Hazardous Materials: Requirements for the Storage of Explosives and Other High-Hazard Materials During Transportation

Summary: PHMSA is considering requirements to address the current safety and security risks associated with the storage of explosives during transportation. In this notice, we are soliciting comments concerning measures to reduce the risks posed by the storage of explosives while they are in transportation and whether regulatory action is warranted. We also invite comments as to whether enhanced requirements for storage incidental to movement should apply to other hazardous materials (e.g., materials toxic by inhalation).
