Core — Shipping, Recordkeeping and Regulations — HVAC: EPA 608 Tech Cert practice questions

A technician certified several years ago asks whether the credential must be renewed. The BEST response is that the certification:

1. Expires after five years and requires a full retest
2. Does not expire, though it may be revoked for violations
3. Must be renewed each time a new refrigerant is introduced
4. Transfers to the employer and lapses if the technician moves

Answer: B — Does not expire, though it may be revoked for violations

B) Correct — the certification is issued to the individual and does not expire, but EPA may revoke it as an enforcement action. A) borrows a renewal cycle from other trade credentials. C) confuses product changes with credential status. D) reverses ownership; the certification belongs to the person, not the shop.

Which statement about leak repair obligations is MOST accurate for a technician to give a customer?

1. The trigger leak rate is identical for every appliance category
2. The trigger rate depends on how the appliance is categorized
3. Any leak of any size must be repaired within twenty-four hours
4. Leak rules apply only to systems using ozone-depleting refrigerant

Answer: B — The trigger rate depends on how the appliance is categorized

B) Correct — the leak rate that triggers mandatory repair varies by appliance category, such as commercial refrigeration versus comfort cooling, so the technician must apply the level set for that equipment. A) oversimplifies into a single number that does not exist. C) invents a deadline and ignores that the rules key on rate, not on any detectable leak. D) is outdated; the requirements extend to substitute refrigerants as well.

Section 609 covers refrigerant work on:

1. Low-pressure chillers
2. Motor vehicle air conditioning (MVAC)
3. Supermarket refrigeration
4. Residential split systems

Answer: B — Motor vehicle air conditioning (MVAC)

A) Type III, Section 608. B) Correct — Section 609 governs MVAC servicing; small-can sales rules and tech cert exist under that section. C) Section 608 Type II. D) Section 608 Type II.

Which is true regarding selling refrigerant to a homeowner without certification?

1. Permitted for systems under 5 lbs charge
2. Prohibited for all refrigerants except R-410A
3. Permitted for any HFC because HFCs are unregulated
4. Permitted only for hermetically sealed appliances such as small DIY R-134a auto cans at retail

Answer: D — Permitted only for hermetically sealed appliances such as small DIY R-134a auto cans at retail

A) Charge size is irrelevant to the sales restriction. D) Correct — sales of non-exempt refrigerants are restricted to 608-certified technicians; the narrow retail exception covers Section 609 small-can sales for MVAC. C) HFCs are regulated under Section 608 since 2018 and AIM Act. B) R-410A is restricted-sale.

Which body REGULATES refrigerant management under federal law?

1. OSHA
2. NIOSH
3. UL
4. EPA

Answer: D — EPA

A) OSHA regulates worker exposure and PPE, not refrigerant venting. D) Correct — EPA implements Section 608 of the Clean Air Act. C) UL is a private equipment safety listing body. B) NIOSH researches and recommends exposure limits but does not enforce 608.

Service records documenting refrigerant added, recovered, and disposed must be retained for at least:

1. 1 year
2. 10 years
3. 5 years
4. 3 years

Answer: D — 3 years

A) Too short for federal rule. D) Correct — 40 CFR Part 82 requires service and disposal records be kept at least 3 years. C) DOT cylinder retest interval, not recordkeeping. B) Not the federal minimum.

Civil penalties for venting a regulated refrigerant can reach up to (per day, per violation, adjusted for inflation):

1. $100
2. $1,000
3. Tens of thousands of dollars (over $46,000 per day, per violation)
4. Penalties were eliminated in 2015

Answer: C — Tens of thousands of dollars (over $46,000 per day, per violation)

A/B) Far too low. C) Correct — Clean Air Act penalties exceed $46,000/day/violation as inflation-adjusted; bounty programs allow informants to be paid. D) Penalties remain in force.

An owner operates a chiller that holds well above the regulatory size threshold for leak requirements. When refrigerant is added, what must be documented?

1. Only the total dollar cost of the refrigerant purchased
2. Only the name of the technician who performed the work
3. Nothing, because service records are voluntary for owners
4. The date, refrigerant type and amount added to the unit

Answer: D — The date, refrigerant type and amount added to the unit

D) Correct — servicing records for larger appliances must capture when refrigerant was added and how much, because that history is what reveals a developing leak. A) is a business record, not a refrigerant record. B) is part of a complete record but by itself does not track the charge. C) reverses the rule; recordkeeping is mandatory for owners of appliances above the size threshold.

After Nov 14, 1994, who can purchase regulated refrigerants?

1. Anyone
2. Only EPA-certified technicians (or certain entities)
3. Only contractors
4. Only equipment owners

Answer: B — Only EPA-certified technicians (or certain entities)

A) Public can't buy. B) Correct — EPA Section 608 cert required for purchase of most regulated refrigerants. C) Cert needed in addition. D) Owners typically can't buy regulated refrigerant directly.

A technician services a 15-ton rooftop unit and adds refrigerant. Which record is the technician's own obligation to be able to produce?

1. The building owner's utility bills for the prior year
2. Proof of technician certification for that appliance type
3. The manufacturer's original engineering drawings for the unit
4. A municipal permit authorizing refrigerant transfer on site

Answer: B — Proof of technician certification for that appliance type

B) Correct — a certified technician must hold and be able to produce evidence of certification for the appliance type being serviced. A) is unrelated to refrigerant regulation. C) may help diagnosis but is not a regulatory record the technician must keep. D) invents a permit requirement that does not exist for ordinary refrigerant service.
