Core Section (Questions 1–25)
1. What is the primary cause of stratospheric ozone depletion?
a) Carbon dioxide emissions
b) Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs)
c) Nitrogen oxides
d) Sulfur dioxide
b) Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs)
Rationale: CFCs and HCFCs release chlorine and bromine, which catalytically destroy ozone
molecules in the stratosphere, per EPA findings.
2. What is the purpose of Section 608 of the Clean Air Act?
a) Regulate vehicle emissions
,b) Control refrigerant emissions to protect the ozone layer
c) Monitor industrial wastewater
d) Reduce greenhouse gas emissions
b) Control refrigerant emissions to protect the ozone layer
Rationale: Section 608 regulates refrigerant handling to minimize ozone depletion by
controlling emissions of ozone-depleting substances (ODS).
3. What is the ozone depletion potential (ODP) of R-134a?
a) High
b) Zero
c) Moderate
d) Very high
b) Zero
Rationale: R-134a, an HFC, contains no chlorine and thus has an ODP of zero, per EPA
standards.
4. Which refrigerant is classified as a Class I substance under the Montreal
Protocol?
a) R-410A
b) R-22
c) R-12
d) R-134a
c) R-12
Rationale: R-12, a CFC, is a Class I substance with high ODP, phased out under the Montreal
Protocol.
5. What is the penalty for intentionally venting refrigerants into the
atmosphere?
a) No penalty
b) Fines up to $50,000 per day and/or imprisonment
c) A warning only
d) Community service
b) Fines up to $50,000 per day and/or imprisonment
Rationale: Intentional venting violates Section 608, incurring fines up to $50,000 per day and
possible imprisonment, per EPA regulations.
6. What is the primary health risk associated with ozone depletion?
a) Respiratory infections
b) Increased risk of skin cancer and cataracts
c) Cardiovascular disease
d) Allergic reactions
b) Increased risk of skin cancer and cataracts
Rationale: Ozone depletion increases UV radiation, elevating risks of skin cancer and cataracts,
per EPA research.
, 7. What does the term "reclaim" mean in refrigerant management?
a) Reuse without processing
b) Process to meet new product standards
c) Dispose of refrigerant
d) Store indefinitely
b) Process to meet new product standards
Rationale: Reclaiming involves processing used refrigerant to meet purity standards for reuse,
per EPA guidelines.
8. Which is a substitute refrigerant for R-12 in many systems?
a) R-22
b) R-134a
c) R-410A
d) R-11
b) R-134a
Rationale: R-134a, an HFC, is a common substitute for R-12 due to its zero ODP, per EPA
standards.
9. What is required before disposing of an appliance with more than 5
pounds of refrigerant?
a) No action required
b) Recover refrigerant to EPA-specified levels
c) Vent refrigerant safely
d) Store refrigerant indefinitely
b) Recover refrigerant to EPA-specified levels
Rationale: EPA regulations require recovering refrigerant to specified levels before disposal to
prevent environmental harm.
10. What is the passing score for the EPA 608 Core exam in a proctored
setting?
a) 60%
b) 72%
c) 80%
d) 90%
b) 72%
Rationale: A minimum score of 72% (18/25 correct) is required to pass each section in a
proctored setting, per EPA standards.
11. Which gas contributes to ozone depletion in the stratosphere?
a) Carbon monoxide
b) Chlorine
c) Methane
d) Oxygen
b) Chlorine
Rationale: Chlorine, released from CFCs and HCFCs, destroys ozone molecules in the
stratosphere, per EPA research.
