QUESTION 1 What international environmental treaty signed in 1987
established the global framework for phasing out ozone-depleting
substances?
A. The Kyoto Protocol
B. The Montreal Protocol
C. The Paris Agreement
D. The Geneva Convention
Correct Answer: B. The Montreal Protocol
Detailed Rationale: The Montreal Protocol is an international
environmental treaty designed to protect the stratospheric ozone layer
by phasing out the production and consumption of ozone-depleting
substances such as CFCs and HCFCs.
QUESTION 2 Which section of the United States Clean Air Act governs
the national recycling and emission reduction program for refrigerants?
A. Section 111
B. Section 608
C. Section 504
D. Section 202
,Correct Answer: B. Section 608
Detailed Rationale: Clean Air Act Section 608 establishes regulations
regarding the handling, recovery, recycling, reclaiming, and safe
disposal of refrigerants used in stationary refrigeration and air
conditioning equipment.
QUESTION 3 What federal program evaluates and lists safe substitutes
for ozone-depleting substances to reduce overall risk to human health
and the environment?
A. The SNAP (Significant New Alternatives Policy) program
B. The OSHA Workplace Safety Program
C. The DOT Hazardous Materials Program
D. The ARI Equipment Testing Program
Correct Answer: A. The SNAP (Significant New Alternatives Policy)
program
Detailed Rationale: The EPA's SNAP program reviews and lists
acceptable and prohibited substitutes for ozone-depleting substances
across various industrial, commercial, and consumer applications.
QUESTION 4 What chemical compounds contain chlorine, fluorine, and
carbon, and possess the highest Ozone Depletion Potential (ODP)?
A. Hydrofluorocarbons (HFCs)
B. Hydrochlorofluorocarbons (HCFCs)
C. Chlorofluorocarbons (CFCs)
D. Hydrocarbons (HCs)
,Correct Answer: C. Chlorofluorocarbons (CFCs)
Detailed Rationale: CFCs contain chlorine atoms that migrate to the
stratosphere, where ultraviolet radiation breaks them down to destroy
ozone molecules, giving them very high ODP values.
QUESTION 5 What is the Ozone Depletion Potential (ODP) baseline
reference chemical assigned a standard rating of 1.0?
A. CFC-11
B. R-134a
C. Carbon dioxide
D. Helium
Correct Answer: A. CFC-11
Detailed Rationale: CFC-11 (trichlorofluoromethane) serves as the
primary baseline reference compound with an ODP rating of 1.0 against
which other ozone-depleting substances are measured.
QUESTION 6 What gas is used as the baseline reference for Global
Warming Potential (GWP) with an assigned value of 1?
A. Carbon dioxide (CO2)
B. CFC-11
C. Nitrogen
D. Methane
Correct Answer: A. Carbon dioxide (CO2)
, Detailed Rationale: Carbon dioxide has a GWP of 1 over a 100-year
horizon, serving as the benchmark for measuring the radiative forcing
impact of other greenhouse gases.
QUESTION 7 Under Clean Air Act Section 608 rules, what action is
strictly prohibited during the service, maintenance, repair, or disposal of
appliances?
A. Intentional venting or releasing of regulated refrigerants and their
substitutes
B. Reclaiming refrigerants through certified facilities
C. Storing recovered gases in approved cylinders
D. Transferring refrigerant between owners of the same equipment
Correct Answer: A. Intentional venting or releasing of regulated
refrigerants and their substitutes
Detailed Rationale: Federal law explicitly bans the intentional venting
of ozone-depleting refrigerants and most substitute refrigerants
(including HFCs and HFOs) into the atmosphere.
QUESTION 8 What type of release is defined as a small, unavoidable
loss that occurs despite best efforts during the connection or
disconnection of gauge hoses?
A. A catastrophic tank failure
B. A de minimis release
C. A major system breach
D. A process stub leak
Correct Answer: B. A de minimis release
