Name one example of a mechanical hazard that requires guarding.

Entanglement is a specific type of mechanical hazard that can occur when a person becomes caught in moving machinery or equipment, leading to serious injuries or even fatalities. This hazard often arises in machinery with rotating parts, belts, chains, or similar mechanisms that can inadvertently grab clothing, hair, or body parts. Proper guarding can prevent access to these moving parts, effectively minimizing the risk of entanglement. By installing physical guards such as protective barriers or covers, employers can protect workers from the dangers posed by this hazard.

While noise pollution, image interference, and electrical hazards are certainly important safety concerns in various contexts, they do not fall under the category of mechanical hazards that require guarding in the same way entanglement does. Noise pollution pertains to auditory disturbances, image interference relates to visual clarity issues, and electrical hazards involve risks associated with electrical systems. None of these directly involve mechanical components where guarding is specifically necessary to protect workers from injury due to machine operation.
