EPA 608 609 - EPA Refrigerant Handling Certification EPA 609 Practice Test 1

Question 1

Under EPA Section 609, which of the following actions is explicitly prohibited when servicing automotive air conditioning systems?

Accepted Answer

Venting refrigerant directly into the atmosphere

Answer

EPA Section 609 prohibits the knowing venting of refrigerants used in motor vehicle air conditioning systems into the atmosphere. This applies to all refrigerants including R-12, R-134a, and R-1234yf. Technicians must use approved recovery equipment.

Question 2

Which refrigerant was commonly used in automotive A/C systems manufactured before 1994 and is now tightly regulated due to its ozone-depleting potential?

Accepted Answer

R-12

Answer

R-12 (CFC-12) was the standard automotive A/C refrigerant before 1994. It is a chlorofluorocarbon (CFC) with high ozone-depleting potential and was phased out under the Montreal Protocol. R-134a replaced it in new vehicles starting in 1994.

Question 3

What is the minimum equipment requirement for a technician performing refrigerant recovery on a motor vehicle A/C system under Section 609?

Accepted Answer

A certified recovery machine that meets SAE J2788 or J2810 standards

Answer

EPA Section 609 requires technicians to use refrigerant recovery equipment that meets SAE standards (J2788 for R-134a or J2810 for R-1234yf). Equipment must be certified to ensure proper refrigerant capture rates and prevent atmospheric release.

Question 4

When recovering R-1234yf from a motor vehicle A/C system, technicians must use equipment that is:

Accepted Answer

Dedicated to R-1234yf and not cross-contaminated with other refrigerants

Answer

R-1234yf requires dedicated recovery equipment because mixing it with R-134a or other refrigerants makes reclamation impossible and can create unsafe conditions. Equipment must be clearly labeled and kept separate to maintain refrigerant purity for reuse or reclamation.

Question 5

Under EPA Section 609, which entity is responsible for ensuring that technicians who purchase refrigerant in containers larger than 2 pounds are properly certified?

Accepted Answer

The refrigerant wholesaler or retailer selling the refrigerant

Answer

EPA regulations require refrigerant wholesalers and retailers to sell containers larger than 2 pounds only to certified technicians. The seller bears responsibility for verifying certification before completing the sale, making point-of-sale verification a key enforcement mechanism.
