AARC Recycling Processes & Dismantling Procedures 2

Question 1

When dismantling a hybrid vehicle, what is the FIRST safety step before removing the high-voltage battery?

Accepted Answer

Disconnect the 12V auxiliary battery and wait the manufacturer-specified discharge time

Answer

Disconnecting the 12V auxiliary battery disables the HV system's control circuits, and the wait time allows capacitors to discharge to safe levels.

Question 2

Which component must be removed BEFORE depressurizing a vehicle's air conditioning system during dismantling?

Accepted Answer

Refrigerant must be recovered before any component removal

Answer

EPA Section 608 regulations require refrigerant recovery before any AC system component is removed or opened.

Question 3

What is the proper method for removing a catalytic converter for resale as a recyclable commodity?

Accepted Answer

Remove with at least 6 inches of pipe on each end to preserve converter integrity

Answer

Leaving pipe stubs on each end protects the substrate and makes the converter easier to handle and grade for precious metal recovery.

Question 4

During airbag module removal, a technician notices the squib connector is corroded. What should be done?

Accepted Answer

Tag the vehicle as non-deployable and follow the facility's inoperable airbag disposal protocol

Answer

A corroded squib connector creates uncertainty about deployment status; the unit must be treated as potentially inoperable and disposed of per facility SOP, not resold.

Question 5

In an automotive recycling facility, 'secondary containment' around fluid storage tanks is required to hold at minimum:

Accepted Answer

110% of the largest single tank's capacity

Answer

EPA Spill Prevention, Control, and Countermeasure (SPCC) rules require secondary containment of at least 110% of the largest tank to contain a full spill plus precipitation.
