    13. In Appendix B to Sec. 172.101, paragraphs 1. and 2. would be 
revised and the List of Marine Pollutants would be amended by removing 
73 entries, adding 2 entries and revising 2 entries in appropriate 
alphabetical order to read as follows:

Appendix B to Sec. 172.101--List of Marine Pollutants

    1. See Sec. 171.4 of this subchapter for applicability of marine 
pollutants. This appendix lists potential marine pollutants as 
defined in Sec. 171.8 of this subchapter.
    2. Marine pollutants listed in this appendix are not necessarily 
listed by name in the Sec. 172.101 Table. If a marine pollutant not 
listed by name or by synonym in the Sec. 172.101 Table meets the 
definition of any hazard Class 1 through 8, then you must determine 
the class and division of the material in accordance with 
Sec. 173.2a of this subchapter. You must also select the most 
appropriate hazardous material description and proper shipping name. 
If a marine pollutant not listed by name or by synonym in the 
Sec. 172.101 Table does not meet the definition of any Class 1 
through 8, then you must offer it for transportation under the most 
appropriate of the following two Class 9 entries: ``Environmentally 
hazardous substances, liquid, n.o.s.,'' UN3082, or ``Environmentally 
hazardous substances, solid, n.o.s.,'' UN3077.

    14. In Sec. 172.102, in paragraph (c)(1), Special Provisions 43, 
110, 128 and 136 would be revised and Special Provisions 139, 142 and 
143 would be added; paragraph (c)(3) introductory text, Special 
Provisions B53 and B69 and paragraphs (c)(4) and (c)(7) would be 
revised; and in paragraph (c)(8), Specials Provisions W7, W8 and W9 
would be added in numerical order to read as follows:


Sec. 172.102  Special provisions.

* * * * *
    (c) * * *
    (1) * * *

Code/Special Provisions

* * * * *
    43  The membrane filters, including paper separators and coating 
or backing materials, that are present in transport, must not be 
able to propagate a detonation as tested by one of the tests 
described in the UN Manual of Tests and Criteria, Part I, Test 
series 1(a). On the basis of the results of suitable burning rate 
tests, and taking into account the standard tests in the UN Manual 
of Tests and Criteria, Part III, subsection 33.2.1, nitrocellulose 
membrane filters in the form in which they are to be transported 
that do not meet the criteria for a Division 4.1 material are not 
subject to the requirements of this subchapter. Packagings must be 
so constructed that explosion is not possible by reason of increased 
internal pressure. Nitrocellulose membrane filters covered by this 
entry, each with a mass not exceeding 0.5 g, are not subject to the 
requirements of this subchapter when contained individually in an 
article or a sealed packet.
* * * * *
    110  Fire extinguishers transported under UN1044 may include 
installed actuating cartridges (cartridges, power device of Division 
1.4C or 1.4S), without changing the classification of Division 2.2, 
provided the aggregate quantity of deflagrating (propellant) 
explosives does not exceed 3.2 grams per extinguishing unit.
* * * * *
    128  Regardless of the provisions of Sec. 172.101(c)(12), 
aluminum smelting by-products, aluminum remelting by-products and 
coated magnesium granules described under these entries meeting the 
definition of Class 8, Packing Group II or III, may be classed as a 
Division 4.3 material and transported under this entry. The presence 
of a Class 8 hazard must be communicated as required by this part 
for subsidiary hazards.
* * * * *
    136  This entry only applies to machinery and apparatus 
containing hazardous materials as in integral element of the 
machinery or apparatus. It may not be used to describe machinery or 
apparatus for which a proper shipping name exists in the 
Sec. 172.101 Table. Except when approved by the Associate 
Administrator, machinery or apparatus may only contain hazardous 
materials for which exceptions are referenced in Column (8) of the 
Sec. 172.101 Table and are provided in part 173, subpart D, of this 
subchapter. Hazardous materials shipped under this entry are 
excepted from the labeling requirements of this subchapter unless 
offered for transportation or transported by aircraft and are not 
subject to the placarding requirements of subpart F of part 173 of 
this subchapter. Orientation markings as described in Sec. 172.312 
(a)(2) are required when liquid hazardous materials may escape due 
to incorrect orientation. The machinery or apparatus, if unpackaged, 
or the packaging in which it is contained shall be marked 
``Dangerous goods in machinery'' or ``Dangerous goods in 
apparatus'', as appropriate, with the identification number UN3363. 
For transportation by aircraft, machinery or apparatus may not 
contain any material forbidden for transportation by passenger or 
cargo aircraft. The Associate Administrator may except from the 
requirements of this subchapter, equipment, machinery and apparatus 
provided:
    a. It is shown that it does not pose a significant risk in 
transportation;
    b. The quantities of hazardous materials do not exceed those 
specified in Sec. 173.4 of this subchapter; and
    c. The equipment, machinery or apparatus conforms with 
Sec. 173.222 of this subchapter.
* * * * *
    139  Use of the ``special arrangement'' proper shipping names 
for international shipments must be made under an IAEA Certificate 
of Competent Authority issued by the U.S. Competent Authority in 
accordance with the requirements in Sec. 173.471, Sec. 173.472, or 
Sec. 173.473 of this subchapter. Use of these proper shipping names 
for domestic shipments may be made only under a DOT exemption, as 
defined in, and in accordance with the requirements of subpart B of 
part 107 of this subchapter.
* * * * *
    142  These hazardous materials may not be classified and 
transported unless authorized by the Associate Administrator. The 
Associate Administrator will base the authorization on results from 
Series 2 tests and a Series 6(c) test from the UN Manual of Tests 
and Criteria on packages as prepared for transport in accordance 
with the requirements of this subchapter.
    143  These articles may contain:
    a. Division 2.2 compressed gases, including oxygen;
    b. Signal devices (Class 1) which may include smoke and 
illumination signal flares. Signal devices must be packed in plastic 
or fiberboard inner packagings;
    c. Electric storage batteries;
    d. First aid kits; or
    e. Strike anywhere matches.
* * * * *

