How does a rescuer determine if a situation requires a high angle or low angle evacuation?

Determining whether a rescue situation requires a high angle or low angle evacuation primarily hinges on the type of terrain and slope involved. In rescue operations, the terrain plays a crucial role, as it influences the safety and feasibility of the evacuation method. High angle evacuations are typically necessary in steep, vertical, or overhanging locations where the risks of falling are significant and specialized techniques are needed to safely retrieve a victim. Conversely, low angle evacuations are suitable for gentler slopes where traditional climbing equipment may not be required, and the rescue can be performed more easily with less complex gear.

While factors such as weather conditions, available gear, and the victim's physical condition are important considerations in the overall rescue strategy, they do not directly determine the specific type of angle for the evacuation. Weather conditions could affect safety and choice of gear but do not change the fundamental nature of the terrain itself. Evaluating the rescue gear available can inform the rescuer about capabilities but does not dictate the angle required based on environmental factors. Lastly, understanding the victim's physical condition is vital, but it is the slope of the terrain that fundamentally decides the appropriate evacuation method in terms of angle. Thus, the terrain and slope are the most critical elements that guide this determination in a
