1. Which of these jobs calls for Type II certification under 40 CFR 82.161(a)(1)(ii)?

   A. Servicing a small applianceB. Servicing a high-pressure appliance other than a small appliance, an MVAC or an MVAC-like oneC. Servicing a low-pressure applianceD. Disposing of a small appliance, an MVAC or an MVAC-like appliance at the end of its working life

   Show the answer

   B. Servicing a high-pressure appliance other than a small appliance, an MVAC or an MVAC-like one

   Type II covers medium-, high- and very-high-pressure appliances, apart from small appliances, MVACs and MVAC-like appliances. Small appliances are Type I work (and disposing of one, or of an MVAC or MVAC-like appliance, needs no certification), and low-pressure appliances are Type III. 40 CFR 82.161(a)(1)(ii): “Persons who maintain, service, repair, or dispose of medium-, high-, or very high-pressure appliances (except small appliances, MVACs, and MVAC-like appliances) must be certified as Type II technicians.”

   Source: 40 CFR 82.161(a)(1)(ii)

2. A technician services MVAC-like appliances. Which certification does 40 CFR 82.161 accept for that work?

   A. Type I onlyB. Type III onlyC. Either Type II, or certification under 40 CFR part 82, subpart BD. None, because MVAC-like appliances are exempt from technician certification altogether

   Show the answer

   C. Either Type II, or certification under 40 CFR part 82, subpart B

   Servicing MVAC-like appliances can be covered either way: Type II, or the MVAC certification in subpart B. Only disposing of them needs no certification. 40 CFR 82.161(a)(1)(v): “Technicians who maintain, service, or repair MVAC-like appliances must either be certified as Type II technicians or be certified in accordance with 40 CFR part 82, subpart B”.

   Source: 40 CFR 82.161(a)(1)(v)

3. What kind of test must a technician pass to be certified as Type II?

   A. A closed-book, proctored test given in a secure environment by an EPA-approved certifying programB. A mail-in test in the same format some Type I programs offer, taken at home and sent back to the programC. An online test with notes allowedD. A hands-on demonstration, with no written test

   Show the answer

   A. A closed-book, proctored test given in a secure environment by an EPA-approved certifying program

   Only Type I programs may use the mail-in format. Type II and Type III need a closed-book, proctored test, and proctors must make sure no notes or training materials are used. Appendix D, section a: “Technicians must pass a closed-book, proctored test, administered in a secure environment, by an EPA-approved certifying program to be certified as a Type II or Type III technician.”

   Source: 40 CFR Part 82, Subpart F, Appendix D, section a (Test Preparation)

4. When people take certification tests at the same time at one site, how many registered proctors must the certifying program designate?

   A. At least one for every 25 peopleB. At least one for every 100 peopleC. One per site, however many are testingD. At least one for every 50 people

   Show the answer

   D. At least one for every 50 people

   Appendix D ties the number of proctors to the number testing at once: one for every 50. 25 and 100 are question counts, not proctor ratios. Appendix D, section b: programs must “designate at least one proctor registered for every 50 people taking tests at the same time at a given site”.

   Source: 40 CFR Part 82, Subpart F, Appendix D, section b (Proctoring)

5. The Type II part of the test is drawn from Group II. What kind of questions does Appendix D say Group II asks?

   A. Questions on business management, customer service and the paperwork a service company keeps for each job it doesB. Questions on laws and regulations onlyC. Sector-specific questions, in areas such as leak detection, recovery techniques, safety, shipping and disposalD. Questions on the environmental impact of refrigerants only

   Show the answer

   C. Sector-specific questions, in areas such as leak detection, recovery techniques, safety, shipping and disposal

   Group II is split by sector (Type I, Type II and Type III) and covers leak detection, recovery techniques, safety, shipping and disposal. Laws and regulations and environmental impact are Group I, core areas. Appendix D, section d: “Group II will ask questions covering sector-specific” issues in those five areas.

   Source: 40 CFR Part 82, Subpart F, Appendix D, section d (Test Content)

6. Under 40 CFR 82.157 as it reads today, which appliance must follow the Section 608 leak-repair requirements?

   A. A comfort-cooling appliance holding 60 pounds of R-22B. A comfort-cooling appliance holding 60 pounds of a substitute refrigerant onlyC. A commercial refrigeration appliance holding 30 pounds of R-22D. Any appliance with a full charge of 15 pounds or more

   Show the answer

   A. A comfort-cooling appliance holding 60 pounds of R-22

   Since April 10, 2020, Section 608 leak repair covers only large appliances using class I or class II refrigerant. R-22 is HCFC-22, which Appendix B to Subpart A of 40 CFR Part 82 lists as a class II controlled substance. 30 pounds is under the threshold, and 15 pounds is the separate 2024 HFC rule's figure. 40 CFR 82.157(a): “As of April 10, 2020, this section applies only to appliances with a full charge of 50 or more pounds of any class I or class II refrigerant or blend containing a class I or class II refrigerant.”

