U.S. Department of Transportation regulations (49 CFR) govern pressure vessels used to transport hazardous materials, including poisonous gases and liquids. DOT specification containers and UN portable tanks must meet detailed design, fabrication, testing, and marking requirements specific to the hazardous materials they will contain. These regulations interface with ASME codes while adding transportation-specific requirements for impact resistance, cargo protection, and emergency response compatibility.
Transportation of hazardous materials exposes the public to risks that stationary storage does not—highway accidents, rail derailments, and handling incidents can release toxic contents in populated areas. DOT regulations address these unique risks through requirements for container integrity during transportation events, proper marking and placarding, emergency shutoff systems, and compatibility with emergency response procedures. Roben Manufacturing’s DOT-certified vessels meet these specialized requirements while maintaining ASME code compliance for stationary service compatibility.
