EPA Section 608 Type II certification is the U.S. EPA credential required to service or dispose of high-pressure 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 required evacuation table (10 in Hg under 200 lbs, 15 in Hg at 200 lbs or more, 0 psig for very-high-pressure), leak-rate repair thresholds for 50-lb-plus appliances (10% comfort cooling, 20% commercial, 30% industrial process), 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 100 research-based practice questions with explanations and an AI tutor.

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 released at ground level

B.Chlorine atoms released when CFCs and HCFCs break down in the stratosphere

C.Nitrogen released from fertilizer

D.Hydrogen released from fuel cells

Explanation: When CFC and HCFC molecules reach the stratosphere, ultraviolet radiation frees chlorine atoms. A single chlorine atom can destroy many thousands of ozone molecules in a catalytic chain reaction, which is why these refrigerants are being 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 15

B.AHRI Standard 700

C.UL 1995

D.NFPA 70

Explanation: Reclaimed refrigerant must be processed to the purity level specified in AHRI Standard 700 and may only be performed by an EPA-certified reclaimer. Recycling on site does not meet this standard, so recycled refrigerant cannot be sold as reclaimed.

6Since November 15, 1995, knowingly 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: The Clean Air Act prohibits knowingly venting CFC and HCFC refrigerants (and, since 2016, most HFC substitutes) during service or disposal. Only de minimis releases that occur during good-faith recovery are exempt; there is no one-pound or outdoor allowance.

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 speed up a job

B.A small refrigerant release that occurs during good-faith attempts to recover the refrigerant

C.Venting a system before disposal

D.Discharging refrigerant to test a gauge

Explanation: De minimis releases that occur during the good-faith making or breaking of connections while recovering refrigerant are not violations. Purposeful releases to save time, to dispose, or to test equipment are prohibited.

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

C.$500 per day

D.There are no monetary penalties, only license suspension

Explanation: The Clean Air Act authorizes substantial civil penalties (tens of thousands of dollars per day, per violation, adjusted for inflation) for illegal venting. The EPA can also pay a reward to citizens who supply information leading 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: Type II certification covers high-pressure and very-high-pressure appliances such as residential and commercial air conditioning, heat pumps, and supermarket systems. Type I covers small appliances and Type III covers low-pressure (chiller) 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.

EPA 608 Type II Study Tips from Top Performers

1Memorize the required evacuation table cold: under 200 lbs = 10 in Hg, 200 lbs or more = 15 in Hg (post-1993 equipment), very-high-pressure = 0 psig

2Lock in the leak-rate thresholds for 50-lb-plus appliances: 10% comfort cooling, 20% commercial refrigeration, 30% industrial process refrigeration

3Know the difference between system-dependent (passive, 15 lbs or less) and self-contained (active) recovery equipment

4Understand the three R's precisely: recover, recycle (on-site), and reclaim (to AHRI 700 by a certified reclaimer)

5Study high-pressure refrigerant specifics: R-22 vs R-410A pressures, charging blends as liquid to avoid fractionation, and POE oil moisture control

Frequently Asked Questions

What does EPA 608 Type II certification allow me to do?

Type II certification authorizes you to service, maintain, and dispose of high-pressure and very-high-pressure stationary appliances such as residential and commercial air conditioning, heat pumps, and supermarket refrigeration. It covers refrigerants like R-22 and R-410A.

How many questions are on the EPA 608 Type II exam and what score do I need?

You take the mandatory 25-question Core section plus a 25-question Type II section. You must score at least 70% on each section to earn Type II certification through an EPA-approved certifying organization.

What are the required evacuation levels for high-pressure appliances?

Using post-November 15, 1993 recovery equipment, a high-pressure appliance under 200 lbs must be evacuated to 10 inches Hg vacuum, and one of 200 lbs or more to 15 inches Hg, before a major repair. Very-high-pressure appliances only need 0 psig.

What are the leak-rate repair thresholds I need to know?

For appliances containing 50 lbs or more, leaks must be repaired when the annual leak rate exceeds 10% for comfort cooling, 20% for commercial refrigeration, and 30% for industrial process refrigeration, generally within 30 days.

Does EPA 608 Type II certification expire?

No. Section 608 technician certification does not expire and is valid for your lifetime. There is no periodic renewal or re-testing requirement, and the certification stays with you regardless of employer.