   Source: 40 CFR 82.157(a)

7. A 200-pound comfort-cooling appliance holds only a substitute refrigerant. Does 40 CFR 82.157 apply to it?

   A. Yes, because its 200-pound charge is far over the 50-pound full-charge threshold that 82.157 setsB. Yes, because comfort cooling always falls under 82.157C. No, because 82.157 doesn't apply to appliances containing solely substitute refrigerantsD. Yes, but only from January 1, 2026

   Show the answer

   C. No, because 82.157 doesn't apply to appliances containing solely substitute refrigerants

   Section 608 leak repair now reaches only appliances using class I or class II refrigerant, so the charge size doesn't bring this one in. A substitute-only appliance may fall under the separate 2024 HFC rule instead, which is where the January 1, 2026 date comes from. 40 CFR 82.157(a): “the requirements of this section do not apply to appliances containing solely substitute refrigerants.”

   Source: 40 CFR 82.157(a)

8. Unless a paragraph of 40 CFR 82.157 says otherwise, whom do its requirements apply to?

   A. The technician who last serviced the applianceB. The owner or operator of the applianceC. The refrigerant distributorD. The appliance manufacturer

   Show the answer

   B. The owner or operator of the appliance

   The leak-repair duties sit with the appliance's owner or operator unless a paragraph names someone else. Technicians, distributors and manufacturers aren't the default. 40 CFR 82.157(a): “Unless otherwise specified, the requirements of this section apply to the owner or operator of the appliance.”

   Source: 40 CFR 82.157(a)

9. A technician adds refrigerant to an appliance covered by 40 CFR 82.157. What must the technician do when the service is finished?

   A. Report the addition to EPA within 30 daysB. Repair every leak before leaving the siteC. Nothing, because recordkeeping is only the owner's jobD. Give the owner or operator documentation that meets the rule's requirements

   Show the answer

   D. Give the owner or operator documentation that meets the rule's requirements

   Whoever adds or removes refrigerant hands documentation to the owner or operator at the end of the job. Nothing in 82.157(b) sends it to EPA or makes the technician fix every leak on the spot. 40 CFR 82.157(b): “Persons adding or removing refrigerant from an appliance must, upon conclusion of that service, provide the owner or operator with documentation”.

   Source: 40 CFR 82.157(b)

10. How often must the owner or operator of an appliance covered by 40 CFR 82.157 calculate its leak rate?

    A. Every time refrigerant is added, apart from the exceptions the rule listsB. Once a yearC. Only when a technician reports a leak, or when the owner notices the charge running lowD. Once a month

    Show the answer

    A. Every time refrigerant is added, apart from the exceptions the rule lists

    The calculation is tied to each refrigerant addition, not to a calendar or a technician's report. 40 CFR 82.157(b): “The owner or operator must calculate the leak rate every time refrigerant is added to an appliance”, with a short list of exceptions.

    Source: 40 CFR 82.157(b)

11. A commercial refrigeration appliance is covered by 40 CFR 82.157. Above what leak rate must its owner repair leaks?

    A. 10 percentB. 15 percentC. 20 percentD. 30 percent

    Show the answer

    C. 20 percent

    Commercial refrigeration equipment has its own threshold in 82.157(c)(2). The other percentages either belong to other appliance categories or aren't leak rates in the rule. 40 CFR 82.157(c)(2)(i): “20 percent leak rate for commercial refrigeration equipment”.

    Source: 40 CFR 82.157(c)(2)

12. Which leak rate does 40 CFR 82.157 set for industrial process refrigeration equipment?

    A. 30 percentB. 20 percentC. 10 percentD. 50 percent

    Show the answer

    A. 30 percent

    Industrial process refrigeration gets the highest threshold in 82.157(c)(2). 50 percent isn't a rate in the rule, and the lower figures belong to other appliance categories. 40 CFR 82.157(c)(2)(ii): “30 percent leak rate for industrial process refrigeration equipment”.

    Source: 40 CFR 82.157(c)(2)

13. An office building's comfort-cooling appliance is covered by 40 CFR 82.157. Which leak rate applies to it?

    A. 20 percentB. 10 percentC. 30 percentD. 15 percent

    Show the answer

    B. 10 percent

    Comfort cooling shares the lowest threshold with other covered appliances outside the commercial and industrial process categories. The higher figures belong to those two categories, and 15 percent isn't a rate in the rule. 40 CFR 82.157(c)(2)(iii): “10 percent leak rate for comfort cooling appliances or other appliances with a full charge of 50 or more pounds of refrigerant”.

