What is the purpose of a shock absorber in a fall arrest system?

The purpose of a shock absorber in a fall arrest system is to reduce the impact of a fall. When a person falls, the sudden stop can generate significant forces on the body and the fall protection system. A shock absorber is designed to extend and dissipate this energy gradually, which minimizes these forces and allows for a safer deceleration of the individual. By absorbing energy and reducing peak loads, the shock absorber helps to prevent injuries that could arise from the abrupt stop associated with a fall.

The mechanism of a shock absorber is critical in ensuring that the forces experienced during a fall do not exceed safe limits, thus enhancing the overall safety of the fall arrest system. This function is paramount in any effective fall protection strategy, as it directly contributes to the health and safety of the worker.
