What type of container must recovered refrigerant be stored in?
Answer: DOT-approved recovery cylinders that are clearly labeled
Recovered refrigerant must be stored in DOT-approved recovery cylinders that are properly labeled with the refrigerant type and recovery date.
Can R-134a and R-12 be mixed in the same recovery cylinder?
Answer: No — different refrigerants must NEVER be mixed
Mixing refrigerants creates a contaminated blend that is extremely difficult to separate and reclaim, and may damage the reclaimer's equipment.
What must technicians do if they discover that a vehicle's A/C system contains a refrigerant other than what is labeled?
Answer: Recover it into a separate cylinder for contaminated refrigerant
Unknown or mixed refrigerants must be recovered into a dedicated 'contaminated' or 'unknown' cylinder to prevent cross-contamination.
Recovery cylinders must be checked and retired when they reach:
Answer: Their retest date or show signs of damage/corrosion
DOT recovery cylinders must be hydrostatically retested periodically (typically every 5 years) and retired if damaged or past their retest date.
The maximum fill level for refrigerant recovery cylinders is:
Answer: 80% of water capacity by weight
Recovery cylinders must never be filled beyond 80% of their water capacity by weight to allow for refrigerant expansion.
Which equipment is required for MVAC refrigerant service under Section 609?
Answer: Recovery/recycling or recovery-only equipment certified to SAE J2788
Technicians must use recovery or recovery/recycling equipment that meets SAE J2788 certification to comply with EPA Section 609.
