EPA Certification Exam Latest 2026 Actual Exam|
Complete 200 Real Exam Questions and Correct
Verified Answers/ Graded A+ (New!!)
1. What is the primary environmental concern associated with
CFC and HCFC refrigerants?
A. Global warming only
B. Depletion of the stratospheric ozone layer
C. Acid rain formation
D. Groundwater contamination
Answer: B
Rationale: CFCs and HCFCs contain chlorine, which rises to the
stratosphere and catalytically destroys ozone molecules when
exposed to UV radiation. The ozone layer protects life on Earth
from harmful UV-B radiation.

,2. Under Section 608 of the Clean Air Act, which of the
following is prohibited?
A. Recovering refrigerant for reuse
B. Knowingly releasing refrigerants into the atmosphere
C. Using EPA-certified recovery equipment
D. Recycling refrigerant on-site
Answer: B
Rationale: Section 608 prohibits the intentional release (venting)
of any refrigerant during maintenance, service, repair, or
disposal of appliances. Violations carry significant penalties.
3. Which refrigerant classification indicates "non-toxic and
non-flammable"?
A. A1
B. A2
C. B1
D. B3
2
,Answer: A
Rationale: The ASHRAE Standard 34 safety classification uses
two digits: the first (A or B) indicates toxicity (A = lower toxicity,
B = higher toxicity); the second (1, 2, or 3) indicates flammability
(1 = no flame propagation). A1 is the safest category.
4. What is the ozone depletion potential (ODP) of HFC
refrigerants such as R-134a and R-410A?
A. High (greater than 1.0)
B. Moderate (0.5 to 1.0)
C. Low (0.01 to 0.5)
D. Zero (0.0)
Answer: D
Rationale: HFCs (hydrofluorocarbons) contain no chlorine, only
hydrogen, fluorine, and carbon. They have zero ozone depletion
potential, though they may have high global warming potential
(GWP).
3
, 5. Which international treaty phased out the production of
CFCs and HCFCs?
A. Kyoto Protocol
B. Paris Agreement
C. Montreal Protocol
D. Basel Convention
Answer: C
Rationale: The Montreal Protocol on Substances that Deplete the
Ozone Layer (1987) is the international agreement that phased
out production of ozone-depleting substances including CFCs and
HCFCs.
6. What does the acronym SNAP stand for in EPA regulations?
A. System for National Appliance Protection
B. Significant New Alternatives Policy
C. Safety Notification for Appliance Professionals
D. Standard for Natural Air Pollution
