How must guards at conveyor drive, head & tail pulleys be built?

• A. Sufficient enough to prevent a person from reaching behind the guard
• B. Decorative and lightweight
• C. Easily removable
• D. Transparent

Answer: (A)

Guarding around conveyor drive, head, and tail pulleys must block access to moving parts. The best design is sturdy and enclosure-like, so a person cannot reach behind the guard to touch the belt, pulley, or nip points. This prevents entanglement and injuries by removing any feasible route to contact the moving parts. Guards that are decorative, lightweight, easily removable, or merely transparent fail to provide real protection because they can be bypassed, damaged, or removed, exposing the hazard. The essential requirement is a guard built strong enough to prevent a person from reaching behind it.
