Are both high angle and low angle evacuations considered "technical rescue"? Why?

Both high angle and low angle evacuations are considered "technical rescue" because they necessitate the use of rope rescue techniques that require specialized knowledge and skill. Technical rescue encompasses operations where rescuers must navigate challenging or dangerous environments, utilizing equipment such as ropes, harnesses, carabiners, and other hardware to safely access and extricate individuals in distress.

High angle rescues, typically involving steep or vertical terrain, and low angle rescues, which may be performed on slopes, both demand an understanding of mechanical advantages, systems safety, and the dynamics of working with ropes. Rescuers must be trained in these techniques to ensure effective and safe rescues to minimize further risk to both the victim and the rescue personnel.

The other options do not capture the full scope of what defines technical rescue. While both types of evacuation indeed require training, it’s the specific application of rope rescue techniques that solidly classifies them under the umbrella of technical rescue.
