  1. What is the recommended minimum safe approach distance from a burning EV battery fire for untrained personnel?

    Answer: 100 feet

    Fire departments recommend at least 100 feet (30 m) for untrained bystanders due to explosion risk, toxic fumes, and re-ignition potential.

  2. Which toxic gas is produced when lithium-ion battery electrolyte burns or vents during thermal runaway?

    Answer: Hydrogen fluoride (hydrofluoric acid vapor)

    Lithium hexafluorophosphate electrolyte decomposes during thermal runaway to release hydrogen fluoride, an extremely toxic and corrosive gas.

  3. A customer wants to purchase a used Prius Gen 3 (2010-2015) NiMH battery module. What minimum warranty disclosure is considered best practice for AARC members?

    Answer: Remaining capacity test results and as-is condition statement

    AARC best practices require disclosing capacity test results and selling used battery components as-is with documented condition to set buyer expectations.

  4. During EV disassembly, a technician notices the battery pack casing is swollen and deformed. What is the correct immediate response?

    Answer: Isolate the vehicle outdoors, increase monitoring frequency, and contact hazmat if gases detected

    Swelling indicates gas buildup from cell degradation; the pack should be isolated outdoors and monitored for thermal runaway precursors before further handling.

  5. What is the function of the pre-charge circuit found in most EV inverter systems?

    Answer: To gradually charge inverter capacitors before the main contactor closes, preventing inrush current damage

    The pre-charge resistor slowly charges inverter capacitors to battery voltage before the main contactors close, preventing damaging inrush current surges.

  6. Which federal agency's guidelines specifically address emergency response to electric vehicle incidents, including battery fires and extrication?

    Answer: DOT/NHTSA Alternative Fuels Emergency Field Guide

    NHTSA publishes the Alternative Fuels Emergency Field Guide, which gives first responders and recyclers protocols for EV fire, extrication, and HV system handling.

  7. Why is it important for an automotive recycler to record the VIN when processing an EV battery pack for inventory?

    Answer: To enable traceability for recalls, warranty claims, and liability in case of downstream failure

    VIN-linked records allow the recycler to trace any recalled or defective battery pack and respond to liability claims from downstream buyers.
