Hazardous Materials: Safety Requirements for External Product Piping on Cargo Tanks Transporting Flammable Liquids
Notice of proposed rulemaking.
PHMSA is proposing to amend the Hazardous Materials Regulations to prohibit the transportation of flammable liquids in unprotected external product piping on DOT specification cargo tank motor vehicles. If adopted as proposed, these amendments will reduce fatalities and injuries that result from accidents during transportation involving the release of flammable liquid from unprotected external product piping.
