EPA 608 609 - EPA Refrigerant Handling Certification EPA 608 Certification Practice Test 1 — Questions and Answers
Question 1: Which EPA Section 608 certification type is required to service high-pressure systems such as those using R-22 or R-410A, excluding small appliances?
- Type I
- Type II (Correct answer)
- Type III
- Type IV
Correct answer: Type II
Type II certification covers high-pressure and very high-pressure appliances (those using refrigerants with normal boiling points above -50°C), excluding small appliances. R-22 and R-410A systems fall into this category.
Question 2: Which of the following refrigerants is most commonly associated with the low-pressure systems covered by EPA 608 Type III certification?
- R-22
- R-410A
- R-11 (Correct answer)
- R-134a
Correct answer: R-11
Type III certification covers low-pressure appliances, which use refrigerants that have boiling points above 10°C at atmospheric pressure. R-11 (CFC-11) is a classic example of a low-pressure refrigerant used in large centrifugal chillers.
Question 3: Under EPA Section 608, the prohibition on knowingly venting refrigerants during service, maintenance, repair, or disposal applies to which substances?
- CFCs only
- HCFCs only
- CFCs and HCFCs only
- CFCs, HCFCs, and their substitutes including HFCs (Correct answer)
Correct answer: CFCs, HCFCs, and their substitutes including HFCs
EPA extended the venting prohibition beyond CFCs and HCFCs to include substitute refrigerants such as HFCs (e.g., R-410A, R-134a). Knowingly venting any of these during service or disposal is illegal under Section 608.
Question 4: Under EPA Section 608, which individuals are legally permitted to purchase refrigerant in containers larger than 2 pounds?
- Any licensed HVAC business owner
- Any homeowner repairing their own equipment
- EPA Section 608 certified technicians only (Correct answer)
- Anyone holding a valid state mechanical license
Correct answer: EPA Section 608 certified technicians only
EPA regulations restrict the sale of refrigerant in containers larger than 2 pounds to technicians who have been certified under Section 608. This rule helps prevent unqualified handling and illegal venting of refrigerants.
Question 5: How long are owners of refrigerant recovery and recycling equipment required to retain service records under EPA Section 608?
- 1 year
- 2 years
- 3 years (Correct answer)
- 5 years
Correct answer: 3 years
EPA Section 608 requires that records related to refrigerant recovery, recycling, and reclamation activities be retained for a minimum of 3 years and be made available to EPA inspectors upon request.
Question 6: Which type of air conditioning system is regulated under EPA Section 609 rather than Section 608?
- Commercial refrigeration systems
- Residential central air systems
- Motor vehicle air conditioning (MVAC) systems (Correct answer)
- Industrial process refrigeration systems
Correct answer: Motor vehicle air conditioning (MVAC) systems
Motor vehicle air conditioning systems are governed by EPA Section 609, which has its own separate certification and equipment approval requirements. Section 608 covers stationary refrigeration and air conditioning equipment.
