EPA 608 (CORE) EXAM / NEWEST COMPLETE QUESTIONS
AND CORRECT VERIFIED ANSWERS (DETAILED ANSWERS)
ALREADY GRADED A+ 2025.
1
What is the purpose of the EPA Section 608 regulations?
A) To regulate the manufacturing of refrigerants.
B) To protect the stratospheric ozone layer by regulating refrigerants and
their handling.
C) To control the price of refrigerants.
D) To mandate the use of specific types of HVAC equipment.
E) To promote the use of CFCs.
Correct Answer: B) To protect the stratospheric ozone layer by
regulating refrigerants and their handling.
Rationale: EPA Section 608 of the Clean Air Act establishes
regulations for the handling of refrigerants (CFCs, HCFCs, HFCs,
etc.) to minimize their release into the atmosphere, which can
deplete the ozone layer.
2
Which of the following refrigerants is a Chlorofluorocarbon (CFC)?
A) R-22
B) R-134a
C) R-410A
D) R-12
E) R-404A
Correct Answer: D) R-12
Rationale: R-12 (Dichlorodifluoromethane) is a CFC, which has the
highest Ozone Depletion Potential (ODP) and is therefore banned for
production and import.
3
Which of the following refrigerants is a Hydrochlorofluorocarbon (HCFC)?
A) R-11
B) R-134a
,C) R-22
D) R-407C
E) R-410A
Correct Answer: C) R-22
Rationale: R-22 (Chlorodifluoromethane) is an HCFC. While it has a
lower ODP than CFCs, it still contributes to ozone depletion and its
production is being phased out.
4
Which of the following refrigerants is a Hydrofluorocarbon (HFC)?
A) R-11
B) R-12
C) R-22
D) R-134a
E) R-123
Correct Answer: D) R-134a
Rationale: R-134a (1,1,1,2-Tetrafluoroethane) is an HFC. HFCs have
zero ODP but have high Global Warming Potentials (GWP).
5
What is "Ozone Depletion Potential (ODP)"?
A) A measure of how much a refrigerant contributes to global warming.
B) A measure of a refrigerant's ability to destroy stratospheric ozone.
C) A measure of a refrigerant's flammability.
D) A measure of a refrigerant's toxicity.
E) A measure of a refrigerant's boiling point.
Correct Answer: B) A measure of a refrigerant's ability to destroy
stratospheric ozone.
Rationale: ODP is a numerical value assigned to a chemical to
indicate its relative potential for destroying the ozone layer. CFCs
have the highest ODP.
,6
What is "Global Warming Potential (GWP)"?
A) A measure of a refrigerant's ability to destroy stratospheric ozone.
B) A measure of how much a given mass of refrigerant contributes to global
warming over a given period compared to the same mass of carbon dioxide.
C) A measure of a refrigerant's flammability.
D) A measure of a refrigerant's toxicity.
E) A measure of a refrigerant's boiling point.
Correct Answer: B) A measure of how much a given mass of refrigerant
contributes to global warming over a given period compared to the
same mass of carbon dioxide.
Rationale: GWP is a relative measure of how much heat a greenhouse
gas traps in the atmosphere. HFCs have zero ODP but high GWP.
7
Which federal agency enforces the Clean Air Act, including Section 608
regulations?
A) Occupational Safety and Health Administration (OSHA).
B) Department of Energy (DOE).
C) Environmental Protection Agency (EPA).
D) Department of Transportation (DOT).
E) National Institute for Occupational Safety and Health (NIOSH).
Correct Answer: C) Environmental Protection Agency (EPA).
Rationale: The EPA is the federal agency responsible for enforcing
environmental laws, including the Clean Air Act and its Section 608
regulations concerning refrigerants.
8
What is required for technicians who maintain, service, repair, or dispose of
appliances that contain regulated refrigerants?
A) A high school diploma.
B) EPA Section 608 certification.
, C) A minimum of 5 years of experience.
D) Membership in a trade organization.
E) A bachelor's degree.
Correct Answer: B) EPA Section 608 certification.
Rationale: Federal law (EPA Section 608) requires all technicians who
handle regulated refrigerants to be certified.
9
What is the maximum penalty per day for violations of the Clean Air Act?
A) $1,000
B) $5,000
C) $10,000
D) $49,999
E)
100,000 CorrectAnswer : D ¿∗¿
49,999**
Rationale: The EPA can fine technicians up to $49,999 per day per
violation of the Clean Air Act, including Section 608 regulations.
10
Which of the following is considered a "regulated refrigerant" under EPA
Section 608?
A) Air
B) Nitrogen
C) Carbon Dioxide
D) R-134a
E) Water
Correct Answer: D) R-134a
Rationale: R-134a is an HFC and is a regulated refrigerant due to its
high GWP.
