Question 1
Under Section 608, what is the general rule regarding the venting of refrigerants during servicing, maintaining, or disposing of appliances?
Answer: It is illegal to knowingly vent refrigerants into the atmosphere. Technicians must use approved recovery equipment to capture refrigerants before opening or disposing of any appliance.
Question 2
Which refrigerants are exempt from the Section 608 venting prohibition?
Answer: Nitrogen, R-744 (CO2) used as a refrigerant in certain contexts, and other non-ozone-depleting substances that the EPA has determined do not pose a threat to the environment are exempt from the venting prohibition.
Question 3
What is the 'de minimis' exemption under Section 608 venting rules?
Answer: The de minimis exemption allows releases of refrigerant that are incidental to good-faith recovery efforts, meaning small releases that occur while connecting or disconnecting hoses during proper recovery procedures are not violations.
Question 4
Who is required to be certified under Section 608 regulations?
Answer: Any technician who opens an appliance for maintenance, service, or repair that could release refrigerant into the atmosphere must be certified under Section 608.
Question 5
What are the four types of EPA 608 technician certifications?
Answer: Type I (small appliances), Type II (high-pressure appliances), Type III (low-pressure appliances), and Universal (all types of appliances).
