AARC Vehicle Dismantling Procedures 4 â Questions and Answers
Question 1: In the context of automotive recycling, what is 'parts harvesting' and when is it prioritized over whole-car crushing?
- Harvesting is always performed regardless of vehicle condition
- Harvesting is prioritized when part resale value exceeds the scrap metal value of the vehicle (Correct answer)
- Harvesting only applies to luxury vehicles
- Harvesting is done after crushing to sort metal types
Correct answer: Harvesting is prioritized when part resale value exceeds the scrap metal value of the vehicle
Parts harvesting is economically justified when individual component resale value collectively exceeds the vehicle's scrap weight value.
Question 2: What is the purpose of a 'vehicle depollution' step in the ARC-certified recycling process?
- To repaint the vehicle for resale
- To systematically remove all hazardous fluids and materials before dismantling or shredding (Correct answer)
- To inspect the vehicle for stolen parts
- To run a diagnostic scan of all modules
Correct answer: To systematically remove all hazardous fluids and materials before dismantling or shredding
Depollution is the systematic removal of all hazardous materialsâfluids, batteries, airbags, mercury switchesâbefore the vehicle enters the dismantling or shredding stream.
Question 3: When removing a lithium-ion battery pack from an electric vehicle, what is the minimum recommended PPE beyond standard shop gear?
- Only standard mechanic gloves
- Class 0 (1,000V rated) insulating rubber gloves and face shield (Correct answer)
- Chemical splash goggles only
- Leather welding gloves and hearing protection
Correct answer: Class 0 (1,000V rated) insulating rubber gloves and face shield
EV battery packs can carry 400â800+ volts and require Class 0 minimum insulating rubber gloves rated for at least 1,000V to prevent electrocution.
Question 4: Which document must accompany a used airbag module sold to another party to comply with NHTSA and AARC guidelines?
- Original vehicle window sticker
- Vehicle identification number (VIN) record and airbag serviceability documentation (Correct answer)
- State inspection certificate
- Emission test report
Correct answer: Vehicle identification number (VIN) record and airbag serviceability documentation
NHTSA and AARC guidelines require VIN traceability and serviceability documentation for used airbag modules to ensure proper fitment and safety accountability.
Question 5: A recycler is removing an engine from a vehicle with an active fuel rail still pressurized. What is the correct first step?
- Begin loosening fuel line fittings slowly
- Relieve fuel system pressure using the Schrader valve or by removing the fuel pump fuse and cranking (Correct answer)
- Remove the fuel tank before touching the engine
- Disconnect the battery and wait 30 minutes
Correct answer: Relieve fuel system pressure using the Schrader valve or by removing the fuel pump fuse and cranking
Fuel rail pressure (40â80 psi on most vehicles) must be relieved via the Schrader valve or pump fuse-crank method before disconnecting any fuel lines to prevent fuel spray fire hazards.
Question 6: What is the significance of the ARC (Automotive Recyclers Association Certification) program for a dismantling facility?
- It certifies the facility to sell vehicles at auction
- It demonstrates compliance with environmental, safety, and business practice standards for professional auto recycling (Correct answer)
- It provides tax-exempt status for scrap metal sales
- It replaces the need for state environmental permits
Correct answer: It demonstrates compliance with environmental, safety, and business practice standards for professional auto recycling
ARC certification verifies that a recycling facility meets ARA's professional standards for environmental compliance, safe operations, and ethical business practices.
Question 7: When stripping a vehicle for parts in a multi-story storage rack system, what is the most critical safety practice?
- Work from the bottom vehicle upward to reduce walking distance
- Ensure vehicles are properly secured with approved restraints before any work begins under or around stacked vehicles (Correct answer)
- Remove all four tires before stacking to reduce weight
- Always use air tools to speed the process
Correct answer: Ensure vehicles are properly secured with approved restraints before any work begins under or around stacked vehicles
Stacked vehicles must be secured with proper restraints rated for the weight load to prevent catastrophic collapse, which is a leading cause of serious injury in recycling yards.
