Which tool is primarily used for lifting debris during rescue operations?

The primary tool used for lifting debris during rescue operations is the air bag. Air bags are specifically designed for situations where lifting heavy objects or debris is required, making them particularly effective in rescue scenarios such as collapsed structures or other emergency situations where movement of debris is critical for the safety of trapped individuals. The air bags can be deployed quickly and inflated to provide significant lifting capacity, allowing rescuers to gently raise heavy materials without causing additional harm to victims or further destabilizing the environment.

While other tools like a jack can be useful in lifting or stabilizing objects, their application is often more mechanical and suited for heavier, larger objects rather than the nuanced needs of rescuing individuals trapped under debris. The hand saw, primarily a cutting tool, and prying tools, which are utilized more for leverage and movement rather than lifting, do not possess the specific functionality required for lifting debris effectively in the context of rescue operations. Thus, the air bag is the most appropriate and specialized choice for this particular task.
