What is the primary goal of refrigerant recovery procedures?
Refrigerant recovery aims to prevent the release of harmful gases into the atmosphere and to ensure proper disposal or reuse.
Which equipment is essential for performing refrigerant recovery?
Recovery machines are used to safely extract refrigerants from HVAC systems without releasing them into the environment.
When should refrigerant be recovered from an HVAC system?
Recovery must be performed before opening a system to prevent refrigerant emissions and comply with environmental regulations.
Why is it important to use certified recovery cylinders?
Certified recovery cylinders are designed to handle high pressures and meet safety standards for refrigerant storage and transport.
What is a common mistake during refrigerant recovery?
Not evacuating hoses and equipment can cause cross-contamination of refrigerants and reduce recovery efficiency.
Why should recovered refrigerant be labeled clearly?
Proper labeling prevents the accidental use of contaminated or incorrect refrigerant types in other systems.

Which refrigerants must be recovered according to EPA regulations?
The EPA mandates recovery for all CFCs, HCFCs, and HFCs to reduce ozone depletion and global warming potential.
What safety gear is recommended during refrigerant recovery?
Wearing goggles and gloves protects technicians from frostbite and exposure to high-pressure refrigerants.
What should be done if the refrigerant is suspected to be contaminated?
Contaminated refrigerants must be sent to a reclamation facility and must not be reused until tested and cleaned.
