1. Which federal agency enforces EPA Section 608 regulations?
A. OSHA
B. CDC
C. EPA
D. DOE
Rationale: The Environmental Protection Agency (EPA) administers and
enforces Section 608 of the Clean Air Act, which regulates the handling,
recovery, recycling, and disposal of refrigerants to reduce ozone
depletion and greenhouse gas emissions.
2. What is the primary purpose of EPA Section 608 certification?
A. To license electricians
,B. To certify plumbers
C. To ensure proper handling of refrigerants
D. To inspect boilers
Rationale: EPA Section 608 certification ensures technicians understand
safe and environmentally responsible refrigerant handling practices
required by federal law.
3. Which refrigerant has the highest ozone depletion potential?
A. R-410A
B. R-134a
C. R-11
D. R-32
Rationale: R-11, a chlorofluorocarbon (CFC), has one of the highest
ozone depletion potentials because it contains chlorine that destroys
stratospheric ozone.
4. Which refrigerants are classified as CFCs?
A. R-410A
,B. R-134a
C. R-12 and R-11
D. R-32
Rationale: R-11 and R-12 are CFC refrigerants containing chlorine,
making them highly damaging to the ozone layer.
5. HCFC refrigerants contain which element responsible for ozone
depletion?
A. Nitrogen
B. Hydrogen
C. Chlorine
D. Helium
Rationale: Chlorine atoms released from HCFC refrigerants contribute to
ozone depletion, although HCFCs are less harmful than CFCs.
6. Which refrigerant contains no chlorine?
A. R-22
B. R-11
, C. R-12
D. R-410A
Rationale: R-410A is an HFC refrigerant that contains no chlorine,
meaning it has zero ozone depletion potential.
7. What happens when ozone in the stratosphere is depleted?
A. Lower humidity
B. Cooler summers
C. More harmful ultraviolet radiation reaches Earth
D. Higher oxygen levels
Rationale: Ozone absorbs ultraviolet radiation. Reduced ozone allows
more UV rays to reach Earth's surface, increasing health and
environmental risks.
8. Which refrigerant type generally has zero ozone depletion
potential?
A. CFC
B. HCFC
