Request for Information About Diethanolamine (CAS No. 111-42-2)
AGENCY: National Institute for Occupational Safety and Health (NIOSH)
of the Centers for Disease Control and Prevention (CDC), Department of
Health and Human Services (HHS).
ACTION: Request for information.
-----------------------------------------------------------------------
SUMMARY: The National Institute for Occupational Safety and Health
(NIOSH) of the Centers for Disease Control and Prevention (CDC) intends
to evaluate the scientific data on diethanolamine, and develop
appropriate communication documents, such as a Criteria Document, which
will convey the potential health risks, recommended measures for safe
handling, and establish an updated Recommended Exposure Limit (REL).
The current NIOSH REL for diethanolamine is 3 parts per million (ppm)
as a time-weighted average (TWA) concentration for up to a 10-hr work
shift during a 40-hr workweek.
NIOSH is requesting information on the following: (1) Published and
unpublished reports and findings from in vitro and in vivo toxicity
studies with diethanolamine; (2) information on possible health effects
observed in workers exposed to diethanolamine, including exposure data
and the method(s) used for sampling and analyzing exposures; (3)
description of work tasks and scenarios with a potential for exposure
to diethanolamine; (4) information on control measures (e.g.
engineering controls, work practices, personal protective equipment,
exposure data before and after implementation of control measures) that
are being used in workplaces with potential exposure to diethanolamine;
and (5) surveillance findings including protocol, methods, and results.
Public Comment Period: Comments must be received by June 24, 2013.
ADDRESSES: You may submit comments, identified by CDC-2013-0005 and
Docket Number NIOSH-263, by either of the two following methods:
Federal eRulemaking Portal: http://www.regulations.gov.
Follow the instructions for submitting comments.
Mail: NIOSH Docket Office, Robert A. Taft Laboratories,
MS-C34, 4676 Columbia Parkway, Cincinnati, OH 45226.
Instructions: All information received in response to this notice
must include the agency name and docket number (CDC-2013-0005; NIOSH-
263). All relevant comments received will be posted without change to
http://www.regulations.gov, including any personal information
provided. All electronic comments should be formatted as Microsoft
Word. Please make reference to CDC-2013-0005 and Docket Number NIOSH-
263.

SUPPLEMENTARY INFORMATION: Diethanolamine is a highly reactive
compound. It decomposes on burning producing toxic fumes.
Diethanolamine reacts violently with oxidants and strong acids.
Diethanolamine is used to produce surface active agents widely used in
soaps, cosmetics and personal care items. It also has other uses
including as an absorbent in gas purification, as a dispersing agent in
agricultural chemicals, a corrosion inhibitor and wetting agent in
metalworking fluids.
The annual production of diethanolamine in the United States was
estimated in 1995 to be 106,000 tons (Technology Planning and
Management Corp, 2002). NIOSH estimates from the National Occupational
Exposure Survey (NIOSH 1989) that the number of workers potentially
exposed to diethanolamine is approximately 830,000/year.
Significant occupational exposures to diethanolamine are through
the skin (dermal) and via inhalation (lung) during the use of
lubricating liquids in various processes in machine building. Chronic
exposure to diethanolamine can cause skin sensitization. Diethanolamine
is also corrosive to the eyes. The current REL for diethanolamine is 3
ppm as a TWA concentration for up to a 10-hr work shift during a 40-hr
workweek. The NIOSH REL was established as a result of testimony
submitted to the Occupational Safety and Health Administration (OSHA)
on their proposed rulemaking of Air Contaminants in 1988. Currently,
concentrations below the REL can be detected and quantified. As part of
an effort to identify RELs that may not be adequate to protect workers
from adverse health effects due to exposure, NIOSH is reexamining the
REL for diethanolamine. There is no OSHA permissible exposure limit
(PEL) for diethanolamine. The American Conference of Governmental
Hygienists (ACGIH[supreg]) threshold limit value (TLV[supreg])--TWA for
diethanolamine is 1 mg/m\3\ (inhalable fraction and vapor), with a Skin
notation (indicating danger of cutaneous absorption), and an A3
carcinogenicity classification (confirmed animal carcinogen with
unknown relevance to humans).
NIOSH seeks to obtain materials, including published and
unpublished reports and research findings, to evaluate the possible
health risks of occupational exposure to diethanolamine. Examples of
requested information include, but are not limited to, the following:
(1) Identification of industries or occupations in which exposures
to diethanolamine may occur.
(2) Trends in the production and use of diethanolamine.
(3) Description of work tasks and scenarios with a potential for
exposure to diethanolamine.
(4) Workplace exposure measurement data of diethanolamine in
various types of industries and jobs.
(5) Case reports or other health information demonstrating
potential health effects in workers exposed to diethanolamine.
(6) Research findings from in vitro and in vivo studies.
(7) Information on control measures (e.g., engineering controls,
work practices, PPE) being taken to minimize worker exposure to
diethanolamine.
(8) Educational materials for worker safety and training on the
safe handling of diethanolamine.
(9) Data pertaining to the feasibility of establishing a more
protective REL for diethanolamine.
(10) Names of substitute chemicals or processes being used in place
of diethanolamine and type of work tasks.
