MASTERY
Question 1:
What is the primary purpose of the EPA 608 Certification?
A) To ensure technicians are qualified to work on high-pressure systems
B) To regulate the sale and disposal of refrigerants
C) To establish standards for refrigerant handling and safety
D) To certify energy efficiency in HVAC systems
CORRECT OPTION: C
RATIONALE: The EPA 608 Certification establishes protocols for the safe handling,
recovery, and recycling of refrigerants in order to protect the environment.
Question 2:
Which refrigerant is classified as a CFC?
A) R-410A
B) R-12
C) R-22
D) R-134A
CORRECT OPTION: B
RATIONALE: R-12 is a chlorofluorocarbon (CFC) and has been phased out due to its ozone
depletion potential.
Question 3:
, What is the minimum percentage of refrigerant that must be recovered from a system
before disposal?
A) 50%
B) 80%
C) 100%
D) 90%
CORRECT OPTION: C
RATIONALE: Regulations require that 100% of refrigerant be recovered from appliances
before they can be disposed of, to prevent environmental damage.
Question 4:
What is the primary component used for detecting refrigerant leaks?
A) Pressure gauge
B) Thermometer
C) Electronic leak detector
D) Manifold gauge
CORRECT OPTION: C
RATIONALE: Electronic leak detectors are specifically designed to find refrigerant leaks by
detecting the presence of refrigerant vapor.
Question 5:
Which type of refrigerant is known for being environmentally friendly?
A) CFCs
B) HFOs
C) HCFCs
D) HFCs
CORRECT OPTION: B
RATIONALE: Hydrofluoroolefins (HFOs) have low global warming potential and are
considered more environmentally friendly than traditional refrigerants.
Question 6:
When recovering refrigerants, what safety equipment should be worn?
