(7) "T" codes. (i) These provisions apply to the transportation of
hazardous materials in UN and IM Specification 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 §180.605 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 §178.275(g)(3) of this subchapter for the pressure relief
devices. When the word "Normal" is indicated, §178.275(g)(3) of this subchapter
does not apply. Column 5 references the applicable requirements for bottom
openings in part 178 of this subchapter or references "Prohibited" which means
bottom openings are prohibited. The table follows: (iii) The following table specifies the portable tank requirements applicable
to T23 for self-reactive substances of Division 4.1 and organic peroxides of
Division 5.2 which are authorized to be transported in portable tanks: (iv) The following portable tank instruction applies to portable tanks used
for the transportation of liquefied compressed gases. The T50 table provides the
UN identification number and proper shipping name for each liquefied compressed
gas authorized to be transported in a T50 portable tank. The table provides
maximum allowable working pressures, bottom opening requirements, pressure
relief device requirements and degree of filling requirements for each liquefied
compressed gases permitted for transportation in a T50 portable tank. In the
minimum test pressure column, "small" means a portable tank with a diameter of
1.5 meters or less when measured at the widest part of the shell, "sunshield"
means a portable tank with a shield covering at least the upper third of the
shell, "bare" means no sunshield or insulation is provided, and "insulated"
means a complete cladding of sufficient thickness of insulating material
necessary to provide a minimum conductance of not more than 0.67
w/m2/k. In the pressure relief requirements column, the word "Normal"
denotes that a frangible disc as specified in §178.276(e)(3) of this subchapter
is not required. The T50 table follows: (v) When portable tank instruction T75 is referenced in Column (7) of the
§172.101 Table, the applicable refrigerated liquefied gases are authorized to be
transported in portable tanks in accordance with the requirements of §178.277 of
this subchapter.
(vi) UN and IM portable tank codes/special provisions. When a specific
portable tank instruction is specified by a T Code in Column (7) of the §172.101
Table for a specific hazardous material, a Specification portable tank
conforming to an alternative tank instruction may be used if:
(A) the alternative portable tank has a higher or equivalent test pressure
(for example, 4 bar when 2.65 bar is specified);
(B) the alternative portable tank has greater or equivalent wall thickness
(for example, 10 mm when 6 mm is specified);
(C) the alternative portable tank has a pressure relief device as specified
in the T Code. If a frangible disc is required in series with the reclosing
pressure relief device for the specified portable tank, the alternative portable
tank must be fitted with a frangible disc in series with the reclosing pressure
relief device; and
(D) With regard to bottom openings --
(1) When two effective means are specified, the alternative portable
tank is fitted with bottom openings having two or three effective means of
closure or no bottom openings; or
(2) When three effective means are specified, the portable tank has no
bottom openings or three effective means of closure; or
(3) When no bottom openings are authorized, the alternative portable
tank must ot have bottom openings.
(vii) When a hazardous material is not assigned a portable tank T Code or TP
9 is referenced in Column (7) of the §172.101 Table, the hazardous material may
only be transported in a portable tank if approved by the Associate
Administrator.
(viii) Portable tank special provisions are assigned to certain hazardous
materials to specify requirements that are in addition to those provided by the
portable tank instructions or the requirements in part 178 of this subchapter.