    (3) ``B'' codes. These provisions apply only to bulk packagings, 
other than IBCs:

                                water-resistant or shall be fitted with
                                a sift-proof and water-resistant liner.
BB4..........................  Flexible, fiberboard or wooden IBCs must
                                be sift-proof and water-resistant or be
                                fitted with a sift-proof and water-
                                resistant liner.
BB5..........................  IBCs must be provided with a device to
                                allow venting. The inlet to the venting
                                device must be located in the vapor
                                space of the IBC under maximum filling
                                conditions.
BB6..........................  Non-specification bulk bins are
                                authorized.

    (7) ``T'' codes. (i) These provisions apply to the transportation 
of UN portable tanks. Portable tank instructions specify the 
requirements applicable to a portable tank when used for the 
transportation of a specific hazardous material. These requirements 
must be met in addition to the design and construction specifications 
in part 178 of this subchapter. Portable tank instructions T1 through 
T22 specify the applicable minimum test pressure, the minimum shell 
thickness (in reference steel), bottom opening requirements and 
pressure relief requirements. In T23, the organic peroxides and self-
reactive substances which are authorized to be transported in portable 
tanks are listed along with the applicable control and emergency 
temperatures. Liquefied compressed gases are assigned to portable tank 
instruction T50. T50 provides the maximum allowable working pressures, 
bottom opening requirements, pressure relief requirements and degree of 
filling requirements for liquefied compressed gases permitted for 
transport in portable tanks. Refrigerated liquefied gases which are 
authorized to be transported in portable tanks are specified in tank 
instruction T75.
    (ii) The following table specifies the portable tank requirements 
applicable to T Codes T1 through T22. Column 1 specifies the T Code. 
Column 2 specifies the minimum test pressure, in bar (1 bar = 14.5 
psig), at which the periodic hydrostatic testing required by 
Sec. 173.32b of this subchapter must be conducted. Column 3 specifies 
the section reference for minimum shell thickness or, alternatively, 
the minimum shell thickness value. Column 4 specifies the applicability 
of Sec. 178.275(f)(3) of this subchapter for the pressure relief 
devices. When the word ``Normal'' is indicated, Sec. 178.275(f)(3) of 
this subchapter does not apply. Column 5 either references the 
applicable requirements for bottom openings in part 178 of this 
subchapter, or references ``Prohibited'' which means bottom openings

part 178 of this subchapter. Portable tank special provisions are 
designated with the abbreviation TP (tank provision) and are assigned 
to specific hazardous materials in Column (7) of the Sec. 172.101 
Table. The following is a list of the portable tank special provisions:

