What type of cut should the rescuer make after the initial hole when cutting the roof with an air chisel?

After making the initial hole in the roof using an air chisel, the rescuer should make a horizontal cut. This approach is vital for effectively creating a larger access point while maintaining control over the roof section being cut. A horizontal cut allows for easier removal of material and helps avoid disturbances to the structural integrity of the surrounding areas. This is particularly important in vehicle rescue situations where precision and safety are paramount.

Making a horizontal cut also facilitates the release of tension on the roof structure, which can prevent debris from falling into the passenger area or onto rescuers and victims. When a horizontal cut is employed, it aligns with the general practices in vehicle rescues that prioritize quick and safe extrication of trapped individuals, allowing rescuers to work more efficiently.

While other types of cuts, such as vertical, diagonal, or circular, may have specific uses in different scenarios, in the context of cutting the roof after an initial access hole, the horizontal cut is the most effective and safe choice.
