Dear Mr. Cay: as:

This responds to your request for clarification of the periodic inspection and test requirements for non-DOT specification cargo tanks authorized under the Hazardous Materials Regulations HMR; 49 CFR Parts 171-180). Specifically, you ask about inspection and retest requirements for non-DOT specification cargo tanks authorized to transport elevated temperature materials.

A non-DOT specification cargo tank used for the transportation of elevated temperature materials, such as molten sulfur, must meet the general requirements in § 173.247(g) of the HMR. A non- DOT specification cargo tank is not subject to the periodic inspection or retest requirements of the HMR. It is the shipper"s responsibility to assure that the cargo tank conforms to all applicable HMR requirements. Note that in accordance with § 173.24(e), the shipper must ensure that a packaging is compatible with its lading even if that packaging is authorized for transportation of the material in Part 173 of the HMR. In the particular case of molten sulfur, the variability of its composition and other factors related to the operational service of the cargo tank may require that a shipper institute certain inspections and frequencies beyond that required of a comparable DOT specification tank.

I hope this information is helpful. Please contact us if you require additional assistance

Sincerely,

 

John A. Gale
