Box 12103\nNorfolk, Virginia 23541-0103\nDear Mr. Plum:\nThis is in response to your letter of February 10, 1998, requesting clarification of the periodic\nretest requirements for cylinders under the Hazardous Materials Regulations (HMR; 49 CFR\nParts 171-180). Specifically, you ask whether Halon 1301 (bromotrifluoromethane), a non-\ncorrosive fire extinguishing agent, is a fluorinated hydrocarbon gas and would qualify for the\nexception in § 173.34(e) (13).\nYes, Bromotrifluoromethane is a fluorinated hydrocarbon gas. Section 173.34(e)(13) states\nthat cylinders made in compliance with DOT-3A, DOT-AA, DOT-3A480X, DOT-4B,\nDOT-4BA, DOT-4BW, DOT-4E and used exclusively for fluorinated hydrocarbons and\nmixtures thereof which are commercially free from corroding components can be given a\ncomplete visual inspection instead of a periodic hydrostatic retest at the time periodic retest\ncomes due. Therefore, bromotrifluoromethane qualifies for the provisions in § 173.34(e) (13)\nallowing a periodic visual inspection instead of a periodic hydrostatic retest of the above\nidentified cylinders.\nI hope this answers your inquiry. If you need additional assistance, do not hesitate to contact\nus.\nSincerely,\nGilms Hillins\nDelmer F.
