Which of the following is an example of adequate fall protection during the operation of aerial lift equipment?

A full body harness is considered an example of adequate fall protection during the operation of aerial lift equipment because it is specifically designed to distribute the force of a fall over the body, reducing the risk of injury. When using aerial lifts, the harness should be attached to an appropriate anchorage point within the lift to ensure that the worker is secured and protected from falling.

Using a full body harness provides more comprehensive protection compared to a safety belt, which generally only secures the upper body and may not prevent a fall effectively. Similarly, while rails of a platform lift can offer an additional layer of safety by providing a barrier, they do not provide the same level of personal fall protection that a harness does.

In combination with other safety measures, such as proper usage of the lift and adherence to safety guidelines, a full body harness is an essential component of a safe work environment when working at heights, making it the correct choice in this context.
