Which tool is primarily used for stabilization when a vehicle is on its side?

The primary tool used for stabilization when a vehicle is on its side is cribbing. Cribbing consists of wooden or plastic blocks that can be stacked in a way that creates a stable base under a vehicle, preventing it from rolling or shifting. This is critical during rescue operations, as unstable vehicles pose significant risks both to the victims inside and to the rescuers.

Using cribbing allows firefighters to ensure that the vehicle's position is secure before attempting to extricate any trapped individuals. Properly placed cribbing can absorb the weight of the vehicle while maintaining stability in various positions, which is essential for safe operations.

In contrast, hose tape, block and tackle, and rescue lift airbags serve different specific purposes. Hose tape is primarily used for securing hoses and is not suitable for stabilization. Block and tackle systems are intended for lifting loads rather than stabilizing them. Rescue lift airbags can elevate vehicles, but they are typically used in conjunction with other stabilization methods, rather than being the primary means of stabilizing a vehicle on its side. Therefore, cribbing is the most effective and widely accepted method for ensuring stability during such rescue situations.
