Which safety feature protects workers from rotating gears or chains on a crane?

• A. Guards
• B. Shields
• C. Barriers
• D. Covers

Answer: (A)

Guards provide the protective barrier around moving parts to prevent access to rotating gears and chains. By enclosing the dangerous area, they stop hands, clothing, or tools from reaching into the gears while the crane is operating, which directly reduces the risk of entanglement, pinch points, and crush injuries. Shields are typically just plates to deflect objects, barriers are about keeping people out of a zone, and covers may hide the parts or be removable; none of these consistently prevent access in the same way guards do.
