Final answer:
DOT and EPA regulations must be followed when transporting cylinders containing used refrigerant, including the use of appropriate containers, labeling, and providing necessary documentation for safety and compliance.
Step-by-step explanation:
When transporting cylinders containing used refrigerant, the United States Department of Transportation (DOT) has specific regulations that must be followed. These regulations are in place to ensure the safe and secure transportation of potentially hazardous materials, which includes both the handling of certain substances and the documentation required for transport.
Apart from DOT regulations, the Environmental Protection Agency (EPA) also sets regulations regarding the handling of hazardous waste. These regulations may overlap with the DOT requirements and must be considered when transporting used refrigerants.
It's important for carriers to be fully compliant with both DOT and EPA guidelines to avoid penalties and ensure public safety. It is implied that carriers must use appropriate containers, clearly label the contents, and provide the necessary documentation to attest to the safe handling of the refrigerant.
