sec. 1904.7(b)(5).
(v) Loss of consciousness. See Sec. 1904.7(b)(6).
(vi) A significant injury or illness diagnosed by a physician or
other licensed health care professional. See Sec. 1904.7(b)(7).
(2) How do I record a work-related injury or illness that results in
the employee's death? You must record an injury or illness that results
in death by entering a check mark on the OSHA 300 Log in the space for
cases resulting in death. You must also report any work-related fatality
to OSHA within eight (8) hours, as required by Sec. 1904.39.
(3) How do I record a work-related injury or illness that results in
days away from work? When an injury or illness involves one or more days
away from work, you must record the injury or illness on the OSHA 300
Log with a check mark in the space for cases involving days away and an
entry of the number of calendar days away from work in the number of
days column. If the employee is out for an extended period of time, you
must enter an estimate of the days that the employee will be away, and
update the day count when the actual number of days is known.
(i) Do I count the day on which the injury occurred or the illness
began? No, you begin counting days away on the day after the injury
occurred or the illness began.
(ii) How do I record an injury or illness when a physician or other
licensed health care professional recommends that the worker stay at
home but the employee comes to work anyway? You must record these
injuries and illnesses on the OSHA 300 Log using the check box for cases
with days away from work and enter the number of calendar days away
recommended by the physician or other licensed health care professional.
If a physician or other licensed health care professional recommends
days away, you should encourage your employee to follow that
recommendation. However, the days away must be recorded whether the
injured or ill employee follows the physician or licensed health care
professional's recommendation or not. If you receive recommendations
from two or more physicians or other licensed health care professionals,
you may make a decision as to which recommendation is the most
authoritative, and record the case based upon that recommendation.
(iii) How do I handle a case when a physician or other licensed
health care professional recommends that the worker return to work but
the employee stays at home anyway? In this situation, you must end the
count of days away from work on the date the physician or other licensed
health care professional recommends that the employee return to work.
(iv) How do I count weekends, holidays, or other days the employee
would not have worked anyway? You must count the number of calendar days
the employee was unable to work as a result of the injury or illness,
regardless of whether or not the employee was scheduled to work on those
day(s). Weekend days, holidays, vacation days
[[Page 50]]
or other days off are included in the total number of days recorded if
the employee would not have been able to work on those days because of a
work-related injury or illness.
(v) How do I record a case in which a worker is injured or becomes
ill on a Friday and reports to work on a Monday, and was not scheduled
to work on the weekend? You need to record this case only if you receive
information from a physician or other licensed health care professional
indicating that the employee should not have worked, or should have
performed only restricted work, during the weekend. If so, you must
record the injury or illness as a case with days away from work or
restricted work, and enter the day counts, as appropriate.
(vi) How do I record a case in which a worker is injured or becomes
ill on the day before scheduled time off such as a holiday, a planned
vacation, or a temporary plant closing? You need to record a case of
this type only if you receive information from a physician or other
licensed health care professional indicating that the employee should
not have worked, or should have performed only restricted work, during
the scheduled time off. If so, you must record the injury or illness as
a case with days away from work or restricted work, and enter the day
counts, as appropriate.
(vii) Is there a limit to the number of days away from work I must
count? Yes, you may ``cap'' the total days away at 180 calendar days.
You are not required to keep track of the number of calendar days away
from work if the injury or illness resulted in more than 180 calendar
days away from work and/or days of job transfer or restriction. In such
a case, entering 180 in the total days away column will be considered
adequate.
(viii) May I stop counting days if an employee who is away from work
because of an injury or illness retires or leaves my company? Yes, if
the employee leaves your company for some reason unrelated to the injury
or illness, such as retirement, a plant closing, or to take another job,
you may stop counting days away from work or days of restriction/job
transfer. If the employee leaves your company because of the injury or
illness, you must estimate the total number of days away or days of
restriction/job transfer and enter the day count on the 300 Log.
(ix) If a case occurs in one year but results in days away during
the next calendar year, do I record the case in both years? No, you only
record the injury or illness once. You must enter the number of calendar
days away for the injury or illness on the OSHA 300 Log for the year in
which the injury or illness occurred. If the employee is still away from
work because of the injury or illness when you prepare the annual
summary, estimate the total number of calendar days you expect the
employee to be away from work, use this number to calculate the total
for the annual summary, and then update the initial log entry later when
the day count is known or reaches the 180-day cap.
(4) How do I record a work-related injury or illness that results in
restricted work or job transfer? When an injury or illness involves
restricted work or job transfer but does not involve death or days away
from work, you must record the injury or illness on the OSHA 300 Log by
placing a check mark in the space for job transfer or restriction and an
entry of the number of restricted or transferred days in the restricted
workdays column.
(i) How do I decide if the injury or illness resulted in restricted
work? Restricted work occurs when, as the result of a work-related
injury or illness:
(A) You keep the employee from performing one or more of the routine
functions of his or her job, or from working the full workday that he or
she would otherwise have been scheduled to work; or
(B) A physician or other licensed health care professional
recommends that the employee not perform one or more of the routine
functions of his or her job, or not work the full workday that he or she
would otherwise have been scheduled to work.
(ii) What is meant by ``routine functions''? For recordkeeping
purposes, an employee's routine functions are those work activities the
employee regularly performs at least once per week.
(iii) Do I have to record restricted work or job transfer if it
applies only to the day
[[Page 51]]
on which the injury occurred or the illness began? No, you do not have
to record restricted work or job transfers if you, or the physician or
other licensed health care professional, impose the restriction or
transfer only for the day on which the injury occurred or the illness
began.
(iv) If you or a physician or other licensed health care
professional recommends a work restriction, is the injury or illness
automatically recordable as a ``restricted work'' case? No, a
recommended work restriction is recordable only if it affects one or
more of the employee's routine job functions. To determine whether this
is the case, you must evaluate the restriction in light of the routine
functions of the injured or ill employee's job. If the restriction from
you or the physician or other licensed health care professional keeps
the employee from performing one or more of his or her routine job
functions, or from working the full workday the injured or ill employee
would otherwise have worked, the employee's work has been restricted and
you must record the case.
(v) How do I record a case where the worker works only for a partial
work shift because of a work-related injury or illness? A partial day of
work is recorded as a day of job transfer or restriction for
recordkeeping purposes, except for the day on which the injury occurred
or the illness began.
(vi) If the injured or ill worker produces fewer goods or services
than he or she would have produced prior to the injury or illness but
otherwise performs all of the routine functions of his or her work, is
the case considered a restricted work case? No, the case is considered
restricted work only if the worker does not perform all of the routine
functions of his or her job or does not work the full shift that he or
she would otherwise have worked.
(vii) How do I handle vague restrictions from a physician or other
licensed health care professional, such as that the employee engage only
in ``light duty'' or ``take it easy for a week''? If you are not clear
about the physician or other licensed health care professional's
recommendation, you may ask that person whether the employee can do all
of his or her routine job functions and work all of his or her normally
assigned work shift. If the answer to both of these questions is
``Yes,'' then the case does not involve a work restriction and does not
have to be recorded as such. If the answer to one or both of these
questions is ``No,'' the case involves restricted work and must be
recorded as a restricted work case. If you are unable to obtain this
additional information from the physician or other licensed health care
professional who recommended the restriction, record the injury or
illness as a case involving restricted work.
(viii) What do I do if a physician or other licensed health care
professional recommends a job restriction meeting OSHA's definition, but
the employee does all of his or her routine job functions anyway? You
must record the injury or illness on the OSHA 300 Log as a restricted
work case. If a physician or other licensed health care professional
recommends a job restriction, you should ensure that the employee
complies with that restriction. If you receive recommendations from two
or more physicians or other licensed health care professionals, you may
make a decision as to which recommendation is the most authoritative,
and record the case based upon that recommendation.
(ix) How do I decide if an injury or illness involved a transfer to
another job? If you assign an injured or ill employee to a job other
than his or her regular job for part of the day, the case involves
transfer to another job. Note: This does not include the day on which
the injury or illness occurred.
(x) Are transfers to another job recorded in the same way as
restricted work cases? Yes, both job transfer and restricted work cases
are recorded in the same box on the OSHA 300 Log. For example, if you
assign, or a physician or other licensed health care professional
recommends that you assign, an injured or ill worker to his or her
routine job duties for part of the day and to another job for the rest
of the day, the injury or illness involves a job transfer. You must
record an injury or illness that involves a job transfer by placing a
check in the box for job transfer.
(xi) How do I count days of job transfer or restriction? You count
days of job
[[Page 52]]
transfer or restriction in the same way you count days away from work,
using Sec. 1904.7(b)(3)(i) to (viii), above. The only difference is
that, if you permanently assign the injured or ill employee to a job
that has been modified or permanently changed in a manner that
eliminates the routine functions the employee was restricted from
performing, you may stop the day count when the modification or change
is made permanent. You must count at least one day of restricted work or
job transfer for such cases.
(5) How do I record an injury or illness that involves medical
treatment beyond first aid? If a work-related injury or illness results
in medical treatment beyond first aid, you must record it on the OSHA
300 Log. If the injury or illness did not involve death, one or more
days away from work, one or more days of restricted work, or one or more
days of job transfer, you enter a check mark in the box for cases where
the employee received medical treatment but remained at work and was not
transferred or restricted.
(i) What is the definition of medical treatment? ``Medical
treatment'' means the management and care of a patient to combat disease
or disorder. For the purposes of Part 1904, medical treatment does not
include:
(A) Visits to a physician or other licensed health care professional
solely for observation or counseling;
(B) The conduct of diagnostic procedures, such as x-rays and blood
tests, including the administration of prescription medications used
solely for diagnostic purposes (e.g., eye drops to dilate pupils); or
(C) ``First aid'' as defined in paragraph (b)(5)(ii) of this
section.
(ii) What is ``first aid''? For the purposes of Part 1904, ``first
aid'' means the following:
(A) Using a non-prescription medication at nonprescription strength
(for medications available in both prescription and non-prescription
form, a recommendation by a physician or other licensed health care
professional to use a non-prescription medication at prescription
strength is considered medical treatment for recordkeeping purposes);
(B) Administering tetanus immunizations (other immunizations, such
as Hepatitis B vaccine or rabies vaccine, are considered medical
treatment);
(C) Cleaning, flushing or soaking wounds on the surface of the skin;
(D) Using wound coverings such as bandages, Band-AidsTM,
gauze pads, etc.; or using butterfly bandages or Steri-
StripsTM (other wound closing devices such as sutures,
staples, etc., are considered medical treatment);
(E) Using hot or cold therapy;
(F) Using any non-rigid means of support, such as elastic bandages,
wraps, non-rigid back belts, etc. (devices with rigid stays or other
systems designed to immobilize parts of the body are considered medical
treatment for recordkeeping purposes);
(G) Using temporary immobilization devices while transporting an
accident victim (e.g., splints, slings, neck collars, back boards,
etc.).
(H) Drilling of a fingernail or toenail to relieve pressure, or
draining fluid from a blister;
(I) Using eye patches;
(J) Removing foreign bodies from the eye using only irrigation or a
cotton swab;
(K) Removing splinters or foreign material from areas other than the
eye by irrigation, tweezers, cotton swabs or other simple means;
(L) Using finger guards;
(M) Using massages (physical therapy or chiropractic treatment are
considered medical treatment for recordkeeping purposes); or
(N) Drinking fluids for relief of heat stress.
(iii) Are any other procedures included in first aid? No, this is a
complete list of all treatments considered first aid for Part 1904
purposes.
(iv) Does the professional status of the person providing the
treatment have any effect on what is considered first aid or medical
treatment? No, OSHA considers the treatments listed in Sec.
1904.7(b)(5)(ii) of this Part to be first aid regardless of the
professional status of the person providing the treatment. Even when
these treatments are provided by a physician or other licensed health
care professional, they are considered first
[[Page 53]]
aid for the purposes of Part 1904. Similarly, OSHA considers treatment
beyond first aid to be medical treatment even when it is provided by
someone other than a physician or other licensed health care
professional.
(v) What if a physician or other licensed health care professional
recommends medical treatment but the employee does not follow the
recommendation? If a physician or other licensed health care
professional recommends medical treatment, you should encourage the
injured or ill employee to follow that recommendation. However, you must
record the case even if the injured or ill employee does not follow the
physician or other licensed health care professional's recommendation.
(6) Is every work-related injury or illness case involving a loss of
consciousness recordable? Yes, you must record a work-related injury or
illness if the worker becomes unconscious, regardless of the length of
time the employee remains unconscious.
(7) What is a ``significant'' diagnosed injury or illness that is
recordable under the general criteria even if it does not result in
death, days away from work, restricted work or job transfer, medical
treatment beyond first aid, or loss of consciousness? Work-related cases
involving cancer, chronic irreversible disease, a fractured or cracked
bone, or a punctured eardrum must always be recorded under the general
criteria at the time of diagnosis by a physician or other licensed
health care professional.
Note to Sec. 1904.7: OSHA believes that most significant injuries
and illnesses will result in one of the criteria listed in Sec.
1904.7(a): death, days away from work, restricted work or job transfer,
medical treatment beyond first aid, or loss of consciousness. However,
there are some significant injuries, such as a punctured eardrum or a
fractured toe or rib, for which neither medical treatment nor work
restrictions may be recommended. In addition, there are some significant
progressive diseases, such as byssinosis, silicosis, and some types of
cancer, for which medical treatment or work restrictions may not be
recommended at the time of diagnosis but are likely to be recommended as
the disease progresses. OSHA believes that cancer, chronic irreversible
diseases, fractured or cracked bones, and punctured eardrums are
generally considered significant injuries and illnesses, and must be
recorded at the initial diagnosis even if medical treatment or work
restrictions are not recommended, or are postponed, in a particular
case.
Sec. 1904.8 Recording criteria for needlestick and sharps injuries.
(a) Basic requirement. You must record all work-related needlestick
injuries and cuts from sharp objects that are contaminated with another
person's blood or other potentially infectious material (as defined by
29 CFR 1910.1030). You must enter the case on the OSHA 300 Log as an
injury. To protect the employee's privacy, you may not enter the
employee's name on the OSHA 300 Log (see the requirements for privacy
cases in paragraphs 1904.29(b)(6) through 1904.29(b)(9)).
(b) Implementation--(1) What does ``other potentially infectious
material'' mean? The term ``other potentially infectious materials'' is
defined in the OSHA Bloodborne Pathogens standard at Sec. 1910.1030(b).
These materials include:
(i) Human bodily fluids, tissues and organs, and
(ii) Other materials infected with the HIV or hepatitis B (HBV)
virus such as laboratory cultures or tissues from experimental animals.
(2) Does this mean that I must record all cuts, lacerations,
punctures, and scratches? No, you need to record cuts, lacerations,
punctures, and scratches only if they are work-related and involve
contamination with another person's blood or other potentially
infectious material. If the cut, laceration, or scratch involves a clean
object, or a contaminant other than blood or other potentially
infectious material, you need to record the case only if it meets one or
more of the recording criteria in Sec. 1904.7.
(3) If I record an injury and the employee is later diagnosed with
an infectious bloodborne disease, do I need to update the OSHA 300 Log?
Yes, you must update the classification of the case on the OSHA 300 Log
if the case results in death, days away from work, restricted work, or
job transfer. You must also update the description to identify the
infectious disease and change the classification of the case from an
injury to an illness.
[[Page 54]]
(4) What if one of my employees is splashed or exposed to blood or
other potentially infectious material without being cut or scratched? Do
I need to record this incident? You need to record such an incident on
the OSHA 300 Log as an illness if:
(i) It results in the diagnosis of a bloodborne illness, such as
HIV, hepatitis B, or hepatitis C; or
(ii) It meets one or more of the recording criteria in Sec. 1904.7.
Sec. 1904.9 Recording criteria for cases involving medical removal
under OSHA standards.
(a) Basic requirement. If an employee is medically removed under the
medical surveillance requirements of an OSHA standard, you must record
the case on the OSHA 300 Log.
(b) Implementation--(1) How do I classify medical removal cases on
the OSHA 300 Log? You must enter each medical removal case on the OSHA
300 Log as either a case involving days away from work or a case
involving restricted work activity, depending on how you decide to
comply with the medical removal requirement. If the medical removal is
the result of a chemical exposure, you must enter the case on the OSHA
300 Log by checking the ``poisoning'' column.
(2) Do all of OSHA's standards have medical removal provisions? No,
some OSHA standards, such as the standards covering bloodborne pathogens
and noise, do not have medical removal provisions. Many OSHA standards
that cover specific chemical substances have medical removal provisions.
These standards include, but are not limited to, lead, cadmium,
methylene chloride, formaldehyde, and benzene.
(3) Do I have to record a case where I voluntarily removed the
employee from exposure before the medical removal criteria in an OSHA
standard are met? No, if the case involves voluntary medical removal
before the medical removal levels required by an OSHA standard, you do
not need to record the case on the OSHA 300 Log.
Sec. 1904.10 Recording criteria for cases involving occupational
hearing loss.
(a) Basic requirement. If an employee's hearing test (audiogram)
reveals that the employee has experienced a work-related Standard
Threshold Shift (STS) in hearing in one or both ears, and the employee's
total hearing level is 25 decibels (dB) or more above audiometric zero
(averaged at 2000, 3000, and 4000 Hz) in the same ear(s) as the STS, you
must record the case on the OSHA 300 Log.
(b) Implementation--(1) What is a Standard Threshold Shift? A
Standard Threshold Shift, or STS, is defined in the occupational noise
exposure standard at 29 CFR 1910.95(g)(10)(i) as a change in hearing
threshold, relative to the baseline audiogram for that employee, of an
average of 10 decibels (dB) or more at 2000, 3000, and 4000 hertz (Hz)
in one or both ears.
(2) How do I evaluate the current audiogram to determine whether an
employee has an STS and a 25-dB hearing level?--(i) STS. If the employee
has never previously experienced a recordable hearing loss, you must
compare the employee's current audiogram with that employee's baseline
audiogram. If the employee has previously experienced a recordable
hearing loss, you must compare the employee's current audiogram with the
employee's revised baseline audiogram (the audiogram reflecting the
employee's previous recordable hearing loss case).
(ii) 25-dB loss. Audiometric test results reflect the employee's
overall hearing ability in comparison to audiometric zero. Therefore,
using the employee's current audiogram, you must use the average hearing
level at 2000, 3000, and 4000 Hz to determine whether or not the
employee's total hearing level is 25 dB or more.
(3) May I adjust the current audiogram to reflect the effects of
aging on hearing? Yes. When you are determining whether an STS has
occurred, you may age adjust the employee's current audiogram results by
using Tables F-1 or F-2, as appropriate, in Appendix F of 29 CFR
1910.95. You may not use an age adjustment when determining whether the
employee's total hearing level is 25 dB or more above audiometric zero.
(4) Do I have to record the hearing loss if I am going to retest the
employee's hearing? No, if you retest the employee's hearing within 30
days of the first test, and the retest does not confirm
[[Page 55]]
the recordable STS, you are not required to record the hearing loss case
on the OSHA 300 Log. If the retest confirms the recordable STS, you must
record the hearing loss illness within seven (7) calendar days of the
retest. If subsequent audiometric testing performed under the testing
requirements of the Sec. 1910.95 noise standard indicates that an STS
is not persistent, you may erase or line-out the recorded entry.
(5) Are there any special rules for determining whether a hearing
loss case is work-related? No. You must use the rules in Sec. 1904.5 to
determine if the hearing loss is work-related. If an event or exposure
in the work environment either caused or contributed to the hearing
loss, or significantly aggravated a pre-existing hearing loss, you must
consider the case to be work related.
(6) If a physician or other licensed health care professional
determines the hearing loss is not work-related, do I still need to
record the case?
If a physician or other licensed health care professional determines
that the hearing loss is not work-related or has not been significantly
aggravated by occupational noise exposure, you are not required to
consider the case work-related or to record the case on the OSHA 300
Log.
(7) How do I complete the 300 Log for a hearing loss case? When you
enter a recordable hearing loss case on the OSHA 300 Log, you must check
the 300 Log column for hearing loss.
(Note: Sec. 1904.10(b)(7) is effective beginning January 1, 2004.)
[67 FR 44047, July 1, 2002, as amended at 67 FR 77170, Dec. 17, 2002]
Sec. 1904.11 Recording criteria for work-related tuberculosis cases.
(a) Basic requirement. If any of your employees has been
occupationally exposed to anyone with a known case of active
tuberculosis (TB), and that employee subsequently develops a
tuberculosis infection, as evidenced by a positive skin test or
diagnosis by a physician or other licensed health care professional, you
must record the case on the OSHA 300 Log by checking the ``respiratory
condition'' column.
(b) Implementation--(1) Do I have to record, on the Log, a positive
TB skin test result obtained at a pre-employment physical? No, you do
not have to record it because the employee was not occupationally
exposed to a known case of active tuberculosis in your workplace.
(2) May I line-out or erase a recorded TB case if I obtain evidence
that the case was not caused by occupational exposure? Yes, you may
line-out or erase the case from the Log under the following
circumstances:
(i) The worker is living in a household with a person who has been
diagnosed with active TB;
(ii) The Public Health Department has identified the worker as a
contact of an individual with a case of active TB unrelated to the
workplace; or
(iii) A medical investigation shows that the employee's infection
was caused by exposure to TB away from work, or proves that the case was
not related to the workplace TB exposure.
Sec. Sec. 1904.13-1904.28 [Reserved]
Sec. 1904.29 Forms.
(a) Basic requirement. You must use OSHA 300, 300-A, and 301 forms,
or equivalent forms, for recordable injuries and illnesses. The OSHA 300
form is called the Log of Work-Related Injuries and Illnesses, the 300-A
is the Summary of Work-Related Injuries and Illnesses, and the OSHA 301
form is called the Injury and Illness Incident Report.
(b) Implementation--(1) What do I need to do to complete the OSHA
300 Log? You must enter information about your business at the top of
the OSHA 300 Log, enter a one or two line description for each
recordable injury or illness, and summarize this information on the OSHA
300-A at the end of the year.
(2) What do I need to do to complete the OSHA 301 Incident Report?
You must complete an OSHA 301 Incident Report form, or an equivalent
form, for each recordable injury or illness entered on the OSHA 300 Log.
(3) How quickly must each injury or illness be recorded? You must
enter each recordable injury or illness on the OSHA 300 Log and 301
Incident Report within seven (7) calendar days of receiving information
that a recordable injury or illness has occurred.
[[Page 56]]
(4) What is an equivalent form? An equivalent form is one that has
the same information, is as readable and understandable, and is
completed using the same instructions as the OSHA form it replaces. Many
employers use an insurance form instead of the OSHA 301 Incident Report,
or supplement an insurance form by adding any additional information
required by OSHA.
(5) May I keep my records on a computer? Yes, if the computer can
produce equivalent forms when they are needed, as described under
Sec. Sec. 1904.35 and 1904.40, you may keep your records using the
computer system.
(6) Are there situations where I do not put the employee's name on
the forms for privacy reasons? Yes, if you have a ``privacy concern
case,'' you may not enter the employee's name on the OSHA 300 Log.
Instead, enter ``privacy case'' in the space normally used for the
employee's name. This will protect the privacy of the injured or ill
employee when another employee, a former employee, or an authorized
employee representative is provided access to the OSHA 300 Log under
Sec. 1904.35(b)(2). You must keep a separate, confidential list of the
case numbers and employee names for your privacy concern cases so you
can update the cases and provide the information to the government if
asked to do so.
(7) How do I determine if an injury or illness is a privacy concern
case? You must consider the following injuries or illnesses to be
privacy concern cases:
(i) An injury or illness to an intimate body part or the
reproductive system;
(ii) An injury or illness resulting from a sexual assault;
(iii) Mental illnesses;
(iv) HIV infection, hepatitis, or tuberculosis;
(v) Needlestick injuries and cuts from sharp objects that are
contaminated with another person's blood or other potentially infectious
material (see Sec. 1904.8 for definitions); and
(vi) Other illnesses, if the employee voluntarily requests that his
or her name not be entered on the log.
(8) May I classify any other types of injuries and illnesses as
privacy concern cases? No, this is a complete list of all injuries and
illnesses considered privacy concern cases for Part 1904 purposes.
(9) If I have removed the employee's name, but still believe that
the employee may be identified from the information on the forms, is
there anything else that I can do to further protect the employee's
privacy? Yes, if you have a reasonable basis to believe that information
describing the privacy concern case may be personally identifiable even
though the employee's name has been omitted, you may use discretion in
describing the injury or illness on both the OSHA 300 and 301 forms. You
must enter enough information to identify the cause of the incident and
the general severity of the injury or illness, but you do not need to
include details of an intimate or private nature. For example, a sexual
assault case could be described as ``injury from assault,'' or an injury
to a reproductive organ could be described as ``lower abdominal
injury.''
(10) What must I do to protect employee privacy if I wish to provide
access to the OSHA Forms 300 and 301 to persons other than government
representatives, employees, former employees or authorized
representatives? If you decide to voluntarily disclose the Forms to
persons other than government representatives, employees, former
employees or authorized representatives (as required by Sec. Sec.
1904.35 and 1904.40), you must remove or hide the employees' names and
other personally identifying information, except for the following
cases. You may disclose the Forms with personally identifying
information only:
(i) to an auditor or consultant hired by the employer to evaluate
the safety and health program;
(ii) to the extent necessary for processing a claim for workers'
compensation or other insurance benefits; or
(iii) to a public health authority or law enforcement agency for
uses and disclosures for which consent, an authorization, or opportunity
to agree or object is not required under Department of Health and Human
Services Standards for Privacy of Individually Identifiable Health
Information, 45 CFR 164.512.
[66 FR 6122, Jan. 19, 2001, as amended at 66 FR 52034, Oct. 12, 2001; 67
FR 77170, Dec. 17, 2002; 68 FR 38607, June 30, 2003]

