EPA 608 Type I study guide

EPA 608 Type I · Work through your exam, one topic at a time.

Section 608 Type I certification is one of four technician credentials created under Section 608 of the Clean Air Act, administered through 40 CFR Part 82, Subpart F, the National Recycling and Emission Reduction Program. The Type I credential is specifically for servicing small appliances. The underlying rule requires that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere be certified, and it prohibits intentionally venting ozone-depleting substances and their substitutes, such as hydrofluorocarbons, while maintaining, servicing, repairing, or disposing of air conditioning or refrigeration equipment. The regulation defines a technician as someone who attaches and detaches hoses and gauges to measure appliance pressure, adds or removes refrigerant, or performs any other activity that violates the integrity of an MVAC-like appliance or small appliance other than disposal. The EPA 608 Type I study guide has 4 sections and about 1,669 words.

01

Core: Section 608 Fundamentals, Venting Prohibition, and Refrigerant Handling

The Core domain tests the rules that apply to every refrigerant job under EPA Section 608: the venting prohibition, certification, refrigerant classes, recovery/recycling/reclamation, and safe cylinder handling. Expect definition and compliance questions rather than equipment-specific procedures.

Small Appliance Servicing and Disposal (Type I)

Type I tests appliances with 5 lb or less of refrigerant that are hermetically sealed and factory-charged: household refrigerators and freezers, room air conditioners, dehumidifiers, water coolers, and vending machines. The exam focuses on recovery targets, disposal, charging, and avoiding venting.

High- and Very High-Pressure Appliance Servicing and Disposal (Type II)

Type II covers high-pressure and very high-pressure appliances that are not small appliances and not MVACs: split systems, rooftop units, commercial refrigeration racks, and similar equipment using R-22, R-410A, R-134a, R-502, R-13, or R-23. The exam emphasizes evacuation levels, leak repair, pressure testing, and safe charging.

04

Low-Pressure Appliance Servicing and Disposal (Type III)

Type III covers low-pressure appliances, most often centrifugal chillers using R-11, R-123, or similar refrigerants. These systems normally operate below atmospheric pressure, so air and moisture can enter; the exam tests recovery, evacuation to 25 in Hg, purge units, leak detection, and charging safety.
