What safety equipment is commonly used by ironworkers when working at heights?

Harnesses, lanyards, and personal fall arrest systems are essential safety equipment for ironworkers who are frequently required to work at heights. This equipment is specifically designed to prevent falls and protect workers from potential injuries that can occur if they slip or lose their footing while working on elevated structures.

A harness is worn around the body and can be connected to a lanyard, which in turn can be secured to an anchor point or safety line, creating a reliable fall protection system. Personal fall arrest systems are crucial as they not only stop a worker from falling but also assist in safely lowering them if they do experience a fall.

While hard hats and gloves provide essential head and hand protection, they do not specifically address the risks associated with working at heights as directly as harnesses and fall arrest systems do. Hearing protection and goggles help protect against noise and flying debris but do not mitigate the risk of falling. Shirring is not a recognized term in the context of safety equipment for construction work. Thus, the chosen answer reflects the best practice for ensuring safety when working overhead.
