EPA 609 regulates regulations for refrigerant handling and recovery.

• A. EPA 609
• B. OSHA Part 1910
• C. ISO 9001
• D. FMVSS 108

Answer: (A)

Refrigerant handling and recovery are regulated by the EPA under 609 of the Clean Air Act. This rule requires technicians who service motor vehicle air conditioning systems to be certified and sets requirements for recovering refrigerants to prevent their release into the atmosphere. It’s specifically aimed at protecting the environment by stopping venting of refrigerants and outlining compliance rules. The other options address different areas: OSHA Part 1910 covers general workplace safety, ISO 9001 focuses on quality management systems, and FMVSS 108 deals with vehicle lighting and signaling standards. EPA 609 directly governs refrigerant handling and recovery.