Subpart D_Other OSHA Injury and Illness Recordkeeping Requirements
Sec. 1904.30 Multiple business establishments.
(a) Basic requirement. You must keep a separate OSHA 300 Log for
each establishment that is expected to be in operation for one year or
longer.
(b) Implementation--(1) Do I need to keep OSHA injury and illness
records for short-term establishments (i.e., establishments that will
exist for less than a year)? Yes, however, you do not have to keep a
separate OSHA 300 Log for each such establishment. You may keep one OSHA
300 Log that covers all of your short-term establishments. You may also
include the short-term establishments' recordable injuries and illnesses
on an OSHA 300 Log that covers short-term establishments for individual
company divisions or geographic regions.
(2) May I keep the records for all of my establishments at my
headquarters location or at some other central location? Yes, you may
keep the records for an establishment at your headquarters or other
central location if you can:
(i) Transmit information about the injuries and illnesses from the
establishment to the central location within seven (7) calendar days of
receiving information that a recordable injury or illness has occurred;
and
(ii) Produce and send the records from the central location to the
establishment within the time frames required by Sec. 1904.35 and Sec.
1904.40 when you are required to provide records to a government
representative, employees, former employees or employee representatives.
(3) Some of my employees work at several different locations or do
not work at any of my establishments at all. How do I record cases for
these employees? You must link each of your employees with one of your
establishments, for recordkeeping purposes. You must record the injury
and illness on the OSHA 300 Log of the injured or ill employee's
establishment, or on an OSHA 300 Log that covers that employee's short-
term establishment.
(4) How do I record an injury or illness when an employee of one of
my establishments is injured or becomes ill while visiting or working at
another of my establishments, or while working away from any of my
establishments? If the injury or illness occurs at one of your
establishments, you must record the injury or illness on the OSHA 300
Log of the establishment at which the injury or illness occurred. If the
employee is injured or becomes ill and is not at one of your
establishments, you must record the case on the OSHA 300 Log at the
establishment at which the employee normally works.
Sec. 1904.31 Covered employees.
(a) Basic requirement. You must record on the OSHA 300 Log the
recordable injuries and illnesses of all employees on your payroll,
whether they are labor, executive, hourly, salary, part-time, seasonal,
or migrant workers. You also must record the recordable injuries and
illnesses that occur to employees who are not on your payroll if you
supervise these employees on a day-to-day basis. If your business is
organized as a sole proprietorship or partnership, the owner or partners
are not considered employees for recordkeeping purposes.
(b) Implementation--(1) If a self-employed person is injured or
becomes ill while doing work at my business, do I need to record the
injury or illness? No, self-employed individuals are not covered by the
OSH Act or this regulation.
(2) If I obtain employees from a temporary help service, employee
leasing service, or personnel supply service, do I have to record an
injury or illness occurring to one of those employees? You must record
these injuries and illnesses if you supervise these employees on a day-
to-day basis.
(3) If an employee in my establishment is a contractor's employee,
must I record an injury or illness occurring to that employee? If the
contractor's employee is under the day-to-day supervision of the
contractor, the contractor is responsible for recording the injury or
illness. If you supervise the contractor employee's work on a day-to-day
basis, you must record the injury or illness.
(4) Must the personnel supply service, temporary help service,
employee leasing service, or contractor also record the injuries or
illnesses occurring to temporary,
[[Page 58]]
leased or contract employees that I supervise on a day-to-day basis? No,
you and the temporary help service, employee leasing service, personnel
supply service, or contractor should coordinate your efforts to make
sure that each injury and illness is recorded only once: either on your
OSHA 300 Log (if you provide day-to-day supervision) or on the other
employer's OSHA 300 Log (if that company provides day-to-day
supervision).
Sec. 1904.32 Annual summary.
(a) Basic requirement. At the end of each calendar year, you must:
(1) Review the OSHA 300 Log to verify that the entries are complete
and accurate, and correct any deficiencies identified;
(2) Create an annual summary of injuries and illnesses recorded on
the OSHA 300 Log;
(3) Certify the summary; and
(4) Post the annual summary.
(b) Implementation--(1) How extensively do I have to review the OSHA
300 Log entries at the end of the year? You must review the entries as
extensively as necessary to make sure that they are complete and
correct.
(2) How do I complete the annual summary? You must:
(i) Total the columns on the OSHA 300 Log (if you had no recordable
cases, enter zeros for each column total); and
(ii) Enter the calendar year covered, the company's name,
establishment name, establishment address, annual average number of
employees covered by the OSHA 300 Log, and the total hours worked by all
employees covered by the OSHA 300 Log.
(iii) If you are using an equivalent form other than the OSHA 300-A
summary form, as permitted under Sec. 1904.6(b)(4), the summary you use
must also include the employee access and employer penalty statements
found on the OSHA 300-A Summary form.
(3) How do I certify the annual summary? A company executive must
certify that he or she has examined the OSHA 300 Log and that he or she
reasonably believes, based on his or her knowledge of the process by
which the information was recorded, that the annual summary is correct
and complete.
(4) Who is considered a company executive? The company executive who
certifies the log must be one of the following persons:
(i) An owner of the company (only if the company is a sole
proprietorship or partnership);
(ii) An officer of the corporation;
(iii) The highest ranking company official working at the
establishment; or
(iv) The immediate supervisor of the highest ranking company
official working at the establishment.
(5) How do I post the annual summary? You must post a copy of the
annual summary in each establishment in a conspicuous place or places
where notices to employees are customarily posted. You must ensure that
the posted annual summary is not altered, defaced or covered by other
material.
(6) When do I have to post the annual summary? You must post the
summary no later than February 1 of the year following the year covered
by the records and keep the posting in place until April 30.
Sec. 1904.33 Retention and updating.
(a) Basic requirement. You must save the OSHA 300 Log, the privacy
case list (if one exists), the annual summary, and the OSHA 301 Incident
Report forms for five (5) years following the end of the calendar year
that these records cover.
(b) Implementation--(1) Do I have to update the OSHA 300 Log during
the five-year storage period? Yes, during the storage period, you must
update your stored OSHA 300 Logs to include newly discovered recordable
injuries or illnesses and to show any changes that have occurred in the
classification of previously recorded injuries and illnesses. If the
description or outcome of a case changes, you must remove or line out
the original entry and enter the new information.
(2) Do I have to update the annual summary? No, you are not required
to update the annual summary, but you may do so if you wish.
(3) Do I have to update the OSHA 301 Incident Reports? No, you are
not required to update the OSHA 301 Incident Reports, but you may do so
if you wish.
[[Page 59]]
Sec. 1904.34 Change in business ownership.
If your business changes ownership, you are responsible for
recording and reporting work-related injuries and illnesses only for
that period of the year during which you owned the establishment. You
must transfer the Part 1904 records to the new owner. The new owner must
save all records of the establishment kept by the prior owner, as
required by Sec. 1904.33 of this Part, but need not update or correct
the records of the prior owner.
Sec. 1904.35 Employee involvement.
(a) Basic requirement. Your employees and their representatives must
be involved in the recordkeeping system in several ways.
(1) You must inform each employee of how he or she is to report an
injury or illness to you.
(2) You must provide limited access to your injury and illness
records for your employees and their representatives.
(b) Implementation--(1) What must I do to make sure that employees
report work-related injuries and illnesses to me? (i) You must set up a
way for employees to report work-related injuries and illnesses
promptly; and
(ii) You must tell each employee how to report work-related injuries
and illnesses to you.
(2) Do I have to give my employees and their representatives access
to the OSHA injury and illness records? Yes, your employees, former
employees, their personal representatives, and their authorized employee
representatives have the right to access the OSHA injury and illness
records, with some limitations, as discussed below.
(i) Who is an authorized employee representative? An authorized
employee representative is an authorized collective bargaining agent of
employees.
(ii) Who is a ``personal representative'' of an employee or former
employee? A personal representative is:
(A) Any person that the employee or former employee designates as
such, in writing; or
(B) The legal representative of a deceased or legally incapacitated
employee or former employee.
(iii) If an employee or representative asks for access to the OSHA
300 Log, when do I have to provide it? When an employee, former
employee, personal representative, or authorized employee representative
asks for copies of your current or stored OSHA 300 Log(s) for an
establishment the employee or former employee has worked in, you must
give the requester a copy of the relevant OSHA 300 Log(s) by the end of
the next business day.
(iv) May I remove the names of the employees or any other
information from the OSHA 300 Log before I give copies to an employee,
former employee, or employee representative? No, you must leave the
names on the 300 Log. However, to protect the privacy of injured and ill
employees, you may not record the employee's name on the OSHA 300 Log
for certain ``privacy concern cases,'' as specified in paragraphs
1904.29(b)(6) through 1904.29(b)(9).
(v) If an employee or representative asks for access to the OSHA 301
Incident Report, when do I have to provide it? (A) When an employee,
former employee, or personal representative asks for a copy of the OSHA
301 Incident Report describing an injury or illness to that employee or
former employee, you must give the requester a copy of the OSHA 301
Incident Report containing that information by the end of the next
business day.
(B) When an authorized employee representative asks for a copies of
the OSHA 301 Incident Reports for an establishment where the agent
represents employees under a collective bargaining agreement, you must
give copies of those forms to the authorized employee representative
within 7 calendar days. You are only required to give the authorized
employee representative information from the OSHA 301 Incident Report
section titled ``Tell us about the case.'' You must remove all other
information from the copy of the OSHA 301 Incident Report or the
equivalent substitute form that you give to the authorized employee
representative.
(vi) May I charge for the copies? No, you may not charge for these
copies the first time they are provided. However, if one of the
designated persons
[[Page 60]]
asks for additional copies, you may assess a reasonable charge for
retrieving and copying the records.
Sec. 1904.36 Prohibition against discrimination.
Section 11(c) of the Act prohibits you from discriminating against
an employee for reporting a work-related fatality, injury or illness.
That provision of the Act also protects the employee who files a safety
and health complaint, asks for access to the Part 1904 records, or
otherwise exercises any rights afforded by the OSH Act.
Sec. 1904.37 State recordkeeping regulations.
(a) Basic requirement. Some States operate their own OSHA programs,
under the authority of a State Plan approved by OSHA. States operating
OSHA-approved State Plans must have occupational injury and illness
recording and reporting requirements that are substantially identical to
the requirements in this Part (see 29 CFR 1902.3(k), 29 CFR 1952.4 and
29 CFR 1956.10(i)).
(b) Implementation. (1) State-Plan States must have the same
requirements as Federal OSHA for determining which injuries and
illnesses are recordable and how they are recorded.
(2) For other Part 1904 provisions (for example, industry
exemptions, reporting of fatalities and hospitalizations, record
retention, or employee involvement), State-Plan State requirements may
be more stringent than or supplemental to the Federal requirements, but
because of the unique nature of the national recordkeeping program,
States must consult with and obtain approval of any such requirements.
(3) Although State and local government employees are not covered
Federally, all State-Plan States must provide coverage, and must develop
injury and illness statistics, for these workers. State Plan recording
and reporting requirements for State and local government entities may
differ from those for the private sector but must meet the requirements
of paragraphs 1904.37(b)(1) and (b)(2).
(4) A State-Plan State may not issue a variance to a private sector
employer and must recognize all variances issued by Federal OSHA.
(5) A State Plan State may only grant an injury and illness
recording and reporting variance to a State or local government employer
within the State after obtaining approval to grant the variance from
Federal OSHA.
Sec. 1904.38 Variances from the recordkeeping rule.
(a) Basic requirement. If you wish to keep records in a different
manner from the manner prescribed by the Part 1904 regulations, you may
submit a variance petition to the Assistant Secretary of Labor for
Occupational Safety and Health, U.S. Department of Labor, Washington, DC
20210. You can obtain a variance only if you can show that your
alternative recordkeeping system:
(1) Collects the same information as this Part requires;
(2) Meets the purposes of the Act; and
(3) Does not interfere with the administration of the Act.
(b) Implementation--(1) What do I need to include in my variance
petition? You must include the following items in your petition:
(i) Your name and address;
(ii) A list of the State(s) where the variance would be used;
(iii) The address(es) of the business establishment(s) involved;
(iv) A description of why you are seeking a variance;
(v) A description of the different recordkeeping procedures you
propose to use;
(vi) A description of how your proposed procedures will collect the
same information as would be collected by this Part and achieve the
purpose of the Act; and
(vii) A statement that you have informed your employees of the
petition by giving them or their authorized representative a copy of the
petition and by posting a statement summarizing the petition in the same
way as notices are posted under Sec. 1903.2(a).
(2) How will the Assistant Secretary handle my variance petition?
The Assistant Secretary will take the following steps to process your
variance petition.
(i) The Assistant Secretary will offer your employees and their
authorized
[[Page 61]]
representatives an opportunity to submit written data, views, and
arguments about your variance petition.
(ii) The Assistant Secretary may allow the public to comment on your
variance petition by publishing the petition in the Federal Register. If
the petition is published, the notice will establish a public comment
period and may include a schedule for a public meeting on the petition.
(iii) After reviewing your variance petition and any comments from
your employees and the public, the Assistant Secretary will decide
whether or not your proposed recordkeeping procedures will meet the
purposes of the Act, will not otherwise interfere with the Act, and will
provide the same information as the Part 1904 regulations provide. If
your procedures meet these criteria, the Assistant Secretary may grant
the variance subject to such conditions as he or she finds appropriate.
(iv) If the Assistant Secretary grants your variance petition, OSHA
will publish a notice in the Federal Register to announce the variance.
The notice will include the practices the variance allows you to use,
any conditions that apply, and the reasons for allowing the variance.
(3) If I apply for a variance, may I use my proposed recordkeeping
procedures while the Assistant Secretary is processing the variance
petition? No, alternative recordkeeping practices are only allowed after
the variance is approved. You must comply with the Part 1904 regulations
while the Assistant Secretary is reviewing your variance petition.
(4) If I have already been cited by OSHA for not following the Part
1904 regulations, will my variance petition have any effect on the
citation and penalty? No, in addition, the Assistant Secretary may elect
not to review your variance petition if it includes an element for which
you have been cited and the citation is still under review by a court,
an Administrative Law Judge (ALJ), or the OSH Review Commission.
(5) If I receive a variance, may the Assistant Secretary revoke the
variance at a later date? Yes, the Assistant Secretary may revoke your
variance if he or she has good cause. The procedures revoking a variance
will follow the same process as OSHA uses for reviewing variance
petitions, as outlined in paragraph 1904.38(b)(2). Except in cases of
willfulness or where necessary for public safety, the Assistant
Secretary will:
(i) Notify you in writing of the facts or conduct that may warrant
revocation of your variance; and
(ii) Provide you, your employees, and authorized employee
representatives with an opportunity to participate in the revocation
procedures.
Subpart E_Reporting Fatality, Injury and Illness Information to the
Government
Sec. 1904.39 Reporting fatalities and multiple hospitalization
incidents to OSHA.
(a) Basic requirement. Within eight (8) hours after the death of any
employee from a work-related incident or the in-patient hospitalization
of three or more employees as a result of a work-related incident, you
must orally report the fatality/multiple hospitalization by telephone or
in person to the Area Office of the Occupational Safety and Health
Administration (OSHA), U.S. Department of Labor, that is nearest to the
site of the incident. You may also use the OSHA toll-free central
telephone number, 1-800-321-OSHA (1-800-321-6742).

Subpart G_Definitions
Sec. 1904.46 Definitions.
The Act. The Act means the Occupational Safety and Health Act of
1970 (29 U.S.C. 651 et seq.). The definitions contained in section 3 of
the Act (29 U.S.C. 652) and related interpretations apply to such terms
when used in this Part 1904.
Establishment. An establishment is a single physical location where
business is conducted or where services or industrial operations are
performed. For activities where employees do not work at a single
physical location, such as construction; transportation; communications,
electric, gas and sanitary services; and similar operations, the
establishment is represented by main or branch offices, terminals,
stations, etc. that either supervise such activities or are the base
from which personnel carry out these activities.
(1) Can one business location include two or more establishments?
Normally, one business location has only one establishment. Under
limited conditions, the employer may consider two or more separate
businesses that share a single location to be separate establishments.
An employer may divide one location into two or more establishments only
when:
(i) Each of the establishments represents a distinctly separate
business;
(ii) Each business is engaged in a different economic activity;
(iii) No one industry description in the Standard Industrial
Classification Manual (1987) applies to the joint activities of the
establishments; and
(iv) Separate reports are routinely prepared for each establishment
on the number of employees, their wages and salaries, sales or receipts,
and other business information. For example, if an employer operates a
construction company at the same location as a lumber yard, the employer
may consider each business to be a separate establishment.
(2) Can an establishment include more than one physical location?
Yes, but only under certain conditions. An employer may combine two or
more physical locations into a single establishment only when:
(i) The employer operates the locations as a single business
operation under common management;
(ii) The locations are all located in close proximity to each other;
and
(iii) The employer keeps one set of business records for the
locations, such as records on the number of employees, their wages and
salaries, sales or receipts, and other kinds of business information.
For example, one manufacturing establishment might include the main
plant, a warehouse a few blocks away, and an administrative services
building across the street.
(3) If an employee telecommutes from home, is his or her home
considered a separate establishment? No, for employees who telecommute
from home, the employee's home is not a business establishment and a
separate 300 Log is not required. Employees who telecommute must be
linked to one of your establishments under Sec. 1904.30(b)(3).
Injury or illness. An injury or illness is an abnormal condition or
disorder. Injuries include cases such as, but not limited to, a cut,
fracture, sprain, or amputation. Illnesses include both acute and
chronic illnesses, such as,
[[Page 65]]
but not limited to, a skin disease, respiratory disorder, or poisoning.
(Note: Injuries and illnesses are recordable only if they are new, work-
related cases that meet one or more of the Part 1904 recording
criteria.)
Physician or Other Licensed Health Care Professional. A physician or
other licensed health care professional is an individual whose legally
permitted scope of practice (i.e., license, registration, or
certification) allows him or her to independently perform, or be
delegated the responsibility to perform, the activities described by
this regulation.
You. ``You'' means an employer as defined in Section 3 of the
Occupational Safety and Health Act of 1970 (29 U.S.C. 652).

read to the witness, subscribed by him, and certified by the officer
before whom the deposition is taken. Thereafter, the officer shall seal
the deposition, with two copies thereof, in an envelope and mail the
same by registered mail to the presiding hearing examiner. Subject to
such objections to the questions and answers as were noted at the time
of taking the deposition and would be valid were the witness personally
present and testifying, such deposition may be read and offered in
evidence by the party taking it as against any party who was present,
represented at the taking of the deposition, or who had due notice
thereof. No part of a deposition shall be admitted in evidence unless
there is a showing that the reasons for the taking of the deposition in
the first instance exist at the time of hearing.
(b) Other discovery. Whenever appropriate to a just disposition of
any issue in a hearing, the presiding hearing examiner may allow
discovery by any other appropriate procedure, such as by written

documentary evidence may be received, but a presiding hearing examiner
shall exclude evidence which is irrelevant, immaterial, or unduly
repetitious.
(2) Testimony of witnesses. The testimony of a witness shall be upon
oath or affirmation administered by the presiding hearing examiner.
(3) Objections. If a party objects to the admission or rejection of
any evidence, or to the limitation of the scope of any examination or
cross-examination, or to the failure to limit such scope, he shall state

appear in the record. Only objections made before the presiding hearing
examiner may be relied upon subsequently in a proceeding.
(4) Exceptions. Formal exception to an adverse ruling is not
required.

final upon the 20th day after service thereof, unless exceptions are
filed thereto, as provided in Sec. 1905.28. The decision of the hearing
examiner shall include (1) a statement of findings and conclusions, with
reasons and bases therefor, upon each material issue of fact, law, or
discretion presented on the record, and (2) the appropriate rule, order,
relief, or denial thereof. The decision of the hearing examiner shall be
based upon a consideration of the whole record and shall state all facts
officially noticed and relied upon. It shall be made on the basis of a
preponderance of reliable and probative evidence.
Sec. 1905.28 Exceptions.
Within 20 days after service of a decision of a presiding hearing
examiner, any party may file with the hearing examiner written
exceptions thereto with supporting reasons. Such exceptions shall refer
to the specific findings of fact, conclusions of law, or terms of the
rule or order excepted to, the specific pages of transcript relevant to
the suggestions, and shall suggest corrected findings of fact,

Sec. 1905.30 Decision of the Assistant Secretary.
If exceptions to a decision of a hearing examiner are taken pursuant
to Sec. 1905.28, the Assistant Secretary shall upon consideration
thereof, together with the record references and authorities cited in
support thereof, and any objections to exceptions and supporting
reasons, make his decision. The decision may affirm, modify, or set
aside, in whole or part, the findings, conclusions, and the rule or
order contained in the decision of the presiding hearing examiner, and
shall include a statement of reasons or bases for the actions taken on
each exception presented.
Subpart D_Summary Decisions
Sec. 1905.40 Motion for summary decision.
(a) Any party may, at least 20 days before the date fixed for any
hearing under subpart C of this part, move with
[[Page 75]]
or without supporting affidavits for a summary decision in his favor on
all or any part of the proceeding. Any other party may, within 10 days
after service of the motion, serve opposing affidavits or countermove
for summary decision. The presiding hearing examiner may, in his
discretion, set the matter for argument and call for the submission of
briefs.
(b) The filing of any documents under paragraph (a) of this section
shall be with the hearing examiner, and copies of any such documents
shall be served in accordance with Sec. 1905.21.
(c) The hearing examiner may grant such motion if the pleadings,
affidavits, material obtained by discovery or otherwise obtained, or
matters officially noticed show that there is no genuine issue as to any
material fact and that a party is entitled to summary decision. The
hearing examiner may deny such motion whenever the moving party denies
access to information by means of discovery to a party opposing the
motion.
(d) Affidavits shall set forth such facts as would be admissible in
evidence in a proceeding subject to 5 U.S.C. 556 and 557 and shall show
affirmatively that the affiant is competent to testify to the matters
stated therein. When a motion for summary decision is made and supported
as provided in this section, a party opposing the motion may not rest
upon the mere allegations or denials of his pleading; his response must
set forth specific facts showing that there is a genuine issue of fact
for the hearing.
(e) Should it appear from the affidavits of a party opposing the
motion that he cannot for reasons stated present by affidavit facts
essential to justify his opposition, the hearing examiner may deny the
motion for summary decision or may order a continuance to permit
affidavits to be obtained or discovery to be had or may make such other
order as is just.
(f) The denial of all or any part of a motion for summary decision
by the hearing examiner shall not be subject to interlocutory appeal to
the Assistant Secretary unless the hearing examiner certifies in writing
(1) that the ruling involves an important question of law or policy as
to which there is substantial ground for difference of opinion, and (2)
that an immediate appeal from the ruling may materially advance the
ultimate termination of the proceeding. The allowance of such an
interlocutory appeal shall not stay the proceeding before the hearing
examiner unless the Assistant Secretary shall so order.
Sec. 1905.41 Summary decision.
(a) No genuine issue of material fact. (1) Where no genuine issue of
a material fact is found to have been raised, the hearing examiner may
issue an initial decision to become final 20 days after service thereof,
unless, within such period of time any party has filed written
exceptions to the decision. If any timely exception is filed, the
hearing examiner shall fix a time for filing any objections to the
exception and any supporting reasons. Thereafter, the Assistant
Secretary, after consideration of the exceptions and any supporting
briefs filed therewith and of any objections to the exceptions and any
supporting reasons, may issue a final decision.
(2) An initial decision and a final decision made under this
paragraph shall include a statement of:
(i) Findings and conclusions, and the reasons or bases therefor, on
all issues presented; and
(ii) The terms and conditions of the rule or order made.
(3) A copy of an initial decision and a final decision under this
paragraph shall be served on each party.

fact is raised, the hearing examiner shall, and in any other case he
may, set the case for an evidentiary hearing in accordance with subpart
C of this part.

pending a decision on appeal by the Assistant Secretary.
[[Page 76]]
Sec. 1905.51 Finality for purposes of judicial review.

96 (62 FR 111, January 2, 1997).
Source: 49 FR 25094, June 19, 1984, unless otherwise noted.
Sec. 1908.1 Purpose and scope.
(a) This part contains requirements for Cooperative Agreements
between states and the Federal Occupational Safety and Health
Administration (OSHA) under sections 21(c) of the Occupational Safety
and Health Act of 1970 (29 U.S.C. 651 et seq.) and section 21(d), the
Occupational Safety and Health Administration Compliance Assistance
Authorization Act of 1998 (which amends the Occupational Safety and
Health Act,) under which OSHA will utilize state personnel to provide
consultative services to employers. Priority in scheduling such
consultation visits must be assigned to requests received from small
businesses which are in higher hazard industries or have the most
hazardous conditions at issue in the request. Consultation programs
operated under the authority of a state plan approved under Section 18
of the Act (and funded under Section 23(g), rather than under a
Cooperative Agreement) which provide consultative services to private
sector employers, must be ``at least as effective as'' the section 21(d)
Cooperative Agreement programs established by this part. The service
will be made available at no cost to employers to assist them in
establishing effective occupational safety and health programs for
providing employment and places of employment which are safe and
healthful. The overall goal is to prevent the occurrence of injuries and
illnesses which may result from exposure to hazardous workplace
conditions and from hazardous work practices. The principal assistance
will be provided at the employer's worksite, but off-site assistance may
also be provided by telephone and correspondence and at locations other
than the employer's worksite, such as the consultation project offices.
At the worksite, the consultant will, within the scope of the employer's
request, evaluate the employer's program for providing employment and a
place of employment which is safe and healthful, as well as identify
specific hazards in the workplace, and will provide appropriate advice
and assistance in establishing or improving the employer's safety and
health program and in correcting any hazardous conditions identified.
(b) Assistance may include education and training of the employer,
the employer's supervisors, and the employer's other employees as needed
to make the employer self-sufficient in ensuring safe and healthful work
and working conditions. Although onsite consultation will be conducted
independent of any OSHA enforcement activity, and the discovery of
hazards will not mandate citation or penalties, the employer remains
under a statutory obligation to protect employees, and in certain
instances will be required to take necessary protective action. Employer
correction of hazards identified by the consultant during a
comprehensive workplace survey, and implementation of certain core
elements of an effective safety and health program and commitment to the
completion of others may serve as the basis for employer exemption from
certain OSHA
[[Page 77]]
enforcement activities. States entering into Agreements under this part
will receive ninety percent Federal reimbursement for allowable costs,
and will provide consultation to employers requesting the service,
subject to scheduling priorities, available resources, and any other
limitations established by the Assistant Secretary as part of the
Cooperative Agreement.
(c) States operating approved Plans under section 18 of the Act
shall, in accord with section 18(b), establish enforcement policies
applicable to the safety and health issues covered by the State Plan
which are at least as effective as the enforcement policies established
by this part, including a recognition and exemption program.

