The sale of CFC and HCFC refrigerants is restricted to whom?

The sale of CFC (chlorofluorocarbons) and HCFC (hydrochlorofluorocarbons) refrigerants is restricted specifically to technicians who are EPA certified in refrigerant recovery. This regulation is in place because CFCs and HCFCs are ozone-depleting substances, and their handling requires specialized knowledge and training to prevent environmental damage. Technicians with the necessary certification are trained to manage and recover these substances safely, ensuring compliance with environmental regulations.

Individuals without the necessary training may not understand the proper procedures for handling, storing, or disposing of these refrigerants, which could lead to environmental harm. Therefore, the certification acts as a safeguard, allowing only those with verified knowledge and skills to legally purchase and handle these substances.

The other options involve individuals or entities that do not have the specific training and certification required, thus lacking permission to handle these regulated substances safely.