Code/Special Provisions

TP1  The maximum degree of filling must not exceed the degree of 
filling determined by the following (see Note 1 following TP3 for an 
explanation of the coefficients):
[GRAPHIC] [TIFF OMITTED] TP23OC00.000

TP2  The maximum degree of filling must not exceed the degree of 
filling determined by the following (see Note 1 following TP3):
[GRAPHIC] [TIFF OMITTED] TP23OC00.001

TP3  a. For liquids transported under elevated temperature, the 
maximum degree of filling is determined by the following:
[GRAPHIC] [TIFF OMITTED] TP23OC00.002

    Where:  is the mean coefficient of cubical expansion of 
the liquid between the mean temperature of the liquid during filling 
(tf) and the maximum mean bulk temperature during 
transportation (tr) both in degrees celsius.
    b. For liquids transported under ambient conditions  
may be calculated using the formula:
[GRAPHIC] [TIFF OMITTED] TP23OC00.003

    Where: d15 and d50 are the densities of 
the liquid at 15  deg.C (59  deg.F) and 50  deg.C (122  deg.F), 
respectively.

TP4  The maximum degree of filling for portable tanks must not 
exceed 90%.

TP5  [Reserved.]

TP6  To prevent the tank from bursting in an event, including fire 
engulfment under the conditions prescribed in CGA pamphlet S-1.2 
(see Sec. 171.7 of this subchapter), it must be equipped with 
pressure relief devices that are adequate in relation to the 
capacity of the tank and the nature of the hazardous material 
transported.

TP7  The vapor space must be purged of air by nitrogen or other 
means.

TP8  A portable tank having a minimum test pressure of 1.5 bar (150 
kPa) may be used when the flashpoint of the hazardous material 
transported is greater than 0  deg.C (32  deg.F).

TP9  A hazardous material assigned to special provision TP9 in 
Column (7) of the Sec. 172.101 Table may only be transported in a 
portable tank if approved by the Associate Administrator.

TP10  The portable tank must be fitted with a lead lining at least 5 
mm (0.2 inches) thick. The lead lining must be tested annually to 
ensure that it is intact and functional. Another suitable lining 
material may be used if approved by the Associate Administrator.

TP12  This material is considered highly corrosive to steel.

TP13  Self-contained breathing apparatus must be provided when this 
hazardous material is transported by sea.

TP16  The tank must be protected against over and under 
pressurization which may be experienced during transportation. The 
means of protection must be approved by the approval agency 
designated to approve the portable tank in accordance with the 
procedures in subpart E, part 107 of this subchapter. The pressure 
relief device must be preceded by a frangible disk in accordance 
with the requirements of Sec. 178.275(f)(3) of this subchapter to 
prevent crystallization of the product in the pressure relief 
device.

TP17  Only inorganic non-combustible materials may be used for 
thermal insulation of the tank.

TP18  The temperature of this material must be maintained between 18 
 deg.C (64.4  deg.F) and 40  deg.C (104  deg.F) while in 
transportation. Portable tanks containing solidified methacrylic 
acid must not be reheated during transportation.

TP19  The calculated wall thickness must be increased by 3 mm at the 
time of construction. Wall thickness must be verified ultrasonically 
at intervals midway between periodic hydraulic tests (every 2.5 
years). The portable tank must not be used if the wall thickness is 
less than that prescribed by the applicable T code in Column (7) of 
the Table for this material.

