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, October 1, 2004), 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.
INCORPORATION BY REFERENCE
What is incorporation by reference? Incorporation by reference was
established by statute and allows Federal agencies to meet the
requirement to publish regulations in the Federal Register by referring
to materials already published elsewhere. For an incorporation to be
valid, the Director of the Federal Register must approve it. The legal
effect of incorporation by reference is that the material is treated as
if it were published in full in the Federal Register (5 U.S.C. 552(a)).
This material, like any other properly issued regulation, has the force
of law.
What is a proper incorporation by reference? The Director of the
Federal Register will approve an incorporation by reference only when
the requirements of 1 CFR part 51 are met. Some of the elements on which
approval is based are:
(a) The incorporation will substantially reduce the volume of
material published in the Federal Register.
(b) The matter incorporated is in fact available to the extent
necessary to afford fairness and uniformity in the administrative
process.
(c) The incorporating document is drafted and submitted for
publication in accordance with 1 CFR part 51.
Properly approved incorporations by reference in this volume are
listed in the Finding Aids at the end of this volume.
What if the material incorporated by reference cannot be found? If
you have any problem locating or obtaining a copy of material listed in
the Finding Aids of this volume as an approved incorporation by
reference, please contact the agency that issued the regulation
containing that incorporation. If, after contacting the agency, you find
the material is not available, please notify the Director of the Federal
Register, National Archives and Records Administration, Washington DC
20408, or call (202) 741-6010.
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.

Sec. 150.130 Loading a cargo on vessels carrying cargoes with which it
is incompatible.
Except as described in Sec. 150.160, the person in charge of a
vessel shall ensure that the containment system for a cargo that is a
hazardous material meets the following requirements:
(a) The containment system must separate the hazardous material or
its residue from any cargo in table I with which it is incompatible by
two barriers such as formed by a:
(1) Cofferdam;
(2) Empty tank;
(3) Void space;
(4) Cargo handling space;
(5) Tank containing a compatible cargo; or
(6) Piping tunnel.
(b) In this subpart, isolation across a cruciform joint is
equivalent to isolation by two barriers.
(c) The containment system for the hazardous material must not have
a piping or venting system that connects to a containment system
carrying a cargo with which the hazardous material is incompatible. Any
such piping or venting system must have been separated from the
containment system carrying the incompatible cargo by:
(1) Removing a valve or spool piece and blanking off the exposed
pipe ends, or
(2) Installing two spectacle flanges in series with a means of
detecting leakage into the pipe between the spectacle flanges.
Sec. 150.140 Cargoes not listed in Table I or II.
A cargo of hazardous material not listed in Table I or II must be
handled as if incompatible with all other cargoes until the Commandant
(G-MSO) (tel. no. (202) 267-1577) assigns the hazardous material to a
compatibility group. (Table I lists cargoes alphabetically while Table
II lists cargoes by compatibility group).

Sec. 150.150 Exceptions to the compatibility chart.
The Commandant (G-MSO) authorizes, on a case by case basis,
exceptions to the rules in this subpart under the following conditions:
(a) When two cargoes shown to be incompatible in Figure 1 meet the
standards for a compatible pair in Appendix III, or
(b) When two cargoes shown to be compatible in Figure 1 meet the
standards for an incompatible pair in Appendix III.
Appendix I contains cargoes which have been found to be exceptions
to Figure 1, the Compatibility Chart.

Sec. 150.160 Carrying a cargo as an exception to the compatibility chart.
The Operator of a vessel having on board a cargo carried as an
exception under Sec. 150.150 but not listed in Appendix I, Exceptions
to the Chart, shall make sure that:
(a) The Commandant (G-MSO) has authorized by letter or message the
cargo pair as an exception to the compatibility chart; and
(b) A copy of the letter or message is on the vessel.

Appendix II to Part 150--Explanation of Figure 1
Definition of a hazardous reaction-- As a first approximation, a
mixture of two cargoes is considered hazardous when, under specified
condition, the temperature rise of the mixture exceeds 25 [deg]C or a
gas is evolved. It is possible for the reaction of two cargoes to
produce a product that is significantly more flammable or toxic than the
original cargoes even though the reaction is non-hazardous from
temperature or pressure considerations, although no examples of such a
reaction are known at this time.
Chart format-- There are different degrees of reactivity among the
various cargoes. Many of them are relatively non-reactive: For example,
aromatic hydrocarbons or paraffins. Others will form hazardous
combinations with many groups: For example, the inorganic acids.
The cargo groups in the compatibility chart are separated into two
categories: 1 through 22 are ``Reactive Groups'' and 30 through 43 are
``Cargo Groups''. Left unassigned and available for future expansion are
groups 23 through 29 and those past 43. Reactive Groups contain products
which are chemically the most reactive; dangerous combinations may
result between members of different Reactive Groups and between members
of Reactive Groups and Cargo Groups. Products assigned to Cargo Groups,
however, are much less reactive; dangerous combinations involving these
can be formed only with members of certain Reactive Groups. Cargo Groups
do not react hazardously with one another.
Using the Compatibility Chart-- The following procedure explains how
the compatibility chart should be used to find compatibility infomation:
(1) Determine the group numbers of the two cargoes by referring to
the alphabetical listing of cargoes and the corresponding groups (Table
I). Many cargoes are listed under their parent names; unless otherwise
[[Page 55]]
indicated, isomers or mixtures of isomers of a particular cargo are
assigned to the same group. For example, to find the group number for
Isobutyl Alcohol, look under the parent name Butyl Alcohol. Similarly,
the group number for para-Xylene is found under the entry Xylene. If a
cargo cannot be found in this listing, contact the Coast Guard for a
group determination (see Sec. 150.140).
(2) If both group numbers are between 30 and 43 inclusive, the
products are compatible and the chart need not be used.
(3) If both group numbers do not fall between 30 and 43 inclusive,
locate one of the numbers on the left of the chart (Cargo Groups) and
the other across the top (Reactive Groups). (Note that if a group number
is between 30 and 43, it can only be found on the left side of the
chart.) The box formed by the intersection of the column and row
containing the two numbers will contain one of the following:
(a) Blank--The two cargoes are compatible.
(b) ``X''--The two cargoes are not compatible.
(Note that reactivity may vary among the group members. Refer to Table I
or Table II to find whether the products in question are referenced by a
footnote which indicates that exceptions exist and are listed in
Appendix I. Unless the combination is specifically mentioned in Appendix
I, it is compatible.)

