What is the minimum amount of refrigerant in a container that requires the purchaser to be properly trained and 609 certified?

The minimum amount of refrigerant in a container that requires the purchaser to be properly trained and EPA 609 certified is indeed 20 pounds. This regulation is part of the effort to ensure that individuals handling refrigerants are knowledgeable about the environmental impacts and safe handling practices associated with these substances.

Refrigerants, particularly those that are classified as ozone-depleting substances or high-global warming potential gases, can have significant effects on the environment if not managed correctly. The EPA has implemented training and certification requirements specifically for individuals who handle such refrigerants in order to promote responsible usage and help reduce the risk of leaks or other environmental hazards.

When the container holds 20 pounds or more of refrigerant, it signifies a larger volume that could potentially lead to greater environmental harm if mishandled, thus necessitating that individuals are certified to handle such quantities safely. Containers with smaller amounts are considered less of a risk due to the reduced possibility of significant leaks or exposure.
