possible to eliminate the risk of falling, a system must be adopted that minimizes the size and consequences of a fall. The fall arrest system consists of a parachute harness (mandatory), a fall arrest safety lanyard or a fall arrester and an anchoring device. The system must have a means of absorbing energy to limit the forces generated on the worker and also protect the anchoring.
