The EPA certification, also known as the 608 certification, is a crucial qualification for professionals working with equipment containing ozone-depleting substances (ODS). It is required by the Clean Air Act and consists of four different levels: Type I, Type II, Type III, and Universal. Roles that benefit from this certification include HVAC techs, electricians, and other technicians. The certification is obtained by passing a core test and a specific certification type test, covering topics such as environmental impact, regulations, and safety measures.