Appendix III to Part 150--Testing Procedures for Determining Exceptions
to the Chart
experimental procedure for evaluating binary chemical reactivity
General safety precautions--Chemical reactivity tests have, by their
nature, serious potential for injuring the experimenter or destroying
equipment. The experimenter should 1) have knowledge of the magnitude of
the reactivity to be expected, 2) use adequate facilities and protective
equipment to prevent injury from splatter of materials or release of
fumes, and 3) start on a small scale so that unexpected reactions can be
safely contained. All tests should be performed in a well-ventilated
laboratory hood provided with shields.
Testing chemicals other than liquids--The procedure outlined below
was developed for chemicals which are liquids at ambient temperatures.
If one or both chemicals are normally shipped at elevated temperatures,
the same procedure may be followed except the chemicals are tested at
their respective shipping temperatures and the oil bath in Step 3 is
maintained at a level 25 [deg]C above the higher temperature. This
information is then indicated on the data sheet. If one of the chemicals
is a gas at ambient temperatures, consult the Coast Guard for additional
instructions before proceeding with the compatibility test.
Step 1
Objective--To determine if the test chemicals react violently and
present a safety hazard in further tests.
Procedure--Place 0.5ml of one (A) of the test chemicals in a
25x150mm test tube. Clamp the test tube to a stand behind a safety
shield (in a hood). Carefully add from a dropper 0.5ml of the other
substance (B). Shake to induce mixing. If no immediate reaction occurs,
retain the mixture for at least 10 minutes to check for a delayed
reaction.
Results--If a violent reaction occurs, such as sputtering, boiling
of reactants or release of fumes, record the results on the Data Sheet
(appendix IV) and do not proceed to Step 2. If no reaction or a minor
reaction occurs, proceed to Step 2.
Step 2
Objective--To determine the heat of reaction of two chemicals on
mixing under specified conditions.
Procedure--These separate mixes of the proposed binary combination
will be tested. These are 2 ml : 18 ml, 10 ml : 10 ml, and 18 ml : 2 ml,
respectively, to result in a final mixture of about 20 ml in each case.
A reference-junctioned thermocouple is prepared by inserting two
lengths of 20 gauge or finer iron-constantan or chromelalumel duplex
thermocouple wire into glass capilary sheaths. The common wire of each
probe is joined, while the other wire of each is connected to a strip-
chart recorder. The thermocouple probe which produces a negative pen
deflection upon warming is the reference junction and is placed in a
test tube of water at ambient laboratory temprature. The other probe is
placed near the bottom of a Dewar flask of about 300ml capacity, such
that the thermocouple will be below the surface of the test mixture. The
Dewar flask is equipped with a magnetic stirrer having a stirring bar
coated with an inert material such as a flourinated hydrocarbon.
Start the temperature recorder and stirrer. Deliver the test
chemicals to the Dewar
[[Page 56]]
Flask simultaneously from separate graduated syringes. If an exothermic
reaction occurs, continue the test until the maximum temperature is
reached and begins to subside. If no apparent reaction occurs, continue
the test for at least 30 minutes to check for a delayed reaction. Stop
agitation and observe the mixture at five-minute intervals to determine
if the mixture is miscible, if gases are evolved, or if other visible
changes occur. In the interest of safety, a mirror can be used for these
observations. Repeat the above test for the other mixture combinations.
Results--Record the results in the appropriate places on the Data
Sheet. If no reaction occurs or if the temperature rise is less than 25
[deg]C, proceed to Step 3. If the observed temperature rise exceeds 25
[deg]C or gases are evolved, do not proceed to Step 3.
Step 3
Objective--To determine if exothermic reactions occur at
temperatures up to 50 [deg]C.
Procedure--If a non-hazardous reaction occurred in Step 2, the ratio
of chemicals which resulted in the greatest temperature rise will be
tested. Fresh chemicals will be used with a total volume for this test
of about 10ml (a ratio of 1ml:9ml, 5ml:5ml, or 9ml:1ml). If no reaction
was observed in Step 2, use a ratio of 5ml:5ml. Using the thermocouple
prepared for Step 2, insert the reference probe into a 25x150mm test
tube containing 10ml of water. Place the other probe into an empty test
tube. Start the temperature recorder and add the two chemicals of the
combination, one at a time, to the empty test tube. Lower the two test
tubes into an oil bath maintained at 50 2 [deg]C.
Hold the samples in the oil bath until the maximum temperature
differential is recorded, and in all cases at least 15 minutes. Observe
the test mixture to determine if gases are evolved or if other visible
changes occur. Follow prescribed safety precautions.
Results--Record the maximum differential temperature measured, the
time required to reach this temperature, and any other observations in
the proper space on the Data Sheet.
Send a copy of the Data Sheet for each binary chemical mixture
tested to: Commandant (G-MSO), U.S. Coast Guard, Washington, DC 20593-
0001.

owner shall conduct nondestructive testing of each tank designated by
the Officer in Charge, Marine Inspection in accordance with Sec.
151.04-7.
(e) If the Officer in Charge, Marine Inspection considers a
hydrostatic test necessary to determine the condition of the tanks, the
owner shall perform the test at a pressure of 1\1/2\ times the tank's--
(1) Maximum allowable pressure, as determined by the safety relief
valve setting; or
(2) Design pressure, when cargo tanks operate at maximum allowable
pressures reduced below the design pressure in order to satisfy special
mechanical stress relief requirements.
Note: See the ASME Code, Section VIII, Appendix 3 for information on
design pressure.
(f) Quick closing valves shall be tested by operating the emergency
shutoff system from each operating point at the time of each vessel's
inspection for certification.
(g) Excess flow valves shall be inspected at the time of inspection
for certification. The Officer in Charge, Marine Inspection, shall
satisfy himself that the valve is in working condition by visual
inspection, and if this is impossible, by one of the following means:
(1) Removing the valve and bench testing ashore; the valve shall
close at or below its rated closing flow.
(2) By any other means acceptable to the Officer in Charge, Marine
Inspection, which will demonstrate that the valve is operable.
(h) Pressure vaccum relief valves shall be examined to determine
that the operating mechanism is free and capable of activation.
(i) Safety relief valves shall be tested by bench testing or other
suitable means. The valves shall relieve and reseat within the design
tolerances of the set pressure, or it shall be removed and reset prior
to being returned to service. This test shall be conducted at the time
of the inspection for certification.
(j) Cargo hose stored on board the vessel which is used in
transferring cargoes listed in Table 151.05 shall be inspected every 2
years. This inspection shall consist of a visual examination and a
hydrostatic test of 1\1/2\ times the maximum pressure to which the hose
will be subjected in service. The date of the most recent inspection and
the test pressure shall be stenciled or otherwise marked on the hose.
(k) Cargo piping shall be inspected and tested at the same time as
the cargo tanks.
(l) If the tank is a pressure vessel type cargo tank with an
internal inspection interval of 10 years, and is 30 years old or older,
determined from the date it was built, the owner shall conduct
nondestructive testing of each tank in accordance with Sec. 151.04-7,
during each internal inspection.

Sec. 151.04-7 Nondestructive testing.
(a) Before nondestructive testing may be conducted to meet Sec.
151.04-5 (d) and (l), the owner shall submit a proposal to the Officer
in Charge, Marine Inspection that includes--
(1) The test methods and procedures to be used all of which must
meet section V of the ASME Boiler and Pressure Vessel Code (1986);
(2) Each location on the tank to be tested; and
[[Page 67]]
(3) The test method and procedure to be conducted at each location
on the tank.
(b) If the Officer in Charge, Marine Inspection rejects the
proposal, the Officer in Charge, Marine Inspection informs the owner of
the reasons why the proposal is rejected.
(c) If the Officer in Charge, Marine Inspection accepts the
proposal, then the owner shall ensure that--
(1) The proposal is followed; and
(2) Nondestructive testing is performed by personnel meeting ASNT
``Recommended Practice No. SNT-TC-1A (1988), Personnel Qualification and
Certification in Nondestructive Testing.''
(d) Within 30 days after completing the nondestructive test, the
owner shall submit a written report of the results to the Officer in
Charge, Marine Inspection.

