CAR Vehicle Dismantling & Processing 2

Question 1

When dismantling a hybrid vehicle, which component must be de-energized FIRST before any other work begins?

Accepted Answer

High-voltage battery pack

Answer

The high-voltage battery pack must be de-energized first to eliminate electrocution risk before any hybrid vehicle dismantling proceeds.

Question 2

Which EPA regulation specifically governs the handling and disposal of automotive mercury switches during vehicle dismantling?

Accepted Answer

End-of-Life Vehicle Solutions (ELVS) program standards

Answer

The ELVS program sets voluntary but widely adopted standards for recovering mercury switches from end-of-life vehicles before crushing.

Question 3

A vehicle arrives with an undeployed side-curtain airbag. What is the correct handling procedure before dismantling the door panel?

Accepted Answer

Deploy the airbag using a deployment tool before removal

Answer

Undeployed airbags should be deployed using a proper deployment tool before dismantling to prevent accidental activation that could injure workers.

Question 4

When draining engine oil from a vehicle, what is the minimum temperature consideration for efficient drainage?

Accepted Answer

Warmer oil drains faster and more completely than cold oil

Answer

Warmer oil has lower viscosity and flows more freely, resulting in faster and more complete drainage, which maximizes recovered oil volume.

Question 5

Which of the following best describes 'depollution' in the context of automotive recycling?

Accepted Answer

Extracting all hazardous fluids and materials before processing

Answer

Depollution refers to the systematic removal of all hazardous materials including fluids, batteries, and mercury switches before a vehicle is shredded or processed.