Sec. 1908.3 Eligibility and funding.
(a) State eligibility. Any state may enter into an agreement with
the Assistant Secretary to perform consultation for private sector
employers; except that a state having a plan approved under section 18
of the Act is eligible to participate in the program only if that Plan
does not include provisions for federally funded consultation to private
sector employers as a part of its plan.
(b) Reimbursement. (1) The Assistant Secretary will reimburse 90
percent of the costs incurred under a Cooperative Agreement entered into
pursuant to this part. Approved training of State staff operating under

[49 FR 25094, June 19, 1984, as amended at 65 FR 64291, Oct. 26, 2000]
Sec. 1908.4 Offsite consultation.
The State may provide consultative services to employers on
occupational safety and health issues by telephone and correspondence,
and at locations
[[Page 79]]
other than the employer's worksite, such as the consultation project
offices. It may, under limited conditions specified by the Assistant
Secretary, include training and education.
Sec. 1908.5 Requests and scheduling for onsite consultation.
(a) Encouraging requests--(1) State responsibility. The State shall
be responsible for encouraging employers to request consultative
assistance and shall publicize the availability of its consultative
service and the scope of the service which will be provided. The
Assistant Secretary will also engage in activities to publicize and
promote the program.
(2) Promotional methods. To inform employers of the availability of
its consultative service and to encourage requests, the State may use
methods such as the following:
(i) Paid newspaper advertisements;
(ii) Newspaper, magazine, and trade publication articles;
(iii) Special direct mailings or telephone solicitations to
establishments based on workers' compensation data or other appropriate
listings;
(iv) In-person visits to workplaces to explain the availability of
the service, and participation at employer conferences and seminars;
(v) Solicitation of support from State business and labor
organizations and leaders, and public officials;
(vi) Solicitation of publicizing by employers and employees who have
received consultative services;
(vii) Preparation and dissemination of publications, descriptive
materials, and other appropriate items on consultative services;
(viii) Free public service announcements on radio and television.
(3) Scope of service. In its publicity for the program, in response
to any inquiry, and before an employer's request for a consultative
visit may be accepted, the state shall clearly explain that the service
is provided at no cost to an employer with federal and state funds for
the purpose of assisting the employer in establishing and maintaining
effective programs for providing safe and healthful places of employment
for employees, in accord with the requirements of the applicable state
or federal laws and regulations. The state shall explain that while
utilizing this service, an employer remains under a statutory obligation
to provide safe and healthful work and working conditions for employees.
In addition, while the identification of hazards by a consultant will
not mandate the issuance of citations or penalties, the employer is
required to take necessary action to eliminate employee exposure to a
hazard which in the judgment of the consultant represents an imminent
danger to employees, and to take action to correct within a reasonable
time any serious hazards that are identified. The state shall emphasize,
however, that the discovery of such a hazard will not initiate any
enforcement activity, and that referral will not take place, unless the
employer fails to eliminate the identified hazard within the established
time frame. The state shall also explain the requirements for
participation in the recognition and exemption program as set forth in
Sec. 1908.7(b)(4), and shall ensure that the employer understands his
or her obligation to post the List of Hazards accompanying the
consultant's written report.
(b) Employer requests. (1) An onsite consultative visit will be
provided only at the request of the employer, and shall not result from
the enforcement of any right of entry under state law.
(2) When making a request, an employer in a small, high hazard
establishment shall generally be encouraged to include within the scope
of such request all working conditions at the worksite and the
employer's entire safety and health program. However, a more limited
scope may be encouraged in larger and less hazardous establishments.
Moreover, any employer may specify a more limited scope for the visit by
indicating working conditions, hazards, or situations on which onsite
consultation will be focused. When such limited requests are at issue,
the consultant will limit review and provide assistance only with
respect to those working conditions, hazards, or situations specified;
except that if the consultant observes, in the course of the onsite
visit, hazards which are outside the scope of the request, the
consultant must treat such hazards as
[[Page 80]]
though they were within the scope of the request.
(3) Employers may request onsite consultation to assist in the
abatement of hazards cited during an OSHA enforcement inspection.
However, an onsite consultative visit may not take place after an
inspection until the conditions set forth in Sec. 1908.7(b)(3) have
been met.
(c) Scheduling priority. Priority shall be assigned to requests from
businesses with the most hazardous operations, with primary attention to
smaller businesses. Preference shall be given to the smaller businesses
which are in higher hazard industries or which have the most hazardous
conditions at issue in the request.
[49 FR 25094, June 19, 1984, as amended at 65 FR 64291, Oct. 26, 2000]
Sec. 1908.6 Conduct of a visit.
(a) Preparation. (1) An onsite consultative visit shall be made only
after appropriate preparation by the consultant. Prior to the visit, the
consultant shall become familiar with as many factors concerning the
establishment's operation as possible. The consultant shall review all
applicable codes and standards. In addition, the consultant shall assure
that all necessary technical and personal protective equipment is
available and functioning properly.
(2) At the time of any promotional visit conducted by a consultant
to encourage the use of the onsite consultative services, a consultation
may be performed without delay if the employer so requests and the
consultant is otherwise prepared to conduct such consultation.
(b) Structured format. An initial onsite consultative visit will
consist of an opening conference, an examination of those aspects of the
employer's safety and health program which relate to the scope of the
visit, a walkthrough of the workplace, and a closing conference. An
initial visit may include training and education for employers and
employees, if the need for such training and education is revealed by
the walkthrough of the workplace and the examination of the employer's
safety and health program, and if the employer so requests. The visit
shall be followed by a written report to the employer. Additional visits
may be conducted at the employer's request to provide needed education
and training, assistance with the employer's safety and health program,
technical assistance in the correction of hazards, or as necessary to
verify the correction of serious hazards identified during previous
visits. A compliance inspection may in some cases be the basis for a
visit limited to education and training, assistance with the employer's
safety and health program, or technical assistance in the correction of
hazards.
(c) Employee participation. (1) The consultant shall retain the
right to confer with individual employees during the course of the visit
in order to identify and judge the nature and extent of particular
hazards within the scope of the employer's request, and to evaluate the
employer's safety and health program. The consultant shall explain the
necessity for this contact to the employer during the opening
conference, and an employer must agree to permit such contact before a
visit can proceed.
(2)(i) In addition, an employee representative of affected employees
must be afforded an opportunity to accompany the consultant and the
employer's representative during the physical inspection of the
workplace. The consultant may permit additional employees (such as
representatives of a joint safety and health committee, if one exists at
the worksite) to participate in the walkaround, where the consultant
determines that such additional representatives will further aid the
visit.
(ii) If there is no employee representative, or if the consultant is
unable with reasonable certainty to determine who is such a
representative, or if the employee representative declines the offer to
participate, the consultant must confer with a reasonable number of
employees concerning matters of occupational safety and health.
(iii) The consultant is authorized to deny the right to accompany
under this section to any person whose conduct interferes with the
orderly conduct of the visit.
(d) Opening and closing conferences. (1) The consultant will
encourage a joint opening conference with employer and employee
representatives. If there is an
[[Page 81]]
objection to a joint conference, the consultant will conduct separate
conferences with employer and employee representatives. The consultant
must inform affected employees, with whom he confers, of the purpose of
the consultation visit.
(2) In addition to the requirements of paragraph (c) of this
section, the consultant will, in the opening conference, explain to the
employer the relationship between onsite consultation and OSHA
enforcement activity, explain the obligation to protect employees in the
event that certain hazardous conditions are identified, and emphasize
the employer's obligation to post the List of Hazards accompanying the
consultant's written report as described in paragraph (e)(8) of this
section.
(3) At the conclusion of the consultation visit, the consultant will
conduct a closing conference with employer and employee representatives,
jointly or separately. The consultant will describe hazards identified
during the visit and other pertinent issues related to employee safety
and health.
(e) Onsite activity. (1) Activity during the onsite consultative
visit will focus primarily on those areas, conditions, or hazards
regarding which the employer has requested assistance. An employer may
expand or reduce the scope of the request at any time during the onsite
visit. The consultant shall, if prepared and if scheduling priorities
permit, expand the scope of the visit at the time of the request. If the
employer's request for expansion necessitates further preparation by the
consultant or the expertise of another consultant, or if other employer
requests may merit higher priority, the consultant shall refer the
request to the consultation manager for scheduling. In all cases in
which the scope of the visit is reduced, the consultant remains
obligated to work with the employer to ensure correction of those
serious hazards which are identified during the visit.
(2) The consultant shall advise the employer as to the employer's
obligations and responsibilities under applicable Federal or State law
and implementing regulations.
(3) Within the scope of the employer's request, consultants shall
review the employer's safety and health program and provide advice on
modifications or additions to make such programs more effective.
(4) Consultants shall identify and provide advice on correction of
those hazards included in the employer's request and any other safety or
health hazards observed in the workplace during the course of the onsite
consultative visit. This advice shall include basic information
indicating the possibility of a solution and describing the general form
of the solution. The consultant shall conduct sampling and testing, with
subsequent analyses. as may be necessary to confirm the existence of
safety and health hazards.
(5) Advice and technical assistance on the correction of identified
safety and health hazards may be provided to employers during and after
the onsite consultative visit. Descriptive materials may be provided on
approaches, means, techniques, and other appropriate items commonly
utilized for the elimination or control of such hazards. The consultants
shall also advise the employers of additional sources of assistance, if
known.
(6) When a hazard is identified in the workplace, the consultant
shall indicate to the employer the consultant's best judgment as to
whether the situation would be classified as a ``serious'' or ``other-
than-serious'' hazard.
(7) At the time the consultant determines that a serious hazard
exists, the consultant will assist the employer to develop a specific
plan to correct the hazard, affording the employer a reasonable period
of time to complete the necessary action. The state must provide, upon
request from the employer within 15 working days of receipt of the
consultant's report, a prompt opportunity for an informal discussion
with the consultation manager regarding the period of time established
for the correction of a hazard or any other substantive finding of the
consultant.
(8) As a condition for receiving the consultation service, the
employer must agree to post the List of Hazards accompanying the
consultant's written report, and to notify affected employees when
hazards are corrected. When received, the List of Hazards must be
posted, unedited, in a prominent place
[[Page 82]]
where it is readily observable by all affected employees for 3 working
days, or until the hazards are corrected, whichever is later. A copy of
the List of Hazards must be made available to the employee
representative who participates in the visit. In addition, the employer
must agree to make information on the corrective actions proposed by the
consultant, as well as other-than-serious hazards identified, available
at the worksite for review by affected employees or the employee
representative. OSHA will not schedule a compliance inspection in
response to a complaint based upon a posted List of Hazards unless the
employer fails to meet his obligations under paragraph (f) of this
section, or fails to provide interim protection for exposed employees.
(f) Employer obligations. (1) An employer must take immediate action
to eliminate employee exposure to a hazard which, in the judgment of the
consultant, presents an imminent danger to employees. If the employer
fails to take the necessary action, the consultant must immediately
notify the affected employees and the appropriate OSHA enforcement
authority and provide the relevant information.
(2) An employer must also take the necessary action in accordance
with the plan developed under paragraph (e)(7) of this section to
eliminate or control employee exposure to any identified serious hazard,
and meet the posting requirements of paragraph (e)(8) of this section.
In order to demonstrate that the necessary action is being taken, an
employer may be required to submit periodic reports, permit a follow-up
visit, or take similar action that achieves the same end.
(3) An employer may request, and the consultation manager may grant,
an extension of the time frame established for correction of a serious
hazard when the employer demonstrates having made a good faith effort to
correct the hazard within the established time frame; shows evidence
that correction has not been completed because of factors beyond the
employer's reasonable control; and shows evidence that the employer is
taking all available interim steps to safeguard the employees against
the hazard during the correction period.
(4) If the employer fails to take the action necessary to correct a
serious hazard within the established time frame or any extensions
thereof, the consultation manager shall immediately notify the
appropriate OSHA enforcement authority and provide the relevant
information. The OSHA enforcement authority will make a determination,
based on a review of the facts, whether enforcement activity is
warranted.
(5) After correction of all serious hazards, the employer shall
notify the consultation manager by written confirmation of the
correction of the hazards, unless correction of the serious hazards is
verified by direct observation by the consultant.
(g) Written report. (1) A written report shall be prepared for each
visit which results in substantive findings or recommendations, and
shall be sent to the employer. The timing and format of the report shall
be approved by the Assistant Secretary. The report shall restate the
employer's request and describe the working conditions examined by the
consultant; shall, within the scope of the request, evaluate the
employer's program for ensuring safe and healthful employment and
provide recommendations for making such programs effective; shall
identify specific hazards and describe their nature, including reference
to applicable standards or codes; shall identify the seriousness of the
hazards; and, to the extent possible, shall include suggested means or
approaches to their correction. Additional sources of assistance shall
also be indicated, if known, including the possible need to procure
specific engineering consultation, medical advice and assistance, and
other appropriate items. The report shall also include reference to the
completion dates for the situations described in Sec. 1908.6(f) (1) and
(2).
(2) Because the consultant's written report contains information
considered confidential, and because disclosure of such reports would
adversely affect the operation of the OSHA consultation program, the
state shall not disclose the consultant's written report except to the
employer for whom it was prepared and as provided for in
[[Page 83]]
Sec. 1908.7(a)(3). The state may also disclose information contained in
the consultant's written report to the extent required by 29 CFR
1910.1020 or other applicable OSHA standards or regulations.
(h) Confidentiality. (1) The consultant shall preserve the
confidentiality of information obtained as the result of a consultative
visit which contains or might reveal a trade secret of the employer.
(2) Disclosure of consultation program information which identifies
employers who have requested the services of a consultant would
adversely affect the operation of the OSHA consultation program as well
as breach the confidentiality of commercial information not customarily
disclosed by the employer. Accordingly, the state shall keep such
information confidential. The state shall provide consultation program
information requested by OSHA, including information which identifies
employers who have requested consultation services. OSHA may use such
information to administer the consultation program and to evaluate state
and federal performance under that program, but shall, to the maximum
extent permitted by law, treat information which identifies specific
employers as exempt from public disclosure.

FR 64291, Oct. 26, 2000]
Sec. 1908.7 Relationship to enforcement.
(a) Independence. (1) Consultative activity by a State shall be
conducted independently of any OSHA enforcement activity.
(2) The consultative activity shall have its own identifiable
managerial staff. In States with Plans approved under section 18 of the
Act, this staff will be separate from the managing of compliance
inspections and scheduling.
(3) The identity of employers requesting onsite consultation, as
well as the file of the consultant's visit, shall not be provided to
OSHA for use in any compliance activity, except as provided for in Sec.
1908.6(f)(1) (failure to eliminate imminent danger,) Sec. 1908.6(f)(4)
(failure to eliminate serious hazards,) paragraph (b)(1) of this section
(inspection deferral) and paragraph (b)(4) of this section (recognition
and exemption program).
(b) Effect upon scheduling. (1) An onsite consultative visit already
in progress will have priority over OSHA compliance inspections except
as provided in paragraph (b)(2) of this section. The consultant and the
employer shall notify the compliance officer of the visit in progress
and request delay of the inspection until after the visit is completed.
An onsite consultative visit shall be considered ``in progress'' in
relation to the working conditions, hazards, or situations covered by
the visit from the beginning of the opening conference through the end
of the correction due dates and any extensions thereof. OSHA may, in
exercising its authority to schedule compliance inspections, assign a
lower priority to worksites where consultation visits are scheduled.
(2) The consultant shall terminate an onsite consultative visit
already in progress where one of the following kinds of OSHA compliance
inspections is about to take place:
(i) Imminent danger investigations;
(ii) Fatality/catastrophe investigations;
(iii) Complaint investigations;
(iv) Other critical inspections as determined by the Assistant
Secretary.
(3) An onsite consultation visit may not take place while an OSHA
enforcement inspection is in progress at the establishment. An
enforcement inspection shall be deemed ``in progress'' from the time a
compliance officer initially seeks entry to the workplace to the end of
the closing conference. An enforcement inspection will also be
considered ``in progress'' in cases where entry is refused, until such
times as: the inspection is conducted; the RA determines that a warrant
to require entry to the workplace will not be sought; or the RA
determines that allowing a consultative visit to proceed is in the best
interest of employee safety and health. An onsite consultative visit
shall not take place subsequent to an OSHA enforcement inspection until
a determination has been made that no citation will be issued, or if a
citation
[[Page 84]]
is issued, onsite consultation shall only take place with regard to
those citation items which have become final orders.
(4) The recognition and exemption program operated by the OSHA
consultation projects provide incentives and support to smaller, high-
hazard employers to work with their employees to develop, implement, and
continuously improve the effectiveness of their workplace safety and
health management system.
(i) Programmed Inspection Schedule. (A) When an employer requests
participation in a recognition and exemption program, and undergoes a
consultative visit covering all conditions and operations in the place
of employment related to occupational safety and health; corrects all
hazards that were identified during the course of the consultative visit
within established time frames; has began to implement all the elements
of an effective safety and health program; and agrees to request a
consultative visit if major changes in working conditions or work
processes occur which may introduce new hazards, OSHA's Programmed
Inspections at that particular site may be deferred while the employer
is working to achieve recognition and exemption status.
(B) Employers who meet all the requirements for recognition and
exemption will have the names of their establishments removed from
OSHA's Programmed Inspection Schedule for a period of not less than one
year. The exemption period will extend from the date of issuance by the
Regional Office of the certificate of recognition.
(ii) Inspections. OSHA will continue to make inspections in the
following categories at sites that achieved recognition status and have
been granted exemption from OSHA's Programmed Inspection Schedule; and
at sites granted inspection deferrals as provided for under paragraph
(b)(4)(i)(A) of this section:
(A) Imminent danger.
(B) Fatality/Catastrophe.
(C) Formal Complaints.
(5) When an employer requests consideration for participation in the
recognition and exemption program under paragraph (b)(4) of this
section, the provisions of Sec. 1908.6(e)(7), (e)(8), (f)(3), and
(f)(5) shall apply to other-than-serious hazards as well as serious
hazards.
(c) Effect upon enforcement. (1) The advice of the consultant and
the consultant's written report will not be binding on a compliance
officer in a subsequent enforcement inspection. In a subsequent
inspection, a compliance officer is not precluded from finding hazardous
conditions, or violations of standards, rules or regulations, for which
citations would be issued and penalties proposed.
(2) The hazard identification and correction assistance given by a
State consultant, or the failure of a consultant to point out a specific
hazard, or other possible errors or omissions by the consultant, shall
not be binding upon a compliance officer and need not affect the regular
conduct of a compliance inspection or preclude the finding of alleged
violations and the issuance of citations, or constitute a defense to any
enforcement action.
(3) In the event of a subsequent inspection, the employer is not
required to inform the compliance officer of the prior visit. The
employer is not required to provide a copy of the state consultant's
written report to the compliance officer, except to the extent that
disclosure of information contained in the report is required by 29 CFR
1910.1020 or other applicable OSHA standard or regulation. If, during a
subsequent enforcement investigation, OSHA independently determines
there is reason to believe that the employer: failed to correct serious
hazards identified during the course of a consultation visit; created
the same hazard again; or made false statements to the state or OSHA in
connection with participation in the consultation program, OSHA may
exercise its authority to obtain the consultation report.
(4) If, however, the employer chooses to provide a copy of the
consultant's report to a compliance officer, it may be used as a factor
in determining the extent to which an inspection is required and as a
factor in determining proposed penalties. When, during the course of a
compliance inspection, an OSHA compliance officer identifies the
existence of serious hazards previously
[[Page 85]]
identified as a result of a consultative visit, the Area Director shall
have authority to assess minimum penalties if the employer is in good
faith complying with the recommendations of a consultant after such
consultative visit.

Sec. 1908.8 Consultant specifications.
(a) Number. (1) The number of consultant positions which will be
funded under a Cooperative Agreement pursuant to this part for the
purpose of providing consultation to private sector employers will be
determined by the Assistant Secretary on the basis of program
performance, demand for services, industrial mix, resources available,
and the recommendation of the RA, and may be adjusted periodically.
(2) States shall make efforts to utilize consultants with the safety
and health expertise necessary to properly meet the demand for
consultation by the various industries within a State. The RA will
determine and negotiate a reasonable balance with the State on an annual

and health. They must demonstrate adequate education and experience to
satisfy the RA before assignment to work under an Agreement, and
annually thereafter, that they meet the requirements set out in Sec.
1908.8(b)(2), and that they have the ability to perform satisfactorily
pursuant to the Cooperative Agreement. Persons who have the potential
but do not yet demonstrate adequate education and experience to satisfy
the RA that they have the ability to perform consultant duties
independently may, with RA approval, be trained under a Cooperative
Agreement to perform consultant duties. Such persons may not, however,
perform consultant duties independently until it has been determined by
the RA that they meet the requirements and have the ability indicated.
All consultants shall be selected in accordance with the provisions of
Executive Order 11246 of September 24, 1965, as amended, entitled
``Equal Employment Opportunity.''
(2) Minimum requirements of consultants shall include the following:
(i) The ability to identify hazards; the ability to assess employee
exposure and risk; knowledge of OSHA standards; knowledge of hazard
correction techniques and practices; knowledge of workplace safety and
health program requirements; and the ability to effectively communicate,
both orally and in writing.
(ii) Consultants shall meet any additional degree and/or experience
requirements as may be established by the Assistant Secretary.
(c) Training. As necessary, the Assistant Secretary will specify
immediate and continuing training requirements for consultants. Expenses
for training which is required by the Assistant Secretary or approved by

Sec. 1908.9 Monitoring and evaluation.
(a) Assistant Secretary responsibility. A State's performance under
a Cooperative Agreement will be regularly monitored and evaluated by the
Assistant Secretary as part of a systematic Federal plan for this
activity. The Assistant Secretary may require changes as a result of
these evaluations to foster conformance with consultation policy. If the
State policies or practices which require change are such that the
State's assurance of correction of serious hazards and of the
effectiveness of employers' safety and health programs is in doubt, the
Assistant Secretary may, pending the completion of the changes, suspend
recognition of a State's consultative visits as a basis for exemption
from compliance inspection as permitted under Sec. 1908.7(b)(4).
(b) Consultant performance--(1) State activity. The State shall
establish and maintain an organized consultant performance monitoring
system under the Cooperative Agreement:
(i) Operation of the system shall conform to all requirements
established by the Assistant Secretary. The system shall be approved by
the Assistant Secretary before it is placed in operation.
[[Page 86]]
(ii) A performance evaluation of each State consultant performing
consultation services for employers shall be prepared annually. All
aspects of a consultant's performance shall be reviewed at that time.
Recommendation for remedial action shall be made and acted upon. The
annual evaluation report shall be a confidential State personnel record
and may be timed to coincide with regular personnel evaluations.
(iii) Performance of individual consultants shall be measured in
terms of their ability to identify hazards in the workplaces which they
have visited; their ability to determine employee exposure and risk, and
in particular their performance under Sec. 1908.6 (e) and (f); their
knowledge and application of applicable Federal or State statutes,
regulations or standards; their knowledge and application of appropriate
hazard correction techniques and approaches; their knowledge and
application of the requirements of an effective workplace safety and
health program; and their ability to communicate effectively their
findings and recommendations and the reasons for them to employers, and
relevant information, skills and techniques to employers and employees.
(iv) Accompanied visits to observe consultants during onsite
consultative visits shall be conducted periodically in accord with a
plan established in each annual Cooperative Agreement. The State may
also conduct unaccompanied visits to workplaces which received onsite
consultation, for the purpose of evaluating consultants. A written
report of each visit shall be provided to the consultant. These visits
shall be conducted only with the expressed permission of the employer
who requests the onsite consultative visit.
(v) The State will report quarterly to the RA on system operations,
including copies of accompanied visit reports completed that quarter.
(2) Federal activity. State consultant performance monitoring as set
out in Sec. 1908.9(b)(1) shall not preclude Federal monitoring activity
by methods determined to be appropriate by the Assistant Secretary.
(c) State reporting. For Federal monitoring and evaluation purposes,
the State shall compile and submit such factual and statistical data in
the format and at the frequency required by the Assistant Secretary. The
State shall prepare and submit to the RA any narrative reports,
including copies of written reports to employers as may be required by
the Assistant Secretary.

Sec. 1908.10 Cooperative Agreements.
(a) Who may make Agreements. The Assistant Secretary may make a
Cooperative Agreement under this part with the Governor of a State or
with any State agency designated for that purpose by the Governor.
(b) Negotiations. (1) Procedures for negotiations may be obtained
through the RA who will negotiate for the Assistant Secretary and make
final recommendations on each Agreement to the Assistant Secretary.
(2) States with Plans approved under section 18 of the Act may
initiate negotiations in anticipation of the withdrawal from the Plan of
Federally funded onsite consultation services to private sector
employers.
(3) Renegotiation of existing Agreements funded under this part
shall be initiated within 30 days of the effective date of these
revisions.
(c) Contents of Cooperative Agreement. (1) Any Agreement and
subsequent modifications shall be in writing and signed by both parties.

