For what purpose besides holding a load line are prusiks used?

Prusiks are primarily known for their ability to hold a load line, but they also play a significant role in self-rescue situations. When a rescuer or individual finds themselves in a predicament while on a rope system, a prusik knot can be used effectively to create a backup or safety mechanism. By tying a prusik on their own harness, a person can ascend or descend the rope safely, should they need to escape or lower themselves in a controlled manner. This self-rescue capability is crucial in various rope rescue scenarios where maintaining safety while maneuvering along the rope is essential.

The other options, while relevant to the broader context of rope rescue, do not capture the unique and critical function of prusiks in self-rescue. For example, while prusiks can provide some assistance in creating additional loops or securing equipment, they are not specifically designed for those purposes, making the self-rescue function particularly vital in emergency situations.
