What are the components of a fall arrest system?

A fall arrest system is designed to safely stop a worker in the event of a fall, and its essential components play a crucial role in ensuring safety during elevated work. The body harness is worn by the worker, distributing the forces experienced during a fall across the body to minimize injury. An anchor point is a secure point of attachment to which the harness and connecting device are attached, ensuring that the system can effectively support the worker's weight and any forces generated during a fall. The lifeline connects the harness to the anchor point, allowing for movement while providing a safeguard in case of a mishap.

In contrast, the other options mention components that either do not contribute specifically to a fall arrest system or are not effective for halting a fall. For instance, safety helmets, fall zones, and safety nets are important aspects of overall fall protection strategies but do not constitute a fall arrest system directly. Similarly, personal protective equipment, warning signs, and barriers serve different purposes in enhancing safety but are not components of a fall arrest system. Lastly, safety harnesses and alert systems do not complete the fall arrest setup without the anchor point and lifeline. Thus, the combination of a body harness, anchor point, and lifeline is the most complete and accurate representation