A-25 (dated July 8, 1993) (58 FR 38142, July 15, 1993).
Sec. 1910.1 Purpose and scope.
(a) Section 6(a) of the Williams-Steiger Occupational Safety and
Health Act of 1970 (84 Stat. 1593) provides that ``without regard to
chapter 5 of title 5, United States Code, or to the other subsections of
this section, the Secretary shall, as soon as practicable during the
period beginning with the effective date of this Act and ending 2 years
after such date, by rule promulgate as an occupational safety or health
standard any national consensus standard, and any established Federal
standard, unless he determines that the promulgation of such a standard
would not result in improved safety or health for specifically
designated employees.'' The legislative purpose of this provision is to
establish, as rapidly as possible and without regard to the rule-making
provisions of the Administrative Procedure Act, standards with which
industries are generally familiar, and on whose adoption interested and
affected persons have already had an opportunity to express their views.
Such standards are either (1) national concensus standards on whose
adoption affected persons have reached substantial agreement, or (2)
Federal standards already established by Federal statutes or
regulations.
(b) This part carries out the directive to the Secretary of Labor
under section 6(a) of the Act. It contains occupational safety and
health standards which have been found to be national consensus
standards or established Federal standards.
Sec. 1910.2 Definitions.
As used in this part, unless the context clearly requires otherwise:
(a) Act means the Williams-Steiger Occupational Safety and Health
Act of 1970 (84 Stat. 1590).
(b) Assistant Secretary of Labor means the Assistant Secretary of
Labor for Occupational Safety and Health;
(c) Employer means a person engaged in a business affecting commerce
who has employees, but does not include the United States or any State
or political subdivision of a State;
(d) Employee means an employee of an employer who is employed in a
business of his employer which affects commerce;
(e) Commerce means trade, traffic, commerce, transportation, or
communication among the several States, or between a State and any place
outside thereof, or within the District of Columbia, or a possession of
the United States (other than the Trust Territory of the Pacific
Islands), or between points in the same State but through a point
outside thereof;
(f) Standard means a standard which requires conditions, or the
adoption or use of one or more practices, means, methods, operations, or
processes, reasonably necessary or appropriate to provide safe or
healthful employment and places of employment;
(g) National consensus standard means any standard or modification
thereof which (1) has been adopted and promulgated by a nationally
recognized standards-producing organization under procedures whereby it
can be determined by the Secretary of Labor or by the Assistant
Secretary of Labor that persons interested and affected by the scope or
provisions of the standard have reached substantial agreement on its
adoption, (2) was formulated in a manner which afforded an opportunity
for diverse views to be considered, and (3) has been designated as such
a standard by the Secretary or the Assistant Secretary,
[[Page 91]]
after consultation with other appropriate Federal agencies; and
(h) Established Federal standard means any operative standard
established by any agency of the United States and in effect on April
28, 1971, or contained in any Act of Congress in force on the date of
enactment of the Williams-Steiger Occupational Safety and Health Act.
Sec. 1910.3 Petitions for the issuance, amendment, or repeal of
a standard.
(a) Any interested person may petition in writing the Assistant
Secretary of Labor to promulgate, modify, or revoke a standard. The
petition should set forth the terms or the substance of the rule
desired, the effects thereof if promulgated, and the reasons therefor.
(b)(1) The relevant legislative history of the Act indicates
congressional recognition of the American National Standards Institute
and the National Fire Protection Association as the major sources of
national consensus standards. National consensus standards adopted on
May 29, 1971, pursuant to section 6(a) of the Act are from those two
sources. However, any organization which deems itself a producer of
national consensus standards, within the meaning of section 3(9) of the
Act, is invited to submit in writing to the Assistant Secretary of Labor
at any time prior to February 1, 1973, all relevant information which
may enable the Assistant Secretary to determine whether any of its
standards satisfy the requirements of the definition of ``national
consensus standard'' in section 3(9) of the Act.
(2) Within a reasonable time after the receipt of a submission
pursuant to paragraph (b)(1) of this section, the Assistant Secretary of
Labor shall publish or cause to be published in the Federal Register a
notice of such submission, and shall afford interested persons a
reasonable opportunity to present written data, views, or arguments with
regard to the question whether any standards of the organization making
the submission are national consensus standards.
Sec. 1910.4 Amendments to this part.
(a) The Assistant Secretary of Labor shall have all of the authority
of the Secretary of Labor under sections 3(9) and 6(a) of the Act.
(b) The Assistant Secretary of Labor may at any time before April
28, 1973, on his own motion or upon the written petition of any person,
by rule promulgate as a standard any national consensus standard and any
established Federal standard, pursuant to and in accordance with section
6(a) of the Act, and, in addition, may modify or revoke any standard in
this part 1910. In the event of conflict among any such standards, the
Assistant Secretary of Labor shall take the action necessary to
eliminate the conflict, including the revocation or modification of a
standard in this part, so as to assure the greatest protection of the
safety or health of the affected employees.
Sec. 1910.5 Applicability of standards.
(a) Except as provided in paragraph (b) of this section, the
standards contained in this part shall apply with respect to employments
performed in a workplace in a State, the District of Columbia, the
Commonwealth of Puerto Rico, the Virgin Islands, American Samoa, Guam,
Trust Territory of the Pacific Islands, Wake Island, Outer Continental
Shelf lands defined in the Outer Continental Shelf Lands Act, Johnston
Island, and the Canal Zone.
(b) None of the standards in this part shall apply to working
conditions of employees with respect to which Federal agencies other
than the Department of Labor, or State agencies acting under section 274
of the Atomic Energy Act of 1954, as amended (42 U.S.C. 2021), exercise
statutory authority to prescribe or enforce standards or regulations
affecting occupational safety or health.
(c)(1) If a particular standard is specifically applicable to a
condition, practice, means, method, operation, or process, it shall
prevail over any different general standard which might otherwise be
applicable to the same condition, practice, means, method, operation, or
process. For example, Sec. 1915.23(c)(3) of this title prescribes
[[Page 92]]
personal protective equipment for certain ship repairmen working in
specified areas. Such a standard shall apply, and shall not be deemed
modified nor superseded by any different general standard whose
provisions might otherwise be applicable, to the ship repairmen working
in the areas specified in Sec. 1915.23(c)(3).
(2) On the other hand, any standard shall apply according to its
terms to any employment and place of employment in any industry, even
though particular standards are also prescribed for the industry, as in
subpart B or subpart R of this part, to the extent that none of such
particular standards applies. To illustrate, the general standard
regarding noise exposure in Sec. 1910.95 applies to employments and
places of employment in pulp, paper, and paperboard mills covered by
Sec. 1910.261.
(d) In the event a standard protects on its face a class of persons
larger than employees, the standard shall be applicable under this part
only to employees and their employment and places of employment.
(e) [Reserved]
(f) An employer who is in compliance with any standard in this part
shall be deemed to be in compliance with the requirement of section
5(a)(1) of the Act, but only to the extent of the condition, practice,
means, method, operation, or process covered by the standard.

(a) Application. This section shall apply only when the term
nationally recognized testing laboratory is used in other sections of
this part.
(b) Laboratory requirements. The term nationally recognized testing
laboratory (NRTL) means an organization which is recognized by OSHA in
accordance with appendix A of this section and which tests for safety,
and lists or labels or accepts, equipment or materials and which meets
all of the following criteria:
(1) For each specified item of equipment or material to be listed,
labeled or accepted, the NRTL has the capability (including proper
testing equipment and facilities, trained staff, written testing
procedures, and calibration and quality control programs) to perform:
(i) Testing and examining of equipment and materials for workplace
safety purposes to determine conformance with appropriate test
standards; or
(ii) Experimental testing and examining of equipment and materials
for workplace safety purposes to determine conformance with appropriate
test standards or performance in a specified manner.
(2) The NRTL shall provide, to the extent needed for the particular
equipment or materials listed, labeled, or accepted, the following
controls or services:
(i) Implements control procedures for identifying the listed and
labeled equipment or materials;
(ii) Inspects the run of production of such items at factories for
product evaluation purposes to assure conformance with the test
standards; and
(iii) Conducts field inspections to monitor and to assure the proper
use of its identifying mark or labels on products;
(3) The NRTL is completely independent of employers subject to the
tested equipment requirements, and of any manufacturers or vendors of
equipment or materials being tested for these purposes; and,
(4) The NRTL maintains effective procedures for:
(i) Producing creditable findings or reports that are objective and
without bias; and
(ii) Handling complaints and disputes under a fair and reasonable
system.
(c) Test standards. An appropriate test standard referred to in
Sec. 1910.7(b)(1) (i) and (ii) is a document which specifies the safety
requirements for specific equipment or class of equipment and is:
(1) Recognized in the United States as a safety standard providing
an adequate level of safety, and
(2) Compatible with and maintained current with periodic revisions
of applicable national codes and installation standards, and
(3) Developed by a standards developing organization under a method
providing for input and consideration of views of industry groups,
experts, users, consumers, governmental authorities, and others having
broad experience in the safety field involved, or
(4) In lieu of paragraphs (c) (1), (2), and (3), the standard is

(d) Alternative test standard. If a testing laboratory desires to
use a test standard other than one allowed under paragraph (c) of this
section, then the Assistant Secretary of Labor shall
[[Page 101]]
evaluate the proposed standard to determine that it provides an adequate
level of safety before it is used.
(e) Implementation. A testing organization desiring recognition by
OSHA as an NRTL shall request that OSHA evaluate its testing and control
programs against the requirements in this section for any equipment or
material it may specify. The recognition procedure shall be conducted in
accordance with appendix A to this section.
(f) Fees. (1) Each applicant for NRTL recognition and each NRTL must
pay fees for services provided by OSHA. OSHA will assess fees for the
following services:
(i) Processing of applications for initial recognition, expansion of
recognition, or renewal of recognition, including on-site reviews;
review and evaluation of the applications; and preparation of reports,
evaluations and Federal Register notices; and
(ii) Audits of sites.
(2) The fee schedule established by OSHA reflects the cost of
performing the activities for each service listed in paragraph (f)(1) of
this section. OSHA calculates the fees based on either the average or
actual time required to perform the work necessary; the staff costs per
hour (which include wages, fringe benefits, and expenses other than
travel for personnel that perform or administer the activities covered
by the fees); and the average or actual costs for travel when on-site
reviews are involved. The formula for the fee calculation is as follows:
Activity Fee = [Average (or Actual) Hours to Complete the Activity x
Staff Costs per Hour] + Average (or Actual) Travel Costs
(3) (i) OSHA will review costs annually and will propose a revised
fee schedule, if warranted. In its review, OSHA will apply the formula
established in paragraph (f)(2) of this section to the current estimated
costs for the NRTL Program. If a change is warranted, OSHA will follow
the implementation table in paragraph (f)(4) of this section.
(ii) OSHA will publish all fee schedules in the Federal Register.
Once published, a fee schedule remains in effect until it is superseded
by a new fee schedule. Any member of the public may request a change to
the fees included in the current fee schedule. Such a request must
include appropriate documentation in support of the suggested change.
OSHA will consider such requests during its annual review of the fee
schedule.
(4) OSHA will implement fee assessment, collection, and payment as
follows:
------------------------------------------------------------------------
Approximate dates Action required
------------------------------------------------------------------------
I. Annual Review of Fee Schedule
------------------------------------------------------------------------
November 1........................ OSHA will publish any proposed new
Fee Schedule in the Federal
Register, if OSHA determines
changes in the schedule are
warranted.

III. Audit Fees
After audit performed............. OSHA will bill each existing NRTL
for the audit fees in effect at the
time of audit, but will reflect
actual travel costs and staff time
in the bill.
30 days after bill date........... NRTLs must pay audit fees; OSHA will
assess late fee if audit fees are
not paid.
45 days after bill date........... OSHA will send a letter to the NRTL
requesting immediate payment of the
audit fees and late fee

Appendix A to Sec. 1910.7--OSHA Recognition Process for Nationally
Recognized Testing Laboratories
Introduction
This appendix provides requirements and criteria which OSHA will use
to evaluate and recognize a Nationally Recognized Testing Laboratory
(NRTL). This process will include the evaluation of the product
evaluation and control programs being operated by the NRTL, as well as
the NRTL's testing facilities being used in its program. In the
evaluation of the NRTLs, OSHA will use either consensus-based standards
currently in use nationally, or other standards or criteria which may be
considered appropriate. This appendix implements the definition of NRTL
in 29 CFR 1910.7 which sets out the criteria that a laboratory must meet
to be recognized by OSHA (initially and on a continuing basis). The
appendix is broader in scope, providing procedures for renewal,
expansion and revocation of OSHA recognition. Except as otherwise
provided, the burden is on the applicant to establish by a preponderance
of the evidence that it is entitled to recognition as an NRTL. If
further detailing of these requirements and criteria will assist the
NRTLs or OSHA in this activity, this detailing will be done through
appropriate OSHA Program Directives.
I. Procedures for Initial OSHA Recognition
A. Applications.
1. Eligibility. a. Any testing agency or organization considering
itself to meet the definition of nationally recognized testing
laboratory as specified in Sec. 1910.7 may apply for OSHA recognition
as an NRTL.
b. However, in determining eligibility for a foreign-based testing
agency or organization, OSHA shall take into consideration the policy of
the foreign government regarding both the acceptance in that country of
testing data, equipment acceptances, and listings, and labeling, which
are provided through nationally recognized testing laboratories
recognized by the Assistant Secretary, and the accessibility to
government recognition or a similar system in that country by U.S.-based
safety-related testing agencies, whether recognized by the Assistant
Secretary or not, if such recognition or a similar system is required by
that country.
2. Content of application. a. The applicant shall provide sufficient
information and detail demonstrating that it meets the requirements set
forth in Sec. 1910.7, in order for an informed decision concerning
recognition to be made by the Assistant Secretary.
b. The applicant also shall identify the scope of the NRTL-related
activity for which the applicant wishes to be recognized. This will
include identifying the testing methods it will use to test or judge the
specific equipment and materials for which recognition is being
requested, unless such test methods are already specified in the test
standard. If requested to do so by OSHA, the applicant shall provide
documentation of the efficacy of these testing methods.
c. The applicant may include whatever enclosures, attachments, or
exhibits the applicant deems appropriate. The application need not be
submitted on a Federal form.
3. Filing office location. The application shall be filed with: NRTL
Recognition Program, Occupational Safety and Health Administration, U.S.
Department of Labor, 200 Constitution Avenue, NW., Washington, DC 20210.
4. Amendments and withdrawals. a. An application may be revised by
an applicant at any time prior to the completion of activity under
paragraph I.B.4. of this appendix.
b. An application may be withdrawn by an applicant, without
prejudice, at any time prior to the final decision by the Assistant
Secretary in paragraph I.B.7.c. of this appendix.
B. Review and Decision Process; Issuance or Renewal.
1. Acceptance and on-site review. a. Applications submitted by
eligible testing agencies will be accepted by OSHA, and their receipt
acknowledged in writing. After receipt of an application, OSHA may
request additional information if it believes information relevant to
the requirements for recognition has been omitted.
b. OSHA shall, as necessary, conduct an on-site review of the
testing facilities of the applicant, as well as the applicant's
administrative and technical practices, and, if necessary, review any
additional documentation underlying the application.
c. These on-site reviews will be conducted by qualified individuals
technically expert in these matters, including, as appropriate, non-
Federal consultants/contractors acceptable to OSHA. The protocol for
each review will be based on appropriate national consensus standards or
international guides, with such additions, changes, or deletions as may
be considered necessary and appropriate in each case by OSHA. A written
report shall be made of each on-site review and a copy shall be provided
to the applicant.
2. Positive finding by staff. If, after review of the application,
and additional information, and the on-site review report, the applicant
appears to have met the requirements for recognition, a written
recommendation shall be submitted by the responsible OSHA personnel to
the Assistant Secretary that the application be approved, accompanied by
a supporting explanation.
[[Page 103]]
3. Negative finding by staff.--a. Notification to applicant. If,
after review of the application, any additional information and the on-
site review report, the applicant does not appear to have met the
requirements for recognition, the responsible OSHA personnel shall
notify the applicant in writing, listing the specific requirements of
Sec. 1910.7 and this appendix which the applicant has not met, and
allow a reasonable period for response.
b. Revision of application. (i) After receipt of a notification of
negative finding (i.e., for intended disapproval of the application),
and within the response period provided, the applicant may:
(a) Submit a revised application for further review, which could
result in a positive finding by the responsible OSHA personnel pursuant
to subsection I.B.2. of this appendix; or
(b) Request that the original application be submitted to the
Assistant Secretary with an attached statement of reasons, supplied by
the applicant of why the application should be approved.
(ii) This procedure for applicant notification and potential
revision shall be used only once during each recognition process.
4. Preliminary finding by Assistant Secretary. a. The Assistant
Secretary, or a special designee for this purpose, will make a
preliminary finding as to whether the applicant has or has not met the
requirements for recognition, based on the completed application file,
the written staff recommendation, and the statement of reasons supplied
by the applicant if there remains a staff recommendation of disapproval.
b. Notification of this preliminary finding will be sent to the
applicant and subsequently published in the Federal Register.
c. This preliminary finding shall not be considered an official
decision by the Assistant Secretary or OSHA, and does not confer any
change in status or any interim or temporary recognition for the
applicant.
5. Public review and comment period--a. The Federal Register notice
of preliminary finding will provide a period of not less than 30
calendar days for written comments on the applicant's fulfillment of the
requirements for recognition. The application, supporting documents,
staff recommendation, statement of applicant's reasons, and any comments
received, will be available for public inspection in the OSHA Docket
Office.
b. Any member of the public, including the applicant, may supply
detailed reasons and evidence supporting or challenging the sufficiency
of the applicant's having met the requirements of the definition in 29
CFR Sec. 1910.7 and this appendix. Submission of pertinent documents
and exhibits shall be made in writing by the close of the comment
period.
6. Action after public comment--a. Final decision by Assistant
Secretary. Where the public review and comment record supports the
Assistant Secretary's preliminary finding concerning the application,
i.e., absent any serious objections or substantive claims contrary to
the preliminary finding having been received in writing from the public
during the comment period, the Assistant Secretary will proceed to final
written decision on the application. The reasons supporting this
decision shall be derived from the evidence available as a result of the
full application, the supporting documentation, the staff finding, and
the written comments and evidence presented during the public review and
comment period.
b. Public announcement. A copy of the Assistant Secretary's final
decision will be provided to the applicant. Subsequently, a notification
of the final decision shall be published in the Federal Register. The
publication date will be the effective date of the recognition.
c. Review of final decision. There will be no further review
activity available within the Department of Labor from the final
decision of the Assistant Secretary.
7. Action after public objection--a. Review of negative information.
At the discretion of the Assistant Secretary or his designee, OSHA may
authorize Federal or contract personnel to initiate a special review of
any information provided in the public comment record which appears to
require resolution, before a final decision can be made.
b. Supplementation of record. The contents and results of special
reviews will be made part of this record by the Assistant Secretary by
either:
(i) Reopening the written comment period for public comments on
these reviews; or
(ii) Convening an informal hearing to accept public comments on
these reviews, conducted under applicable OSHA procedures for similar
hearings.
c. Final decision by the Assistant Secretary. The Assistant
Secretary shall issue a decision as to whether it has been demonstrated,
based on a preponderance of the evidence, that the applicant meets the
requirements for recognition. The reasons supporting this decision shall
be derived from the evidence available as a result of the full
application, the supporting documentation, the staff finding, the
comments and evidence presented during the public review and comment
period, and written to transcribed evidence received during any
subsequent reopening of the written comment period or informal public
hearing held.
d. Public announcement. A copy of the Assistant Secretary's final
decision will be provided to the applicant, and a notification will be
published in the Federal Register subsequently announcing the decision.
e. Review of final decision. There will be no further review
activity available within the Department of Labor from the final
decision of the Assistant Secretary.
[[Page 104]]
c. Terms and conditions of recognition. The following terms and
conditions shall be part of every recognition:
1. Letter of recognition. The recognition by OSHA of any NRTL will
be evidenced by a letter of recognition from OSHA. The letter will
provide the specific details of the scope of the OSHA recognition,
including the specific equipment or materials for which OSHA recognition
has been granted, as well as any specific conditions imposed by OSHA.
2. Period of recognition. The recognition by OSHA of each NRTL will

recognition.
II. Supplementary Procedures.
A. Test standard changes.
A recognized NRTL may change a testing standard or elements
incorporated in the standard such as testing methods or pass-fail
criteria by notifying the Assistant Secretary of the change, certifying
that the revised standard will be at least as effective as the prior
standard, and providing the supporting data upon which its conclusions
are based. The NRTL need not inform the Assistant Secretary of minor
deviations from a test standard such as the use of new instrumentation
that is more accurate or sensitive than originally called for in the
standard. The NRTL also need not inform the Assistant Secretary of its
adoption of revisions to third-party testing standards meeting the
requirements of Sec. 1910.7(c)(4), if such revisions have been
developed by the standards developing organization, or of its adoption
of revisions to other third-party test standards which the developing
organization has submitted to OSHA. If, upon review, the Assistant
Secretary or his designee determines that the proposed revised standard
is not ``substantially equivalent'' to the previous version with regard
to the level of safety obtained, OSHA will not accept the proposed
testing standard by the recognized NRTL, and will initiate
discontinuance of that aspect of OSHA-recognized activity by the NRTL by
modification of the official letter of recognition. OSHA will publicly
announce this action and the NRTL will be required to communicate this
OSHA decision directly to affected manufacturers.
B. Expansion of current recognition
1. Eligibility. A recognized NRTL may apply to OSHA for an expansion
of its current recognition to cover other categories of NRTL testing in
addition to those included in the current recognition.
2. Procedure. a. OSHA will act upon and process the application for
expansion in accordance with subsection I.B. of this appendix, except
that the period for written comments, specified in paragraph 5.a of
subsection I.B. of this appendix, will be not less than 15 calendar
days.
b. In that process, OSHA may decide not to conduct an on-site
review, where the substantive scope of the request to expand recognition
is closely related to the current area of recognition.
c. The expiration date for each expansion of recognition shall
coincide with the expiration date of the current basic recognition
period.
C. Renewal of OSHA recognition
1. Eligibility. A recognized NRTL may renew its recognition by
filing a renewal request at the address in paragraph I.A.3. of this
appendix not less than nine months, nor more than one year, before the
expiration date of its current recognition.
2. Procedure. a. OSHA will process the renewal request in accordance
with subsection I.B. of this appendix, except that the period for
written comments, specified in paragraph 5.a of subsection I.B. of this
appendix, will be not less than 15 calendar days.
b. In that process, OSHA may determine not to conduct the on-site
reviews in I.B.1.a. where appropriate.
c. When a recognized NRTL has filed a timely and sufficient renewal
request, its current recognition will not expire until a final decision
has been made by OSHA on the request.
d. After the first renewal has been granted to the NRTL, the NRTL
shall apply for a continuation of its recognition status every five
years by submitting a renewal request. In lieu of submitting a renewal
request after the initial renewal, the NRTL may certify
[[Page 105]]
its continuing compliance with the terms of its letter of recognition
and 29 CFR 1910.7.
3. Alternative procedure. After the initial recognition and before
the expiration thereof, OSHA may (for good cause) determine that there
is a sufficient basis to dispense with the renewal requirement for a
given laboratory and will so notify the laboratory of such a
determination in writing. In lieu of submitting a renewal request, any
laboratory so notified shall certify its continuing compliance with the
terms of its letter of recognition and 29 CFR 1910.7.
D. Voluntary termination of recognition.
At any time, a recognized NRTL may voluntarily terminate its
recognition, either in its entirety or with respect to any area covered
in its recognition, by giving written notice to OSHA. The written notice
shall state the date as of which the termination is to take effect. The
Assistant Secretary shall inform the public of any voluntary termination
by Federal Register notice.
E. Revocation of recognition by OSHA.
1. Potential causes. If an NRTL either has failed to continue to
substantially satisfy the requirements of Sec. 1910.7 or this appendix,
or has not been reasonably performing the NRTL testing requirements
encompassed within its letter of recognition, or has materially
misrepresented itself in its applications or misrepresented the scope or
conditions of its recognition, the Assistant Secretary may revoke the
recognition of a recognized NRTL, in whole or in part. OSHA may initiate
revocation procedures on the basis of information provided by any
interested person.
2. Procedure. a. Before proposing to revoke recognition, the Agency
will notify the recognized NRTL in writing, giving it the opportunity to
rebut or correct the alleged deficiencies which would form the basis of
the proposed revocation, within a reasonable period.
b. If the alleged deficiencies are not corrected or reconciled
within a reasonable period, OSHA will propose, in writing to the
recognized NRTL, to revoke recognition. If deemed appropriate, no other
announcement need be made by OSHA.
c. The revocation shall be effective in 60 days unless within that
period the recognized NRTL corrects the deficiencies or requests a
hearing in writing.
d. If a hearing is requested, it shall be held before an
administrative law judge of the Department of Labor pursuant to the
rules specified in 29 CFR part 1905, subpart C.
e. The parties shall be OSHA and the recognized NRTL. The Assistant
Secretary may allow other interested persons to participate in these
hearings if such participation would contribute to the resolution of
issues germane to the proceeding and not cause undue delay.
f. The burden of proof shall be on OSHA to demonstrate by a
preponderance of the evidence that the recognition should be revoked
because the NRTL is not meeting the requirements for recognition, has
not been reasonably performing the product testing functions as required
by Sec. 1910.7, this appendix A, or the letter of recognition, or has
materially misrepresented itself in its applications or publicity.
3. Final decision. a. After the hearing, the Administrative Law
Judge shall issue a decision stating the reasons based on the record as
to whether it has been demonstrated, based on a preponderance of
evidence, that the applicant does not continue to meet the requirements
for its current recognition.
b. Upon issuance of the decision, any party to the hearing may file
exceptions within 20 days pursuant to 29 CFR 1905.28. If no exceptions
are filed, this decision is the final decision of the Assistant
Secretary. If objections are filed, the Administrative Law Judge shall
forward the decision, exceptions and record to the Assistant Secretary
for the final decision on the proposed revocation.
c. The Assistant Secretary will review the record, the decision by
the Administrative Law Judge, and the exceptions filed. Based on this,
the Assistant Secretary shall issue the final decision as to whether it
has been demonstrated, by a preponderance of evidence, that the
recognized NRTL has not continued to meet the requirements for OSHA
recognition. If the Assistant Secretary finds that the NRTL does not
meet the NRTL recognition requirements, the recognition will be revoked.
4. Public announcement. A copy of the Assistant Secretary's final
decision will be provided to the applicant, and a notification will be
published in the Federal Register announcing the decision, and the
availability of the complete record of this proceeding at OSHA. The
effective date of any revocation will be the date the final decision
copy is sent to the NRTL.
5. Review of final decision. There will be no further review
activity available within the Department of Labor from the final
decision of the Assistant Secretary.

