If a technician is trained and certified to handle HFC-134a, is further certification required for CFCs?

The correct choice is that further certification is not required for a technician already certified to handle HFC-134a to work with CFCs. This is due to the fact that the EPA 609 certification is designed to address the handling of various refrigerants, including both HFCs and CFCs, under the same guidelines.

Technicians who are certified to work with HFC-134a have received the necessary training on safe handling practices, environmental regulations, and recovery procedures that also apply to CFCs. Once certified, these technicians are allowed to work with multiple types of refrigerants without needing additional certifications as long as they operate within the regulations and guidelines set forth by the EPA.

Some may think further certification could be necessary due to differences in handling or restrictions associated with different refrigerants. However, the comprehensive training provided in the initial certification covers essential knowledge applicable across these refrigerant types. Therefore, technicians need not seek a separate certification specifically for CFCs if they are already qualified to handle HFCs.
