Attempt
Question 1:
What is the primary purpose of the EPA 608 certification?
a) To improve customer service skills
b) To ensure proper handling and disposal of refrigerants
c) To enhance electricity usage knowledge
d) To promote sales techniques
Correct Option: b) To ensure proper handling and disposal of refrigerants
Rationale: The EPA 608 certification is designed to certify HVAC technicians in the
proper handling and disposal of refrigerants to protect the environment.
Question 2:
Which of the following is considered a "high-pressure" refrigerant?
a) R-410A
b) R-22
c) R-134A
d) R-12
Correct Option: a) R-410A
Rationale: R-410A is classified as a high-pressure refrigerant, while R-22 and R-12 are
low-pressure, and R-134A is a medium-pressure refrigerant.
Question 3:
What is the main environmental concern related to refrigerants?
a) Noise pollution
b) Ozone depletion
c) Water contamination
d) Increased energy consumption
Correct Option: b) Ozone depletion
Rationale: Certain refrigerants, particularly CFCs and HCFCs, have been shown to
deplete the ozone layer, which is a major environmental concern.
, Question 4:
Which section of the Clean Air Act addresses refrigerant management?
a) Section 101
b) Section 112
c) Section 608
d) Section 609
Correct Option: c) Section 608
Rationale: Section 608 of the Clean Air Act specifically focuses on the management
and disposal of refrigerants to minimize environmental impact.
Question 5:
What is the maximum allowable leak rate for a Type I appliance?
a) 10%
b) 15%
c) 20%
d) 25%
Correct Option: b) 15%
Rationale: For Type I appliances, which include small appliances containing
refrigerants, the maximum allowable leak rate is 15%.

Which type of refrigerant is known for its high global warming potential (GWP)?
a) R-22
b) R-134A
c) R-410A
d) R-407C
Correct Option: b) R-134A
Rationale: R-134A has a high global warming potential compared to other refrigerants,
making it a concern for environmental regulations.
