Which of the following is not a component of a worker's fall protection system?

The correct answer is that a safety helmet is not a component of a worker's fall protection system. Fall protection systems are designed specifically to prevent falls from heights and ensure that if a fall does occur, the worker is adequately protected.

A body harness is a crucial element that distributes the force of a fall across the body and connects the worker to the fall protection system. Lanyards are also an essential part, as they connect the harness to a secure anchor point, allowing for movement while ensuring safety. Deceleration devices, such as shock absorbers or self-retracting lifelines, are designed to slow down the fall and reduce the impact forces experienced by the worker during a fall.

While a safety helmet provides important head protection, it does not directly prevent falls or mitigate their effects in the same way that the other components do. Thus, while it is an important aspect of workplace safety gear, it isn't classified as part of the fall protection system itself.
