Summary This chapter explained the role refrigerants play in ozone depletion, the Montreal Protocol, and consequent laws to protect the atmosphere. Sections 608 and 609 of the Clean Air Act were discussed, as well as penalties for intentionally venting refrigerants to the atmosphere. The Environmental Protection Agency’s responsibility for writing and enforcing the rules and regula- tions to prevent further ozone depletion by refrig- erants was also discussed. Proper service procedures when working with both old and new refrigerants have under- gone major changes. The new rules and proce- dures involving recovery, recycle, and reclaim activities were explained. This chapter also covered requirements and testing for technician certification in MVAC, Type I, Type II, Type III, and Universal categories. Equipment certification and step-by-step procedures for using recovery and recycle equip- ment were explained. Recovery cylinders are specially designed for use with R&R units. The proper and safe use of these recovery cylinders was fully explained. Finally, recycle equipment, recovery procedures, and capture methods were covered.
