Who needs EPA 608 certification, and who does not
Certification is required of anyone who could reasonably be expected to violate the integrity of the refrigerant circuit while maintaining, servicing, repairing or disposing of an appliance containing a class I or class II refrigerant or a non-exempt substitute. Registered apprentices are exempt while closely and continually supervised. Disposal of small appliances, MVACs and MVAC-like appliances needs no certification. There is no education or experience prerequisite.
The trigger
Section 82.161(a)(1) applies to "any person who could be reasonably expected to violate the integrity of the refrigerant circuit" during maintenance, service, repair or disposal of an appliance containing a class I or class II refrigerant or a non-exempt substitute refrigerant. Since 1 January 2018 it has covered substitute refrigerants, not only CFCs and HCFCs.
EPA's plain-language version of who counts as a technician: attaching and detaching hoses and gauges to measure pressure; adding or removing refrigerant; or any other activity that violates the integrity of an MVAC-like appliance or a small appliance, other than disposal.
No prerequisites
There is no minimum age, no schooling requirement, no apprenticeship requirement and no experience requirement in the regulation. You pass the test, you are certified. That is unusual among the certifications in this portfolio and it is worth saying plainly.
Who is exempt
- Registered apprentices, under 82.161(a)(2) — exempt while closely and continually supervised by a certified technician. "Apprentice" is defined at 82.152 as someone currently registered with the US Department of Labor's Office of Apprenticeship or a recognised State Apprenticeship Council, and you can only be an apprentice for two years from the date you first register. Both the apprentice and the supervising technician are responsible for compliance.
- Anyone disposing of small appliances, MVACs or MVAC-like appliances — 82.161(a)(1)(vii) requires no certification for that disposal.
Related certifications that are not section 608
- MVAC — servicing motor vehicle air conditioners for consideration requires certification under 40 CFR part 82 subpart B (section 609), not section 608.
- MVAC-like appliances — Type II certification or subpart B certification. Either satisfies 82.161(a)(1)(v).
Keeping it
Under 82.161(a)(4) you must keep a copy of your certificate at your place of business, and retain it until three years after you stop operating as a technician. Under 82.161(a)(3) EPA may require you to demonstrate proper recovery and recycling procedures at your place of business; failing to demonstrate, or failing to use the equipment properly, can suspend or revoke the certificate. If it is revoked you must recertify before working on appliances again.
Since 1 January 2018, certifying programmes other than federally run ones must publish an online list of the technicians they have certified, updated at least annually, and must let technicians opt out of being listed.
