EPA 608 609 - EPA Refrigerant Handling Certification EPA 608 Certification Practice Test 1

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?

Accepted Answer

Type II

Answer

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?

Accepted Answer

R-11

Answer

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?

Accepted Answer

CFCs, HCFCs, and their substitutes including HFCs

Answer

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?

Accepted Answer

EPA Section 608 certified technicians only

Answer

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?

Accepted Answer

3 years

Answer

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.