TP20  This hazardous material must only be transported in insulated 
tanks under a nitrogen blanket.

TP21  The wall thickness must not be less than 8 mm. Tanks must be 
hydraulically tested and internally inspected at intervals not 
exceeding 2.5 years.

TP22  Lubricants for portable tank fittings must be oxygen 
compatible.

TP24  The portable tank may be fitted with a device to prevent the 
build up of excess pressure due to the slow decomposition of the 
hazardous material being transported. The device must be in the 
vapor space when the tank is filled under maximum filling 
conditions. This device must also prevent an unacceptable amount of 
leakage of liquid in the case of overturning.

TP25  Sulphur trioxide 99.95% pure and above may be transported in 
tanks without an inhibitor provided that it is maintained at a 
temperature equal to or above 32.5  deg.C (90.5  deg.F).

TP26  The heating device must be exterior to the shell. For UN 3176, 
this requirement only applies when the hazardous material reacts 
dangerously with water.

TP27  A portable tank having a minimum test pressure of 4 bar (400 
kPa) may be used provided the calculated test pressure is 4 bar or 
less based on the MAWP of the hazardous material, as defined in 
Sec. 178.275, where the test pressure is 1.5 times the MAWP.

TP28  A portable tank having a minimum test pressure of 2.65 bar 
(265 kPa) may be used provided the calculated test pressure is 2.65 
bar or less based on the MAWP of the hazardous material, as defined 
in Sec. 178.275 of this subchapter, where the test pressure is 1.5 
times the MAWP.

TP29  A portable tank having a minimum test pressure of 1.5 bar 
(150.0 kPa) may be used provided the calculated test pressure is 1.5

    25. Section 173.32 would be revised to read as follows:


Sec. 173.32  Requirements for the use of portable tanks.

    (a) General requirements. No person may offer a hazardous material 
for transportation in a portable tank except as authorized by this 
subchapter.
    (1) Except as otherwise provided in this subpart, a portable tank 
may not be used for the transportation of a hazardous material unless 
it meets the requirements of this subchapter.
    (2) No person may fill and offer for transportation a portable tank 
when the prescribed periodic test or inspection under subpart G of part 
180 of this subchapter has become due until the test or inspection has 
been successfully completed. This requirement does not apply to any 
portable tank filled prior to the test or inspection due date.
    (3) When a portable tank is used as a cargo tank container, it 
shall conform to all the requirements prescribed for cargo tank 
containers. (See Sec. 173.33.)
    (b) Substitute packagings. A particular Specification portable tank 
may be substituted for another portable tank as follows:
    (1) An IM or UN portable tank may be used whenever an IM or UN 
portable tank having less stringent requirements is authorized provided 
the portable tank meets or exceeds the requirements for pressure-relief 
devices, bottom outlets and any other special provisions specified in 
Sec. 172.102(c)(7)(vi) of this subchapter.
    (2) Where a Specification IM101 or IM102 portable tank is 
prescribed, a Specification 51 portable tank otherwise conforming to 
the special commodity requirements of Sec. 172.102(c)(7) of this 
subchapter may be used.
    (3) A DOT Specification 51 portable tank may be used whenever a DOT 
Specification 56, 57, or 60 portable tank is authorized. A DOT 
Specification 60 portable tank may be used whenever a DOT Specification 
56 or 57 portable tank is authorized. A higher integrity tank used 
instead of a specified portable tank must meet the same design profile; 
for example, a DOT Specification 51 portable tank must be lined if used 
instead of a lined DOT Specification 60 portable tank.
    (c) Grandfather provisions for portable tanks--(1) Continued use of 
specification 56 and 57 portable tanks. Continued use of an existing 
portable tank constructed to DOT Specification 56 or 57 is authorized 
only for a tank constructed before October 1, 1996. A stainless steel 
portable tank internally lined with polyethylene that was constructed 
on or before October 1, 1996, and that meets all requirements of DOT 
Specification 57 except for being equipped with a polypropylene 
discharge ball valve and polypropylene secondary discharge opening 
closure, may be marked as a Specification 57 portable tank and used in 
accordance with the provisions of this section.
    (2) A DOT Specification 51 and IM 101 or IM 102 portable tank may 
not be manufactured after January 1, 2003 may continue to be used for 
the transportation of a hazardous material provided they fulfill the 
requirements of