Subpart 151.10_Barge Hull Construction Requirements
Sec. 151.10-1 Barge hull classifications.
(a) Each barge constructed or converted in conformance with this
subpart shall be assigned a hull type number.
(1) Effective dates for certain requirements:
(i) Barges constructed or converted between July 1, 1964, and June
1, 1970, in accordance with the construction requirements of Sec. Sec.
32.63 and 98.03 of this chapter are considered to comply with the basic
provisions of this subpart and will retain the hull type classification
for the service for which they were originally approved. Changes in
product endorsement will not be considered a change in service, except
when a change to a product of higher specific gravity necessitates a
reevaluation of the intact and damage stability requirements in subpart
E of part 172 of this chapter.
(2) [Reserved]
(b) For this purpose the barge hull types shall be defined as
follows:
(1) Type I barge hull. Barge hulls classed as Type I are those
designed to carry products which require the maximum preventive measures
to preclude the uncontrolled release of the cargo. These barges are
required to meet:
(i) Standards of intact stability and a modified two compartment

submitted, and upon approval of calculations shall form part of the
endorsement on the Certificate of Inspection:
(1) Limiting draft for each hull type service for which approval is
requested.
(2) Maximum density (lb./gal.) and maximum cargo weight (tons) for
each tank for which approval is requested. Their weights will normally
reflect uniform loading except that for trim purposes the individual
tank cargo weight may exceed the uniform loading tank cargo weight,
corresponding to the barge fresh water deadweight at the limiting draft,
by 5 percent. Where a greater degree of nonuniform loading is desired,
longitudinal strength calculations shall be submitted.

Sec. 151.10-20 Hull construction.
(a) Construction features. (1) Each barge hull shall be constructed
with a suitable bow form (length, shape, and height of headlog) to
protect against diving at the maximum speed at which the barge is
designed to be towed. In
[[Page 93]]
any integrated tow, only the lead barge need comply with this
requirement.
(2) All ``open hopper'' type barges shall be provided with coamings
around the hopper space and a 36-inch minimum height plowshare
breakwater on the forward rake. The plowshare breakwater may be omitted,
if it is demonstrated to the satisfaction of the Commandant that
sufficient protection is achieved without it. Coamings shall have a
minimum height of 36 inches forward and may be graduated to a minimum
height of 24 inches at midlength and 18 inches thereafter. All hopper
barges constructed with a weathertight rain shield over the hopper space
are exempt from these requirements, except that they shall be provided
with an 18-inch minimum coaming all around the hopper.
(3) All ``open hopper'' type barges modified for the carriage of
chlorine in bulk shall be provided with 36-inch minimum height coamings
around the hopper.
(4) All barges in ocean or coastwise service shall be provided with
a structural deck and hatches in accordance with the applicable
provisions of subchapter E of this chapter and the scantling
requirements of the American Bureau of Shipping.
(b) Hull structural requirements. (1) All Types I, II, and III
barges shall comply with the basic structural requirements of the
American Bureau of Shipping for barges of the ordinary types and the
applicable supplementary requirements of this section.
(2) Types I and II barges in inland service: A grounding condition
shall be assumed where the forward rake bulkhead rests upon a pinnacle
at the water surface. The maximum hull and tank bending moment and tank
saddle reactions (if applicable) shall be determined. The hull bending
stress shall not exceed the applicable limits of paragraphs (b)(2) (i),
(ii), or (iii) of this section. The maximum tank bending moment and
saddle reaction shall be used in the tank design calculations required
by Sec. 151.15-2(b)(3).
(i) Independent tanks supported by only two saddles do not
contribute to the strength and stiffness of the barge hull. In such
case, the hull stress shall not exceed either 50 percent of the minimum
ultimate tensile strength of the material or 70 percent of the yield
strength when specified, whichever is greater.
(ii) Independent tanks supported by three or more saddles contribute
to the strength and stiffness of the hull. In such case, the hull stress
shall not exceed the percentage stress values prescribed in Sec.
151.10-20(b)(2)(i), multiplied by the quantity
(1.5-SWT/UTS),
where SWT is the stress calculated without including the effect of the
tanks, and UTS is the minimum ultimate tensile strength of the material.
The value SWT, however, shall in no case be more than 75 percent of UTS.
(iii) Integral tanks may be considered as contributing to the
strength and stiffness of the barge hull. The hull stresses for integral
tank barges shall not exceed the percentage stress values prescribed in
paragraph (b)(2)(i), of this section.
(3) Types I and II barges in ocean service:
(i) Independent tank barges with tanks supported by three or more
saddles shall be subjected to a 0.6L\0.6\ trochoidal wave hogsag
analysis to determine the maximum hull and tank bending moments and tank
saddle reactions.
(ii) All independent tank barges, regardless of the number of saddle
supports shall be subject to a still water bending analysis to determine
the hull bending moment. For those barges with independent tanks
supported by three or more saddles, this analysis shall consider tank-
hull interaction so as to determine tank bending moments and saddle
reactions.
(iii) The still water tank bending moments and saddle reactions
shall be superimposed upon those obtained by simultaneous application of
the following dynamic loadings:
(a) Rolling 30[deg] each side (120[deg] full cycle) in 10 seconds.
(b) Pitching 6[deg] half amplitude (24[deg] full cycle) in 7
seconds.
(c) Heaving L/80 half amplitude (L/20 full cycle) in 8 seconds.
(iv) The hull structure and saddle support system shall be analyzed,
using the maximum hull bending moments and saddle reactions obtained
from the
[[Page 94]]
foregoing. Bending stress shall not exceed 60 percent of the yield
strength or 42 percent of the minimum tensile strength of the material,
whichever is less. Critical buckling strength shall be at least 75
percent greater than calculated buckling stresses. The maximum tank
bending moments and saddle reactions shall be used in the tank design
calculations required by Sec. 151.15-3(b)(8).

(a) The configurations listed in this paragraph refer to the
separation of the cargo from its surroundings and list the various
degrees of segregation required. Paragraphs and (2) of this section
explain the symbols used in lines 1 and 2, in order, under the tank
segregation column of Table 151.05.
(1) Segregation of cargo from surrounding waters (Line 1 of Table
151.05).
i=Skin of vessel (single skin) only required. Cargo tank wall can be
vessel's hull.
ii=Double skin required. Cargo tank wall cannot be vessel's hull.
NA=Nonapplicable for this case. Independent tanks already have such
segregation built in through design.
(2) Segregation of cargo space from machinery spaces and other
spaces which have or could have a source of ignition (Line 2 of Table
151.05).
i=Single bulkhead only required. Tank wall can be sole separating
medium.
ii=Double bulkhead, required. Cofferdam, empty tank, pumproom, tank with
Grade E Liquid (if compatible with cargo) is satisfactory.
(b) [Reserved]
(c) If a cofferdam is required for segregation purposes and a
secondary barrier is required for low temperature protection by Sec.

