Portable refillable tanks or containers used to ship CFC or HCFC refrigerants must meet what standards?

Portable refillable tanks or containers that are used to ship CFC (chlorofluorocarbon) or HCFC (hydrochlorofluorocarbon) refrigerants are required to adhere to standards set forth by the Department of Transportation (DOT). This is crucial because these substances are classified as hazardous materials due to their potential environmental and health impacts. The DOT regulations cover the safe and proper packaging, labeling, and transport of hazardous materials, including refrigerants, ensuring they are handled in a way that minimizes risk to public safety and the environment during transit.

While the Community Right to Know Act and Underwriters Laboratories standards relate to other safety and health regulations, they do not specifically govern the transportation of refrigerants. Therefore, the emphasis is on the DOT as the authoritative body that sets the requirements for shipping these types of refrigerants through portable refillable tanks or containers.