[[Page 63411]]

this subchapter, including the specification requirements and the 
requirements of this subchapter for the transportation of the 
particular hazardous material (see Sec. 171.14(d)(5) of this 
subchapter), and provided it conforms to the periodic inspection and 
tests specified for the particular portable tank in subpart G of part 
180 of this subchapter. On and after January 1, 2003, all newly 
manufactured portable tanks must conform to the requirements for the 
design, construction and approval of UN portable tanks as specified in 
Secs. 178.273, 178.274, 178.275, 178.276 and 178.277 of this 
subchapter.
    (3) A DOT Specification portable tank manufactured prior to January 
1, 1992 that is equipped with a non-reclosable pressure relief device 
may continue in service for the hazardous materials for which it is 
authorized. Except for a DOT Specification 56 or 57 portable tank, a 
DOT Specification portable tank manufactured after January 1, 1992, 
used for materials meeting the definition for Division 6.1 liquids, 
Packing Group I or II, Class 2 gases, or Class 3 or 4 liquids, must be 
equipped with a re-closing pressure relief valve having adequately 
sized venting capacity.
    (d) Maximum Allowable Working Pressure. (1) Prior to filling and 
offering a portable tank for transportation, the shipper must confirm 
that the portable tank conforms to the specification required for the 
hazardous material and that the maximum allowable working pressure 
(MAWP) of the portable tank is greater than or equal to the highest 
pressure obtained under the following conditions:
    (i) For compressed gases and certain refrigerated liquids that are 
not cryogenic liquids and that are not transported in a UN portable 
tank, the pressure prescribed in Sec. 173.315. For liquefied compressed 
gases transported in a UN portable tank, the pressures prescribed in 
T50 in Sec. 172.102 of this subchapter.
    (ii) For liquid hazardous materials the pressures specified in 
Sec. 178.275(a) of this subchapter used for determining the MAWP.
    (iii) The maximum pressure used to load or unload the hazardous 
material.
    (2) Unless otherwise specified, where a portable tank is 
authorized, the minimum tank design pressure is 172 kPa (25 psig) for 
any Packing Group I or Packing Group II liquid hazardous material that 
meets more than one hazard class definition.
    (e) External inspection prior to filling. Each portable tank must 
be given a complete external inspection. Any unsafe condition must be 
corrected prior to its being offered for transportation. The external 
inspection shall include a visual inspection of:
    (1) The shell, piping, valves and other appurtenances for corroded 
areas, dents, defects in welds and other defects such as missing, 
damaged, or leaking gaskets;
    (2) All flanged connections or blank flanges for missing or loose 
nuts and bolts;
    (3) All emergency devices for corrosion, distortion, or any damage 
or defect that could prevent their normal operation;
    (4) All required markings on the tank for legibility; and
    (5) Any device for tightening manhole covers to ensure such devices 
are operative and adequate to prevent leakage at the manhole cover.
    (f) Loading requirements. (1) A hazardous material may not be 
loaded in a portable tank if the part of the tank or any of its 
appurtenances having contact with the material during transportation 
would be damaged, would cause a dangerous reaction with the material or 
would compromise the ability of the portable tank to retain the 
hazardous material.
    (2) A hazardous material may not be loaded in a portable tank 
unless it has pressure relief devices providing total relieving 
capacity meeting the requirements of this subchapter.
