Section 608 regulations apply to which types of refrigerants?

• A. HFCs only
• B. CFC, HCFC, HFC
• C. CFCs only
• D. HCFCs only

Answer: (B)

Section 608 covers how technicians must handle refrigerants during service, recovery, disposal, and recycling to prevent releases. It applies to the refrigerants used in a wide range of equipment, including CFCs, HCFCs, and HFCs. That means any system containing these refrigerants—past or present—falls under these rules, with requirements like proper recovery equipment, prohibition on venting, and EPA-certified technicians. The other options are too narrow because focusing only on one group would miss the other refrigerant classes that are also regulated. Even though HFCs don’t deplete the ozone, Section 608 governs their handling due to environmental protection concerns and the need to control refrigerant emissions across all these families.