    Source: 40 CFR 82.157(c)(2)

14. Refrigerant is added to a covered appliance whose leak rate is over its threshold, and no industrial process shutdown is needed. How long does 40 CFR 82.157(d) allow to identify and repair the leaks?

    A. 7 daysB. 30 daysC. 120 daysD. One year

    Show the answer

    B. 30 days

    The standard deadline is 30 days from the refrigerant addition. The longer 120-day window applies only when an industrial process shutdown is required. 40 CFR 82.157(d): leaks must be identified and repaired “within 30 days (or 120 days if an industrial process shutdown is required)” of that addition.

    Source: 40 CFR 82.157(d)

15. An owner chose to repair a covered appliance but couldn't bring its leak rate below the threshold. What does 40 CFR 82.157(c)(1) require next?

    A. Pay a fixed penalty and keep operatingB. Top off the refrigerant every monthC. Create and implement a retrofit or retirement planD. Wait for the next scheduled inspection

    Show the answer

    C. Create and implement a retrofit or retirement plan

    When repair fails, the owner or operator moves to a retrofit or retirement plan under paragraphs (h) and (i). The rule offers no route that keeps a leaking appliance running on top-offs or a penalty. 40 CFR 82.157(c)(1): “the owner or operator must create and implement a retrofit or retirement plan”.

    Source: 40 CFR 82.157(c)(1)

16. EPA's fact sheet on its 2024 HFC rule sets out which appliances its leak-repair provisions reach. Which charge and refrigerant bring an appliance in?

    A. 50 pounds or more of any class I or class II refrigerant, or of a blend that contains a class I or class II refrigerantB. 15 pounds or more of a refrigerant that contains an HFC or an HFC substitute with a GWP greater than 53C. 5 pounds or more of any refrigerantD. 50 pounds or more of an HFC with a GWP greater than 150

    Show the answer

    B. 15 pounds or more of a refrigerant that contains an HFC or an HFC substitute with a GWP greater than 53

    The 2024 rule starts at 15 pounds and reaches HFCs and their substitutes above GWP 53, with compliance from January 1, 2026. 50 pounds of class I or class II refrigerant is the Section 608 threshold in 82.157. Fact sheet, Table 1: appliances “with a full charge of 15 pounds or more of a refrigerant that contains an HFC or a substitute for an HFC with a GWP greater than 53”.

    Source: EPA ER&R Program fact sheet (Sept. 20, 2024), Table 1: Leak Repair

17. According to EPA's fact sheet, which of these appliances does the 2024 HFC leak-repair rule leave out?

    A. Commercial refrigeration appliancesB. Industrial process refrigeration appliancesC. Comfort-cooling appliances in large buildingsD. Residential and light-commercial air conditioners and heat pumps

    Show the answer

    D. Residential and light-commercial air conditioners and heat pumps

    A footnote to Table 1 takes the residential and light-commercial air conditioning and heat pump sector out of the leak-repair provisions. Commercial refrigeration, industrial process refrigeration and comfort cooling all have leak-rate thresholds in that table. Fact sheet, Table 1, note b: “Appliances in the residential and light commercial air conditioning and heat pumps sector are not included in these provisions.”

    Source: EPA ER&R Program fact sheet (Sept. 20, 2024), Table 1: Leak Repair

18. A technician takes the Type II certification test. By when must the certifying program tell the technician the result?

    A. Within 7 days of the testB. Within 60 days of the testC. Within 30 days of the testD. Within 90 days of the test

    Show the answer

    C. Within 30 days of the test

    Appendix D gives certifying programs 30 days from the test date to report results. 7, 60 and 90 days don't appear in the grading rule. Appendix D, section e: “Certifying programs must inform the applicant of their test results no later than 30 days from the date of the test.”

    Source: 40 CFR Part 82, Subpart F, Appendix D, section e (Grading)

19. Where in the Code of Federal Regulations are the full requirements of EPA's 2024 HFC leak-repair program?

    A. 40 CFR 82.157B. 40 CFR Part 84, subpart CC. 40 CFR Part 82, subpart BD. 40 CFR Part 266, subpart Q

    Show the answer

    B. 40 CFR Part 84, subpart C

    EPA's fact sheet points to Part 84, subpart C. 82.157 now covers only class I and class II refrigerants, subpart B of Part 82 is where MVAC technician certification sits, and Part 266, subpart Q holds the RCRA alternative standards. Fact sheet: “Refer to 40 CFR part 84 subpart C for full requirements.”

