What is the purpose of using cribbing during a rescue?

The purpose of using cribbing during a rescue is to provide additional support and prevent the vehicle from shifting. Cribbing consists of wooden or composite blocks that are strategically placed to stabilize a vehicle or object that may be compromised. When a vehicle is involved in an accident, it can be unstable, posing risks not only to the rescuers but also to the victims inside. By using cribbing to support the vehicle, rescue teams can ensure that it remains stationary while they work, reducing the risk of further injury or additional accidents during the extrication process. This technique is critical for maintaining a safe working environment, allowing rescuers to focus on their tasks without the constant concern of the vehicle shifting unexpectedly.

The other options, while they may touch on safety or aiding in the rescue, do not directly address the primary function of cribbing. Cribbing is specifically designed for stabilization rather than creating barriers, securing medical equipment, or assisting in the lifting of tools. Each of those functions is important in a rescue operation, but they do not capture the central purpose of cribbing.
