Final answer:
The most common hazard with conveyors is the risk of entanglement with moving parts, necessitating machine guards and other safety measures to protect workers.
Step-by-step explanation:
The most common machine guarding hazard associated with conveyors is the risk of injury from entanglement with moving parts. Workers can be injured if their fingers, hands, or clothing get caught in the conveyor system. To reduce the risks, machine guards are installed to prevent access to the moving parts. These guards are essential for protecting workers from potential entanglement, impact, or abrasion injuries that can occur at various points along the conveyor, such as at the point of operation, power transmission devices, and other moving parts. Conveyors can also pose other health and safety risks such as the development of musculoskeletal disorders due to repetitive motions or awkward postures when working with or around them. Companies are responsible for implementing engineering controls, work practices, and safety standards to minimize the likelihood of accidents and enhance worker safety.