20. Under EPA's 2024 HFC rule, which new commercial or industrial process refrigeration appliances containing an HFC must install and use automatic leak detection?

    A. Those with a full charge of 15 pounds or moreB. Those with a full charge of 50 pounds or moreC. Those with a full charge of 500 pounds or moreD. Those with a full charge of 1,500 pounds or more

    Show the answer

    D. Those with a full charge of 1,500 pounds or more

    Automatic leak detection is kept for the largest systems. 15 pounds is where the rule's leak-repair provisions start, 50 pounds is the Section 608 leak-repair threshold, and 500 pounds isn't a figure in Table 2, which sets 1,500 pounds for both new and existing appliances. Fact sheet, Table 2: appliances installed with a “full charge size of 1,500 pounds or more”.

    Source: EPA ER&R Program fact sheet (Sept. 20, 2024), Table 2: Automatic Leak Detection

21. Under EPA's 2024 HFC rule, how much virgin HFC may reclaimed HFC refrigerant contain?

    A. No more than 15%, by weightB. No more than 5%, by weightC. No more than 20%, by weightD. No more than 50%, by weight

    Show the answer

    A. No more than 15%, by weight

    Reclaimed HFC refrigerant may carry at most 15 percent virgin HFC by weight, and it must be labeled. 20 percent is a leak-rate figure, not a reclaim limit. Fact sheet, Table 3: “Reclaimed HFC refrigerants can contain no more than 15%”, by weight, of virgin HFCs.

    Source: EPA ER&R Program fact sheet (Sept. 20, 2024), Table 3: Reclaimed HFCs

22. Under the 2024 HFC rule's alternative method for disposable cylinders, to what vacuum does a Section 608 certified technician evacuate the cylinder before it goes to the final processor?

    A. 0 in-HgB. 10 in-HgC. 15 in-HgD. 29 in-Hg

    Show the answer

    C. 15 in-Hg

    The alternative method, from January 1, 2028, is a 15 in-Hg vacuum plus a certification statement given to the final processor. The other levels aren't part of the disposable-cylinder provision. Fact sheet, Table 5: a certified technician “evacuates a disposable cylinder to a vacuum level of 15 in-Hg”.

    Source: EPA ER&R Program fact sheet (Sept. 20, 2024), Table 5: Disposable Cylinders

23. Under EPA's RCRA alternative standards, what must a reclaimer that receives ignitable spent refrigerant from off-site for recycling maintain?

    A. A Type II certificate for each employeeB. EPA Clean Air Act section 608 certificationC. A local fire permit, and nothing elseD. Only a general business license

    Show the answer

    B. EPA Clean Air Act section 608 certification

    The reclaimer keeps its Section 608 certification, and the facility must also meet emergency preparedness and response requirements. Table 6 asks for no per-employee technician certificates. Fact sheet, Table 6: “The reclaimer must maintain EPA CAA section 608 certification”.

    Source: EPA ER&R Program fact sheet (Sept. 20, 2024), Table 6: RCRA Alternative Standards

24. Which of these refrigerant additions does 40 CFR 82.157(b) name as an exception to the leak-rate calculation?

    A. An addition of less than 5 poundsB. An addition made by the owner rather than a technicianC. An addition made during the first 30 days of the yearD. An addition made immediately following a retrofit

    Show the answer

    D. An addition made immediately following a retrofit

    Three additions are excused: one made right after a retrofit, one made on installing a new appliance, and one that qualifies as a seasonal variance. The rule has no small-quantity, calendar or who-did-it exception. 40 CFR 82.157(b): the calculation is required “unless the addition is made immediately following a retrofit, installation of a new appliance, or qualifies as a seasonal variance”.

    Source: 40 CFR 82.157(b)

25. A store's commercial refrigeration appliance holds 25 pounds of a refrigerant that contains an HFC and has a GWP greater than 53. It holds no class I or class II refrigerant. Which leak-repair rule covers it, and at what leak rate?

    A. Section 608 leak repair, 40 CFR 82.157, at 20%B. The 2024 HFC rule, at 20%C. The 2024 HFC rule, at 10%D. Neither, because the charge is under 50 pounds

    Show the answer

    B. The 2024 HFC rule, at 20%

    The appliance is over the HFC rule's 15-pound threshold, its refrigerant is above GWP 53, and it isn't residential or light-commercial air conditioning, so the 2024 rule applies at the commercial refrigeration rate. 82.157 doesn't reach it: it holds no class I or class II refrigerant and is under 50 pounds. 10% is the comfort-cooling rate. Fact sheet, Table 1: “Commercial refrigeration: 20%”.