Subpart 151.15_Tanks
Sec. 151.15-1 Tank types.
This section lists the definitions of the various tank types
required for cargo containment by Table 151.05.
(a) Integral. A cargo containment envelope which forms a part of the
vessel's hull in which it is built, and may be stressed in the same
manner and by the same loads which stress the contiguous hull structure.
An integral tank is essential to the structural completeness of its
vessel's hull.
(b) Independent. A cargo containment envelope which is not a
contiguous part of the hull structure. An independent tank is built and
installed so as to eliminate, wherever possible (or, in any event, to
minimize) its stressing as a result of stressing or motion of the
adjacent hull structure. In general, therefore, motion of parts of the
tank relative to the adjacent hull structure is possible. An independent
tank is not essential to the structural completeness of its carrying
vessel's hull.
(c) Gravity. Tanks having a design pressure (as described in Part 54
of this chapter) not greater than 10 pounds per square inch gauge and of
prismatic shape or other geometry where stress analysis is neither
readily nor completely determinate. (Integral tanks are of the gravity
type.)
(d) Pressure. Independent tanks whose design pressure (as described
in Part 54 of this chapter) is above 10 pounds per square inch gauge and
fabricated in accordance with part 54, of this chapter. Independent
gravity tanks which are of normal pressure vessel configuration (i.e.,
bodies of revolution, in which the stresses are readily determinate)
shall be classed as pressure vessel type tanks even though their maximum
allowable working pressure is less than 10 pounds per square inch gauge.
Pressure vessel tanks shall be of Classes I, I-L, II, II-L, or III, as
defined in subchapter F of this chapter.
Sec. 151.15-3 Construction.
This section lists the requirements for construction of the types of
cargo tanks defined in Sec. 151.15-1.
(a) Gravity type tanks. Gravity type cargo tanks vented at a
pressure of 4 pounds per square inch gauge or less shall be constructed
and tested as required by standards established by the American Bureau
of Shipping or other recognized classification society. Gravity type
tanks vented at a pressure exceeding 4 but not exceeding 10 pounds per
square inch gauge will be given special consideration by the Commandant.
(b) Pressure vessel type tanks. Pressure vessel type tanks shall be
designed and tested in accordance with the requirements of Part 54 of
this chapter.
[[Page 96]]
(1) Uninsulated cargo tanks, where the cargo is transported, at or
near ambient temperatures, shall be designed for a pressure not less
than the vapor pressure of the cargo at 115 [deg]F. The design shall
also be based on the minimum internal pressure (maximum vacuum), plus
the maximum external static head to which the tank may be subjected.
(2) When cargo tanks, in which the cargo is transported at or near
ambient temperature, are insulated with an insulation material of a
thickness to provide a thermal conductance of not more than 0.075 B.t.u.
per square foot per degree Fahrenheit differential in temperature per
hour, the tanks shall be designed for a pressure of not less than the
vapor pressure of the cargo at 105 [deg]F. The insulation shall also
meet the requirements of paragraph (f) of this section.
(3) Cargo tanks in which the temperature is maintained below the
normal atmospheric temperature by refrigeration or other acceptable
means shall be designed for a pressure of not less than 110 percent of
the vapor pressure corresponding to the temperature of the liquid at
which the system is maintained, or the pressure corresponding to the
greatest dynamic and static loads expected to be encountered in service.
For mechanically stressed relieved cargo tanks, additional factors
relating design pressure and maximum allowable pressure shall be as
specified by the Commandant. The material of the tank shall meet the
material requirements specified in part 54 of this chapter for the
service temperature, and this temperature shall be permanently marked on
the tank as prescribed in Sec. 54.10-20 of this chapter.
(4) The maximum allowable temperature of the cargo is defined as the
boiling temperature of the liquid at a pressure equal to the setting of
the relief valve.
(5) The service temperature is the minimum temperature of a product
at which it may be contained, loaded and/or transported. However, the
service temperature shall in no case be taken higher than given by the
following formula.
tz=tw-0.25(tw-tB)
where:
tz=Service temperature.
tw=Boiling temperature of gas at normal working pressure of
container but not higher than +32 [deg]F.
tB=Boiling temperature of gas at atmospheric pressure.
Under normal circumstances, only temperatures due to refrigerated
service will be considered in determining the service temperature.
Refrigerated service for purposes of this paragraph is defined as
service where the temperature is controlled in the process rather than
being caused by atmospheric conditions.
(6) Heat transmission studies, where required, shall assume the
minimum ambient temperatures of 0 [deg]F still air and 32 [deg]F still
water, and maximum ambient temperatures of 115 [deg]F still air and 90
[deg]F still water.
(7) Where applicable, the design of the cargo tanks shall
investigate the thermal stresses induced in the tanks at the service
temperature.
(8) Calculations showing the stress level in the tanks under dynamic
loading conditions for ocean service barges (see Sec. 151.10-20(b)(4))
and grounding conditions for inland service barges (see Sec. 151.10-20-
(b)(2)) shall be submitted to the Commandant for approval. These
calculations shall take into account the local stresses due to the
interaction between the barge hull and the tanks.
(c) High density cargo. Cargoes with a specific gravity greater than
that for which the scantlings of the tank are designed may be carried
provided that:
(1) The maximum cargo weight (tons) in a specific tank does not
exceed the maximum cargo weight (tons) endorsed on the certificate of
inspection.
(2) The scantlings of the tank are sufficient to prevent rupture
under a full head of the higher density cargo. Scantlings meeting
ordinary bulkhead requirements for the full head will satisfy this
requirement.
(d) Arrangements--(1) Collision protection. (i) Tanks containing
cargoes which are required to be carried in Type I hulls by Table 151.05
shall be located a minimum of 4 feet inboard from the side shell and box
end of the vessel. Tanks containing cargoes which are required to be
carried in Type II
[[Page 97]]
hulls by Table 151.05 shall be located a minimum of 3 feet inboard from
the side shell and box end of the vessel.
(ii) All independent cargo tanks installed on Type I or Type II
barge hulls shall be protected with suitable collision chocks or
collision straps. A longitudinal collision load of one and one half
times the combined weight of the tank and the cargo shall be assumed.
All other independent cargo tanks shall be provided with suitable
collision chocks or collision straps assuming a longitudinal collision
load equal to the combined weight of the tank and the cargo. The design
bearing stress shall not exceed 2 times the yield strength or 1.5 times
the minimum ultimate strength, whichever is less.
(iii) Tanks containing cargoes, which are required to be carried in
Type I or Type II hulls by Table 151.05, shall be located a minimum of
25 feet from the head log at the bow. Box barges and trail barges need
not comply with this requirement.
(2) Inspection clearances. The distance between tanks or between a
tank and the vessel's structure shall be such as to provide adequate
access for inspection and maintenance of all tank surfaces and hull
structure; but shall not normally be less than 15 inches except in way
of web frames or similar major structural members where the minimum
clearance shall be equal to the flange or faceplate width.
(3) Access openings. Each tank shall be provided with at least a
15x18 diameter manhole, fitted with a cover
located above the maximum liquid level as close as possible to the top
of the tank. Where access trunks are fitted to tanks, the diameter of
the trunks shall be at least 30 inches.
(4) Low temperature protection. (i) When low temperature cargoes are
to be carried in gravity type tanks at a temperature lower than that for
which the hull steel is adequate, a secondary barrier designed to
contain leaked cargo temporarily shall be provided. The design of the
cargo containment system shall be such that under normal service
conditions, or upon failure of the primary tank, the hull structure
shall not be cooled down to a temperature which is unsafe for the
materials involved. The secondary barrier and structural components of
the hull which may be exposed to low temperatures shall meet the
material requirements (i.e., chemistry and physical properties)
specified in part 54 of this chapter for the service temperature
involved. Heat transmission studies and tests may be required to
demonstrate that the structural material temperatures in the hull are
acceptable.
(ii) The design shall take into consideration the thermal stresses
induced in the cargo tank at the service temperature during loading.
(iii) Where necessary, devices for spray loading or other methods of
precooling or cooling during loading shall be included in the design.
(iv) Pressure-vessel type tanks shall be radiographed in accordance
with the requirements of part 54 of this chapter. For gravity type
tanks, all weld intersections or crossings in joints of primary tank
shells shall be radiographed for a distance of 10 thicknesses from the
intersection. All other welding in the primary tank and in the secondary
barrier, shall be spot radiographed in accordance with the requirements
specified in part 54 of this chapter for Class II-L pressure vessels.
(v) For nonpressure vessel type containment systems, access shall be
arranged to permit inspection one side each of the primary tank and
secondary barrier, under normal shipyard conditions. Containment systems
which, because of their peculiar design, cannot be visually inspected to
this degree, may be specially considered provided an equivalent degree
of safety is attained.
(e) Installation of cargo tanks. (1) Cargo tanks shall be supported
on foundations of steel or other suitable material and securely anchored
in place to prevent the tanks from shifting when subjected to external
forces. Each tank shall be supported so as to prevent the concentration
of excessive loads on the supporting portions of the shell or head.
(2) Foundations, and stays where required, shall be designed for
support and constraint of the weight of the full tank, and the dynamic
loads imposed thereon. Thermal movement shall also be considered.
[[Page 98]]
(3) Foundations and stays shall be suitable for the temperatures
they will experience at design conditions.
(4) Cargo tanks may be installed ``on deck,'' ``under deck,'' or
with the tanks protruding through the deck. All tanks shall be installed
with the manhole openings located in the open above the weather deck.
Provided an equivalent degree of safety is attained, the Commandant may
approve cargo tanks installed with manhole openings located below the
weather deck. Where a portion of the tank extends above the weather
deck, provision shall be made to maintain the weathertightness of the
deck, except that the weathertightness of the upper deck need not be
maintained on:
(i) Vessels operating on restricted routes which are sufficiently
protected; or,
(ii) Open hopper type barges of acceptable design.
(5) No welding shall be performed on tanks which require and have
been stress relieved unless authorized by the Commandant.
(f) Materials. (1) Materials used in the construction of cargo tanks
shall be suitable for the intended application and shall be in
accordance with the applicable requirements of part 54 of this chapter.
For cargoes carried at low temperatures, the tank supports and
foundations, and portions of the hull which may be exposed to low
temperature, shall also meet the applicable requirements of that part.
(2) When required, cargo tanks shall be lined with rubber or other
material acceptable to the Commandant. The interior surfaces of the
cargo tanks shall be made smooth, welds chipped or ground smooth, and
the surfaces thoroughly cleaned before the lining is applied. The lining
material shall be resistive to attack by the cargo, not less elastic
than the metal of the tank proper, and nonporous when tested after
application. It shall be of substantially uniform thickness. The lining
shall be directly bonded to the tank plating, or attached by other
satisfactory means acceptable to the Commandant.
(g) Insulation. (1) Insulation, when provided, shall be compatible
with the cargo and the tank materials.
(2) Insulation in a location exposed to possible high temperature or
source of ignition shall be one of the following:
(i) Incombustible, complying with the requirements of Subpart
164.009 of Part 164 of this chapter; or
(ii) Fire retardant, having a flame spread rating of 50 or less as
determined by ASTM Specification E 84 (incorporated by reference, see
Sec. 151.01-2) (Tunnel Test); or,
(iii) Nonburning or ``self-extinguishing'' as determined by ASTM
Specification D 4986, ``Horizontal Burning Characteristics of Cellular
Polymeric Materials'' (incorporated by reference, see Sec. 151.01-2)
and covered by a steel jacket having a minimum thickness of 18 gauge
(0.0428 inches) (U.S. Standard Gauge) or an equivalent means of
protection acceptable to the Commandant.
(3) Insulation in a location protected against high temperature or
source of ignition need satisfy no requirement for combustibility.
(4) Insulation shall be impervious to water vapor, or have a vapor-
proof coating of a fire-retardant material acceptable to the Commandant.
Unless the vapor barrier is inherently weather resistant, tanks exposed
to the weather shall be fitted with a removable sheet metal jacket of
not less than 18 gauge over the vapor-proof coating and flashed around
all openings so as to be weathertight. Insulation which is not exposed
to the weather when installed on tanks carrying cargoes above ambient
temperatures need not be impervious to water vapor nor be covered with a
vapor-proof coating.
(5) Insulation shall be adequately protected in areas of possible
mechanical damage.
(h) Fire exposure protection. Tanks which are provided with fire
exposure protection of one of the following categories may be allowed a
reduction in the size of relief valves.
(1) Approved incombustible insulation meeting the requirements of
subpart 164.007 of part 164 of this chapter which is secured to the tank
with steel bands.
(2) Located in a hold or protected by a self-supporting steel jacket
or cover (such as a hopper cover) of at least 10 gauge (0.1345) for
insulation.
[[Page 99]]
(i) Tanks not protected against fire exposure as described in this
paragraph shall not be permitted a reduction in size of relief valves.

