Hazardous Materials: Use of DOT Specification 39 Cylinders for Liquefied Flammable Compressed Gas

Safety advisory notice, revised.
PHMSA is issuing this revised safety advisory notice to address concerns of offerors and users of DOT Specification 39 (DOT-39) cylinders that exceed 75 cubic inches (in\3\) (1.23 L) and to provide clarification of the initial safety advisory notice we issued on this subject on December 13, 2016 (Notice No. 2016-14). DOT-39 cylinders exceeding 75 in\3\ (1.23 L) should not contain liquefied flammable compressed cyclopropane, ethane, or ethylene, or liquefied petroleum gases. PHMSA advises against the filling or transporting of these gases in DOT-39 cylinders when the cylinder's internal volume exceeds 75 in\3\ (1.23 L).
