Under EPA Section 608, which refrigerant must be recovered with equipment currently regulated by the certification requirements?

• A. R-134a
• B. R-22
• C. R-12
• D. R-410A

Answer: (C)

The main idea being tested is that refrigerant recovery must be done with equipment that is certified by the EPA for the refrigerant being recovered. R-12 is the refrigerant most closely tied to the EPA’s certification requirements under Section 608 because it’s a CFC with early, stringent controls due to its ozone-depleting potential. When servicing systems that contain R-12, you must use recovery equipment that is currently regulated and EPA-certified for that refrigerant. The other refrigerants listed are also subject to proper recovery, but the scenario highlighted by this rule points to R-12 as the example most directly governed by the certification framework.
