tank for the pump to gain suction, and
if the NLS is immiscible with water or
is a solidifying cargo, all floating and
suspended NLS must be discharged.
(6) The washing machine must be operated until samples of the discharged
tank washings taken by the Surveyor
are tested using the equipment required by paragraph (a)(1)(ii) of this
section and the concentration of NLS
is below 0.1 per cent by weight.
(7) After the washing is stopped, the
remaining tank washings must be
pumped out.
(8) The Cargo Record Book must have
items 12 through 14 completed and
must show the Surveyor’s written certification of their accuracy.

Coast Guard agrees under the provisions of § 153.10 to accept the stripping
quantity, previously determined under
paragraph (b) of this section, of a tank
having similar geometry, internal
structure, and piping system.
(b) When testing a tank for stripping
quantity, the owner or operator of the
ship shall proceed as follows:
(1) Make arrangements with the Officer in Charge, Marine Inspection, for a
Coast Guard Marine Inspector to witness the stripping test.
(2) Clean and gas free the tanks to be
tested.
(3) Determine the least favorable values of list and trim for drainage within
the range allowed by the approved Procedures and Arrangements Manual.
(4) Maintain the ship’s list and trim
during the test to that determined
under paragraph (b)(3) of this section.
(5) Load the tank with enough water
so that unloading the water simulates
the final stages of unloading a full
tank of cargo.
(6) Pump out the water and strip the
tank using the procedures specified in
the approved Procedures and Arrangements Manual.
(7) After shutting the manifold valve,
open any cargo pump foot valve to
allow water trapped in the cargo pump
to drain into the tank.
(8) Open all valves in the piping system except the manifold valve and
allow the water to drain into the tank.
(9) Squeegee or sweep the water
drained under paragraphs (b)(7) and
(b)(8) of this section and any water
that stands in puddles on the tank
floor to the tank’s low point or sump
and collect in the container required
by § 153.1600(b) using the equipment required in § 153.1600(e).
(10) With the manifold valve still
closed, drain any water remaining in
the piping system on the ship’s side of
the cargo transfer manifold valve into
containers, and add this water to that
collected from the tank under paragraph (b)(9) of this section. Water collected from a cargo line serving a block
of tanks may be prorated between all
the tanks it serves if—
(i) The ship owner requests, under
the provisions of § 153.10, that the water
be prorated; and
(ii) The ship’s approved Procedures
and Arrangements Manual specifies
that no tank in the block be washed
until all the tanks in the block have
been discharged.
(c) Include any water that is trapped
in dead end pipe sections, either by—
(1) Draining the pipe sections and
adding the water to that collected in
the container under paragraphs (b)(9)
and (b)(10) of this section; or
(2) Adding an estimate of the water’s
volume to the sum calculated in paragraph (d) of this section using the
pipe’s dimensions, the ship’s list and
trim, and the geometry of the piping
system.
(d) Measure the volume of water collected in the container under paragraphs (b)(9), (b)(10), and (c)(1) of this
section and add to that volume the volume, if any, estimated under paragraph
(c)(2) of this section.

Column Heading Footnotes:
a. The cargo name must be as it appears in this column (see 153.900, 153.907). Words in italics are not part of the cargo name but may be used in addition to the cargo name. When
one entry references another entry by use of the word ‘‘see’’, and both names are in roman type, either name may be used as the cargo name (e.g., Diethyl ether, see Ethyl ether). However, the referenced entry is preferred.
The provisions contained in 46 CFR part 197, subpart C, apply to liquid cargoes containing 0.5% or more benzene by volume.
b. This column lists the IMO Annex II Pollution Category.
A, B, C, D—NLS Category of Annex II of MARPOL 73/78.
III—Appendix III of Annex II (non-NLS cargoes) of MARPOL 73/78.
#—No determination of NLS status. For shipping on an oceangoing vessel, see 46 CFR 153.900(c).
[ ]—A NLS category in brackets indicates that the product is provisionally categorized and that further data are necessary to complete the evaluation of its pollution hazards. Until the
hazard evaluation is completed, the pollution category assigned is used.
@—The NLS category has been assigned by the U.S. Coast Guard, in absence of one assigned by the IMO. The category is based upon a GESAMP Hazard Profile or by analogy to
a closely related product having an NLS assigned.
c. This column lists the hazard(s) of the commodity:
S—The commodity is included because of its safety hazards.
P—The commodity is included because of its pollution hazards.
S/P—The commodity is included because of both its safety and pollution hazards.
d. This column lists the type of containment system the cargo must have (see 153.230 through 153.232).
e. This column lists the height of any vent riser required (see 153.350 and 153.351).
f. This column lists any vent control valve required (see 153.355).
g. This column lists the type of gauging system required (see 153.400 through 153.406).

