5 real sample questions

A large low-pressure chiller needs a shaft seal replacement, a common leak point on this equipment. What should happen first, before the seal is removed?

A. The refrigerant must be recovered to the required evacuation level before the seal area is opened

B. The building fire alarm should be manually triggered as a precaution

C. The refrigerant should be vented to reduce pressure before removing the seal

D. The chiller should be immediately scrapped rather than repaired

Show answer and reasoning

Correct answer: A. The refrigerant must be recovered to the required evacuation level before the seal area is opened

B: There is no fire alarm activation requirement tied to routine refrigerant recovery procedures.
C: Venting refrigerant to reduce pressure before repair is precisely the illegal act §82.154 prohibits; recovery equipment must be used instead.
D: A repairable leak does not automatically require scrapping the entire chiller; repair, following proper recovery procedure, is the appropriate response.

Source: 40 CFR 82.154; 40 CFR 82.156

Of recovery, recycling, and reclaiming, which one does NOT necessarily involve testing or processing the refrigerant at all?

A. Recovery

B. Recycling

C. Reclaiming

D. All three always require full AHRI 700 purity testing

Show answer and reasoning

Correct answer: A. Recovery

B: Recycling does involve processing (contaminant reduction via filter-driers), unlike recovery.
C: Reclaiming specifically requires full purity reprocessing to AHRI 700, the opposite of the answer being sought.
D: AHRI 700 purity testing is specific to reclaiming, not required for recovery or recycling.

Source: 40 CFR Part 82, Subpart F (recovery/recycling/reclaiming definitions)

What standard must recovery and/or recycling equipment be certified to under §82.158?

A. ARI/AHRI 740

B. AHRI 700

C. ISO 9001

D. NFPA 70

Show answer and reasoning

Correct answer: A. ARI/AHRI 740

B: AHRI 700 is the refrigerant purity standard used for reclaiming, not the equipment performance standard.
C: ISO 9001 is a general quality management standard, not the equipment standard specified in §82.158.
D: NFPA 70 is the National Electrical Code and unrelated to recovery equipment certification under Subpart F.

Why does the EPA regulate the handling of refrigerants under the Clean Air Act?

A. Refrigerants released to the atmosphere can deplete the stratospheric ozone layer or contribute to climate impact

B. Refrigerants are flammable and pose a fire code violation if not tracked

C. Refrigerant cylinders are considered hazardous waste containers under RCRA

D. Refrigerant sales generate excise tax revenue that must be reported to EPA

Show answer and reasoning

Correct answer: A. Refrigerants released to the atmosphere can deplete the stratospheric ozone layer or contribute to climate impact

B: Flammability is a separate safety concern from the ozone/climate rationale that actually underlies Subpart F.
C: Refrigerant cylinders are not regulated as RCRA hazardous waste containers under this program; the regulation is about emissions, not waste classification.
D: Subpart F is an emissions-reduction rule, not a tax-collection program.

Source: 40 CFR 82.150

A technician is recovering refrigerant from a system and a small puff escapes when disconnecting a hose despite proper procedure. Separately, a second technician opens a service valve to the atmosphere to empty a system faster instead of using recovery equipment. Which of these is a violation of §82.154?

A. Only the second technician's action, because opening a valve to the atmosphere to avoid recovery is a knowing vent, not a de minimis release

B. Only the first technician's action, because any escaping refrigerant is automatically a violation

C. Both actions are violations

D. Neither action is a violation because both technicians were performing service work

Show answer and reasoning

Correct answer: A. Only the second technician's action, because opening a valve to the atmosphere to avoid recovery is a knowing vent, not a de minimis release

B: Incidental releases during good-faith recovery are protected by the de minimis exception, so this is incorrect.
C: Both are not violations; the first technician's release is protected by the de minimis exception.
D: Performing service work does not exempt a technician from §82.154; the second technician's deliberate release is still a violation.
