When working from an aerial lift, what type of system must be used for fall protection?

When working from an aerial lift, a personal fall arrest system must be used for fall protection to ensure the safety of the worker. This system typically includes a full-body harness, a lanyard, and an anchorage point that can absorb the force of a fall and restrain the worker, preventing them from falling to the ground if they slip or lose their balance while working at height.

The personal fall arrest system is specifically designed to minimize the distance and impact of a fall, which is crucial when working in elevated positions like those provided by aerial lifts. It offers the necessary security and compliance with safety regulations that protect workers in situations where a fall could result in serious injuries or fatalities.

Using this system not only adheres to industry regulations but also promotes a safety culture by ensuring that all necessary precautions are taken when operating at heights. The other options either do not provide adequate protection or are not appropriate for use in this context, highlighting the importance of the personal fall arrest system as the correct choice.
