Clean Air Act

Under this act, the EPA (Environmental Protection Agency) has established requirements preventing the release of ozone-depleting substances. Section 608 of the Clean Air Act addresses the stationary aspect of the heating, ventilation, air conditioning and refrigeration industry. Section 609 deals with the mobile, motor vehicle air conditioning industry. Technicians who violate the provisions of the Clean Air Act may be subject to fines, loss of certification, and may be required to appear in Federal court.

Section 608

All individuals who maintain, service, repair or dispose of appliances containing regulated refrigerants must be certified in proper handling techniques as required under the Federal Clean Air Act. The EPA limits the sale of regulated refrigerants to certified technicians.

The Section 608 Refrigerant Transition and Recovery Certification exam is a multiple choice, "closed book" proctored format. The candidate seeking certification must score a 70% (18 out of 25 correct) or better on the Core AND on each Type in which he/she is to be certified. A candidate seeking Universal certification must score a 70% or better on EACH of the four sections of the exam.