1911), 9-83 (48 FR 35736), 1-90 (55 FR 9033), or 6-96 (62 FR 111), as
applicable.
Sec. 1910.11 Scope and purpose.
(a) The provisions of this subpart B adopt and extend the
applicability of, established Federal standards in effect on April 28,
1971, with respect to every employer, employee, and employment covered
by the Act.
(b) It bears emphasis that only standards (i.e., substantive rules)
relating to safety or health are adopted by any incorporations by
reference of standards prescribed elsewhere in this chapter or this
title. Other materials contained in the referenced parties are not
adopted. Illustrations of the types of materials which are not adopted
are these. The incorporations by reference of parts 1915, 1916, 1917,
1918 in Sec. Sec. 1910.13, 1910.14, 1910.15, and 1910.16 are not
intended to include the discussion in those parts of the coverage of the
Longshoremen's and Harbor Workers' Compensation Act or the penalty
provisions of the Act. Similarly, the incorporation by reference of part
1926 in Sec. 1910.12 is not intended to include references to
interpretative rules having relevance to the application of the
Construction Safety Act, but having no relevance to the application to
the Occupational Safety and Health Act.
[[Page 107]]
Sec. 1910.12 Construction work.
(a) Standards. The standards prescribed in part 1926 of this chapter
are adopted as occupational safety and health standards under section 6
of the Act and shall apply, according to the provisions thereof, to
every employment and place of employment of every employee engaged in
construction work. Each employer shall protect the employment and places
of employment of each of his employees engaged in construction work by
complying with the appropriate standards prescribed in this paragraph.
(b) Definition. For purposes of this section, Construction work
means work for construction, alteration, and/or repair, including
painting and decorating. See discussion of these terms in Sec. 1926.13
of this title.
(c) Construction Safety Act distinguished. This section adopts as
occupational safety and health standards under section 6 of the Act the
standards which are prescribed in part 1926 of this chapter. Thus, the
standards (substantive rules) published in subpart C and the following
subparts of part 1926 of this chapter are applied. This section does not
incorporate subparts A and B of part 1926 of this chapter. Subparts A
and B have pertinence only to the application of section 107 of the
Contract Work Hours and Safety Standards Act (the Construction Safety
Act). For example, the interpretation of the term ``subcontractor'' in
paragraph (c) of Sec. 1926.13 of this chapter is significant in
discerning the coverage of the Construction Safety Act and duties
thereunder. However, the term ``subcontractor'' has no significance in
the application of the Act, which was enacted under the Commerce Clause
and which establishes duties for ``employers'' which are not dependent
for their application upon any contractual relationship with the Federal
Government or upon any form of Federal financial assistance.
(d) For the purposes of this part, to the extent that it may not
already be included in paragraph (b) of this section, ``construction
work'' includes the erection of new electric transmission and
distribution lines and equipment, and the alteration, conversion, and
improvement of the existing transmission and distribution lines and
equipment.
Sec. 1910.15 Shipyard employment.
(a) Adoption and extension of established safety and health
standards for shipyard employment. The standards prescribed by part 1915
(formerly parts 1501-1503) of this title and in effect on April 28, 1971
(as revised), are adopted as occupational safety or health standards
under section 6(a) of the Act and shall apply, according to the
provisions thereof, to every employment and place of employment of every
employee engaged in ship repair, shipbreaking, and shipbuilding, or a
related employment. Each employer shall protect the employment and
places of employment of each of his employees engaged in ship repair,
shipbreaking, and shipbuilding, or a related employment, by complying
with the appropriate standards prescribed by this paragraph.
(b) Definitions. For purposes of this section:
(1) Ship repair means any repair of a vessel, including, but not
restricted to, alterations, conversions, installations, cleaning,
painting, and maintenance work;
(2) Shipbreaking means any breaking down of a vessel's structure for
the purpose of scrapping the vessel, including the removal of gear,
equipment, or any component of a vessel;
(3) Shipbuilding means the construction of a vessel, including the
installation of machinery and equipment;
(4) Related employment means any employment performed as an incident
to, or in conjunction with, ship repair, shipbreaking, and shipbuilding
work, including, but not restricted to, inspection, testing, and
employment as a watchman; and
(5) Vessel includes every description of watercraft or other
artificial contrivance used, or capable of being used, as a means of
transportation on water, including special purpose floating structures
not primarily designed for, or used as a means of, transportation on
water.

Sec. 1910.24 Fixed industrial stairs.
(a) Application of requirements. This section contains
specifications for the safe design and construction of fixed general
industrial stairs. This classification includes interior and exterior
stairs around machinery, tanks, and other equipment, and stairs leading
to or from floors, platforms, or pits. This section does not apply to
stairs used for fire exit purposes, to construction operations to
private residences, or to articulated stairs, such as may be installed
on floating roof tanks or on dock facilities, the angle of which changes
with the rise and fall of the base support.
(b) Where fixed stairs are required. Fixed stairs shall be provided
for access from one structure level to another where operations
necessitate regular travel between levels, and for access to operating
platforms at any equipment which requires attention routinely during
operations. Fixed stairs shall also be provided where access to
elevations is daily or at each shift for such purposes as gauging,
inspection, regular maintenance, etc., where such work may expose
employees to acids, caustics, gases, or other
[[Page 121]]
harmful substances, or for which purposes the carrying of tools or
equipment by hand is normally required. (It is not the intent of this
section to preclude the use of fixed ladders for access to elevated
tanks, towers, and similar structures, overhead traveling cranes, etc.,
where the use of fixed ladders is common practice.) Spiral stairways
shall not be permitted except for special limited usage and secondary
access situations where it is not practical to provide a conventional
stairway. Winding stairways may be installed on tanks and similar round
structures where the diameter of the structure is not less than five (5)
feet.
(c) Stair strength. Fixed stairways shall be designed and
constructed to carry a load of five times the normal live load
anticipated but never of less strength than to carry safely a moving
concentrated load of 1,000 pounds.
(d) Stair width. Fixed stairways shall have a minimum width of 22
inches.
(e) Angle of stairway rise. Fixed stairs shall be installed at
angles to the horizontal of between 30[deg] and 50[deg]. Any uniform
combination of rise/tread dimensions may be used that will result in a
stairway at an angle to the horizontal within the permissible range.
Table D-1 gives rise/tread dimensions which will produce a stairway
within the permissible range, stating the angle to the horizontal
produced by each combination. However, the rise/tread combinations are
not limited to those given in Table D-1.

cleaned of oil, grease, or slippery materials. This can easily be done
with a solvent or steam cleaning.
(vii) Ladders having defects are to be marked and taken out of
service until repaired by either maintenance department or the
manufacturer.
(3) Use of ladders. (i). A simple rule for setting up a ladder at
the proper angle is to place the base a distance from the vertical wall
equal to one-fourth the working length of the ladder.
(ii) Portable ladders are designed as a one-man working ladder based
on a 200-pound load.
(iii) The ladder base section must be placed with a secure footing.
(iv) The top of the ladder must be placed with the two rails
supported, unless equipped with a single support attachment.
(v) When ascending or descending, the climber must face the ladder.
(vi) Ladders must not be tied or fastened together to provide longer
sections. They must be equipped with the hardware fittings necessary if
the manufacturer endorses extended uses.
(vii) Ladders should not be used as a brace, skid, guy or gin pole,
gangway, or for other uses than that for which they were intended,
unless specifically recommended for use by the manufacturer.

Sec. 1910.27 Fixed ladders.
(a) Design requirements--(1) Design considerations. All ladders,
appurtenances, and fastenings shall be designed to meet the following
load requirements:
(i) The minimum design live load shall be a single concentrated load
of 200 pounds.
(ii) The number and position of additional concentrated live-load
units of 200 pounds each as determined from anticipated usage of the
ladder shall be considered in the design.
(iii) The live loads imposed by persons occupying the ladder shall
be considered to be concentrated at such points as will cause the
maximum stress in the structural member being considered.
(iv) The weight of the ladder and attached appurtenances together
with the live load shall be considered in the design of rails and
fastenings.
(2) Design stresses. Design stresses for wood components of ladders
shall not exceed those specified in Sec. 1910.25. All wood parts of
fixed ladders shall meet the requirements of Sec. 1910.25(b).
For fixed ladders consisting of wood side rails and wood rungs or
cleats, used at a pitch in the range 75 degrees to 90 degrees, and
intended for use by no more than one person per section, single ladders
as described in Sec. 1910.25(c)(3)(ii) are acceptable.
(b) Specific features--(1) Rungs and cleats. (i) All rungs shall
have a minimum diameter of three-fourths inch for metal ladders, except
as covered in paragraph (b)(7)(i) of this section and a minimum diameter
of 1\1/8\ inches for wood ladders.
(ii) The distance between rungs, cleats, and steps shall not exceed
12 inches and shall be uniform throughout the length of the ladder.
(iii) The minimum clear length of rungs or cleats shall be 16
inches.
(iv) Rungs, cleats, and steps shall be free of splinters, sharp
edges, burrs, or projections which may be a hazard.
(v) The rungs of an individual-rung ladder shall be so designed that
the foot cannot slide off the end. A suggested design is shown in figure
D-1.
[GRAPHIC] [TIFF OMITTED] TC27OC91.001
Figure D-1--Suggested Design for Rungs on Individual-rung Ladders.
(2) Side rails. Side rails which might be used as a climbing aid
shall be of such cross sections as to afford adequate gripping surface
without sharp edges, splinters, or burrs.
(3) Fastenings. Fastenings shall be an integral part of fixed ladder
design.
(4) Splices. All splices made by whatever means shall meet design
requirements as noted in paragraph (a) of this section. All splices and
connections shall have smooth transition with original members and with
no sharp or extensive projections.
(5) Electrolytic action. Adequate means shall be employed to protect
dissimilar metals from electrolytic action when such metals are joined.
(6) Welding. All welding shall be in accordance with the ``Code for
Welding in Building Construction'' (AWSD1.0-1966).
(7) Protection from deterioration. (i) Metal ladders and
appurtenances shall be painted or otherwise treated to resist corrosion
and rusting when location demands. Ladders formed by individual metal
rungs imbedded in concrete, which serve as access to pits and to other
areas under floors, are frequently located in an atmosphere that causes
corrosion and rusting. To increase rung life in such atmosphere,
individual metal rungs shall have a minimum diameter of 1 inch or shall
be
[[Page 126]]
painted or otherwise treated to resist corrosion and rusting.
(ii) Wood ladders, when used under conditions where decay may occur,
shall be treated with a nonirritating preservative, and the details
shall be such as to prevent or minimize the accumulation of water on
wood parts.
(iii) When different types of materials are used in the construction
of a ladder, the materials used shall be so treated as to have no
deleterious effect one upon the other.

cleaners' anchor bolts shall not be used.
(27) Special precautions shall be taken to protect scaffold members,
including any wire or fiber ropes, when using a heat-producing process.
(b) General requirements for wood pole scaffolds. (1) Scaffold poles
shall bear on a foundation of sufficient size and strength to spread the
load from the poles over a sufficient area to prevent settlement. All
poles shall be set plumb.
(2) Where wood poles are spliced, the ends shall be squared and the
upper section shall rest squarely on the lower section. Wood splice
plates shall be provided on at least two adjacent sides and shall not be
less than 4 feet 0 inches in length, overlapping the abutted ends
equally, and have the same width and not less than the cross-sectional
area of the pole. Splice plates of other materials of equivalent
strength may be used.
(3) Independent pole scaffolds shall be set as near to the wall of
the building as practicable.
(4) All pole scaffolds shall be securely guyed or tied to the
building or structure. Where the height or length exceeds 25 feet, the
scaffold shall be secured at intervals not greater than 25 feet
vertically and horizontally.
(5) Putlogs or bearers shall be set with their greater dimensions
vertical, long enough to project over the ledgers of the inner and outer
rows of poles at least 3 inches for proper support.
(6) Every wooden putlog on single pole scaffolds shall be reinforced
with a
[[Page 132]]
\3/16\x2-inch steel strip or equivalent secured to its lower edge
throughout its entire length.
(7) Ledgers shall be long enough to extend over two pole spaces.
Ledgers shall not be spliced between the poles. Ledgers shall be
reinforced by bearing blocks securely nailed to the side of the pole to
form a support for the ledger.

so the platform will be tight with no spaces through which tools or
fragments of material can fall.
(12) Where planking is lapped, each plank shall lap its end supports
at least 12 inches. Where the ends of planks abut each other to form a
flush floor, the butt joint shall be at the centerline of a pole. The
abutted ends shall rest on separate bearers. Intermediate beams shall be
provided where necessary to prevent dislodgment of planks due to
deflection, and the ends shall be nailed or cleated to prevent their
dislodgment.
(13) When a scaffold turns a corner, the platform planks shall be
laid to prevent tipping. The planks that meet the corner putlog at an
angle shall be laid first, extending over the diagonally placed putlog
far enough to have a good safe bearing, but not far enough to involve
any danger from tipping. The planking running in the opposite direction
at right angles shall be laid so as to extend over and rest on the first
layer of planking.
(14) When moving platforms to the next level, the old platform shall
be left undisturbed until the new putlogs or bearers have been set in
place, ready to receive the platform planks.
(15) Guardrails not less than 2 x 4 inches or the equivalent and not
less than 36 inches or more than 42 inches high, with a mid-rail, when
required, of 1 x 4-inch lumber or equivalent, and toeboards, shall be
installed at all open sides on all scaffolds more than 10 feet above the
ground or floor. Toeboards shall be a minimum of 4 inches in height.
Wire mesh shall be installed in accordance with paragraph (a)(17) of
this section.

1910.39 also cover the minimum requirements for emergency action plans
and fire prevention plans.
(c) Definitions.
Electroluminescent means a light-emitting capacitor. Alternating
current excites phosphor atoms when placed between the electrically
conductive surfaces to produce light. This light source is typically
contained inside the device.
Exit means that portion of an exit route that is generally separated
from other areas to provide a protected way of travel to the exit
discharge. An example of an exit is a two-hour fire resistance-rated
enclosed stairway that leads from the fifth floor of an office building
to the outside of the building.
Exit access means that portion of an exit route that leads to an
exit. An example of an exit access is a corridor on the fifth floor of
an office building that leads to a two-hour fire resistance-rated
enclosed stairway (the Exit).
Exit discharge means the part of the exit route that leads directly
outside or to a street, walkway, refuge area, public way, or open space
with access to the outside. An example of an exit discharge is a door at
the bottom of a two-hour fire resistance-rated enclosed stairway that
discharges to a place of safety outside the building.
Exit route means a continuous and unobstructed path of exit travel
from any point within a workplace to a place of safety (including refuge
areas). An exit route consists of three parts: The exit access; the
exit; and, the exit discharge. (An exit route includes all vertical and
horizontal areas along the route.)
High hazard area means an area inside a workplace in which
operations include high hazard materials, processes, or contents.
Occupant load means the total number of persons that may occupy a
workplace or portion of a workplace at any one time. The occupant load
of a workplace is calculated by dividing the gross floor area of the
workplace or portion of a workplace by the occupant load factor for that
particular type of workplace occupancy. Information regarding ``Occupant
load'' is located in NFPA 101-2000, Life Safety Code.
Refuge area means either:
(1) A space along an exit route that is protected from the effects
of fire by separation from other spaces within the building by a barrier
with at least a one-hour fire resistance-rating; or
(2) A floor with at least two spaces, separated from each other by
smoke-resistant partitions, in a building protected throughout by an
automatic sprinkler system that complies with Sec. 1910.159 of this
part.
Self-luminous means a light source that is illuminated by a self-
contained power source (e.g., tritium) and that operates independently
from external power sources. Batteries are not acceptable self-contained
power sources.
[[Page 148]]
The light source is typically contained inside the device.
[67 FR 67961, Nov. 7, 2002]
Sec. 1910.35 Compliance with NFPA 101-2000, Life Safety Code.
An employer who demonstrates compliance with the exit route
provisions of NFPA 101-2000, the Life Safety Code, will be deemed to be
in compliance with the corresponding requirements in Sec. Sec. 1910.34,
1910.36, and 1910.37.
[67 FR 67961, Nov. 7, 2002]
Sec. 1910.36 Design and construction requirements for exit routes.
(a) Basic requirements. Exit routes must meet the following design
and construction requirements:
(1) An exit route must be permanent. Each exit route must be a
permanent part of the workplace.
(2) An exit must be separated by fire resistant materials.
Construction materials used to separate an exit from other parts of the
workplace must have a one-hour fire resistance-rating if the exit
connects three or fewer stories and a two-hour fire resistance-rating if
the exit connects four or more stories.
(3) Openings into an exit must be limited. An exit is permitted to
have only those openings necessary to allow access to the exit from
occupied areas of the workplace, or to the exit discharge. An opening
into an exit must be protected by a self-closing fire door that remains
closed or automatically closes in an emergency upon the sounding of a
fire alarm or employee alarm system. Each fire door, including its frame
and hardware, must be listed or approved by a nationally recognized
testing laboratory. Section 1910.155(c)(3)(iv)(A) of this part defines
``listed'' and Sec. 1910.7 of this part defines a ``nationally
recognized testing laboratory.''
(b) The number of exit routes must be adequate--(1) Two exit routes.
At least two exit routes must be available in a workplace to permit
prompt evacuation of employees and other building occupants during an
emergency, except as allowed in paragraph (b)(3) of this section. The
exit routes must be located as far away as practical from each other so
that if one exit route is blocked by fire or smoke, employees can
evacuate using the second exit route.
(2) More than two exit routes. More than two exit routes must be
available in a workplace if the number of employees, the size of the
building, its occupancy, or the arrangement of the workplace is such
that all employees would not be able to evacuate safely during an
emergency.
(3) A single exit route. A single exit route is permitted where the
number of employees, the size of the building, its occupancy, or the
arrangement of the workplace is such that all employees would be able to
evacuate safely during an emergency.
Note to paragraph 1910.36(b): For assistance in determining the
number of exit routes necessary for your workplace, consult NFPA 101-
2000, Life Safety Code.
(c) Exit discharge. (1) Each exit discharge must lead directly
outside or to a street, walkway, refuge area, public way, or open space
with access to the outside.
(2) The street, walkway, refuge area, public way, or open space to
which an exit discharge leads must be large enough to accommodate the
building occupants likely to use the exit route.
(3) Exit stairs that continue beyond the level on which the exit
discharge is located must be interrupted at that level by doors,
partitions, or other effective means that clearly indicate the direction
of travel leading to the exit discharge.
(d) An exit door must be unlocked. (1) Employees must be able to
open an exit route door from the inside at all times without keys,
tools, or special knowledge. A device such as a panic bar that locks
only from the outside is permitted on exit discharge doors.
(2) Exit route doors must be free of any device or alarm that could
restrict emergency use of the exit route if the device or alarm fails.
(3) An exit route door may be locked from the inside only in mental,
penal, or correctional facilities and then only if supervisory personnel
are continuously on duty and the employer has a plan to remove occupants
from the facility during an emergency.
(e) A side-hinged exit door must be used. (1) A side-hinged door
must be
[[Page 149]]
used to connect any room to an exit route.
(2) The door that connects any room to an exit route must swing out
in the direction of exit travel if the room is designed to be occupied
by more than 50 people or if the room is a high hazard area (i.e.,
contains contents that are likely to burn with extreme rapidity or
explode).
(f) The capacity of an exit route must be adequate. (1) Exit routes
must support the maximum permitted occupant load for each floor served.
(2) The capacity of an exit route may not decrease in the direction
of exit route travel to the exit discharge.

Appendix to Subpart E of Part 1910--Exit Routes, Emergency Action Plans,
and Fire Prevention Plans
This appendix serves as a nonmandatory guideline to assist employers
in complying with the appropriate requirements of subpart E.
Sec. 1910.38 Employee emergency plans.
1. Emergency action plan elements. The emergency action plan should
address emergencies that the employer may reasonably expect in the
workplace. Examples are: fire; toxic chemical releases; hurricanes;
tornadoes; blizzards; floods; and others. The elements of the emergency
action plan presented in paragraph 1910.38(c) can be supplemented by the
following to more effectively achieve employee safety and health in an
emergency. The employer should list in detail the procedures to be taken
by those employees who have been selected to remain behind to care for
essential plant operations until their evacuation becomes absolutely
necessary. Essential plant operations may include the monitoring of
plant power supplies, water supplies, and other essential services which
cannot be shut down for every emergency alarm. Essential plant
operations may also include chemical or manufacturing processes which
must be shut down in stages or steps where certain employees must be
present to assure that safe shut down procedures are completed.
The use of floor plans or workplace maps which clearly show the
emergency escape routes should be included in the emergency action plan.
Color coding will aid employees in determining their route assignments.
The employer should also develop and explain in detail what rescue
and medical first aid duties are to be performed and by whom. All
employees are to be told what actions they are to take in these
emergency situations that the employer anticipates may occur in the
workplace.
2. Emergency evacuation. At the time of an emergency, employees
should know what type of evacuation is necessary and what their role is
in carrying out the plan. In some cases where the emergency is very
grave, total and immediate evacuation of all employees is necessary. In
other emergencies, a partial evacuation of nonessential employees with a
delayed evacuation of others may be necessary for continued plant
operation. In some cases, only those employees in the immediate area of
the fire may be expected to evacuate or move to a safe area such as when
a local application fire suppression system discharge employee alarm is
sounded. Employees must be sure that they know what is expected of them
in all such emergency possibilities which have been planned in order to
provide assurance of their safety from fire or other emergency.
The designation of refuge or safe areas for evacuation should be
determined and identified in the plan. In a building divided into fire
zones by fire walls, the refuge area may still be within the same
building but in a different zone from where the emergency occurs.
Exterior refuge or safe areas may include parking lots, open fields
or streets which are located away from the site of the emergency and
which provide sufficient space to accommodate the employees. Employees
should be instructed to move away from the exit discharge doors of the
building, and to avoid congregating close to the building where they may
hamper emergency operations.
3. Emergency action plan training. The employer should assure that
an adequate number of employees are available at all times during
working hours to act as evacuation
[[Page 152]]
wardens so that employees can be swiftly moved from the danger location
to the safe areas. Generally, one warden for each twenty employees in
the workplace should be able to provide adequate guidance and
instruction at the time of a fire emergency. The employees selected or
who volunteer to serve as wardens should be trained in the complete
workplace layout and the various alternative escape routes from the
workplace. All wardens and fellow employees should be made aware of
handicapped employees who may need extra assistance, such as using the
buddy system, and of hazardous areas to be avoided during emergencies.
Before leaving, wardens should check rooms and other enclosed spaces in
the workplace for employees who may be trapped or otherwise unable to
evacuate the area.
After the desired degree of evacuation is completed, the wardens
should be able to account for or otherwise verify that all employees are
in the safe areas.
In buildings with several places of employment, employers are
encouraged to coordinate their plans with the other employers in the
building. A building-wide or standardized plan for the whole building is
acceptable provided that the employers inform their respective employees
of their duties and responsibilities under the plan. The standardized
plan need not be kept by each employer in the multi-employer building,
provided there is an accessible location within the building where the
plan can be reviewed by affected employees. When multi-employer
building-wide plans are not feasible, employers should coordinate their
plans with the other employers within the building to assure that
conflicts and confusion are avoided during times of emergencies. In
multi-story buildings where more than one employer is on a single floor,
it is essential that these employers coordinate their plans with each
other to avoid conflicts and confusion.
4. Fire prevention housekeeping. The standard calls for the control
of accumulations of flammable and combustible waste materials.
It is the intent of this standard to assure that hazardous
accumulations of combustible waste materials are controlled so that a
fast developing fire, rapid spread of toxic smoke, or an explosion will
not occur. This does not necessarily mean that each room has to be swept
each day. Employers and employees should be aware of the hazardous
properties of materials in their workplaces, and the degree of hazard
each poses. Certainly oil soaked rags have to be treated differently
than general paper trash in office areas. However, large accumulations
of waste paper or corrugated boxes, etc., can pose a significant fire
hazard. Accumulations of materials which can cause large fires or
generate dense smoke that are easily ignited or may start from
spontaneous combustion, are the types of materials with which this
standard is concerned. Such combustible materials may be easily ignited
by matches, welder's sparks, cigarettes and similar low level energy
ignition sources.
5. Maintenance of equipment under the fire prevention plan. Certain
equipment is often installed in workplaces to control heat sources or to
detect fuel leaks. An example is a temperature limit switch often found
on deep-fat food fryers found in restaurants. There may be similar
switches for high temperature dip tanks, or flame failure and flashback
arrester devices on furnaces and similar heat producing equipment. If
these devices are not properly maintained or if they become inoperative,
a definite fire hazard exists. Again employees and supervisors should be
aware of the specific type of control devices on equipment involved with
combustible materials in the workplace and should make sure, through
periodic inspection or testing, that these controls are operable.
Manufacturers' recommendations should be followed to assure proper
maintenance procedures.

