AARC Vehicle Dismantling Procedures 5

Question 1

What is the correct method for handling a vehicle with an unknown or mixed refrigerant before A/C system recovery?

Accepted Answer

Use a refrigerant identifier to determine the type before selecting recovery equipment

Answer

Mixed or contaminated refrigerant can damage recovery equipment and must be identified with a refrigerant analyzer before recovery to select proper equipment and handling procedures.

Question 2

Under the Clean Air Act, what is the minimum size of an A/C system that requires certified refrigerant recovery before disposal?

Accepted Answer

All motor vehicle A/C systems regardless of refrigerant quantity

Answer

EPA Section 608 regulations require recovery from all MVAC systems regardless of refrigerant quantity—there is no de minimis exemption for vehicle A/C systems.

Question 3

What is the term for the process of accelerating fluid drainage by puncturing the transmission pan or differential cover with a specialized drill tool?

Accepted Answer

Puncture draining or drill-and-drain method

Answer

The drill-and-drain (puncture drain) method uses a specialized bit to pierce the pan and quickly drain fluids into a capture system, reducing depollution cycle time.

Question 4

A technician is removing a front subframe. Which factor most directly determines whether it can be resold as a used part versus scrapped?

Accepted Answer

Structural integrity—absence of cracks, bends, or corrosion-compromised mounting points

Answer

Subframes are safety-critical structural components; only units free of cracks, deformation, and severe corrosion at mounting points can be certified for resale.

Question 5

Which of the following best describes 'vehicle inventory management' in an AARC-compliant operation?

Accepted Answer

Tracking each vehicle from acquisition through depollution, parts harvest, and final disposition using a documented system

Answer

AARC-compliant inventory management requires documented tracking of each vehicle through every stage—acquisition, depollution, dismantling, parts cataloging, and final disposition.
