1. What is the primary purpose of EPA Section 609?
A. To regulate residential heating systems
B. To regulate motor vehicle air-conditioning refrigerant
handling
C. To regulate automotive engine oil
D. To regulate vehicle exhaust systems
Correct answer: B. To regulate motor vehicle air-conditioning
refrigerant handling
Rationale: Section 609 of the Clean Air Act establishes
requirements for servicing motor vehicle air-conditioning
(MVAC) systems and reducing refrigerant emissions.
2. A technician who services an MVAC system for payment
must generally be:
A. ASE certified only
B. Licensed as an electrician
C. Section 609 certified through an EPA-approved program
D. Certified under Section 608 only
Correct answer: C. Section 609 certified through an EPA-
approved program
,Rationale: Anyone repairing or servicing an MVAC system for
consideration must be properly trained and certified under
Section 609.
3. What does MVAC stand for?
A. Motor Vehicle Air Conditioning
B. Mechanical Vehicle Air Compressor
C. Motor Ventilation and Cooling
D. Mobile Vacuum Air Compressor
Correct answer: A. Motor Vehicle Air Conditioning
Rationale: MVAC refers to air-conditioning equipment installed
in motor vehicles.
4. Which federal agency administers the Section 609
requirements?
A. OSHA
B. EPA
C. FAA
D. DOT
Correct answer: B. EPA
Rationale: The U.S. Environmental Protection Agency
administers the relevant Clean Air Act refrigerant requirements.
,5. Why is refrigerant recovery important?
A. It increases engine horsepower
B. It prevents unnecessary release of refrigerant into the
atmosphere
C. It increases tire pressure
D. It eliminates the need for refrigerant
Correct answer: B. It prevents unnecessary release of refrigerant
into the atmosphere
Rationale: Recovery captures refrigerant so it can be recycled
or reclaimed instead of being released.
6. Which practice is prohibited when servicing most MVAC
refrigerants?
A. Recovery
B. Recycling
C. Intentional venting
D. Leak testing
Correct answer: C. Intentional venting
Rationale: Intentional release of regulated refrigerants during
servicing is prohibited, subject to specific regulatory exceptions.
7. What is the difference between recovery and recycling?
, A. Recovery removes refrigerant; recycling processes it for
reuse
B. Recovery destroys refrigerant; recycling vents it
C. Recovery adds refrigerant; recycling removes oil
D. There is no difference
Correct answer: A. Recovery removes refrigerant; recycling
processes it for reuse
Rationale: Recovery removes refrigerant from a system, while
recycling reduces contaminants so the refrigerant can
potentially be reused.
8. What does refrigerant reclamation generally involve?
A. Adding refrigerant oil
B. Processing recovered refrigerant to a specified purity
standard
C. Venting refrigerant
D. Mixing different refrigerants
Correct answer: B. Processing recovered refrigerant to a
specified purity standard
Rationale: Reclamation purifies recovered refrigerant to meet
applicable standards before reuse or resale. EPA notes
reclamation according to AHRI Standard 700.