equipment in continuous contact with the building facade, and shall
prevent sudden horizontal movement of the platform. The system may be
used together with continuous positive building guide systems using tie-
in guides on the same building, provided the requirements for each
system are met.
(1) The maximum vertical interval between building anchors shall be
three floors or 50 feet (15.3 m), whichever is less.
(2) Building anchors shall be located vertically so that attachment
of the stabilizer ties will not cause the platform suspension ropes to
angulate the platform horizontally across the face of the building. The
anchors shall be positioned horizontally on the building face so as to
be symmetrical about the platform suspension ropes.
(3) Building anchors shall be easily visible to employees and shall
allow a stabilizer tie attachment for each of the platform suspension
ropes at each vertical interval. If more than two suspension ropes are
used on a platform, only the two building-side suspension ropes at the
platform ends shall require a stabilizer attachment.

local weather forecasts which predict wind velocities for the area.
(vi) On exterior installations, an anemometer shall be mounted on
the platform to provide information of on-site wind velocities prior to
and during the use of the platform. The anemometer may be a portable
(hand held) unit which is temporarily mounted during platform use.
(vii) Tools, materials and debris not related to the work in
progress shall not be allowed to accumulate on platforms. Stabilizer
ties shall be located so as to allow unencumbered passage along the full
length of the platform and shall be of such length so as not to become
entangled in rollers, hoists or other machinery.
(j) Personal fall protection. Employees on working platforms shall
be protected by a personal fall arrest system meeting the requirements
of appendix C, section I, of this standard, and as otherwise provided by
this standard.
Appendix A to Sec. 1910.66, Guidelines (Advisory)
1. Use of the Appendix. Appendix A provides examples of equipment
and methods to assist the employer in meeting the requirements of the
indicated provision of the standard. Employers may use other equipment
or procedures which conform to the requirements of the standard. This
appendix neither adds to nor detracts from the mandatory requirements
set forth in Sec. 1910.66.
2. Assurance. Paragraph (c) of the standard requires the building
owner to inform the employer in writing that the powered platform
installation complies with certain requirements of the standard, since
the employer may not have the necessary information to make these
determinations. The employer, however, remains responsible for meeting
these requirements which have not been set off in paragraph (c)(1).
3. Design Requirements. The design requirements for each
installation should be based on the limitations (stresses, deflections,
etc.), established by nationally recognized standards as promulgated by
the following organizations, or to equivalent standards:

4. Tie-in-guides. Indented mullions, T-rails or other equivalent
guides are acceptable as tie-in guides in a building face for a
continuous stabilization system. Internal guides are embedded in other
building members with only the opening exposed (see Figure 1 of appendix
B). External guides, however, are installed external to the other
building members and so are fully exposed. The minimum opening for tie-
in guides is three-quarters of an inch (19 mm), and the minimum inside
dimensions are one-inch (25 mm) deep and two inches (50 mm) wide.
Employers should be aware of the hazards associated with tie-in
guides in a continuous stabilization system which was not designed
properly. For example, joints in these track systems may become extended
or discontinuous due to installation or building settlement. If this
alignment problem is not corrected, the system could jam when a guide
roller or guide shoe strikes a joint and this would cause a hazardous
situation for employees. In another instance, faulty design will result
in guide rollers being mounted in a line so they will jam in the track
at the slightest misalignment.
5. Building anchors (intermittent stabilization system). In the
selection of the vertical distance between building anchors, certain
factors should be given consideration. These factors include building
height and architectural design, platform length and weight, wire rope
angulation, and the wind velocities in the building area. Another factor
to consider is the material of the building face, since this material
may be adversely affected by the building rollers.
External or indented type building anchors are acceptable.
Receptacles in the building facade used for the indented type should be
kept clear of extraneous materials which will hinder their use. During
the inspection of the platform installation, evidence of a failure or
abuse of the anchors should be brought to the attention of the employer.
6. Stabilizer tie length. A stabilizer tie should be long enough to
provide for the planned angulation of the suspension cables. However,
the length of the tie should not be excessive and become a problem by
possibly becoming entangled in the building face rollers or parts of the
platform machinery.
The attachment length may vary due to material elongation and this
should be considered when selecting the material to be used.
Consideration should also be given to the use of ties which are easily
installed by employees, since this will encourage their use.
7. Intermittent stabilization system. Intermittent stabilization
systems may use different equipment, tie-in devices and methods to
restrict the horizontal movement of a powered platform with respect to
the face of the building. One acceptable method employs corrosion-
resistant building anchors secured in the face of the building in
vertical rows every third floor or 50 feet (15.3 m), whichever is less.
The anchors are spaced horizontally to allow a stabilization attachment
(stabilizer tie) for each of the two platform suspension wire ropes. The
stabilizer tie consists of two parts. One part is a quick connect-quick
disconnect device which utilizes a corrosion-resistant yoke and retainer
spring that is designed to fit over the building anchors. The second
part of the stabilizer tie is a lanyard which is used to maintain a
fixed distance between the suspension wire rope and the face of the
building.
In this method, as the suspended powered platform descends past the
elevation of each anchor, the descent is halted and each of the platform
occupants secures a stabilizer tie between a suspension wire rope and a
building anchor. The procedure is repeated as each elevation of a
building anchor is reached during the descent of the powered platform.
As the platform ascends, the procedure is reversed; that is, the
stabilizer ties are removed as each elevation of a building anchor is
reached. The removal of each stabilizer tie is assured since the
platform is provided with stopping devices which will interrupt power to
its hoist(s) in the event either stopping device contacts a stabilizer
during the ascent of the platform.
Figure 2 of appendix B illustrates another type of acceptable
intermittent stabilization system which utilizes retaining pins as the
quick connect-quick disconnect device in the stabilizer tie.
8. Wire Rope Inspection. The inspection of the suspension wire rope
is important since the rope gradually loses strength during its useful
life. The purpose of the inspection is to determine whether the wire
rope has sufficient integrity to support a platform with the required
design factor.
If there is any doubt concerning the condition of a wire rope or its
ability to perform the required work, the rope should be replaced. The
cost of wire rope replacement is quite small if compared to the cost in
terms of human injuries, equipment down time and replacement.
No listing of critical inspection factors, which serve as a basis
for wire rope replacement in the standard, can be a substitute for an
experienced inspector of wire rope. The listing serves as a user's guide
to the accepted standards by which ropes must be judged.
Rope life can be prolonged if preventive maintenance is performed
regularly. Cutting off an appropriate length of rope at the end
termination before the core degrades and valley breaks appear minimizes
degradation at these sections.
[[Page 170]]
9. General Maintenance. In meeting the general maintenance
requirement in paragraph (h)(1) of the standard, the employer should
undertake the prompt replacement of broken, worn and damaged parts,
switch contacts, brushes, and short flexible conductors of electrical
devices. The components of the electrical service system and traveling
cables should be replaced when damaged or significantly abraded. In
addition, gears, shafts, bearings, brakes and hoisting drums should be
kept in proper alignment.
10. Training. In meeting the training requirement of paragraph
(i)(1) of the standard, employers should use both on the job training
and formal classroom training. The written work procedures used for this
training should be obtained from the manufacturer, if possible, or
prepared as necessary for the employee's information and use.
Employees who will operate powered platforms with intermittent
stabilization systems should receive instruction in the specific ascent
and descent procedures involving the assembly and disassembly of the
stabilizer ties.
An acceptable training program should also include employee
instruction in basic inspection procedures for the purpose of
determining the need for repair and replacement of platform equipment.
In addition, the program should cover the inspection, care and use of
the personal fall protection equipment required in paragraph (j)(1) of
the standard.
In addition, the training program should also include emergency
action plan elements. OSHA brochure 1B3088 (Rev.) 1985, ``How
to Prepare for Workplace Emergencies,'' details the basic steps needed
to prepare to handle emergencies in the workplace.
Following the completion of a training program, the employee should
be required to demonstrate competency in operating the equipment safely.
Supplemental training of the employee should be provided by the
employer, as necessary, if the equipment used or other working
conditions should change.
An employee who is required to work with chemical products on a
platform should receive training in proper cleaning procedures, and in
the hazards, care and handling of these products. In addition, the
employee should be supplied with the appropriate personal protective
equipment, such as gloves and eye and face protection.
11. Suspension and Securing of Powered Platforms (Equivalency). One
acceptable method of demonstrating the equivalency of a method of
suspending or securing a powered platform, as required in paragraphs
(e)(2)(iii), (f)(3) and (f)(5)(i)(F), is to provide an engineering
analysis by a registered professional engineer. The analysis should
demonstrate that the proposed method will provide an equal or greater
degree of safety for employees than any one of the methods specified in
the standard.

Appendix C to Sec. 1910.66--Personal Fall Arrest System (Section I--
Mandatory; Sections II and III--Non-Mandatory)
Use of the Appendix
Section I of appendix C sets out the mandatory criteria for personal
fall arrest systems used by all employees using powered platforms, as
required by paragraph (j)(1) of this standard. Section II sets out
nonmandatory test procedures which may be used to determine compliance
with applicable requirements contained in section I of this appendix.
Section III provides nonmandatory guidelines which are intended to
assist employers in complying with these provisions.
I. Personal fall arrest systems--(a) Scope and application. This
section establishes the application of and performance criteria for
personal fall arrest systems which are required for use by all employees
using powered platforms under paragraph 1910.66(j).
(b) Definitions. Anchorage means a secure point of attachment for
lifelines, lanyards or deceleration devices, and which is independent of
the means of supporting or suspending the employee.
Body belt means a strap with means both for securing it about the
waist and for attaching it to a lanyard, lifeline, or deceleration
device.
Body harness means a design of straps which may be secured about the
employee in a manner to distribute the fall arrest forces over at least
the thighs, pelvis, waist, chest and shoulders with means for attaching
it to other components of a personal fall arrest system.
Buckle means any device for holding the body belt or body harness
closed around the employee's body.
Competent person means a person who is capable of identifying
hazardous or dangerous conditions in the personal fall arrest system or
any component thereof, as well as in their application and use with
related equipment.
Connector means a device which is used to couple (connect) parts of
the system together. It may be an independent component of the system
(such as a carabiner), or an integral component of part of the system
(such as a buckle or dee-ring sewn into a body belt or body harness, or
a snap-hook spliced or sewn to a lanyard or self-retracting lanyard).
Deceleration device means any mechanism, such as a rope grab,
ripstitch lanyard, specially woven lanyard, tearing or deforming
lanyard, or automatic self retracting-lifeline/lanyard, which serves to
dissipate a substantial amount of energy during a fall arrest, or
otherwise limits the energy imposed on an employee during fall arrest.
Deceleration distance means the additional vertical distance a
falling employee travels, excluding lifeline elongation and free fall
distance, before stopping, from the point at which the deceleration
device begins to operate. It is measured as the distance between the
location of an employee's body belt or body harness attachment point at
the moment of activation (at the onset of fall arrest forces) of the
deceleration device during a fall, and the location of that attachment
point after the employee comes to a full stop.
Equivalent means alternative designs, materials or methods which the
employer can demonstrate will provide an equal or greater degree of
safety for employees than the methods, materials or designs specified in
the standard.
Free fall means the act of falling before the personal fall arrest
system begins to apply force to arrest the fall.
Free fall distance means the vertical displacement of the fall
arrest attachment point on the employee's body belt or body harness
between onset of the fall and just before the system begins to apply
force to arrest the fall. This distance excludes deceleration distance,
lifeline and lanyard elongation but includes any deceleration device
slide distance or self-retracting lifeline/lanyard extension before they
operate and fall arrest forces occur.
Lanyard means a flexible line of rope, wire rope, or strap which is
used to secure the body belt or body harness to a deceleration device,
lifeline, or anchorage.
Lifeline means a component consisting of a flexible line for
connection to an anchorage at one end to hang vertically (vertical
lifeline), or for connection to anchorages at both ends to stretch
horizontally (horizontal lifeline), and which serves as a means for
connecting other components of a personal fall arrest system to the
anchorage.
Personal fall arrest system means a system used to arrest an
employee in a fall from a working level. It consists of an anchorage,
connectors, a body belt or body harness and may include a lanyard,
deceleration device, lifeline, or suitable combinations of these.
Qualified person means one with a recognized degree or professional
certificate and extensive knowledge and experience in the subject field
who is capable of design, analysis, evaluation and specifications in the
subject work, project, or product.
Rope grab means a deceleration device which travels on a lifeline
and automatically frictionally engages the lifeline and locks so as to
arrest the fall of an employee. A rope grab usually employs the
principle of inertial locking, cam/lever locking, or both.
Self-retracting lifeline/lanyard means a deceleration device which
contains a drum-wound line which may be slowly extracted from, or
retracted onto, the drum under slight tension during normal employee
movement, and which, after onset of a fall, automatically locks the drum
and arrests the fall.
[[Page 175]]
Snap-hook means a connector comprised of a hookshaped member with a
normally closed keeper, or similar arrangement, which may be opened to
permit the hook to receive an object and, when released, automatically
closes to retain the object. Snap-hooks are generally one of two types:
1. The locking type with a self-closing, self-locking keeper which
remains closed and locked until unlocked and pressed open for connection
or disconnection, or
2. The non-locking type with a self-closing keeper which remains
closed until pressed open for connection or disconnection.
Tie-off means the act of an employee, wearing personal fall
protection equipment, connecting directly or indirectly to an anchorage.
It also means the condition of an employee being connected to an
anchorage.

(5) Self-retracting lifelines and lanyards which do not limit free
fall distance to two feet (0.61 m) or less, ripstitch lanyards, and
tearing and deforming lanyards shall be capable of sustaining a minimum
tensile load of 5,000 pounds (22.2 kN) applied to the device with the
lifeline or lanyard in the fully extended position.
(6) Dee-rings and snap-hooks shall be capable of sustaining a
minimum tensile load of 5,000 pounds (22.2 kN).

competent person to be undamaged and suitable for reuse.
(8) The employer shall provide for prompt rescue of employees in the
event of a fall or shall assure the self-rescue capability of employees.
(9) Before using a personal fall arrest system, and after any
component or system is changed, employees shall be trained in accordance
with the requirements of paragraph 1910.66(i)(1), in the safe use of the
system.
(f) Inspections. Personal fall arrest systems shall be inspected
prior to each use for mildew, wear, damage and other deterioration, and
defective components shall be removed from service if their strength or
function may be adversely affected.
II. Test methods for personal fall arrest systems (non-mandatory)--
(a) General. Paragraphs (b), (c), (d) and (e), of this section II set
forth test procedures which may be used to determine compliance with the
requirements in paragraph (d)(1)(i) through (d)(1)(iv) of section I of
this appendix.
(b) General conditions for all tests in section II. (1) Lifelines,
lanyards and deceleration devices should be attached to an anchorage and
connected to the body-belt or body harness in the same manner as they
would be when used to protect employees.
(2) The anchorage should be rigid, and should not have a deflection
greater than .04 inches (1 mm) when a force of 2,250 pounds (10 kN) is
applied.
(3) The frequency response of the load measuring instrumentation
should be 120 Hz.
(4) The test weight used in the strength and force tests should be a
rigid, metal, cylindrical or torso-shaped object with a girth of 38
inches plus or minus four inches (96 cm plus or minus 10 cm).
(5) The lanyard or lifeline used to create the free fall distance
should be supplied with the system, or in its absence, the least elastic
lanyard or lifeline available to be used with the system.
(6) The test weight for each test should be hoisted to the required
level and should be quickly released without having any appreciable
motion imparted to it.
(7) The system's performance should be evaluated taking into account
the range of environmental conditions for which it is designed to be
used.
(8) Following the test, the system need not be capable of further
operation.
(c) Strength test. (1) During the testing of all systems, a test
weight of 300 pounds plus or minus five pounds (135 kg plus or minus 2.5
kg) should be used. (See paragraph (b)(4), above.)
(2) The test consists of dropping the test weight once. A new unused
system should be used for each test.
(3) For lanyard systems, the lanyard length should be six feet plus
or minus two inches (1.83 m plus or minus 5 cm) as measured from the
fixed anchorage to the attachment on the body belt or body harness.
(4) For rope-grab-type deceleration systems, the length of the
lifeline above the centerline of the grabbing mechanism to the
lifeline's anchorage point should not exceed two feet (0.61 m).
(5) For lanyard systems, for systems with deceleration devices which
do not automatically limit free fall distance to two feet (0.61 m) or
less, and for systems with deceleration devices which have a connection
distance in excess of one foot (0.3 m) (measured between the centerline
of the lifeline and the attachment point to the body belt or harness),
the test weight should be rigged to free fall a distance of 7.5 feet
(2.3 m) from a point that is 1.5 feet (46 cm) above the anchorage point,
to its hanging location (six feet below the anchorage). The test weight
should fall without interference, obstruction, or hitting the floor or
ground during the test. In some cases a non-elastic wire lanyard of
sufficient length may need to be added to the system (for test purposes)
to create the necessary free fall distance.
(6) For deceleration device systems with integral lifelines or
lanyards which automatically limit free fall distance to two feet (0.61
m) or less, the test weight should be rigged to free fall a distance of
four feet (1.22 m).
(7) Any weight which detaches from the belt or harness should
constitute failure for the strength test.
(d) Force test--(1) General. The test consists of dropping the
respective test weight specified in (d)(2)(i) or (d)(3)(i) once. A new,
unused system should be used for each test.
(2) For lanyard systems. (i) A test weight of 220 pounds plus or
minus three pounds (100 kg plus or minus 1.6 kg) should be used. (See
paragraph (b)(4), above.)
(ii) Lanyard length should be six feet plus or minus two inches
(1.83 m plus or minus 5 cm) as measured from the fixed anchorage to the
attachment on the body belt or body harness.
[[Page 177]]
(iii) The test weight should fall free from the anchorage level to
its hanging location (a total of six feet (1.83 m) free fall distance)
without interference, obstruction, or hitting the floor or ground during
the test.
(3) For all other systems. (i) A test weight of 220 pounds plus or
minus three pounds (100 kg plus or minus 1.6 kg) should be used. (See
paragraph (b)(4), above.)
(ii) The free fall distance to be used in the test should be the
maximum fall distance physically permitted by the system during normal
use conditions, up to a maximum free fall distance for the test weight
of six feet (1.83 m), except as follows:
(A) For deceleration systems which have a connection link or
lanyard, the test weight should free fall a distance equal to the
connection distance (measured between the centerline of the lifeline and
the attachment point to the body belt or harness).
(B) For deceleration device systems with integral lifelines or
lanyards which automatically limit free fall distance to two feet (0.61
m) or less, the test weight should free fall a distance equal to that
permitted by the system in normal use. (For example, to test a system
with a self-retracting lifeline or lanyard, the test weight should be
supported and the system allowed to retract the lifeline or lanyard as
it would in normal use. The test weight would then be released and the
force and deceleration distance measured).
(4) A system fails the force test if the recorded maximum arresting
force exceeds 1,260 pounds (15.6 kN) when using a body belt, and/or
exceeds 2,520 pounds (11.2 kN) when using a body harness.
(5) The maximum elongation and deceleration distance should be
recorded during the force test.
(e) Deceleration device tests--(1) General. The device should be
evaluated or tested under the environmental conditions, (such as rain,
ice, grease, dirt, type of lifeline, etc.), for which the device is
designed.
(2) Rope-grab-type deceleration devices. (i) Devices should be moved
on a lifeline 1,000 times over the same length of line a distance of not
less than one foot (30.5 cm), and the mechanism should lock each time.
(ii) Unless the device is permanently marked to indicate the type(s)
of lifeline which must be used, several types (different diameters and
different materials), of lifelines should be used to test the device.
(3) Other self-activatinq-type deceleration devices. The locking
mechanisms of other self-activating-type deceleration devices designed
for more than one arrest should lock each of 1,000 times as they would
in normal service.
III. Additional non-mandatory guidelines for personal fall arrest
systems. The following information constitutes additional guidelines for
use in complying with requirements for a personal fall arrest system.
(a) Selection and use considerations. The kind of personal fall
arrest system selected should match the particular work situation, and
any possible free fall distance should be kept to a minimum.
Consideration should be given to the particular work environment. For
example, the presence of acids, dirt, moisture, oil, grease, etc., and
their effect on the system, should be evaluated. Hot or cold
environments may also have an adverse affect on the system. Wire rope
should not be used where an electrical hazard is anticipated. As
required by the standard, the employer must plan to have means available
to promptly rescue an employee should a fall occur, since the suspended
employee may not be able to reach a work level independently.
Where lanyards, connectors, and lifelines are subject to damage by
work operations such as welding, chemical cleaning, and sandblasting,
the component should be protected, or other securing systems should be
used. The employer should fully evaluate the work conditions and
environment (including seasonal weather changes) before selecting the
appropriate personal fall protection system. Once in use, the system's
effectiveness should be monitored. In some cases, a program for cleaning
and maintenance of the system may be necessary.
(b) Testing considerations. Before purchasing or putting into use a
personal fall arrest system, an employer should obtain from the supplier
information about the system based on its performance during testing so
that the employer can know if the system meets this standard. Testing
should be done using recognized test methods. Section II of this
appendix C contains test methods recognized for evaluating the
performance of fall arrest systems. Not all systems may need to be
individually tested; the performance of some systems may be based on
data and calculations derived from testing of similar systems, provided
that enough information is available to demonstrate similarity of
function and design.
(c) Component compatibility considerations. Ideally, a personal fall
arrest system is designed, tested, and supplied as a complete system.
However, it is common practice for lanyards, connectors, lifelines,
deceleration devices, body belts and body harnesses to be interchanged
since some components wear out before others. The employer and employee
should realize that not all components are interchangeable. For
instance, a lanyard should not be connected between a body belt (or
harness) and a deceleration device of the self-retracting type since
this can result in additional free fall for which the system was not
designed. Any substitution or change to a personal fall arrest system
should be fully evaluated or tested by a competent person to determine
that it meets the
[[Page 178]]
standard, before the modified system is put in use.
(d) Employee training considerations. Thorough employee training in
the selection and use of personal fall arrest systems is imperative. As
stated in the standard, before the equipment is used, employees must be
trained in the safe use of the system. This should include the
following: Application limits; proper anchoring and tie-off techniques;
estimation of free fall distance, including determination of
deceleration distance, and total fall distance to prevent striking a
lower level; methods of use; and inspection and storage of the system.
Careless or improper use of the equipment can result in serious injury
or death. Employers and employees should become familiar with the
material in this appendix, as well as manufacturer's recommendations,
before a system is used. Of uppermost importance is the reduction in
strength caused by certain tie-offs (such as using knots, tying around
sharp edges, etc.) and maximum permitted free fall distance. Also, to be
stressed are the importance of inspections prior to use, the limitations
of the equipment, and unique conditions at the worksite which may be
important in determining the type of system to use.
(e) Instruction considerations. Employers should obtain
comprehensive instructions from the supplier as to the system's proper
use and application, including, where applicable:
(1) The force measured during the sample force test;
(2) The maximum elongation measured for lanyards during the force
test;
(3) The deceleration distance measured for deceleration devices
during the force test;
(4) Caution statements on critical use limitations;
(5) Application limits;
(6) Proper hook-up, anchoring and tie-off techniques, including the
proper dee-ring or other attachment point to use on the body belt and
harness for fall arrest;
(7) Proper climbing techniques;
(8) Methods of inspection, use, cleaning, and storage; and
(9) Specific lifelines which may be used. This information should be
provided to employees during training.
(f) Inspection considerations. As stated in the standard (section I,
Paragraph (f)), personal fall arrest systems must be regularly
inspected. Any component with any significant defect, such as cuts,
tears, abrasions, mold, or undue stretching; alterations or additions
which might affect its efficiency; damage due to deterioration; contact
with fire, acids, or other corrosives; distorted hooks or faulty hook
springs; tongues unfitted to the shoulder of buckles; loose or damaged
mountings; non-functioning parts; or wearing or internal deterioration
in the ropes must be withdrawn from service immediately, and should be
tagged or marked as unusable, or destroyed.
(g) Rescue considerations. As required by the standard (section I,
Paragraph (e)(8)), when personal fall arrest systems are used, the
employer must assure that employees can be promptly rescued or can
rescue themselves should a fall occur. The availability of rescue
personnel, ladders or other rescue equipment should be evaluated. In
some situations, equipment which allows employees to rescue themselves
after the fall has been arrested may be desirable, such as devices which
have descent capability.
(h) Tie-off considerations. (1) One of the most important aspects of
personal fall protection systems is fully planning the system before it
is put into use. Probably the most overlooked component is planning for
suitable anchorage points. Such planning should ideally be done before
the structure or building is constructed so that anchorage points can be
incorporated during construction for use later for window cleaning or
other building maintenance. If properly planned, these anchorage points
may be used during construction, as well as afterwards.
(2) Employers and employees should at all times be aware that the
strength of a personal fall arrest system is based on its being attached
to an anchoring system which does not significantly reduce the strength
of the system (such as a properly dimensioned eye-bolt/snap-hook
anchorage). Therefore, if a means of attachment is used that will reduce
the strength of the system, that component should be replaced by a
stronger one, but one that will also maintain the appropriate maximum
arrest force characteristics.
(3) Tie-off using a knot in a rope lanyard or lifeline (at any
location) can reduce the lifeline or lanyard strength by 50 percent or
more. Therefore, a stronger lanyard or lifeline should be used to
compensate for the weakening effect of the knot, or the lanyard length
should be reduced (or the tie-off location raised) to minimize free fall
distance, or the lanyard or lifeline should be replaced by one which has
an appropriately incorporated connector to eliminate the need for a
knot.
(4) Tie-off of a rope lanyard or lifeline around an ``H'' or ``I''
beam or similar support can reduce its strength as much as 70 percent
due to the cutting action of the beam edges. Therefore, use should be
made of a webbing lanyard or wire core lifeline around the beam; or the
lanyard or lifeline should be protected from the edge; or free fall
distance should be greatly minimized.
(5) Tie-off where the line passes over or around rough or sharp
surfaces reduces strength drastically. Such a tie-off should be avoided
or an alternative tie-off rigging should be used. Such alternatives may
include use of a snap-hook/dee ring connection, wire rope tie-off, an
effective padding of the
[[Page 179]]
surfaces, or an abrasion-resistance strap around or over the problem
surface.
(6) Horizontal lifelines may, depending on their geometry and angle
of sag, be subjected to greater loads than the impact load imposed by an
attached component. When the angle of horizontal lifeline sag is less
than 30 degrees, the impact force imparted to the lifeline by an
attached lanyard is greatly amplified. For example, with a sag angle of
15 degrees, the force amplification is about 2:1 and at 5 degrees sag,
it is about 6:1. Depending on the angle of sag, and the line's
elasticity, the strength of the horizontal lifeline and the anchorages
to which it is attached should be increased a number of times over that
of the lanyard. Extreme care should be taken in considering a horizontal
lifeline for multiple tie-offs. The reason for this is that in multiple
tie-offs to a horizontal lifeline, if one employee falls, the movement
of the falling employee and the horizontal lifeline during arrest of the
fall may cause other employees to also fall. Horizontal lifeline and
anchorage strength should be increased for each additional employee to
be tied-off. For these and other reasons, the design of systems using
horizontal lifelines must only be done by qualified persons. Testing of
installed lifelines and anchors prior to use is recommended.
(7) The strength of an eye-bolt is rated along the axis of the bolt
and its strength is greatly reduced if the force is applied at an angle
to this axis (in the direction of shear). Also, care should be exercised
in selecting the proper diameter of the eye to avoid accidental
disengagement of snap-hooks not designed to be compatible for the
connection.
(8) Due to the significant reduction in the strength of the
lifeline/lanyard (in some cases, as much as a 70 percent reduction), the
sliding hitch knot should not be used for lifeline/lanyard connections
except in emergency situations where no other available system is
practical. The ``one-and-one'' sliding hitch knot should never be used
because it is unreliable in stopping a fall. The ``two-and-two,'' or
``three-and-three'' knot (preferable), may be used in emergency situa-
tions; however, care should be taken to limit free fall distance to a
minimum because of reduced lifeline/lanyard strength.
(i) Vertical lifeline considerations. As required by the standard,
each employee must have a separate lifeline when the lifeline is
vertical. The reason for this is that in multiple tie-offs to a single
lifeline, if one employee falls, the movement of the lifeline during the
arrest of the fall may pull other employees' lanyards, causing them to
fall as well.
(j) Snap-hook considerations. Although not required by this standard
for all connections, locking snap-hooks designed for connection to
suitable objects (of sufficient strength) are highly recommended in lieu
of the non-locking type. Locking snap-hooks incorporate a positive
locking mechanism in addition to the spring loaded keeper, which will
not allow the keeper to open under moderate pressure without someone
first releasing the mechanism. Such a feature, properly designed,
effectively prevents roll-out from occurring.
As required by the standard (section I, paragraph (e)(1)) the
following connections must be avoided (unless properly designed locking
snap-hooks are used) because they are conditions which can result in
roll-out when a nonlocking snap-hook is used:
Direct connection of a snap-hook to a horizontal
lifeline.
Two (or more) snap-hooks connected to one dee-
ring.
Two snap-hooks connected to each other.
A snap-hook connected back on its integral
lanyard.
A snap-hook connected to a webbing loop or
webbing lanyard.
Improper dimensions of the dee-ring, rebar, or
other connection point in relation to the snap-hook dimensions which
would allow the snap-hook keeper to be depressed by a turning motion of
the snap-hook.
(k) Free fall considerations. The employer and employee should at
all times be aware that a system's maximum arresting force is evaluated
under normal use conditions established by the manufacturer, and in no
case using a free fall distance in excess of six feet (1.8 m). A few
extra feet of free fall can significantly increase the arresting force
on the employee, possibly to the point of causing injury. Because of
this, the free fall distance should be kept at a minimum, and, as
required by the standard, in no case greater than six feet (1.8 m). To
help assure this, the tie-off attachment point to the lifeline or anchor
should be located at or above the connection point of the fall arrest
equipment to belt or harness. (Since otherwise additional free fall
distance is added to the length of the connecting means (i.e. lanyard)).
Attaching to the working surface will often result in a free fall
greater than six feet (1.8 m). For instance, if a six foot (1.8 m)
lanyard is used, the total free fall distance will be the distance from
the working level to the body belt (or harness) attachment point plus
the six feet (1.8 m) of lanyard length. Another important consideration
is that the arresting force which the fall system must withstand also
goes up with greater distances of free fall, possibly exceeding the
strength of the system.
(l) Elongation and deceleration distance considerations. Other
factors involved in a proper tie-off are elongation and deceleration
distance. During the arresting of a fall, a lanyard will experience a
length of stretching or elongation, whereas activation of a deceleration
device will result in a certain stopping distance. These distances
should be available
[[Page 180]]
with the lanyard or device's instructions and must be added to the free
fall distance to arrive at the total fall distance before an employee is
fully stopped. The additional stopping distance may be very significant
if the lanyard or deceleration device is attached near or at the end of
a long lifeline, which may itself add considerable distance due to its
own elongation. As required by the standard, sufficient distance to
allow for all of these factors must also be maintained between the
employee and obstructions below, to prevent an injury due to impact
before the system fully arrests the fall. In addition, a minimum of 12
feet (3.7 m) of lifeline should be allowed below the securing point of a
rope grab type deceleration device, and the end terminated to prevent
the device from sliding off the lifeline. Alternatively, the lifeline
should extend to the ground or the next working level below. These
measures are suggested to prevent the worker from inadvertently moving
past the end of the lifeline and having the rope grab become disengaged
from the lifeline.
(m) Obstruction considerations. The location of the tie-off should
also consider the hazard of obstructions in the potential fall path of
the employee. Tie-offs which minimize the possibilities of exaggerated
swinging should be considered. In addition, when a body belt is used,
the employee's body will go through a horizontal position to a jack-
knifed position during the arrest of all falls. Thus, obstructions which
might interfere with this motion should be avoided or a severe injury
could occur.
(n) Other considerations. Because of the design of some personal
fall arrest systems, additional considerations may be required for
proper tie-off. For example, heavy deceleration devices of the self-
retracting type should be secured overhead in order to avoid the weight
of the device having to be supported by the employee. Also, if
selfretracting equipment is connected to a horizontal lifeline, the sag
in the lifeline should be minimized to prevent the device from sliding
down the lifeline to a position which creates a swing hazard during fall
arrest. In all cases, manufacturer's instructions should be followed.

