PART 1: CORE SECTION (QUESTIONS 1–25)
Q1. Which chemical element found in CFC and
HCFC refrigerants is primary responsible for
destroying the stratospheric ozone layer?
A) Fluorine
B) Hydrogen
C) Chlorine
D) Carbon
Answer: C) Chlorine
Rationale: When CFC or HCFC molecules break
down in the stratosphere, they release chlorine
radicals. A single chlorine atom can catalytically
destroy up to 100,000 ozone molecules over its
lifespan.
Q2. What is the Global Warming Potential (GWP)
baseline reference gas?
,A) Methane
B) Carbon Dioxide
C) R-22
D) R-410A
Answer: B) Carbon Dioxide
Rationale: Carbon dioxide (CO2) is established
as the baseline gas for measuring Global
Warming Potential and is assigned a GWP value
of 1. All other gases are measured relative to it.
Q3. Which type of refrigerant has the highest
Ozone Depletion Potential (ODP)?
A) HFCs
B) HFOs
C) HCFCs
D) CFCs
Answer: D) CFCs
Rationale: Chlorofluorocarbons (CFCs) contain
chlorine and lack hydrogen atoms, making them
highly stable. They reach the stratosphere fully
intact, resulting in the highest ODP.
Q4. Under EPA Section 608, what is the
maximum fine per day, per violation, for
releasing regulated refrigerants into the
atmosphere?
A) $10,000
B) $27,500
,C) over $44,000 (adjusted for inflation)
D) $100,000
Answer: C) over $44,000 (adjusted for inflation)
Rationale: The EPA adjusts statutory civil
penalties regularly for inflation. Violations of
Section 608 can result in severe financial
penalties exceeding $44,000 per day per
violation.
Q5. What standard color must a Department of
Transportation (DOT) approved refrigerant
recovery cylinder be?
A) Solid green
B) Gray body with a yellow top
C) Solid white
D) Blue body with a silver top
Answer: B) Gray body with a yellow top
Rationale: DOT safety regulations dictate that
recovery cylinders must feature a neutral gray
lower body and a bright yellow shoulder/top to
distinguish them from virgin cylinders.
Q6. To what maximum capacity can a refrigerant
recovery cylinder be safely filled with liquid?
A) 60% by weight
B) 70% by weight
C) 80% by weight
D) 95% by weight
, Answer: C) 80% by weight
Rationale: Cylinders must never be filled past
80% of their volume to leave a safety cushion for
liquid expansion caused by ambient temperature
increases. Overfilling can cause hydrostatic
rupture.
Q7. Which of the following is considered an
exempt refrigerant that can be legally vented
under Section 608?
A) R-22
B) R-410A
C) R-744 (Carbon Dioxide)
D) R-134a
Answer: C) R-744 (Carbon Dioxide)
Rationale: The EPA exempts certain natural
refrigerants like carbon dioxide (R-744), nitrogen,
and water from venting prohibitions because
they do not pose a significant threat to the
environment.
Q8. What does a "de minimis" release of
refrigerant mean?
A) An intentional release to clear lines
B) A major accidental spill
C) A minor, unavoidable release during normal
servicing adjustments
D) A release from a low-pressure purge unit
