Chlorofluorocarbon (CFC) Refrigerant Handling

Chlorofluorocarbons were once the dominant refrigerants in cooling and air-conditioning systems, but their role in stratospheric ozone depletion led to their phase-out under the Montreal Protocol. Legacy equipment and stocks remain in service, and technicians must handle them in a manner that prevents release and complies with environmental law. This course explains the chemistry, properties, and environmental effects of CFCs and their replacements, and develops sound practice in recovery, recycling, leak detection, charging, and cylinder handling. United States requirements under Section 608 of the Clean Air Act are addressed throughout.

Who Should Attend

• HVAC and refrigeration technicians
• Facility maintenance personnel servicing chillers and cooling equipment
• Environmental and compliance staff in industrial and commercial facilities
• Technicians preparing for EPA Section 608 certification examinations

Learning Outcomes

• Describe the molecular structure, nomenclature, and properties of CFC, HCFC, HFC, and HFO refrigerants
• Explain the mechanism of ozone depletion and the concepts of ODP and GWP
• Summarize the obligations of the Montreal Protocol and EPA regulations under 40 CFR Part 82, Subpart F
• Perform refrigerant recovery, recycling, and evacuation using correct procedures
• Apply safe handling, storage, and labeling practices for refrigerant cylinders
• Identify refrigerant safety classifications according to ASHRAE Standard 34

Assessment & Certification

Candidate competence is evaluated through a written examination and a practical assessment of refrigerant recovery and cylinder handling. Successful candidates receive an IIME Certificate of Training bearing a unique verification code that can be confirmed online. The program comprises 32 contact hours (4 days). The IIME Certificate of Training does not replace EPA Section 608 technician certification, which is issued only through EPA-approved certifying organizations.
