What is the first step in the vehicle extrication safety process?

The first step in the vehicle extrication safety process is immobilization. This step is crucial as it ensures that the vehicle remains stationary and does not move during the extrication operation. When a vehicle is involved in a collision, it can be unstable due to damage or the position it has come to rest in. Immobilizing the vehicle helps prevent secondary injuries to both the victims inside the vehicle and the rescuers.

By securing the vehicle, responders can work more safely and effectively, focus on removing the patients with minimal risk, and prepare the scene for further actions like stabilization and power down. Immobilization can include using blocks, chocks, or other devices to ensure that the vehicle does not shift or roll, making it a foundational step before any other extrication techniques or safety measures can be taken.
