Section 608

Section 608 (together with Section 609, which covers motor vehicles) of the Clear Air Act (promulgated as 40 CFR Part 82) serves as the main form of occupational licensure for technicians in the HVAC industry in the United States, and satisfies the U.S. requirements under the Montreal Protocol. It requires that all persons who maintain, service, repair or dispose of appliances that contain regulated refrigerants be certified in proper refrigerant handling techniques. In particular, it helps regulate and minimize the release of refrigerants, and in particular ozone depleting refrigerants such as chloroflourocarbons and hydroflourocarbons, as well as other regulated refrigerants as determined by Section 612. rdf:langString
