A fall arrest system is a type of fall protection system that is designed to stop a worker after a fall has already occurred. The system includes an anchor point or several anchor points, a harness for each worker, and a self-retracting lifeline or safety lanyard connecting the harness to the anchor point. Fall arrest systems are engineered to withstand the much greater forces associated with stopping falls and must stop a fall before an employee strikes surfaces below the work area. The equipment is also designed to account for the forces that accumulate in stopping such a fall using shock absorbers, which prevent the user from sustaining serious bodily injuries. Fall arrest systems are ideal for jobs where workers need to complete tasks in a wide area, right up to the edge of a raised platform, and workers would need full freedom to move around these areas and reach those places on or near the edge, which puts them at a greater risk of falling.
