Before executing a cut, what must a rescuer ensure regarding the blade?

Ensuring that the blade is perpendicular to the target object before executing a cut is crucial for effective and efficient cutting. When the blade is positioned perpendicularly, it maximizes the cutting surface area in contact with the material, allowing for a more controlled and precise cut. This positioning also helps to minimize the risk of the blade slipping or becoming misaligned, which could result in an ineffective cut or damage to the equipment.

While the sharpness of the blade, its length, and whether it is manually operated are important factors in the overall cutting process, they do not directly address the immediate requirement for stability and accuracy during the execution of the cut. Focusing on the angle of the blade ensures the cut is performed effectively, enhancing the safety and success of the rescue operation.
