EPA 608 Type I case studies
EPA 608 Type I · Put your knowledge to work in context.
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 case studies are 5 cases and about 2,339 words.
