Which of the following statements about refrigerant recovery is TRUE according to EPA Section 609 regulations?

  1. AOnly certified technicians are permitted to purchase and handle refrigerants for MVAC systems.
  2. BRefrigerant can be vented to the atmosphere if the amount is less than 1 ounce (28 grams).
  3. CRefrigerant recovery cylinders can be filled to 100% of their liquid capacity.
  4. DRecovery equipment must be capable of recovering 95% of the refrigerant from a system.
Show answer & explanation

Correct answer: A. Only certified technicians are permitted to purchase and handle refrigerants for MVAC systems.

EPA Section 609 mandates that only technicians certified under this program are allowed to purchase and handle refrigerants for MVAC systems, emphasizing proper training and environmental protection.

Why the other options are wrong

  • B. It is illegal to vent ANY amount of refrigerant to the atmosphere, regardless of quantity.
  • C. Recovery cylinders must never be filled to 100% of their liquid capacity. They are typically filled to a maximum of 80% to allow for thermal expansion of the liquid refrigerant.
  • D. Recovery equipment must be able to recover at least 90% of the refrigerant when the compressor is operational, or 80% if the compressor is not operational. 95% is not the minimum standard.

EPA Section 609 Technician Certification

EPA Section 609 requires technicians to be certified to purchase and handle refrigerants for Motor Vehicle Air Conditioning (MVAC) systems.

  • Mandates training for proper refrigerant handling.
  • Prevents harmful release of refrigerants.
  • Applies to purchasing and servicing activities.
  • Protects ozone layer and reduces climate impact.

Memory trick: Certify to buy, or the air will cry.
