EPA 608 609 - EPA Refrigerant Handling Ozone Depletion and Regulations Questions and Answers

Question 1

Which international treaty was established to phase out the production of ozone-depleting substances like CFCs and HCFCs?

Accepted Answer

The Montreal Protocol

Answer

The Montreal Protocol on Substances that Deplete the Ozone Layer is the landmark international agreement designed to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances.

Question 2

Under EPA Section 608 regulations, which of the following refrigerant types has the highest Ozone Depletion Potential (ODP)?

Accepted Answer

CFCs (Chlorofluorocarbons)

Answer

CFCs, containing chlorine, fluorine, and carbon, are the most damaging to the stratospheric ozone layer and therefore have the highest ODP. For reference, CFC-11 has an ODP of 1.0, while HCFCs like R-22 have a much lower ODP (e.g., 0.05), and HFCs and HFOs have an ODP of 0.

Question 3

A technician is servicing a residential split-system air conditioner that uses HCFC-22. According to the Clean Air Act Section 608, what must the technician do with the refrigerant before making a major repair?

Accepted Answer

Recover the refrigerant using EPA-certified recovery equipment.

Answer

Section 608 of the Clean Air Act strictly prohibits the intentional venting of refrigerants. Technicians must use EPA-approved recovery equipment to remove the refrigerant from the appliance before servicing or disposal to prevent its release into the atmosphere.

Question 4

As of 2020, the production and import of new HCFC-22 in the United States have been phased out. How can a technician legally obtain R-22 to service existing equipment?

Accepted Answer

By using refrigerant that has been recovered, recycled, or reclaimed.

Answer

While new production and import of R-22 were banned starting January 1, 2020, its use is still permitted for servicing existing systems. The only legal sources for R-22 are stockpiles produced before the ban or refrigerant that has been properly recovered and then recycled or reclaimed to meet AHRI-700 purity standards.

Question 5

Which of the following is a key requirement under the EPA Section 608 regulations for technicians handling refrigerants?

Accepted Answer

They must pass an EPA-approved certification exam.

Answer

Section 608 of the Clean Air Act mandates that any person who maintains, services, repairs, or disposes of equipment that could release regulated refrigerants into the atmosphere must be certified by passing an EPA-approved examination.