August 27, 1971, but no later than [insert date, 180 days after the
effective date], shall meet all of the design, construction and
installation requirements of Part II and III of the ``American National
Standard Safety Requirements for Powered Platforms for Exterior Building
Maintenance ANSI A120.1-1970'' and of this appendix. References shall be
made to appropriate parts of ANSI A120.1-1970 for detail specifications
for equipment and special installations.
(2) Limitation. The requirements of this appendix apply only to
electric powered platforms. It is not the intent of this appendix to
prohibit the use of other types of power. Installation of powered
platforms using other types of power is permitted, provided such
platforms have adequate protective devices for the type of power used,
and otherwise provide for reasonable safety of life and limb to users of
equipment and to others who may be exposed.
(3) Types of powered platforms. (i) For the purpose of applying this
appendix, powered platforms are divided into two basic types, Type F and
Type T.
(ii) Powered platforms designated as Type F shall meet all the
requirements in Part II of ANSI A 120.1-1970, American National Standard
Safety Requirements for Powered Platforms for Exterior Building
Maintenance. A basic requirement of Type F equipment is that the work
platform is suspended by at least four wire ropes and designed so that
failure of any one wire rope will not substantially alter the normal
position of the working platform. Another basic requirement of Type F
equipment is that only one layer of hoisting rope is permitted on
winding drums. Type F powered platforms may be either roof-powered or
self-powered.
(iii) Powered platforms designated as Type T shall meet all the
requirements in Part III of ANSI A120.1-1970 American National Standard
Safety Requirements for Powered Platforms for Exterior Building
Maintenance, except for section 28, Safety Belts and Life Lines. A basic
requirement of Type T equipment is that the working platform is
suspended by at least two wire ropes. Failure of one wire rope would not
permit the working platform to fall to the ground, but would upset its
normal position. Type T powered
[[Page 182]]
platforms may be either roof-powered or self-powered.
(iv) The requirements of this section apply to powered platforms
with winding drum type hoisting machines. It is not the intent of this
section to prohibit powered platforms using other types of hoisting
machines such as, but not limited to, traction drum hoisting machines,
air powered machines, hydraulic powered machines, and internal
combustion machines. Installation of powered platforms with other types
of hoisting machines is permitted, provided adequate protective devices
are used, and provided reasonable safety of life and limb to users of
the equipment and to others who may be exposed is assured.
(v) Both Type F and Type T powered platforms shall comply with the
requirements of appendix C of this standard.
(c) Type F powered platforms--(1) Roof car, general. (i) A roof car
shall be provided whenever it is necessary to move the working platform
horizontally to working or storage positions.
(ii) The maximum rated speed at which a power traversed roof car may
be moved in a horizontal direction shall be 50 feet per minute.
(2) Movement and positioning of roof car. (i) Provision shall be
made to protect against having the roof car leave the roof or enter roof
areas not designed for travel.
(ii) The horizontal motion of the roof cars shall be positively
controlled so as to insure proper movement and positioning of the roof
car.
(iii) Roof car positioning devices shall be provided to insure that
the working platform is placed and retained in proper position for
vertical travel and during storage.
(iv) Mechanical stops shall be provided to prevent the traversing of
the roof car beyond its normal limits of travel. Such stops shall be
capable of withstanding a force equal to 100 percent of the inertial
effect of the roof car in motion with traversing power applied.
(v)(a) The operating device of a power-operated roof car for
traversing shall be located on the roof car, the working platform, or
both, and shall be of the continuous pressure weather-proof electric
type. If more than one operating device is provided, they shall be so
arranged that traversing is possible only from one operating device at a
time.

Standard Fundamentals Governing the Design and Operation of Local
Exhaust Systems, Z9.2-1960.
(ii) Exhaust systems for grinding, polishing, and buffing operations
shall be tested in the manner described in American Standard
Fundamentals Governing the Design and Operation of Local Exhaust
Systems, Z9.2-1960.
[[Page 198]]
(iii) All exhaust systems shall be provided with suitable dust
collectors.
(5) Hood and enclosure design. (i)(a) It is the dual function of
grinding and abrasive cutting-off wheel hoods to protect the operator
from the hazards of bursting wheels as well as to provide a means for
the removal of dust and dirt generated. All hoods shall be not less in
structural strength than specified in the American National Standard
Safety Code for the Use, Care, and Protection of Abrasive Wheels, B7.1-
1970, which is incorporated by reference as specified in Sec. 1910.6.
(b) Due to the variety of work and types of grinding machines
employed, it is necessary to develop hoods adaptable to the particular
machine in question, and such hoods shall be located as close as
possible to the operation.
(ii) Exhaust hoods for floor stands, pedestals, and bench grinders
shall be designed in accordance with figure G-2. The adjustable tongue
shown in the figure shall be kept in working order and shall be adjusted
within one-fourth inch of the wheel periphery at all times.
(iii) Swing-frame grinders shall be provided with exhaust booths as
indicated in figure G-3.
(iv) Portable grinding operations, whenever the nature of the work
permits, shall be conducted within a partial enclosure. The opening in
the enclosure shall be no larger than is actually required in the
operation and an average face air velocity of not less than 200 feet per
minute shall be maintained.
(v) Hoods for polishing and buffing and scratch-brush wheels shall
be constructed to conform as closely to figure G-4 as the nature of the
work will permit.
(vi) Cradle grinding and polishing operations shall be performed
within a partial enclosure similar to figure G-5. The operator shall be
positioned outside the working face of the opening of the enclosure. The
face opening of the enclosure should not be any greater in area than
that actually required for the performance of the operation and the
average air velocity into the working face of the enclosure shall not be
less than 150 feet per minute.
(vii) Hoods for horizontal single-spindle disc grinders shall be
constructed to conform as closely as possible to the hood shown in
figure G-6. It is essential that there be a space between the back of
the wheel and the hood, and a space around the periphery of the wheel of
at least 1 inch in order to permit the suction to act around the wheel
periphery. The opening on the side of the disc shall be no larger than
is required for the grinding operation, but must never be less than
twice the area of the branch outlet.
(viii) Horizontal double-spindle disc grinders shall have a hood
encircling the wheels and grinding chamber similar to that illustrated
in figure G-7. The openings for passing the work into the grinding
chamber should be kept as small as possible, but must never be less than
twice the area of the branch outlets.
(ix) Vertical-spindle disc grinders shall be encircled with a hood
so constructed that the heavy dust is drawn off a surface of the disc
and the lighter dust exhausted through a continuous slot at the top of
the hood as shown in figure G-1.
(x) Grinding and polishing belt hoods shall be constructed as close
to the operation as possible. The hood should extend almost to the belt,
and 1-inch wide openings should be provided on either side. Figure G-8
shows a typical hood for a belt operation.

Notes:
(1) Attention is invited to the fact that the effectiveness of the spray booth is dependent upon the
relationship of the depth of the booth to its height and width.
[[Page 209]]
(2) Crossdrafts can be eliminated through proper design and such design should be sought. Crossdrafts in excess
of 100fpm (feet per minute) should not be permitted.
(3) Excessive air pressures result in loss of both efficiency and material waste in addition to creating a
backlash that may carry overspray and fumes into adjacent work areas.
(4) Booths should be designed with velocities shown in the column headed ``Design.'' However, booths operating
with velocities shown in the column headed ``Range'' are in compliance with this standard.
(ii) In addition to the requirements in paragraph (c)(6)(i) of this
section the total air volume exhausted through a spray booth shall be
such as to dilute solvent vapor to at least 25 percent of the lower
explosive limit of the solvent being sprayed. An example of the method
of calculating this volume is given below.
Example: To determine the lower explosive limits of the most common
solvents used in spray finishing, see Table G-11. Column 1 gives the
number of cubic feet of vapor per gallon of solvent and column 2 gives
the lower explosive limit (LEL) in percentage by volume of air. Note
that the quantity of solvent will be diminished by the quantity of
solids and nonflammables contained in the finish.
To determine the volume of air in cubic feet necessary to dilute the
vapor from 1 gallon of solvent to 25 percent of the lower explosive
limit, apply the following formula:
Dilution volume required per gallon of solvent = 4 (100-LEL) (cubic feet
of vapor per gallon)/ LEL
Using toluene as the solvent.
(1) LEL of toluene from Table G-11, column 2, is 1.4 percent.
(2) Cubic feet of vapor per gallon from Table G-11, column 1, is
30.4 cubic feet per gallon.
(3) Dilution volume required=
4 (100-1.4) 30.4/ 1.4 = 8,564 cubic feet.
(4) To convert to cubic feet per minute of required ventilation,
multiply the dilution volume required per gallon of solvent by the
number of gallons of solvent evaporated per minute.

(ii) Where a spray booth or room receives make-up air through self-
closing doors, dampers, or louvers, they shall be fully open at all
times when the booth or room is in use for spraying. The velocity of air
through such doors, dampers, or louvers shall not exceed
[[Page 210]]
200 feet per minute. If the fan characteristics are such that the
required air flow through the booth will be provided, higher velocities
through the doors, dampers, or louvers may be used.
(iii)(a) Where the air supply to a spray booth or room is filtered,
the fan static pressure shall be calculated on the assumption that the
filters are dirty to the extent that they require cleaning or
replacement.
(b) The rating of filters shall be governed by test data supplied by
the manufacturer of the filter. A pressure gage shall be installed to
show the pressure drop across the filters. This gage shall be marked to
show the pressure drop at which the filters require cleaning or
replacement. Filters shall be replaced or cleaned whenever the pressure
drop across them becomes excessive or whenever the air flow through the
face of the booth falls below that specified in Table G-10.
(iv)(a) Means for heating make-up air to any spray booth or room,
before or at the time spraying is normally performed, shall be provided
in all places where the outdoor temperature may be expected to remain
below 55 [deg]F. for appreciable periods of time during the operation of
the booth except where adequate and safe means of radiant heating for
all operating personnel affected is provided. The replacement air during
the heating seasons shall be maintained at not less than 65 [deg]F. at
the point of entry into the spray booth or spray room. When otherwise
unheated make-up air would be at a temperature of more than 10 [deg]F.
below room temperature, its temperature shall be regulated as provided
in section 3.6.3 of ANSI Z9.2-1960.
(b) As an alternative to an air replacement system complying with
the preceding section, general heating of the building in which the
spray room or booth is located may be employed provided that all
occupied parts of the building are maintained at not less than 65
[deg]F. when the exhaust system is in operation or the general heating
system supplemented by other sources of heat may be employed to meet
this requirement.
(c) No means of heating make-up air shall be located in a spray
booth.
(d) Where make-up air is heated by coal or oil, the products of
combustion shall not be allowed to mix with the make-up air, and the
products of combustion shall be conducted outside the building through a
flue terminating at a point remote from all points where make-up air
enters the building.
(e) Where make-up air is heated by gas, and the products of
combustion are not mixed with the make-up air but are conducted through
an independent flue to a point outside the building remote from all
points where make-up air enters the building, it is not necessary to
comply with paragraph (c)(7)(iv)(f) of this section.
(f) Where make-up air to any manually operated spray booth or room
is heated by gas and the products of combustion are allowed to mix with
the supply air, the following precautions must be taken:
(1) The gas must have a distinctive and strong enough odor to warn
workmen in a spray booth or room of its presence if in an unburned state
in the make-up air.
(2) The maximum rate of gas supply to the make-up air heater burners
must not exceed that which would yield in excess of 200 p.p.m. (parts
per million) of carbon monoxide or 2,000 p.p.m. of total combustible
gases in the mixture if the unburned gas upon the occurrence of flame
failure were mixed with all of the make-up air supplied.
(3) A fan must be provided to deliver the mixture of heated air and
products of combustion from the plenum chamber housing the gas burners
to the spray booth or room.
(8) Scope. Spray booths or spray rooms are to be used to enclose or
confine all spray finishing operations covered by this paragraph (c).
This paragraph does not apply to the spraying of the exteriors of
buildings, fixed tanks, or similar structures, nor to small portable
spraying apparatus not used repeatedly in the same location.

Sec. 1910.95 Occupational noise exposure.
(a) Protection against the effects of noise exposure shall be
provided when the sound levels exceed those shown in Table G-16 when
measured on the A scale of a standard sound level meter at slow
response. When noise levels are determined by octave band analysis, the
equivalent A-weighted sound level may be determined as follows:
[GRAPHIC] [TIFF OMITTED] TC27OC91.023
Figure G-9
Equivalent sound level contours. Octave band sound pressure levels may
be converted to the equivalent A-weighted sound level by plotting them
on this graph and noting the A-weighted sound level corresponding to the
point of highest penetration into the sound level contours. This
equivalent A-weighted sound level, which may differ from the actual A-
weighted sound level of the noise, is used to determine exposure limits
from Table 1.G-16.
(b)(1) When employees are subjected to sound exceeding those listed
in Table G-16, feasible administrative or engineering controls shall be
utilized. If such controls fail to reduce sound levels within the levels
of Table G-16, personal protective equipment shall be provided and used
to reduce sound levels within the levels of the table.
(2) If the variations in noise level involve maxima at intervals of
1 second or less, it is to be considered continuous.

\1\ When the daily noise exposure is composed of two or more periods of
noise exposure of different levels, their combined effect should be
considered, rather than the individual effect of each. If the sum of
the following fractions: C1/T1+C2/T2Cn/Tn exceeds unity, then, the
mixed exposure should be considered to exceed the limit value. Cn
indicates the total time of exposure at a specified noise level, and
Tn indicates the total time of exposure permitted at that level.
Exposure to impulsive or impact noise should not exceed 140 dB peak
sound pressure level.
(c) Hearing conservation program. (1) The employer shall administer
a continuing, effective hearing conservation program, as described in
paragraphs (c) through (o) of this section, whenever employee noise
exposures equal or exceed an 8-hour time-weighted average sound level
(TWA) of 85 decibels measured on the A scale (slow response) or,
equivalently, a dose of fifty percent. For purposes of the hearing
conservation program, employee noise exposures shall be computed in
accordance with appendix A and Table G-16a, and without regard to any
attenuation provided by the use of personal protective equipment.
(2) For purposes of paragraphs (c) through (n) of this section, an
8-hour time-weighted average of 85 decibels or a dose of fifty percent
shall also be referred to as the action level.
(d) Monitoring. (1) When information indicates that any employee's
exposure may equal or exceed an 8-hour time-weighted average of 85
decibels, the employer shall develop and implement a monitoring program.
(i) The sampling strategy shall be designed to identify employees
for inclusion in the hearing conservation program and to enable the
proper selection of hearing protectors.
(ii) Where circumstances such as high worker mobility, significant
variations
[[Page 212]]
in sound level, or a significant component of impulse noise make area
monitoring generally inappropriate, the employer shall use
representative personal sampling to comply with the monitoring
requirements of this paragraph unless the employer can show that area
sampling produces equivalent results.
(2)(i) All continuous, intermittent and impulsive sound levels from
80 decibels to 130 decibels shall be integrated into the noise
measurements.
(ii) Instruments used to measure employee noise exposure shall be
calibrated to ensure measurement accuracy.
(3) Monitoring shall be repeated whenever a change in production,
process, equipment or controls increases noise exposures to the extent
that:
(i) Additional employees may be exposed at or above the action
level; or
(ii) The attenuation provided by hearing protectors being used by
employees may be rendered inadequate to meet the requirements of
paragraph (j) of this section.
(e) Employee notification. The employer shall notify each employee
exposed at or above an 8-hour time-weighted average of 85 decibels of
the results of the monitoring.
(f) Observation of monitoring. The employer shall provide affected
employees or their representatives with an opportunity to observe any
noise measurements conducted pursuant to this section.
(g) Audiometric testing program. (1) The employer shall establish
and maintain an audiometric testing program as provided in this
paragraph by making audiometric testing available to all employees whose
exposures equal or exceed an 8-hour time-weighted average of 85
decibels.
(2) The program shall be provided at no cost to employees.
(3) Audiometric tests shall be performed by a licensed or certified
audiologist, otolaryngologist, or other physician, or by a technician
who is certified by the Council of Accreditation in Occupational Hearing
Conservation, or who has satisfactorily demonstrated competence in
administering audiometric examinations, obtaining valid audiograms, and
properly using, maintaining and checking calibration and proper
functioning of the audiometers being used. A technician who operates
microprocessor audiometers does not need to be certified. A technician
who performs audiometric tests must be responsible to an audiologist,
otolaryngologist or physician.
(4) All audiograms obtained pursuant to this section shall meet the
requirements of appendix C: Audiometric Measuring Instruments.
(5) Baseline audiogram. (i) Within 6 months of an employee's first
exposure at or above the action level, the employer shall establish a
valid baseline audiogram against which subsequent audiograms can be
compared.
(ii) Mobile test van exception. Where mobile test vans are used to
meet the audiometric testing obligation, the employer shall obtain a
valid baseline audiogram within 1 year of an employee's first exposure
at or above the action level. Where baseline audiograms are obtained
more than 6 months after the employee's first exposure at or above the
action level, employees shall wearing hearing protectors for any period
exceeding six months after first exposure until the baseline audiogram
is obtained.
(iii) Testing to establish a baseline audiogram shall be preceded by
at least 14 hours without exposure to workplace noise. Hearing
protectors may be used as a substitute for the requirement that baseline
audiograms be preceded by 14 hours without exposure to workplace noise.
(iv) The employer shall notify employees of the need to avoid high
levels of non-occupational noise exposure during the 14-hour period
immediately preceding the audiometric examination.
(6) Annual audiogram. At least annually after obtaining the baseline
audiogram, the employer shall obtain a new audiogram for each employee
exposed at or above an 8-hour time-weighted average of 85 decibels.
(7) Evaluation of audiogram. (i) Each employee's annual audiogram
shall be compared to that employee's baseline audiogram to determine if
the audiogram is valid and if a standard threshold shift as defined in
paragraph (g)(10)
[[Page 213]]
of this section has occurred. This comparison may be done by a
technician.
(ii) If the annual audiogram shows that an employee has suffered a
standard threshold shift, the employer may obtain a retest within 30
days and consider the results of the retest as the annual audiogram.
(iii) The audiologist, otolaryngologist, or physician shall review
problem audiograms and shall determine whether there is a need for
further evaluation. The employer shall provide to the person performing
this evaluation the following information:
(A) A copy of the requirements for hearing conservation as set forth
in paragraphs (c) through (n) of this section;
(B) The baseline audiogram and most recent audiogram of the employee
to be evaluated;
(C) Measurements of background sound pressure levels in the
audiometric test room as required in appendix D: Audiometric Test Rooms.
(D) Records of audiometer calibrations required by paragraph (h)(5)
of this section.
(8) Follow-up procedures. (i) If a comparison of the annual
audiogram to the baseline audiogram indicates a standard threshold shift
as defined in paragraph (g)(10) of this section has occurred, the
employee shall be informed of this fact in writing, within 21 days of
the determination.
(ii) Unless a physician determines that the standard threshold shift
is not work related or aggravated by occupational noise exposure, the
employer shall ensure that the following steps are taken when a standard
threshold shift occurs:
(A) Employees not using hearing protectors shall be fitted with
hearing protectors, trained in their use and care, and required to use
them.
(B) Employees already using hearing protectors shall be refitted and
retrained in the use of hearing protectors and provided with hearing
protectors offering greater attenuation if necessary.
(C) The employee shall be referred for a clinical audiological
evaluation or an otological examination, as appropriate, if additional
testing is necessary or if the employer suspects that a medical
pathology of the ear is caused or aggravated by the wearing of hearing
protectors.
(D) The employee is informed of the need for an otological
examination if a medical pathology of the ear that is unrelated to the
use of hearing protectors is suspected.
(iii) If subsequent audiometric testing of an employee whose
exposure to noise is less than an 8-hour TWA of 90 decibels indicates
that a standard threshold shift is not persistent, the employer:
(A) Shall inform the employee of the new audiometric interpretation;
and
(B) May discontinue the required use of hearing protectors for that
employee.
(9) Revised baseline. An annual audiogram may be substituted for the
baseline audiogram when, in the judgment of the audiologist,
otolaryngologist or physician who is evaluating the audiogram:
(i) The standard threshold shift revealed by the audiogram is
persistent; or
(ii) The hearing threshold shown in the annual audiogram indicates
significant improvement over the baseline audiogram.
(10) Standard threshold shift. (i) As used in this section, a
standard threshold shift is a change in hearing threshold relative to
the baseline audiogram of an average of 10 dB or more at 2000, 3000, and
4000 Hz in either ear.
(ii) In determining whether a standard threshold shift has occurred,
allowance may be made for the contribution of aging (presbycusis) to the
change in hearing level by correcting the annual audiogram according to
the procedure described in appendix F: Calculation and Application of
Age Correction to Audiograms.
(h) Audiometric test requirements. (1) Audiometric tests shall be
pure tone, air conduction, hearing threshold examinations, with test
frequencies including as a minimum 500, 1000, 2000, 3000, 4000, and 6000
Hz. Tests at each frequency shall be taken separately for each ear.
(2) Audiometric tests shall be conducted with audiometers (including
microprocessor audiometers) that meet
[[Page 214]]
the specifications of, and are maintained and used in accordance with,
American National Standard Specification for Audiometers, S3.6-1969,
which is incorporated by reference as specified in Sec. 1910.6.
(3) Pulsed-tone and self-recording audiometers, if used, shall meet
the requirements specified in appendix C: Audiometric Measuring
Instruments.
(4) Audiometric examinations shall be administered in a room meeting
the requirements listed in appendix D: Audiometric Test Rooms.
(5) Audiometer calibration. (i) The functional operation of the
audiometer shall be checked before each day's use by testing a person
with known, stable hearing thresholds, and by listening to the
audiometer's output to make sure that the output is free from distorted
or unwanted sounds. Deviations of 10 decibels or greater require an
acoustic calibration.
(ii) Audiometer calibration shall be checked acoustically at least
annually in accordance with appendix E: Acoustic Calibration of
Audiometers. Test frequencies below 500 Hz and above 6000 Hz may be
omitted from this check. Deviations of 15 decibels or greater require an
exhaustive calibration.
(iii) An exhaustive calibration shall be performed at least every
two years in accordance with sections 4.1.2; 4.1.3.; 4.1.4.3; 4.2;
4.4.1; 4.4.2; 4.4.3; and 4.5 of the American National Standard
Specification for Audiometers, S3.6-1969. Test frequencies below 500 Hz
and above 6000 Hz may be omitted from this calibration.