    (3) Except during a hydrostatic test, a portable tank may not be 
subjected to a pressure greater than its maximum allowable working 
pressure.
    (4) A portable tank may not be loaded to a gross weight greater 
than the maximum allowable gross weight specified on its identification 
plate.
    (5) Except for a non-flowable solid or a liquid with a viscosity of 
2,680 centistokes (millimeters squared per second) or greater at 
20 deg.C (68  deg.F), a portable tank or compartment thereof having a 
volume greater than 7,500 L (1,980 gallons) may not be loaded to a 
filling density of more than 20% and less than 80% by volume. This 
filling restriction does not apply if a portable tank is divided by 
partitions or surge plates into compartments of not more than 7,500 L 
(1,980) capacity. Portable tanks must not be offered for transportation 
in an ullage condition liable to produce an unacceptable hydraulic 
force due to surge.
    (6) The outage for a portable tank may not be less than 2% at a 
temperature of 50  deg.C (122  deg.F). For UN portable tanks, the 
applicable maximum filling limits apply as specified according to the 
assigned TP codes in Column (7) of the Sec. 172.101 Table of this 
subchapter except when transported domestically.
    (7) Each tell-tale indicator for the space between a frangible disc 
and a safety relief valve mounted in series must be checked after the 
tank is filled and prior to transportation to ensure that the frangible 
disc is leak free. Any leakage through the frangible disc must be 
corrected prior to offering the tank for transportation. The tell-tale 
device must be designed to prevent the loss of any hazardous material 
through the device itself while the tank is in transportation.
    (8) During filling, the temperature of the hazardous materials 
shall not exceed the limits of the design temperature range of the 
portable tank.
    (9) The maximum mass of liquefied compressed gas per liter (gallon) 
of shell capacity (kg/L or lbs./gal.) may not exceed the density of the 
liquefied compressed gas at 50  deg.C (122  deg.F). The portable tank 
must not be liquid full at 60  deg.C (140  deg.F).
    (g) Relief system. Any DOT Specification portable tank manufactured 
prior to January 1, 1992 that is equipped with a non-reclosable 
pressure relief device may continue in service for the hazardous 
materials for which it it is authorized. Except for DOT Specification 
56 and 57 portable tanks, any DOT Specification portable tank 
manufactured after January 1, 1992 used for materials meeting the 
definition for Division 6.1 liquids Packing Group I or II, Class 2 
gases, or Class 3 or 4 liquids must be equipped with a reclosing 
pressure relief valve having adequately sized venting capacity.
    (h) Additional requirements for specific modal transport. In 
addition to other applicable requirements, the following apply:
    (1) A portable tank containing a hazardous material may not be 
loaded on a highway or rail transport vehicle unless loaded entirely 
within the horizontal outline thereof, without overhang or projection 
of any part of the tank assembly. In addition, for unloading a portable 
tank, see Sec. 177.834(h) of this subchapter.
    (2) A portable tank used for the transportation of flammable 
liquids by rail may not be fitted with non-reclosing pressure relief 
devices except in series with reclosing pressure relief valves.
    (3) A portable tank or Specification 106A or 110A multi-unit tank 
car containing a hazardous material may not be offered for 
transportation aboard a passenger vessel unless:
    (i) The vessel is operating under a change to its character of 
vessel certification as defined in Sec. 171.8 of this subchapter; and

