In the context of high-angle rescue, what does the term 'edge protection' refer to?

The term 'edge protection' in high-angle rescue specifically refers to equipment and measures put in place to secure the litter at the cliff's edge. This is a critical component in ensuring the safety and stability of the rescuer and the subject being rescued when dealing with steep or vertical terrains. By securing the litter at the edge, the risk of a fall or slide is significantly reduced, thereby enhancing the overall safety of both the rescuer and the individual being rescued.

While devices that prevent rescuers from falling, protection measures for the subject being rescued, and safety gear for the rescue team are all important considerations in a rescue operation, they do not specifically address the direct need for stabilizing or securing the equipment being used at the edge of a cliff or incline. Edge protection ensures that the area immediately surrounding the edge is handled safely, which is crucial in high-angle scenarios where gravitational forces can pose a severe risk.
