What three items are essential to a fall arrest system?

A fall arrest system is designed to protect individuals from falls when working at heights by stopping them in a controlled manner. The three essential components of a fall arrest system are a full body harness, a lanyard, and an attachment point.

The full body harness is vital because it distributes the forces of a fall across the body, minimizing the risk of injury. It is specifically designed to keep the worker upright in a fall situation, preventing them from flipping upside down or being thrown out of the harness.

The lanyard connects the harness to the attachment point, and it can include features such as shock absorption to reduce the forces experienced in the event of a fall. The attachment point is the secure anchor that connects the system to a stable structure, vital for ensuring that the fall arrester can safely stop a fall.

The other options do not include this combination of components or include items that do not meet the safety standards for fall protection. For instance, safety belts, which were once common, are no longer recommended due to the lack of full body support, leading to potential injury in the event of a fall. Understanding the accurate composition of a fall arrest system is crucial for ensuring safety and compliance with regulations.
