Which safety equipment is described as allowing for fall protection while working at heights?

The correct choice relates to a type of safety equipment specifically designed to protect individuals working at elevations. A body belt is a crucial piece of fall protection equipment, as it is designed to secure a worker in place, preventing falls when working at heights. Body belts often have attachment points for lanyards or other fall protection systems, providing an essential safety measure in construction or maintenance scenarios where there is a risk of falling.

The other items listed do serve important safety functions but do not specifically address fall protection. A hard hat protects the head from falling objects and impacts, a face shield protects the face from debris or splashes, and work gloves protect the hands from cuts and abrasions. While all these items contribute to overall safety in the workplace, they do not provide the specific fall protection necessary when working at heights, making the body belt the most appropriate answer for this question.
