EPA 609 Equipment & Certification Requirements 2 — Questions and Answers
Question 1: Recovery/recycling equipment must be tested and approved to what standard by the EPA?
- It only needs a manufacturer's label
- SAE J2788 (or J1990 for older R-12 equipment) (Correct answer)
- ISO 9001 quality management certification
- DOT transport certification
Correct answer: SAE J2788 (or J1990 for older R-12 equipment)
The EPA requires MVAC recovery/recycling equipment to be certified to SAE J2788 for R-134a (or J1990 for older R-12 use).
Question 2: What does refrigerant recovery equipment automatically prevent to protect the environment?
- Overcharging the system with refrigerant
- Refrigerant from being released to atmosphere during service (Correct answer)
- Oil from circulating back into the refrigerant
- UV dye from contaminating the refrigerant
Correct answer: Refrigerant from being released to atmosphere during service
Approved recovery equipment captures refrigerant before it can escape to the atmosphere, which is the core environmental requirement of Section 609.
Question 3: Service hoses used for R-1234yf systems are different from R-134a hoses in that they:
- Are color-coded red and blue like standard hoses
- Use unique quick-disconnect fittings to prevent cross-contamination between refrigerant types (Correct answer)
- Have no low-loss fittings
- Are made of standard rubber instead of barrier hose
Correct answer: Use unique quick-disconnect fittings to prevent cross-contamination between refrigerant types
R-1234yf service fittings are intentionally incompatible with R-134a equipment to prevent dangerous or illegal refrigerant mixing.
Question 4: What is the purpose of low-loss fittings on service hoses?
- To increase the flow rate during charging
- To minimize refrigerant release when connecting and disconnecting hoses (Correct answer)
- To prevent oil from entering the manifold gauges
- To lock the hose connections against theft
Correct answer: To minimize refrigerant release when connecting and disconnecting hoses
Low-loss fittings automatically close when disconnected from the system, minimizing the small amount of refrigerant released during service.
Question 5: Who is responsible for ensuring that Section 609 violations by employees are not occurring at an automotive repair shop?
- The individual certified technician only
- The EPA directly monitors all shops
- The shop owner and operators share responsibility with technicians (Correct answer)
- Only the state environmental agency
Correct answer: The shop owner and operators share responsibility with technicians
Both the shop owner/operators and individual technicians share legal responsibility for ensuring compliance with Section 609 regulations.
Question 6: A technician discovers that a colleague vented refrigerant intentionally. The technician should:
- Ignore it as an internal shop matter
- Report it to the EPA, which accepts tips about refrigerant violations (Correct answer)
- Help the colleague cover up the incident
- Only report it if the amount vented was more than 50 lbs
Correct answer: Report it to the EPA, which accepts tips about refrigerant violations
Intentional refrigerant venting is a federal violation and can be reported to the EPA; there is no minimum amount that makes venting legal.
