, Question 1
What is the purpose of the EPA Section 608 certification?
A) To ensure HVAC professionals can sell equipment.
B) To regulate the handling and disposal of refrigerants.
C) To provide training in electrical systems.
D) To certify HVAC technicians in installation techniques.
Correct Option: B) To regulate the handling and disposal of refrigerants.
Rationale: The EPA Section 608 certification mandate aims to ensure that technicians
handling refrigerants understand the proper practices to prevent harmful emissions and
comply with environmental regulations.
Question 2
Which of the following refrigerants is classified as a CFC?
A) R-134a
B) R-22
C) R-410A
D) R-290

systems. CFCs are known for their ozone-depleting properties, which is why their use is
being phased out under the Montreal Protocol.
Question 3
What is the primary goal of the refrigerant recovery process?
A) To recycle refrigerants for profit.
B) To prevent ozone layer depletion.
C) To capture and store refrigerants for reuse or destruction.
D) To monitor refrigerant leaks in systems.
Correct Option: C) To capture and store refrigerants for reuse or destruction.
Rationale: The refrigerant recovery process is designed to safely capture refrigerants
that are not in use or are being removed from systems. This practice is crucial for
minimizing environmental impact and adhering to regulations.
