What is NOT used as a self-rescue knot?

The Prusik hitch is primarily used for climbing and securing oneself to a rope rather than for self-rescue. It functions by gripping the rope when weight is applied, making it useful in ascent or belaying a climber. However, it is not classified as a self-rescue knot.

In contrast, the figure-eight knot, bowline knot, and clove hitch are all recognized for their applications in self-rescue situations. The figure-eight knot is often used to create a secured loop at the end of a climbing rope, the bowline knot forms a fixed loop that can be easily untied after being under load, and the clove hitch allows for quick securing of the rope to a fixed point. These attributes make them suitable for self-rescue scenarios, unlike the Prusik hitch, which doesn't facilitate the same type of release or adjustment needed in emergencies.