Sec. 151.15-5 Venting.
This section contains definitions and requirements for the various
methods of venting specified in Table 151.05. In addition to the
requirement that all vents must penetrate into tanks at the top of the
vapor space, the following methods of venting and the applicable
restrictions are listed:
(a) Open venting. A venting system which offers no restriction
(except pipe losses and flame screen, where used) to the movement of
liquid or vapor to or from the cargo tank (via the vent) under normal
operating conditions. The total cross-sectional area of the vents shall
not be less than the total cross-sectional area of the filling pipe or
pipes. Ullage openings may be counted as part of the required cross-
sectional area: Provided, That each cargo tank has at least one
permanent vent. The minimum size of a cargo tank vent shall be not less
than 2\1/2\ inches. The outlet end of the vent shall terminate in a
gooseneck bend and shall be located at a reasonable height above the
weather deck, clear of all obstructions. No shut-off valve or frangible
disk shall be fitted in the vent lines except that a float check valve
may be installed so as to exclude the entry of water into the tank
(i.e., to prevent downflooding). An open venting system may be fitted
with a flame screen.
(b) Pressure-vacuum venting. A normally closed venting system fitted
with a device to automatically limit the pressure or vacuum in the tank
to design limits. Pressure-vacuum relief valves shall comply with the
requirements of subpart 162.017 of this chapter. The required capacity
of the venting system shall be in accordance with part 54 of this
chapter.
(c) Safety relief venting. A closed venting system fitted with a
device to automatically limit the pressure in the tank to below its
maximum allowable working pressure. The maximum safety relief valve
setting shall not exceed the maximum allowable working pressure of the
tank. For cargoes carried at ambient temperatures, the minimum safety
relief valve setting shall correspond to the saturated vapor pressure of
the cargo at 105 [deg]F if carried in an insulated tank, or 115 [deg]F
if carried in an uninsulated tank. For cargoes carried below ambient
temperature, the safety relief valve setting shall be selected to
provide a suitable margin between normal operating pressure of the tank
and the opening pressure of the valve but in no case shall it exceed the
maximum allowable working pressure of the tank. The safety relief valves
shall be of a type approved under subparts 162.001 or 162.018 of
subchapter Q of this chapter. The required capacity of the safety relief
valves shall be in accordance with the requirements of part 54 of this
chapter.

