Updated as of May 29, 2018 PHMSA is amending the Hazardous Materials Regulations to revise certain requirements applicable to the manufacture, maintenance, and use of DOT and MC specification cargo tank motor vehicles, DOT specification cylinders and UN pressure receptacles. The revisions are based on petitions for rulemaking submitted by the regulated community and are intended to enhance the safe transportation of hazardous materials in commerce, clarify regulatory requirements, and reduce operating burdens on cargo tank and cylinder manufacturers, requalifiers, carriers, shippers, and users. The most significant amendment adopted in this final rule addresses a safety issue identified by the National Transportation Safety Board concerning the transportation of compressed gases in cylinders mounted on motor vehicles or in frames, commonly referred to as tube trailers.