h. This column lists the type of fire protection system required. Where more than one system is listed, any listed system may be used. A dry chemical system may not be substituted for
either type of foam system unless the dry chemical system is listed as an alternative or the substitution is approved by Commandant (CG–522) (see 153.460). The types are as follows:
A is a foam system for water soluble cargoes (polar solvent foam).
B is a foam system for water insoluble cargoes (non-polar solvent foam).
C is a water spray system.
D is a dry chemical system.
NSR means there is no special requirement applying to fire protection systems.
i. This column lists sections that apply to the cargo in addition to the general requirements of this part. The 153 Part number is omitted.
j. This column lists the electrical hazard class and group used for the cargo when determining requirements for electrical equipment under Subchapter J (Electrical Engineering) of this
chapter.
A number of electrical hazard class and group assignments are based upon that which appears in ‘‘Classification of Gases, Liquids and Volatile Solids Relative to Explosion-Proof Electrical Equipment’’, Publication NMAB 353–5, National Academy Press, 1982, when not appearing in NFPA 497M, ‘‘Manual for Classification of Gases, Vapors and Dusts for Electrical Equipment in Hazardous (Classified) Locations.’’
The I-B electrical hazard does not apply to weather deck locations (see 46 CFR Part 111) for inorganic acids: Chlorosulfonic acid; Hydrochloric acid; Nitrating acid; Nitric acid (70% or
less); Oleum; Phosphoric acid; Sulfuric acid.
Abbreviations used in the Table:
NR—No requirement.
NA—Not applicable.
Abbreviations for Noxious Liquid cargoes:
N.F.—non-flammable (flash point greater than 60 deg C (140 deg F) closed cup (cc)).
F.—flammable (flash point less than or equal to 60 deg C (140 deg F) closed cup (cc)).
n.o.s.—not otherwise specified.
ST—Ship type.
Cat—Pollution category.
Footnotes for Specific Cargoes:
1. Special applicability:
153.440 and .908(a) apply to the chemical, and mixtures containing the chemical, with a viscosity of 25 mPa.s at 20 deg C (68 deg F).
153.440 and .908(b) apply to the chemical, and mixtures containing the chemical, with a melting point of 0 deg C (32 deg F) and above.
153.488 applies to the chemical, and mixtures containing the chemical, with a melting point of 15 deg C (59 deg F) and above.
2. Benzene containing cargoes.
Applies to mixtures containing no other components with safety hazards and where the pollution category is C or less.
3. Diammonium salt of Zinc ethylenediaminetetraacetic acid solution; Tetraethylenepentamine.
Aluminum is a questionable material of construction with this cargo since pitting and corrosion has been reported. The IMO Chemical Code prohibits aluminum as a material of construction for this cargo.
4. 2,4-Dichlorophenol.
Some tank pitting has been reported when this cargo is contaminated with water, including moisture in the air. The IMO Chemical Code requires that the vapor space over this cargo
be kept dry.
5. Reserved.
6. Diphenylmethane diisocyanate; Hexamethylene diisocyanate; Isophorone diisocyanate; Polymethylene polyphenyl isocyanate; Toluene diisocyanate; Trimethylhexamethylene
diisocyanate (2,2,4- and 2,4,4- isomers).
Water is effective in extinguishing open air fires but will generate hazardous quantities of gas if put on the cargo in enclosed spaces.
7. Maleic anhydride; Nitroethane; Nitroethane, 1-Nitropropane mixtures; 1- or 2-Nitropropane; Nitropropane, Nitroethane mixtures.
Dry chemical extinguishers should not be used on fires involving these cargoes since some dry chemicals may react with the cargo and cause an explosion.
8. Xylenes.
Special requirement .908(b) only applies to the para- (p-) isomer, and mixtures containing the para-isomer having a melting point of 0 deg C (32 deg F) or more.

#—No determination of NLS status. For shipping on an
oceangoing vessel, see 46 CFR 153.900(c).
[ ]—A NLS category in brackets indicates that the product is
provisionally categorized and that further data are necessary
to complete the evaluation of its pollution hazards. Until the
hazard evaluation is completed, the pollution category assigned is used.
@The NLS category has been assigned by the U.S. Coast
Guard, in absence of one assigned by the IMO. The category
is based upon a GESAMP Hazard Profile or by analogy to a
closely related product having an NLS assigned.
Abbreviations for Noxious liquid Cargoes:
N.F.—non-flammable (flash point greater than 60 degrees C (140 degrees F) cc).
n.o.s.—not otherwise specified.
ST—Ship type.
Cat—Pollution category.
