AARC - Accredited Automotive Recycler Vehicle Dismantling Procedures Questions and Answers

Question 1

During the vehicle depollution process, which of the following components must be removed or deployed before the vehicle is crushed to prevent potential explosions and ensure worker safety?

Accepted Answer

Airbags and seatbelt pretensioners

Answer

Airbags and seatbelt pretensioners contain explosive charges that must be safely deployed or removed before a vehicle undergoes crushing. This is a critical safety step to prevent accidental detonation, which can cause serious injury and damage equipment. While other components listed are removed, they do not pose an explosive risk.

Question 2

A technician is dismantling an end-of-life hybrid vehicle. They correctly identify the high-voltage battery as a Nickel-Metal Hydride (NiMH) type. What is the most critical first step the technician must take before attempting to remove the high-voltage battery pack?

Accepted Answer

Ensure the high-voltage system is properly de-energized and verified.

Answer

High-voltage systems in hybrid and electric vehicles, typically ranging from 400 to 800 volts, pose a significant risk of fatal electric shock. Before any physical work begins on the high-voltage battery, the system must be safely disconnected and verified as de-energized using proper procedures and equipment to ensure technician safety.

Question 3

Which of the following is considered a best practice for managing fluids drained from a vehicle during the dismantling process to prevent environmental contamination?

Accepted Answer

Storing different fluids in separate, clearly labeled, and sealed containers.

Answer

To prevent cross-contamination and ensure proper recycling or disposal, best practices and regulations require that different fluids (e.g., oil, antifreeze, brake fluid) be drained and stored in separate, labeled, and sealed containers. This allows each fluid type to be managed appropriately, protecting the environment and maximizing recycling potential.

Question 4

When handling an undeployed airbag module that has been removed from a vehicle, what is the correct safety procedure?

Accepted Answer

Always carry the module with the trim cover facing away from your body.

Answer

Undeployed airbags pose a significant safety risk. The correct procedure is to always carry the module with the trim cover (the side the airbag deploys from) facing away from your body. This directs the force of an accidental deployment away from the handler, minimizing the risk of serious injury.

Question 5

A recycling facility receives an end-of-life electric vehicle (EV) with a damaged lithium-ion battery pack. According to safety protocols, what action should be avoided when moving this vehicle within the yard?

Accepted Answer

Using a forklift or skid steer to lift the vehicle from underneath.

Answer

EV battery packs are typically located on the underside of the vehicle. Using equipment like a skid steer or forklift to lift from underneath can easily puncture or further damage the battery pack, leading to a dangerous thermal runaway event (fire or explosion). Extreme caution must be used, and lifting from designated frame points is required.
