What is required when handling vehicles that are resting on their side?

When handling vehicles that are resting on their side, stabilization is paramount to ensure the safety of both the rescue personnel and any passengers trapped inside. Using buttress struts is an effective method of stabilization as they provide a secure support structure that prevents the vehicle from rolling further or falling during the rescue operation. This is critical because a vehicle in this position can be precariously balanced, and any movement can lead to additional injuries to those inside or to rescuers attempting to assist.

Stabilization before attempting any other rescue operations is a key principle in vehicle rescue. It allows rescue crews to work in a more controlled environment and minimizes the risks associated with the level of uncertainty surrounding the vehicle's position. The use of buttress struts specifically addresses the unique challenges presented by a vehicle on its side, as they can be adjusted to provide support in various orientations.

Other options, such as complete evacuation of passengers or manual lifting of the vehicle, are not ideal or safe practices without first achieving stabilization. Continuing operations without stabilization poses significant risks, as it can lead to a loss of control over the vehicle's movements. Thus, employing buttress struts is the best method to ensure safe and effective rescue operations.