Sec. 151.15-10 Cargo gauging devices.
This section contains definitions and requirements for types of
gauging devices specified in Table 151.05.
(a) Open gauging. A gauging method which uses an opening in the
cargo tank and which may expose the gauge
[[Page 100]]
user to the cargo and its vapors. Examples of this type are gauge hatch,
ullage hole.
(b) Restricted. A gauging device which penetrates the cargo tank and
which, in operation, causes or permits the release to the atmosphere of
small quantities of cargo vapor or liquid. The amount of cargo released
is controlled by the small diameter of the tank penetration opening and
by a locally operated valve or similar closure device in that opening.
When not in use, this type gauging device is closed to maintain the
complete integrity of cargo containment. Examples of this type are
rotary tube, fixed tube, slip tube, sounding tube. (See Sec. Sec.
151.03-43 and 151.15-10(g).)
(c) Closed. A gauging device which penetrates the cargo tank, but
which is part of a closed system maintaining the complete integrity of
cargo containment. This device is designed and installed so as not to
release cargo liquid or vapor in any amount to the atmosphere. Examples
of this type are automatic float, continuous tape (magnetic coupled),
sight glass (protected), electronic probe, magnetic, differential
pressure cell.
(d) Isolated or indirect. A gauging method or device which is
isolated from the tank (no penetration of the tank shell) and which may
employ an indirect measurement to obtain the desired quantity. Examples
of this type are weighing of cargo, sonic depth gauge (without
penetration of tank shell), pipe flow meter.
(e) All gauging devices and related fixtures which form a part of
the cargo containment barrier shall be of suitable material and shall be
designed for the pressure and temperature of the cargo in accordance
with the requirements of Subchapter F of this chapter.
(f) Use of restricted gauging devices. (1) When required in Table
151.05, cargoes carried under pressure shall have restricted gauging
devices designed so that the maximum bleed valve opening is not larger
than 0.055;inch; diameter, unless provided with an excess flow valve.
Sounding tubes are prohibited for use with cargoes having a vapor
pressure in excess of 14.7 p.s.i.a. at 115 [deg]F, if carried in an
uninsulated tank, or at 105 [deg]F, if carried in an insulated tank.
(2) When utilizing a sounding tube, the cargo tank vent system shall
be designed to prevent the discharge of cargo through the sounding tube
due to pressure build up in the cargo tank vapor space. (See Sec.
151.03-43) When cargoes carried at atmospheric pressure are required to
have a restricted gauging device, open gauges may be provided in
addition to restricted gauges for this type of cargo. However, open
gauges may not be used while cargo transfer operations are actually
being performed.
(g) Fixed tube gauges are not acceptable as primary means of
gauging. They may be used as a check on the calibration of other gauging
devices.
(h) For pressure-vessel type tanks, each automatic float, continuous
reading tape or similar type gauge not mounted directly on the tank or
dome shall be fitted with a shutoff device located as close to the tank
as practicable. When an automatic float gauging device, which gauges the
entire height of the tank, is used, a fixed tube gauge set in the range
of 85 percent to 90 percent of the water capacity of the tank shall be
provided in addition as a means of checking the accuracy of the
automatic float gauge, or other alternate means acceptable to the
Commandant may be used.
(i) Gauge glasses of the columnar type are prohibited.
(j) Flat sight glasses may be used in the design of automatic float
continuous reading tape gauges. However such glasses shall be made of
high strength material, suitable for the operating temperatures, of not
less than one-half inch in thickness and adequately protected by a metal
cover.

