When dismantling a hybrid vehicle, what is the FIRST safety step before removing the high-voltage battery?
Answer: Disconnect the 12V auxiliary battery and wait the manufacturer-specified discharge time
Disconnecting the 12V auxiliary battery disables the HV system's control circuits, and the wait time allows capacitors to discharge to safe levels.
Which component must be removed BEFORE depressurizing a vehicle's air conditioning system during dismantling?
Answer: Refrigerant must be recovered before any component removal
EPA Section 608 regulations require refrigerant recovery before any AC system component is removed or opened.
What is the proper method for removing a catalytic converter for resale as a recyclable commodity?
Answer: Remove with at least 6 inches of pipe on each end to preserve converter integrity
Leaving pipe stubs on each end protects the substrate and makes the converter easier to handle and grade for precious metal recovery.
During airbag module removal, a technician notices the squib connector is corroded. What should be done?
Answer: Tag the vehicle as non-deployable and follow the facility's inoperable airbag disposal protocol
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.
In an automotive recycling facility, 'secondary containment' around fluid storage tanks is required to hold at minimum:
Answer: 110% of the largest single tank's capacity
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.
Which of the following best describes the correct procedure for removing mercury switches from vehicles built before 2003?
Answer: Remove switches from hoods, trunks, and ABS systems and place in dedicated mercury collection containers
Mercury switches must be removed pre-shredding and collected in sealed containers for proper mercury recycling under state and federal hazardous waste rules.
When processing a vehicle with an intact fuel tank, what is the OSHA-recommended method for removing residual gasoline?
Answer: Use an approved pump or vacuum extraction system into a closed, labeled container
Closed-system pump or vacuum extraction prevents vapor release and ignition risk, complying with OSHA flammable liquid handling standards.
