  1. Q1Environmental impacts

    Chlorine atoms released in the stratosphere are the primary reason CFC refrigerants damage the ozone layer. What happens when ultraviolet radiation breaks down a CFC molecule?

    1. AIt releases hydrogen atoms that combine with oxygen to form acid rain over cities
    2. BIt releases chlorine atoms that catalytically destroy ozone
    3. CIt releases fluorine, which then reacts with water vapor in the upper atmosphere
    4. DIt releases carbon that forms carbon dioxide
    Show answer

    B. It releases chlorine atoms that catalytically destroy ozone In the stratosphere, strong UV light breaks CFC molecules apart and releases chlorine atoms. Each chlorine atom can catalytically destroy many ozone molecules before it leaves the stratosphere, which is why small CFC concentrations have an outsized effect on ozone. HFCs contain no chlorine, so their ozone-depletion potential is zero.

  2. Q2Environmental impacts

    A technician compares four refrigerants. Which statement correctly ranks ozone-depletion potential (ODP)?

    1. ACFCs are highest, then HCFCs, then HFCs
    2. BHCFCs are highest, then CFCs, then HFCs
    3. CHFCs are highest, then HCFCs, then CFCs
    4. DCFCs are highest, then HFCs, then HCFCs
    Show answer

    A. CFCs are highest, then HCFCs, then HFCs CFCs contain chlorine and have the highest ODP; CFC-11 and CFC-12 are about 1.0. HCFCs also contain chlorine but deplete ozone far less, with ODPs from about 0.01 to 0.1. HFCs contain no chlorine at all, so their ODP is zero. This ranking drives which refrigerants are phased out first.

  3. Q3Environmental impacts

    Which pairing correctly identifies a refrigerant's chemical family?

    1. AR-12 is an HFC
    2. BR-22 is an HCFC
    3. CR-134a is a CFC
    4. DR-22 is an HFC
    Show answer

    B. R-22 is an HCFC R-22 (HCFC-22) contains hydrogen, chlorine, fluorine, and carbon, making it an HCFC. R-12 is a CFC, and R-134a is an HFC that contains no chlorine. Recognizing the family matters because CFCs and HCFCs are ozone-depleting and are regulated differently from HFCs.

Study plan

How to pass the EPA Section 608 Technician Certification

The order that works: learn the rules, drill until they’re automatic, then use the exam simulator to check consistency.

  1. 1

    Universal = Core + Type I + Type II + Type III, 25 questions each

  2. 2

    Know the three R's — recover, recycle, reclaim — and when each applies

  3. 3

    Drill the leak-rate thresholds and repair timelines for high- and low-pressure systems

  4. 4

    Keep Type I small-appliance rules separate from Type II high-pressure and Type III low-pressure rules

EPA Section 608 Technician Certification FAQ

No. EPA does not run the exam or issue cards; EPA-approved certifying organizations administer it. These are original practice questions written from EPA's Test Topics and 40 CFR Part 82 Subpart F, not official or provider items.

The provider-standard format is 25 questions per section — Core, Type I, Type II, and Type III — with 70% to pass each section; Universal is 100 questions. EPA does not publish one national form, so confirm the exact format with your chosen EPA-approved provider.

Only for Universal certification. Type I covers small appliances, Type II high-pressure equipment, and Type III low-pressure equipment; each requires Core plus that type. The Core test must be proctored to count toward Universal.

No. EPA Section 608 certification does not expire, though you may need to replace a lost card through your certifying organization.

Yes. Open the exam simulator and sit a timed mock exam of 20 questions built from the free questions, once, with no signup. Unlocking the exam adds full-length runs of 100 questions in 100 minutes (a practice clock), as many as you like, each a new draw from the whole bank.

It splits the questions across the exam's areas using the weights EPA publishes, then picks questions inside each area, favouring ones you missed before and never repeating one within a run. A retake is a new draw, so you will meet different questions. It is a practice mock exam, not an official replica of the real exam.
