Which agency regulates the shipping and labeling of refrigerant cylinders?

  1. EPA

  2. DOT

  3. FDA

  4. NHTSA

The correct answer is: DOT

The regulation of the shipping and labeling of refrigerant cylinders is primarily the responsibility of the Department of Transportation (DOT). The DOT establishes standards to ensure the safe transportation of hazardous materials, which includes refrigerants. These regulations cover aspects such as the proper labeling, packaging, and handling of cylinders containing refrigerants to prevent accidents and ensure safety during transit. In contrast, the Environmental Protection Agency (EPA) primarily focuses on environmental protection regulations, including those regarding the handling of refrigerants to prevent ozone depletion and environmental harm, but it does not regulate the shipping and labeling of these materials. The Food and Drug Administration (FDA) oversees food safety and pharmaceuticals, while the National Highway Traffic Safety Administration (NHTSA) deals with vehicle and road safety, which is unrelated to refrigerants or their transportation. Thus, the DOT is the correct agency regarding the shipping and labeling protocols for refrigerant cylinders, ensuring compliance with safety regulations during transportation.