Sec. 151.45-5 Open hopper barges.
(a) All open hopper barges not constructed or modified in
conformance with the provisions of Subpart 151.10 of this part when
carrying in bulk any cargoes regulated by this subchapter shall meet the
provisions of this section. However, the provisions of this section are
not applicable to such barges when empty (not necessarily cleaned or
gas-freed).
(1) Except as otherwise provided in this section, no such open
hopper type barge shall be placed as lead barge in any tow. These barges
shall be placed in protected positions within the tow so that the danger
from diving or swamping will be minimized. Where, due to operating
conditions, compliance with this paragraph is impossible, the provisions
of paragraph (a)(3) of this section apply. The person in charge of the
towing vessel shall be responsible for compliance with this paragraph.
(2) No such open hopper type barge shall be moved from a loading
facility unless all void spaces and bilges are substantially free of
water. Periodic inspections and necessary pumping shall be carried out
to insure the maintenance of such water-free conditions, in order to
minimize the free surface effect in both the longitudinal and transverse
directions. Except when considered necessary for inspection or pumping,
all hatch covers and other hull closure devices for void spaces and hull
compartments shall be closed and secured at all times. In the case of
unmanned barges, the person in charge of the towing vessel shall be
deemed to be in charge of the barge, and all requirements to be carried
out on the barge shall be carried out by or under the direction of this
person.
(3) When an open hopper type barge is in an exposed position, such
that protection from swamping provided by adjoining barges cannot be
obtained from the location within the tow, it shall be the
responsibility of the person in charge of the towing vessel to control
speed so as to insure protection against diving and swamping of the
barge, having regard to its design and freeboard, and other operating
conditions.
(b) To show that special operating requirements apply to a specific
open hopper type barge, additional placards or signs shall be displayed
in at least four different locations on the barge when the cargoes
subject to this part are carried in any form in the cargo tanks. The
placards or signs shall be posted on the barge approximately amidships
on each side and near the centerline fore and aft facing outboard.
Racks, or other suitable means for mounting such placards or signs,
shall be so arranged as to provide clear visibility and shall be
protected from becoming readily damaged or obscured. The placards or
signs shall be at least
[[Page 110]]
equal in dimensions to the DOT standard tank car ``Dangerous'' placard
(10\3/4\ inches square or larger) and shall display a circle (10 inches
in diameter or larger) with alternating quadrants of white and red, and
so mounted that the red quadrants are centered on the vertical axis. The
shipper and/or owner of the barge shall be responsible for the
installation of the required placards or signs, including maintenance of
them while such barge is in temporary storage with cargo aboard. The
person in charge of the towing vessel shall be responsible for the
continued maintenance of the placards or signs while such barge is in
transit.
Sec. 151.45-6 Maximum amount of cargo.
(a) Tanks carrying liquids or liquefied gases at ambient
temperatures regulated by this subchapter shall be limited in the amount
of cargo loaded to that which will avoid the tank being liquid full at
105 [deg]F if insulated, or 115 [deg]F if uninsulated. If specific
filling densities are designated in Subpart 151.50 of this part, they
shall take precedence over that noted above.
(b) Refrigerated and semirefrigerated tanks shall be filled so that
there is an outage of at least 2 percent of the volume of the tank at
the temperature corresponding to the vapor pressure of the cargo at the
safety relief valve setting. A reduction in the required outage may be
permitted by the Commandant when warranted by special design
considerations. Normally, then, the maximum volume to which a tank may
be loaded is:
VL=0.98drV/dL
where:
VL=Maximum volume to which tank may be loaded.
V =Volume of tank.
dr=Density of cargo at the temperature required for a cargo
vapor pressure equal to the relief valve setting.
dL=Density of cargo at the loading temperature and pressure.
Sec. 151.45-7 Shipping papers.
Each barge carrying dangerous cargo shall have on board a bill of
lading, manifest, or shipping document giving the name of shipper,
location of the loading point, and the kind, grade, and approximate
quantity by compartment of each cargo in the barge. Such manifest or
bills of lading may be made out by the shipper, master of the towing
vessel, owner, or agent of the owner. However, in the case of unmanned
barges the master of the towing vessel shall either have a copy of the
shipping papers for each barge in his tow or he shall make an entry in
the towing vessel's log book giving the name of the shipper, location
where the barge was loaded, and the kind, grade, and quantity of cargo
by compartment in the barge. The barge shall not be delayed in order to
secure the exact quantities of cargo.
Sec. 151.45-8 Illness, alcohol, drugs.
A person who is under the influence of liquor or other stimulants,
or is so ill as to render him unfit to perform service shall not be
permitted to perform any duties on the barge.
Sec. 151.45-9 Signals.
While fast to a dock, a vessel during transfer of bulk cargo shall
display a red flag by day or a red light by night, which signal shall be
so placed that it will be visible on all sides. When at anchor, a vessel
during transfer of bulk cargo shall display a red flag by day, placed so
that it will be visible on all sides. This flag may be metallic.

FR 50465, Sept. 29, 1995, and 61 FR 50732, Sept. 27, 1996.
Sec. 151.50-1 General.
Special requirements found in this subpart pertain to specific
cargoes and to similar groups of cargoes. These requirements are in
addition to and take precedence over any other requirements found in
these regulations.
Sec. 151.50-5 Cargoes having toxic properties.
When table 151.05 refers to this section, the following apply:
(a) [Reserved]
(b) Independent tanks shall be designed and tested for a head of at
least 8 feet above the top of the tank using the specific gravity of the
product to
[[Page 111]]
be carried. In addition, tank design calculations shall demonstrate that
the tank can withstand, without rupture, a single loading to the highest
level to which the product may rise, if that exceeds 8 feet. In general,
plate less than five-sixteenths inch in thickness shall not be used in
the fabrication of independent tanks unless otherwise approved.
(c)(1) Cargo tanks transporting liquids having a Reid vapor pressure
exceeding 14 pounds per square inch absolute or vented at a gauge
pressure exceeding 4 pounds per square inch, or where air or water
pressure is used to discharge the cargo, shall be fabricated as arc-
welded unfired pressure vessels.
(2) Unfired pressure vessel cargo tanks shall be designed for a
pressure not less than the vapor pressure, in pounds per square inch
gauge, of the lading at 115 [deg]F, or the maximum air or water pressure
used to discharge the cargo, whichever is greater, but in no case shall
the design pressure of such tanks be less than 30 pounds per square inch
gauge.
(d) Piping. (1) The pumps and piping used for cargo transfer shall
be independent of all other piping.
(2) Where multiple cargoes are carried, and the cargo piping
conveying cargoes covered under this section are led through cargo tanks
containing other products, the piping shall be encased in a tunnel.
(3) Where cargo lines handling other products, or bilge and ballast
piping are led through tanks containing cargoes covered by this section,
the piping shall be enclosed in a tunnel.
(e) Gravity type cargo tanks shall be fitted with an approved
pressure-vacuum relief valve of not less than 2\1/2\-inch size, which
shall be set at a pressure of not less than 3 pounds per square inch
gauge, but not in excess of the design pressure of the tank.
(f) The discharge fittings from each safety relief or pressure
vacuum relief valve shall be directed in such a manner as to not impinge
on another tank, piping or any other equipment which would increase the
fire hazard should burning products be discharged from the safety or
pressure vacuum relief valve as a result of a fire or other casualty. In
addition, the discharges shall be directed away from areas where it is
likely that persons might be working and as remote as practicable from
ventilation inlets and ignition sources. A common discharge header may
be employed if desired. The area near the discharge fittings shall be
clearly marked as a hazardous area.
(g) A means shall be provided for either the reclamation or safe
venting of vapors during the loading and unloading operations. For this
purpose the safety relief or pressure vacuum relief valve shall be
provided with a valved bypass to a vapor return line shore connection
which shall be used whenever vapor return shore facilities are
available. In the event vapors must be vented to the atmosphere, a vent
riser shall extend at least 12 feet above the highest level accessible
to personnel. The vent riser may be collapsible for ease of stowage when
not in use. Vapor return lines or vent risers for tanks carrying the
same class product may be connected to a common header system if
desired. Tanks carrying cargoes covered by this section shall be vented
independent of tanks carrying other products.
(h) The pump room ventilation outlet duct exhausts shall terminate
at a distance of at least 6 feet above the enclosed space or pump room
and at least 6 feet from any entrance to the interior part of the
vessel. The discharge end of the exhaust ducts shall be located so as to
preclude the possibility of recirculating contaminated air through the
pump room, or other spaces where personnel may be present.