[[Page 63412]]

    (ii) The material is permitted to be transported aboard a passenger 
vessel in the Sec. 172.101 Table of this subchapter.
    (i) Additional general commodity specific requirements. In addition 
to other applicable requirements, the following requirements apply:
    (1) Each uninsulated portable tank used for the transportation of 
liquefied compressed gases must have an exterior surface finish that is 
significantly reflective, such as a light-reflecting color if painted, 
or a bright reflective metal or other material if unpainted.
    (2) If a hazardous material is being transported in a molten state, 
the portable tank must be thermally insulated with suitable insulation 
material of sufficient thickness that the overall thermal conductance 
is not more than 0.080 Btu per hour per square foot per degree 
Fahrenheit differential.
    (j) Additional requirements for portable tanks other than IM 
specification and UN portable tanks. (1) The bursting strength of any 
piping and fittings must be at least four times the design pressure of 
the tank, and at least four times the pressure to which, in any 
instance, it may be subjected in service by the action of a pump or 
other device (not including safety relief valves) that may subject 
piping to pressures greater than the design pressure of the tank.
    (2) Pipe joints must be threaded, welded or flanged. If threaded 
pipe is used, the pipe and pipe fittings must not be lighter than 
(Schedule 80) weight. Non-malleable metals must not be used in the 
construction of valves or fittings. Where copper tubing is permitted, 
joints must be brazed or be of equally strong metal union type. The 
melting point of brazing material may not be lower than 1,000  deg.F 
(537.8 deg.C). The method of joining tubing must not decrease the 
strength of the tubing such as by the cutting of threads.
    (3) Non-malleable metals may not be used in the construction of 
valves or fittings.
    (4) Suitable provision must be made in every case to allow for 
expansion, contraction, jarring and vibration of all pipe. Slip joints 
may not be used for this purpose.
    (5) Piping and fittings must be grouped in the smallest practicable 
space and must be protected from damage as required by the 
specification.
    (6) All piping, valves and fittings on every portable tank must be 
leakage tested with gas or air after installation and proved tight at 
not less than the design pressure of the portable tank on which they 
are used. In the event of replacement, all such piping, valves, or 
fittings so replaced must be tested in accordance with the requirements 
of this section before the portable tank is returned to transportation 
service. The requirements of this section apply to all hoses used on 
portable tanks, except that hoses may be tested either before or after 
installation on the portable tank.
    (7) All materials used in the construction of portable tanks and 
their appurtenances may not be subject to destructive attack by the 
contents of the tank.
    (8) All parts of the portable tanks and appurtenances for anhydrous 
ammonia must be steel. No aluminum, copper, silver, zinc, nor their 
alloys may be used. Brazed joints may not be used.
    (9) Each outlet of a portable tank used for the transportation of 
liquefied compressed gases, except carbon dioxide, must be provided 
with a suitable automatic excess-flow valve (see definition in 
Sec. 178.337-1(g) of this subchapter). These valves must be located 
inside the portable tank or at a point outside the portable tank where 
the line enters or leaves the portable tank. The valve seat must be 
located inside the portable tank or may be located within a welded 
flange or its companion flange, or within a nozzle or within a 
coupling. The installation must be made in such a manner as to 
reasonably assure that any undue strain which causes failure requiring 
functioning of the valve shall cause failure in such a manner that it 
will not impair the operation of the valve.
    (i) Safety device connections and liquid level gauging devices that 
are constructed so that the outward flow of tank contents willl not 
exceed that passed by an opening of 0.1397 cm (0.0550 inches) are not 
required to be equipped with excess-flow valves.
    (ii) An excess-flow valve must close automatically if the flow 
reaches the rated flow of gas or liquid specified by the original valve 
manufacturer when piping mounted directly on the valve is sheared off 
before the first valve, pump, or fitting downstream from the excess 
flow valve.
    (iii) An excess-flow valve may be designed with a by-pass, not to 
exceed a 0.1016 cm (0.040 inches) diameter opening to allow 
equalization of pressure.
    (iv) Filling and discharge lines must be provided with manually 
operated shut-off valves located as close to the tank as practical. The 
use of ``Stop-Check'' valves to satisfy with one valve the requirements 
of this section is forbidden.
    (10) Each portable tank used for carbon dioxide and nitrous oxide 
must be lagged with a suitable insulation material of such thickness 
that the overall thermal conductance is not more than 0.08 Btu per 
square foot per degree Fahrenheit differential in temperature per hour. 
The conductance must be determined at 60 deg. Fahrenheit. Insulation 
material used on portable tanks for nitrous oxide must be 
noncombustible.
    (11) A refrigerating and/or heating coil or coils must be installed 
in portable tanks used for carbon dioxide and nitrous oxide. Such coils 
must be tested externally to at least the same pressure as the test 
pressure of the portable tank. The coils must also be tested internally 
to at least twice the working pressure of the heating or refrigerating 
system to be used, but in no case less than the test pressure of the 
portable tank. Such coils must be securely anchored. The refrigerant or 
heating medium to be circulated through the coil or coils must be such 
as to cause no adverse chemical reaction with the portable tank or its 
contents in the event of leakage.
