Title 49 - Transportation
Effective Date(s): September 11, 2006 11. In §171.12a, paragraph (b)(13) is revised to read as follows: * * * * * (b) * * * (13) When the provisions of this subchapter require that a DOT specification or a UN standard packaging must be used for a hazardous material, a packaging authorized by the TDG Regulations may be used only if it corresponds to the DOT specification or UN standard authorized by this subchapter. Unless otherwise excepted in this subchapter, a cylinder (including UN pressure receptacles) may not be transported unless; (i) The packaging is a UN pressure receptacle marked with the letters “CAN” for Canada as a country of manufacture or a country of approval or is a cylinder that was manufactured, inspected and tested in accordance with a DOT specification or a UN standard prescribed in part 178 of this subchapter, except that cylinders not conforming to these requirements must meet the requirements in §173.301(j), (k), (l) or (m) of this subchapter. (ii) The cylinder conforms to the applicable requirements in part 173 of this subchapter for the hazardous material involved; and (iii) For an aluminum cylinder in oxygen service used for other than aircraft parts, the cylinder openings conform to the requirements of this paragraph. For a DOT specification cylinder (e.g. DOT 3AL), the opening must be configured with straight (parallel) threads. UN pressure receptacles may have straight (parallel) or tapered threads provided the cylinder is marked with the thread type, e.g. “17E, 25E, 18P, 25P” and fitted with the properly marked valve. * * * * *