be ethylene oxide and propylene oxide.
(b) Alkylene oxides transported under the provisions of this part
shall be acetylene free.
(c)(1) No other product may be transported in tanks certified for an
alkylene oxide except that the Commandant may approve subsequent
transportation of other products and return to alkylene oxide service if
tanks, piping and auxiliary equipment are adequately cleaned to the
satisfaction of the Marine Inspector.
(2) Unless authorized by the Commandant, no other kind of cargo
except methane, ethane, propane, butane and pentane shall be on board a
tank vessel certificated for the carriage of an alkylene oxide at the
same time an alkylene oxide in either the liquid or vapor state is
present in any cargo tank. Alkylene oxide tanks shall not be installed
in tanks intended for any other cargo.
(d) All valves, flanges, fittings, and accessory equipment shall be
of a type suitable for use with the alkylene oxides and shall be made of
steel or stainless steel, or other materials acceptable to the
Commandant. Impurities of copper, magnesium and other acetylide-forming

the bottom of the tank or sump pit if one is provided.
(i) Venting. (1) The discharge fittings from each safety relief or
pressure vacuum relief valve shall be directed in such a manner as to
not impinge on another tank, piping or any other equipment which would
increase the fire hazard should burning products be discharged from the
safety or pressure vacuum relief valve as a result of a fire or other
casualty. In addition, the discharges shall be directed away from areas
where it is likely that persons might be working and as remote as
practicable from ventilation inlets and
[[Page 113]]
ignition sources. A common discharge header may be employed if desired.
The area near the discharge fittings shall be clearly marked as a
hazardous area.
(2) A means shall be provided for either the reclamation or safe
venting of vapors during the loading and unloading operations. For this
purpose, the safety relief or pressure vacuum relief valve shall be

this section.
(2) Ethylene oxide shall be loaded at a temperature below 70 [deg]F.
(3) When ethylene oxide is to be transported at or near atmospheric
pressure, the Commandant may permit the use of alternate methods of
storage which are consistent with the minimum requirements of this
subpart.
(b)(1) All cargo tanks shall be constructed of a carbon steel or
stainless steel acceptable to the Commandant. Impurities of copper,
magnesium and other acetylide-forming metals shall be kept to a minimum.
The chemical composition of all steel used shall be submitted to the
Commandant for approval prior to fabrication. Aluminum, copper and other
acetylide-forming metals, such as silver, mercury, magnesium, and their
alloys shall not be used as materials of construction for tanks or
equipment used in handling ethylene oxide.
(2) Cargo tanks shall meet the requirements of Class I pressure
vessels.
(3) Cargo tanks shall be designed for the maximum pressure of vapor
or gas used in discharging the cargo but in no case shall the design
pressure of such tanks be less than 75 pounds per square inch gauge. The
tank shell and heads shall not be less than \5/16\-inch thick.
(c)(1) Cargo tanks shall be located below deck in holds or enclosed
spaces with the domes or trunks extended above the weather deck and
terminating in the open. Provisions shall be made to maintain the
watertightness of the deck by means of watertight seals around such
domes or trunks. The holds or enclosed spaces, in which the ethylene
oxide tanks are located, shall not be used for any other purpose.
However, in open hopper type barges of a suitable design approved for
such service, the weatherdeck may not be required to be watertight.
(2) All cargo tanks shall be installed with the manhole openings and
all tank connections located above the weatherdeck in the open.
(3) Tanks shall be electrically bonded to the hull.
(4) No welding of any kind shall be done on cargo tanks or
supporting structure unless authorized by the Commandant.
(d) All cargo tanks, piping, valves, fittings, and similar equipment
which may contain ethylene oxide in either the liquid or vapor phase,
including the vent risers, shall be insulated. Flanges need not be
covered, but if covered, a small opening shall be left at the bottom of
the flange cover to detect leaks. Insulation shall be of an approved
incombustible material suitable for use with ethylene oxide, which does
not significantly lower the autoignition temperature and which does not
react spontaneously with ethylene oxide. The insulation shall be of such
thickness as to provide a thermal conductance of not more than 0.075
B.t.u. per square foot per degree Fahrenheit differential in temperature
per hour.
(e)(1) When cooling systems are installed to maintain the
temperature of the liquid below 90 [deg]F, at least two complete cooling
plants, automatically regulated by temperature variations within the
tanks shall be provided; each to be complete with the necessary
auxiliaries for proper operation. The control system shall also be
capable of being manually operated. An alarm shall be provided to
indicate malfunctioning of the temperature controls. The capacity of
each cooling system shall be sufficient to maintain the temperature of
the liquid cargo at or below the design temperature of the system.
(2) An alternate arrangement may consist of three cooling plants,
any two of which shall be sufficient to maintain the temperature of the
liquid cargo at
[[Page 115]]
or below the design temperature of the system.
(3) Cooling systems requiring compression of ethylene oxide are
prohibited.
(f) In addition to the shutoff valve required, all tank connections
larger than one-half inch inside pipe size, except safety relief valves
and liquid level gauging devices, shall be fitted with either internal
back pressure check valves or internal excess flow valves in conjunction
with a quick closing stop valve operable from at least two remote
locations. The quick closing stop valve shall be of the ``fail safe''
type acceptable to the Commandant and shall be equipped with a fusible
plug designed to melt between 208 [deg]F and 220 [deg]F, which will
cause the quick closing valve to close automatically in case of fire.
The quick closing valve shall be located as close to the tank as
possible.
(g) Piping systems intended for ethylene oxide service shall not be
used for any other product and shall be completely separate from all
other systems. The piping system shall be designed so that no cross
connections may be made either through accident or design.
(h) Each safety relief valve shall be set to start to discharge at
not less than 75 pounds per square inch gauge, nor more than the design
pressure of the tank.

(j)(1) The cargo shall be shipped under a suitable protective
inerting gas system, such as nitrogen. When nitrogen gas is used, the
gas inerting system shall be so designed that the vapor space above the
liquid cargo will be filled and maintained with a gas mixture of not
less than 45 percent nitrogen. Other gases proposed for inerting use may
be given consideration by the Commandant. Original charging only of
protective inerting gas at the loading facility is not considered
adequate. A sufficient amount of spare inerting gas as approved by the
Commandant shall be provided on the vessel in order to maintain the
proper concentration of the gas in the event of normal leakage or other
losses.
(2) Any inerting gas selected should be at least 98 percent pure and
free of reactive materials, such as ammonia, hydrogen sulfide, sulfur
compounds, and acetylene.
(k) Prior to loading, a sample from the cargo tank will be taken to
insure that the pad gas will meet the requirements of paragraph (j) of
this section and that the oxygen content of the vapor space will be not
more than 2 percent maximum. If necessary, a sample will be taken after
loading to insure the vapor space meets this requirement.
(l) The cargo piping shall be inspected and tested at least once in
each 2 calendar years.
(m) In those cases where the cargo transfer hose used is not part of
the barge's equipment, the person in charge of the transfer operation
shall determine that the provisions of Sec. 151.50-10(k) have been met
before using this hose. A certificate of test, supplied by the transfer
facility, will be considered as adequate for this determination.
(n) The provisions of Sec. 151.50-10 shall be complied with as a
requirement for shipping ethylene oxide.
(o) A hydrostatic test of 1\1/2\ times the design pressure shall be
made on the cargo tanks at least once in each 4 years at the time the
internal examination is made and at such other times as considered
necessary by the Officer in Charge, Marine Inspection.
