EPA 608 609 609 2 — Questions and Answers
Question 1: The EPA Section 609 certification specifically applies to technicians servicing which type of equipment?
- Motor vehicle air conditioning (MVAC) systems (Correct answer)
- Residential central air conditioners
- Commercial walk-in freezers
- Industrial chillers
Correct answer: Motor vehicle air conditioning (MVAC) systems
Section 609 certification covers technicians who repair or service motor vehicle air conditioning systems.
Question 2: Which refrigerant was the original standard in MVAC systems before being phased out due to ozone depletion?
- R-12 (CFC-12) (Correct answer)
- R-134a
- R-410A
- R-1234yf
Correct answer: R-12 (CFC-12)
R-12 was the original MVAC refrigerant and was phased out because CFCs deplete the ozone layer.
Question 3: When recovering refrigerant from an MVAC system, the equipment used must meet which SAE standard?
- SAE J2210 or J1991 for the appropriate refrigerant (Correct answer)
- OSHA 1910
- ASHRAE 15
- NFPA 70
Correct answer: SAE J2210 or J1991 for the appropriate refrigerant
MVAC recovery equipment must meet the applicable SAE standards such as J2210 for R-134a.
Question 4: What is the primary environmental concern that led to regulating CFC refrigerants under Section 609?
- Depletion of the stratospheric ozone layer (Correct answer)
- Increased smog formation
- Acid rain production
- Water table contamination
Correct answer: Depletion of the stratospheric ozone layer
CFCs release chlorine that destroys stratospheric ozone, which is why they are regulated.
Question 5: Under Section 609, who is required to be certified?
- Any person who repairs or services MVAC systems for consideration (Correct answer)
- Only vehicle owners
- Only refrigerant manufacturers
- Only EPA inspectors
Correct answer: Any person who repairs or services MVAC systems for consideration
Anyone servicing MVAC for payment must hold Section 609 certification.
Question 6: Which agency administers and enforces the Section 609 technician certification program?
- The U.S. Environmental Protection Agency (EPA) (Correct answer)
- The Department of Transportation
- OSHA
- The Department of Energy
Correct answer: The U.S. Environmental Protection Agency (EPA)
The EPA administers Section 609 certification under the Clean Air Act.
Question 7: Refrigerant recovered from an MVAC system may be returned to a vehicle only if it meets which requirement?
- It is recycled to SAE purity standards or recovered for reclamation (Correct answer)
- It is mixed with fresh oil
- It has been stored over 90 days
- It is vented and replaced
Correct answer: It is recycled to SAE purity standards or recovered for reclamation
Recovered refrigerant must be recycled to SAE purity standards before reuse in a vehicle.
