1. What is the primary purpose of EPA Section 608 certification?
A. To regulate the sale of gasoline
B. To control emissions of ozone-depleting refrigerants and certain substitutes
C. To regulate boiler pressure
D. To certify electrical contractors
Answer: To control emissions of ozone-depleting refrigerants and certain
substitutes
Rationale: EPA Section 608 establishes requirements for technicians who service,
maintain, repair, or dispose of appliances containing regulated refrigerants.
2. Which type of EPA Section 608 certification applies primarily to small
appliances?
A. Type I
B. Type II
C. Type III
D. Universal
Answer: Type I
Rationale: Type I certification is specifically for technicians who service small
appliances containing five pounds or less of refrigerant.
, 3. Under EPA Section 608, a small appliance generally contains how much
refrigerant?
A. More than 50 pounds
B. More than 25 pounds
C. Five pounds or less
D. Exactly 10 pounds
Answer: Five pounds or less
Rationale: EPA defines a small appliance as a hermetically sealed appliance
manufactured, charged, and sold with five pounds or less of refrigerant.
4. Which appliance is most likely classified as a small appliance?
A. Large supermarket rack system
B. Household refrigerator
C. Commercial chiller
D. Industrial process refrigeration system
Answer: Household refrigerator
Rationale: Household refrigerators are typical examples of small appliances
covered by Type I certification.
5. What does refrigerant recovery mean?
A. Burning refrigerant
B. Removing refrigerant from an appliance and storing it in an external container
C. Adding oil to a compressor
D. Filtering room air
Answer: Removing refrigerant from an appliance and storing it in an external
container
Rationale: Recovery removes refrigerant from an appliance and stores it without
necessarily processing or purifying the refrigerant.
, 6. What is refrigerant recycling?
A. Destroying refrigerant
B. Reprocessing refrigerant to remove contaminants such as oil and moisture
C. Replacing refrigerant with water
D. Venting refrigerant into the atmosphere
Answer: Reprocessing refrigerant to remove contaminants such as oil and
moisture
Rationale: Recycling involves processing recovered refrigerant to reduce
contaminants, generally for reuse.
7. What is refrigerant reclamation?
A. Releasing refrigerant into the atmosphere
B. Processing used refrigerant to meet specifications for new product
C. Mixing refrigerant with nitrogen
D. Removing refrigerant from an appliance without storing it
Answer: Processing used refrigerant to meet specifications for new product
Rationale: Reclamation requires processing refrigerant to meet recognized
purity specifications and is generally performed by an EPA-certified reclaimer.
8. Which refrigerant is commonly associated with older household
refrigerators?
A. R-12
B. R-410A
C. R-404A
D. R-507A
Answer: R-12
Rationale: R-12 was widely used in older domestic refrigerators and freezers
before being replaced by newer refrigerants.
, 9. Which refrigerant was commonly used in newer household refrigerators as
a replacement for R-12?
A. R-134a
B. R-11
C. R-113
D. R-502
Answer: R-134a
Rationale: R-134a became widely used in domestic refrigeration as a
replacement for CFC-12 (R-12).
10.Which refrigerant is classified as a CFC?
A. R-12
B. R-22
C. R-134a
D. R-410A
Answer: R-12
Rationale: R-12 is a chlorofluorocarbon (CFC) and has significant ozone-
depletion potential.
11.Which refrigerant is classified as an HCFC?
A. R-12
B. R-22
C. R-134a
D. R-744
Answer: R-22
Rationale: R-22 is a hydrochlorofluorocarbon (HCFC) that contains chlorine and
has ozone-depletion potential.
12.Which refrigerant is an HFC?