available to all employees exposed to an 8-hour time-weighted average of
85 decibels or greater at no cost to the employees. Hearing protectors
shall be replaced as necessary.
(2) Employers shall ensure that hearing protectors are worn:
(i) By an employee who is required by paragraph (b)(1) of this
section to wear personal protective equipment; and
(ii) By any employee who is exposed to an 8-hour time-weighted
average of 85 decibels or greater, and who:
(A) Has not yet had a baseline audiogram established pursuant to
paragraph (g)(5)(ii); or
(B) Has experienced a standard threshold shift.
(3) Employees shall be given the opportunity to select their hearing
protectors from a variety of suitable hearing protectors provided by the
employer.

hearing protector attenuation for the specific noise environments in
which the protector will be used. The employer shall use one of the
evaluation methods described in appendix B: Methods for Estimating the
Adequacy of Hearing Protection Attenuation.
(2) Hearing protectors must attenuate employee exposure at least to
an 8-hour time-weighted average of 90 decibels as required by paragraph
(b) of this section.
(3) For employees who have experienced a standard threshold shift,
hearing protectors must attenuate employee exposure to an 8-hour time-
weighted average of 85 decibels or below.
(4) The adequacy of hearing protector attenuation shall be re-
evaluated whenever employee noise exposures increase to the extent that
the hearing protectors provided may no longer provide adequate
attenuation. The employer shall provide more effective hearing
protectors where necessary.
(k) Training program. (1) The employer shall institute a training
program for all employees who are exposed to noise at or above an 8-hour
time-weighted average of 85 decibels, and shall ensure employee
participation in such program.

Appendix A to Sec. 1910.95--Noise Exposure Computation
This Appendix is Mandatory
I. Computation of Employee Noise Exposure
(1) Noise dose is computed using Table G-16a as follows:
(i) When the sound level, L, is constant over the entire work shift,
the noise dose, D, in percent, is given by: D=100 C/T where C is the
total length of the work day, in hours, and T is the reference duration
corresponding to the measured sound level, L, as given in Table G-16a or
by the formula shown as a footnote to that table.
(ii) When the workshift noise exposure is composed of two or more
periods of noise at different levels, the total noise dose over the work
day is given by:
D=100(C1/T1+C2/
T2+Cn/Tn),
where Cn indicates the total time of exposure at a specific
noise level, and Tn indicates the reference duration for that
level as given by Table G-16a.
(2) The eight-hour time-weighted average sound level (TWA), in
decibels, may be computed from the dose, in percent, by means of the
formula: TWA=16.61 log10 (D/100)+90. For an eight-hour
workshift with the noise level constant over the entire shift, the TWA
is equal to the measured sound level.
[[Page 216]]
(3) A table relating dose and TWA is given in Section II.

where L is the measured A-weighted sound level.
II. Conversion Between ``Dose'' and ``8-Hour Time-Weighted Average''
Sound Level
Compliance with paragraphs (c)-(r) of this regulation is determined
by the amount of exposure to noise in the workplace. The amount of such
exposure is usually measured with an audiodosimeter which gives a
readout in terms of ``dose.'' In order to better understand the
requirements of the amendment, dosimeter readings can be converted to an
``8-hour time-weighted average sound level.'' (TWA).
In order to convert the reading of a dosimeter into TWA, see Table
A-1, below. This table applies to dosimeters that are set by the
manufacturer to calculate dose or percent exposure according to the
relationships in Table G-16a. So, for example, a dose of 91 percent over
an eight hour day results in a TWA of 89.3 dB, and, a dose of 50 percent
corresponds to a TWA of 85 dB.
If the dose as read on the dosimeter is less than or greater than
the values found in Table A-1, the TWA may be calculated by using the
formula: TWA=16.61 log10 (D/100)+90 where TWA=8-hour time-
weighted average sound level and D=accumulated dose in percent exposure.

Appendix B to Sec. 1910.95--Methods for Estimating the Adequacy of
Hearing Protector Attenuation
This Appendix is Mandatory
For employees who have experienced a significant threshold shift,
hearing protector attenuation must be sufficient to reduce employee
exposure to a TWA of 85 dB. Employers must select one of the following
methods by which to estimate the adequacy of hearing protector
attenuation.
The most convenient method is the Noise Reduction Rating (NRR)
developed by the Environmental Protection Agency (EPA).
[[Page 218]]
According to EPA regulation, the NRR must be shown on the hearing
protector package. The NRR is then related to an individual worker's
noise environment in order to assess the adequacy of the attenuation of
a given hearing protector. This appendix describes four methods of using
the NRR to determine whether a particular hearing protector provides
adequate protection within a given exposure environment. Selection among
the four procedures is dependent upon the employer's noise measuring
instruments.
Instead of using the NRR, employers may evaluate the adequacy of
hearing protector attenuation by using one of the three methods
developed by the National Institute for Occupational Safety and Health
(NIOSH), which are described in the ``List of Personal Hearing
Protectors and Attenuation Data,'' HEW Publication No. 76-120, 1975,
pages 21-37. These methods are known as NIOSH methods 1B1,
1B2 and 1B3. The NRR described below is a
simplification of NIOSH method 1B2. The most complex method is
NIOSH method 1B1, which is probably the most accurate method
since it uses the largest amount of spectral information from the
individual employee's noise environment. As in the case of the NRR
method described below, if one of the NIOSH methods is used, the
selected method must be applied to an individual's noise environment to
assess the adequacy of the attenuation. Employers should be careful to
take a sufficient number of measurements in order to achieve a
representative sample for each time segment.
Note: The employer must remember that calculated attenuation values
reflect realistic values only to the extent that the protectors are
properly fitted and worn.
When using the NRR to assess hearing protector adequacy, one of the
following methods must be used:
(i) When using a dosimeter that is capable of C-weighted
measurements:
(A) Obtain the employee's C-weighted dose for the entire workshift,
and convert to TWA (see appendix A, II).
(B) Subtract the NRR from the C-weighted TWA to obtain the estimated
A-weighted TWA under the ear protector.
(ii) When using a dosimeter that is not capable of C-weighted
measurements, the following method may be used:
(A) Convert the A-weighted dose to TWA (see appendix A).
(B) Subtract 7 dB from the NRR.
(C) Subtract the remainder from the A-weighted TWA to obtain the
estimated A-weighted TWA under the ear protector.
(iii) When using a sound level meter set to the A-weighting network:
(A) Obtain the employee's A-weighted TWA.
(B) Subtract 7 dB from the NRR, and subtract the remainder from the
A-weighted TWA to obtain the estimated A-weighted TWA under the ear
protector.
(iv) When using a sound level meter set on the C-weighting network:
(A) Obtain a representative sample of the C-weighted sound levels in
the employee's environment.
(B) Subtract the NRR from the C-weighted average sound level to
obtain the estimated A-weighted TWA under the ear protector.
(v) When using area monitoring procedures and a sound level meter
set to the A-weighing network.
(A) Obtain a representative sound level for the area in question.
(B) Subtract 7 dB from the NRR and subtract the remainder from the
A-weighted sound level for that area.
(vi) When using area monitoring procedures and a sound level meter
set to the C-weighting network:
(A) Obtain a representative sound level for the area in question.
(B) Subtract the NRR from the C-weighted sound level for that area.
Appendix C to Sec. 1910.95--Audiometric Measuring Instruments
This Appendix is Mandatory
1. In the event that pulsed-tone audiometers are used, they shall
have a tone on-time of at least 200 milliseconds.
2. Self-recording audiometers shall comply with the following
requirements:
(A) The chart upon which the audiogram is traced shall have lines at
positions corresponding to all multiples of 10 dB hearing level within
the intensity range spanned by the audiometer. The lines shall be
equally spaced and shall be separated by at least \1/4\ inch. Additional
increments are optional. The audiogram pen tracings shall not exceed 2
dB in width.
(B) It shall be possible to set the stylus manually at the 10-dB
increment lines for calibration purposes.
(C) The slewing rate for the audiometer attenuator shall not be more
than 6 dB/sec except that an initial slewing rate greater than 6 dB/sec
is permitted at the beginning of each new test frequency, but only until
the second subject response.
(D) The audiometer shall remain at each required test frequency for
30 seconds ( 3 seconds). The audiogram shall be
clearly marked at each change of frequency and the actual frequency
change of the audiometer shall not deviate from the frequency boundaries
marked on the audiogram by more than 3 seconds.
(E) It must be possible at each test frequency to place a horizontal
line segment parallel to the time axis on the audiogram, such that the
audiometric tracing crosses the line segment at least six times at that
test frequency. At each test frequency the
[[Page 219]]
threshold shall be the average of the midpoints of the tracing
excursions.
Appendix D to Sec. 1910.95--Audiometric Test Rooms
This Appendix is Mandatory
Rooms used for audiometric testing shall not have background sound
pressure levels exceeding those in Table D-1 when measured by equipment
conforming at least to the Type 2 requirements of American National
Standard Specification for Sound Level Meters, S1.4-1971 (R1976), and to
the Class II requirements of American National Standard Specification
for Octave, Half-Octave, and Third-Octave Band Filter Sets, S1.11-1971
(R1976).

------------------------------------------------------------------------
Appendix E to Sec. 1910.95--Acoustic Calibration of Audiometers
This Appendix is Mandatory
Audiometer calibration shall be checked acoustically, at least
annually, according to the procedures described in this appendix. The
equipment necessary to perform these measurements is a sound level
meter, octave-band filter set, and a National Bureau of Standards 9A
coupler. In making these measurements, the accuracy of the calibrating
equipment shall be sufficient to determine that the audiometer is within
the tolerances permitted by American Standard Specification for
Audiometers, S3.6-1969.
(1) Sound Pressure Output Check
A. Place the earphone coupler over the microphone of the sound level
meter and place the earphone on the coupler.
B. Set the audiometer's hearing threshold level (HTL) dial to 70 dB.
C. Measure the sound pressure level of the tones at each test
frequency from 500 Hz through 6000 Hz for each earphone.
D. At each frequency the readout on the sound level meter should
correspond to the levels in Table E-1 or Table E-2, as appropriate, for
the type of earphone, in the column entitled ``sound level meter
reading.''
(2) Linearity Check
A. With the earphone in place, set the frequency to 1000 Hz and the
HTL dial on the audiometer to 70 dB.
B. Measure the sound levels in the coupler at each 10-dB decrement
from 70 dB to 10 dB, noting the sound level meter reading at each
setting.
C. For each 10-dB decrement on the audiometer the sound level meter
should indicate a corresponding 10 dB decrease.
D. This measurement may be made electrically with a voltmeter
connected to the earphone terminals.
(3) Tolerances
When any of the measured sound levels deviate from the levels in
Table E-1 or Table E-2 by 3 dB at any test
frequency between 500 and 3000 Hz, 4 dB at 4000 Hz, or 5 dB at 6000 Hz,
an exhaustive calibration is advised. An exhaustive calibration is
required if the deviations are greater than 15 dB or greater at any test
frequency.

Appendix F to Sec. 1910.95--Calculations and Application of Age
Corrections to Audiograms
This Appendix Is Non-Mandatory
In determining whether a standard threshold shift has occurred,
allowance may be made for the contribution of aging to the change in
hearing level by adjusting the most recent audiogram. If the employer
chooses to adjust the audiogram, the employer shall follow the procedure
described below. This procedure and the age correction tables were
developed by the National Institute for Occupational Safety and Health
in the criteria document entitled ``Criteria for a Recommended Standard
. . . Occupational Exposure to Noise,'' ((HSM)-11001).
For each audiometric test frequency;
[[Page 220]]
(i) Determine from Tables F-1 or F-2 the age correction values for
the employee by:
(A) Finding the age at which the most recent audiogram was taken and
recording the corresponding values of age corrections at 1000 Hz through
6000 Hz;
(B) Finding the age at which the baseline audiogram was taken and
recording the corresponding values of age corrections at 1000 Hz through
6000 Hz.
(ii) Subtract the values found in step (i)(B) from the value found
in step (i)(A).
(iii) The differences calculated in step (ii) represented that
portion of the change in hearing that may be due to aging.
Example: Employee is a 32-year-old male. The audiometric history for
his right ear is shown in decibels below.
------------------------------------------------------------------------
Audiometric test frequency (Hz)

30.............................. 0 5 10 20 10
31.............................. 5 10 20 15 15
*32............................. 5 10 10 25 20
------------------------------------------------------------------------
The audiogram at age 27 is considered the baseline since it shows
the best hearing threshold levels. Asterisks have been used to identify
the baseline and most recent audiogram. A threshold shift of 20 dB
exists at 4000 Hz between the audiograms taken at ages 27 and 32.
(The threshold shift is computed by subtracting the hearing
threshold at age 27, which was 5, from the hearing threshold at age 32,
which is 25). A retest audiogram has confirmed this shift. The
contribution of aging to this change in hearing may be estimated in the
following manner:
Go to Table F-1 and find the age correction values (in dB) for 4000
Hz at age 27 and age 32.
------------------------------------------------------------------------
Frequency (Hz)
---------------------------------------
1000 2000 3000 4000 6000
------------------------------------------------------------------------
Age 32.......................... 6 5 7 10 14
Age 27.......................... 5 4 6 7 11
---------------------------------------
Difference.................. 1 1 1 3 3
------------------------------------------------------------------------
The difference represents the amount of hearing loss that may be
attributed to aging in the time period between the baseline audiogram
and the most recent audiogram. In this example, the difference at 4000
Hz is 3 dB. This value is subtracted from the hearing level at 4000 Hz,
which in the most recent audiogram is 25, yielding 22 after adjustment.
Then the hearing threshold in the baseline audiogram at 4000 Hz (5) is
subtracted from the adjusted annual audiogram hearing threshold at 4000
Hz (22). Thus the age-corrected threshold shift would be 17 dB (as
opposed to a threshold shift of 20 dB without age correction).

Appendix G to Sec. 1910.95--Monitoring Noise Levels Non-Mandatory
Informational Appendix
This appendix provides information to help employers comply with the
noise monitoring obligations that are part of the hearing conservation
amendment.
What is the purpose of noise monitoring?
This revised amendment requires that employees be placed in a
hearing conservation program if they are exposed to average noise levels
of 85 dB or greater during an 8 hour workday. In order to determine if
exposures are at or above this level, it may be necessary to measure or
monitor the actual noise levels in the workplace and to estimate the
noise exposure or ``dose'' received by employees during the workday.
When is it necessary to implement a noise monitoring program?
It is not necessary for every employer to measure workplace noise.
Noise monitoring or measuring must be conducted only when exposures are
at or above 85 dB. Factors which suggest that noise exposures in the
workplace may be at this level include employee complaints about the
loudness of noise, indications that employees are losing their hearing,
or noisy conditions which make normal conversation difficult. The
employer should also consider any information available regarding noise
emitted from specific machines. In addition, actual workplace noise
measurements can suggest whether or not a monitoring program should be
initiated.
How is noise measured?
Basically, there are two different instruments to measure noise
exposures: the sound level meter and the dosimeter. A sound level meter
is a device that measures the intensity of sound at a given moment.
Since sound level meters provide a measure of sound intensity at only
one point in time, it is generally necessary to take a number of
measurements at different times during the day to estimate noise
exposure over a workday. If noise levels fluctuate, the amount of time
noise remains at each of the various measured levels must be determined.
To estimate employee noise exposures with a sound level meter it is
also generally necessary to take several measurements at different
locations within the workplace. After appropriate sound level meter
readings are obtained, people sometimes draw ``maps'' of the sound
levels within different areas of the workplace. By using a sound level
``map'' and information on employee locations throughout the day,
estimates of individual exposure levels can be developed. This
measurement method is generally referred to as area noise monitoring.
A dosimeter is like a sound level meter except that it stores sound
level measurements and integrates these measurements over time,
providing an average noise exposure reading for a given period of time,
such as an 8-hour workday. With a dosimeter, a microphone is attached to
the employee's clothing and the exposure measurement is simply read at
the end of the desired time period. A reader may be used to read-out the
dosimeter's measurements. Since the dosimeter is worn by the employee,
it measures noise levels in those locations in which the employee
travels. A sound level meter can also be positioned within the immediate
vicinity of the exposed worker to obtain an individual exposure
estimate. Such procedures are generally referred to as personal noise
monitoring.
Area monitoring can be used to estimate noise exposure when the
noise levels are relatively constant and employees are not mobile. In
workplaces where employees move about in different areas or where the
noise intensity tends to fluctuate over time, noise exposure is
generally more accurately estimated by the personal monitoring approach.
In situations where personal monitoring is appropriate, proper
positioning of the microphone is necessary to obtain accurate
measurements. With a dosimeter, the microphone is generally located on
the shoulder and remains in that position for the entire workday. With a
sound level meter, the microphone is stationed near the employee's head,
and the instrument is usually held by an individual who follows the
employee as he or she moves about.
Manufacturer's instructions, contained in dosimeter and sound level
meter operating manuals, should be followed for calibration
[[Page 222]]
and maintenance. To ensure accurate results, it is considered good
professional practice to calibrate instruments before and after each
use.
How often is it necessary to monitor noise levels?
The amendment requires that when there are significant changes in
machinery or production processes that may result in increased noise
levels, remonitoring must be conducted to determine whether additional
employees need to be included in the hearing conservation program. Many
companies choose to remonitor periodically (once every year or two) to
ensure that all exposed employees are included in their hearing
conservation programs.
Where can equipment and technical advice be obtained?
Noise monitoring equipment may be either purchased or rented. Sound
level meters cost about $500 to $1,000, while dosimeters range in price
from about $750 to $1,500. Smaller companies may find it more economical
to rent equipment rather than to purchase it. Names of equipment
suppliers may be found in the telephone book (Yellow Pages) under
headings such as: ``Safety Equipment,'' ``Industrial Hygiene,'' or
``Engineers-Acoustical.'' In addition to providing information on
obtaining noise monitoring equipment, many companies and individuals
included under such listings can provide professional advice on how to
conduct a valid noise monitoring program. Some audiological testing
firms and industrial hygiene firms also provide noise monitoring
services. Universities with audiology, industrial hygiene, or acoustical
engineering departments may also provide information or may be able to
help employers meet their obligations under this amendment.
Free, on-site assistance may be obtained from OSHA-supported state
and private consultation organizations. These safety and health
consultative entities generally give priority to the needs of small

Appendix I to Sec. 1910.95--Definitions
These definitions apply to the following terms as used in paragraphs
(c) through (n) of 29 CFR 1910.95.
Action level--An 8-hour time-weighted average of 85 decibels measured on
the A-scale, slow response, or equivalently, a dose of fifty percent.
Audiogram--A chart, graph, or table resulting from an audiometric test
showing an individual's hearing threshold levels as a function of
frequency.
Audiologist--A professional, specializing in the study and
rehabilitation of hearing, who is certified by the American Speech-
Language-Hearing Association or licensed by a state board of examiners.
Baseline audiogram--The audiogram against which future audiograms are
compared.
[[Page 223]]
Criterion sound level--A sound level of 90 decibels.
Decibel (dB)--Unit of measurement of sound level.
Hertz (Hz)--Unit of measurement of frequency, numerically equal to
cycles per second.
Medical pathology--A disorder or disease. For purposes of this
regulation, a condition or disease affecting the ear, which should be
treated by a physician specialist.
Noise dose--The ratio, expressed as a percentage, of (1) the time
integral, over a stated time or event, of the 0.6 power of the measured
SLOW exponential time-averaged, squared A-weighted sound pressure and
(2) the product of the criterion duration (8 hours) and the 0.6 power of
the squared sound pressure corresponding to the criterion sound level
(90 dB).
Noise dosimeter--An instrument that integrates a function of sound
pressure over a period of time in such a manner that it directly
indicates a noise dose.
Otolaryngologist--A physician specializing in diagnosis and treatment of
disorders of the ear, nose and throat.
Representative exposure--Measurements of an employee's noise dose or 8-
hour time-weighted average sound level that the employers deem to be
representative of the exposures of other employees in the workplace.
Sound level--Ten times the common logarithm of the ratio of the square
of the measured A-weighted sound pressure to the square of the standard
reference pressure of 20 micropascals. Unit: decibels (dB). For use with
this regulation, SLOW time response, in accordance with ANSI S1.4-1971
(R1976), is required.
Sound level meter--An instrument for the measurement of sound level.
Time-weighted average sound level--That sound level, which if constant
over an 8-hour exposure, would result in the same noise dose as is
measured.

Sec. 1910.97 Nonionizing radiation.
(a) Electromagnetic radiation--(1) Definitions applicable to this
paragraph. (i) The term electromagnetic radiation is restricted to that
portion of the spectrum commonly defined as the radio frequency region,
which for the purpose of this specification shall include the microwave
frequency region.
(ii) Partial body irradiation. Pertains to the case in which part of
the body is exposed to the incident electromagnetic energy.
(iii) Radiation protection guide. Radiation level which should not
be exceeded without careful consideration of the reasons for doing so.
(iv) The word ``symbol'' as used in this specification refers to the
overall design, shape, and coloring of the rf radiation sign shown in
figure G-11.
(v) Whole body irradiation. Pertains to the case in which the entire
body is exposed to the incident electromagnetic energy or in which the
cross section of the body is smaller than the cross section of the
incident radiation beam.
(2) Radiation protection guide. (i) For normal environmental
conditions and for incident electromagnetic energy of frequencies from
10 MHz to 100 GHz, the radiation protection guide is 10 mW/cm.\2\
(milliwatt per square centimeter) as averaged over any possible 0.1-hour
period. This means the following:
Power density: 10 mW./cm.\2\ for periods of 0.1-hour or more.
Energy density: 1 mW.-hr./cm.\2\ (milliwatt hour per square centimeter)
during any 0.1-hour period.
This guide applies whether the radiation is continuous or intermittent.
(ii) These formulated recommendations pertain to both whole body
irradiation and partial body irradiation. Partial body irradiation must
be included since it has been shown that some parts of the human body
(e.g., eyes, testicles) may be harmed if exposed to incident radiation
levels significantly in excess of the recommended levels.
(3) Warning symbol. (i) The warning symbol for radio frequency
radiation hazards shall consist of a red isosceles triangle above an
inverted black isosceles triangle, separated and outlined by an aluminum
color border. The words ``Warning--Radio-Frequency Radiation Hazard''
shall appear in the upper triangle. See figure G-11.
(ii) American National Standard Safety Color Code for Marking
Physical Hazards and the Identification of Certain Equipment, Z53.1-
1953, which is incorporated by reference as specified in Sec. 1910.6,
shall be used for color specification. All lettering and the border
shall be of aluminum color.
[[Page 224]]
(iii) The inclusion and choice of warning information or
precautionary instructions is at the discretion of the user. If such
information is included it shall appear in the lower triangle of the
warning symbol.

(4) Scope. This section applies to all radiations originating from
radio stations, radar equipment, and other possible sources of
electromagnetic radiation such as used for communication, radio
navigation, and industrial and scientific purposes. This section does
not apply to the deliberate exposure of patients by, or under the
direction of, practitioners of the healing arts.
