EPA Section 608 Type II certification is the U.S. EPA credential required to service or dispose of medium-, high- and very-high-pressure stationary appliances, including residential and commercial air conditioning, heat pumps, and supermarket refrigeration. Technicians must pass the mandatory 25-question Core section plus a 25-question Type II section, each requiring 70% to pass, through an EPA-approved certifying organization. Type II content emphasizes high-pressure recovery and the Table 1 evacuation levels (high-pressure: 0 in Hg under 200 lb, 10 in Hg at 200 lb or more with post-1993 equipment; very-high-pressure 0 in Hg), leak-rate repair triggers (10% comfort cooling, 20% commercial, 30% industrial process) for 50-lb-plus ozone-depleting appliances and, under Part 84, 15-lb-plus HFC appliances, recovery equipment, and safe charging and service of refrigerants like R-22 and R-410A. Certification is mandated by the Clean Air Act and never expires. This free prep includes 178 research-based practice questions with explanations and an AI tutor.

Sample EPA 608 Type II Practice Questions

Try these sample questions to review concepts for the EPA 608 Type II exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 178+ question experience with AI tutoring.

1Under which federal law are the refrigerant recovery and recycling requirements enforced by the EPA Section 608 program established?
A.The Occupational Safety and Health Act
B.The Clean Air Act
C.The Resource Conservation and Recovery Act
D.The Toxic Substances Control Act
Explanation: Section 608 of the Clean Air Act (CAA) authorizes the EPA to establish regulations governing the use and disposal of ozone-depleting refrigerants and their substitutes. Technician certification, recovery requirements, and the venting prohibition all flow from the CAA.
2Which type of chlorine-containing compound is primarily responsible for the destruction of stratospheric ozone?
A.Carbon dioxide molecules released at ground level
B.Chlorine atoms freed from CFCs and HCFCs by UV light
C.Nitrogen gas released from agricultural fertilizer
D.Hydrogen released by fuel cells and refineries
Explanation: When CFC and HCFC molecules drift into the stratosphere, ultraviolet light breaks off chlorine atoms. A single chlorine atom can destroy tens of thousands of ozone molecules in a catalytic chain before it is removed, which is why chlorine-bearing refrigerants are phased out.
3The international agreement that schedules the phaseout of ozone-depleting substances worldwide is known as the:
A.Kyoto Protocol
B.Montreal Protocol
C.Paris Agreement
D.Geneva Convention
Explanation: The Montreal Protocol (1987) is the international treaty that phases out the production and consumption of ozone-depleting substances such as CFCs and HCFCs. Its later amendments, including the Kigali Amendment, also address high-GWP HFCs.
4What do the 'three R's' of responsible refrigerant management stand for?
A.Reduce, Reuse, Recycle
B.Recover, Recycle, Reclaim
C.Remove, Replace, Repair
D.Recharge, Restore, Retrofit
Explanation: Recover means to remove refrigerant from a system and store it in an external container. Recycle cleans it for reuse on site by removing oil and moisture. Reclaim processes it to meet the AHRI 700 purity standard so it can be resold.
5To be sold as 'reclaimed' refrigerant, the material must be processed to meet the purity specification of which standard?
A.ASHRAE Standard 15
B.AHRI Standard 700
C.UL Standard 1995
D.NFPA 70 (NEC)
Explanation: Refrigerant may be sold as reclaimed only after an EPA-certified reclaimer processes it to the purity specification in AHRI Standard 700. On-site recycling removes oil, moisture and acid but is not certified to that specification, so recycled refrigerant cannot be sold as reclaimed.
6Knowingly venting CFC and HCFC refrigerants during the maintenance, service, repair, or disposal of appliances is:
A.Permitted if the amount is under one pound
B.Prohibited by the Clean Air Act
C.Allowed only for residential systems
D.Permitted outdoors only
Explanation: Section 608(c)(1) of the Clean Air Act made knowingly venting class I and class II refrigerants unlawful on July 1, 1992, and Section 608(c)(2) extended the same prohibition to non-exempt substitutes on November 15, 1995. The only carve-out is a de minimis release during a good-faith attempt to recover or recycle.
7Which of the following releases is considered an allowable (de minimis) release and is NOT a violation of the venting prohibition?
A.Releasing refrigerant to the atmosphere to save time on a job
B.A small release while making or breaking connections during recovery
C.Venting a system to atmosphere before scrapping it
D.Discharging refrigerant to test a gauge manifold
Explanation: Under 40 CFR 82.154(a)(2) a de minimis release is not a violation when it happens during a good-faith attempt to recycle or recover refrigerant, using certified equipment, certified technicians and the required evacuation practices. Deliberate releases to save time, to scrap a unit, or to test tools are not de minimis.
8A technician who improperly vents refrigerant in violation of the Clean Air Act can be subject to fines of up to what amount per day, per violation?
A.$100 per day
B.Tens of thousands of dollars per day or more
C.$500 per day
D.There are no monetary penalties, only license suspension
Explanation: The Clean Air Act sets a civil penalty for each day of each violation, and the Federal Civil Penalties Inflation Adjustment Act requires EPA to raise that figure every year, so the published maximum in 40 CFR 19.4 now stands far above the 25,000 dollars originally written into the statute. The Act also authorizes an award of up to 10,000 dollars for information that leads to a penalty.
9Which Type of EPA Section 608 certification is required to service or dispose of high-pressure and very-high-pressure appliances?
A.Type I
B.Type II
C.Type III
D.Apprentice
Explanation: Under 40 CFR 82.161(a)(1)(ii), Type II certification covers persons who maintain, service, repair or dispose of medium-, high- and very high-pressure appliances, other than small appliances, MVACs and MVAC-like appliances. Type I covers small appliances and Type III covers low-pressure equipment.
10Which refrigerant is classified as a high-pressure refrigerant covered by Type II certification?
A.R-11
B.R-123
C.R-22
D.R-113
Explanation: R-22 (an HCFC) is a high-pressure refrigerant historically used in air conditioning and refrigeration and falls under Type II. R-11, R-123, and R-113 are low-pressure refrigerants associated with Type III chillers.
