For both work at height and rescue, access from above is preferable because it allows one to take advantage of the force of gravity. Descenders are designed to regulate friction and control the descent on a fixed rope. They allow a worker to position himself at any point on the rope. Some descenders can also be used to safely belay a leader using rock climbing techniques.
