Which statement correctly describes guarding removal during belt head maintenance?

• A. Guarding may be removed after the belt is de-energized
• B. Guarding may be removed if a supervisor approves verbally
• C. Guarding may be removed when the maintenance is complete
• D. Guarding may be removed only after power is removed and it has been tagged and locked out from the power source

Answer: (D)

Before any guarding can be removed for belt head maintenance, the equipment must be isolated from its energy source and kept in that state. This means the power is turned off, the energy source is physically blocked or disconnected, and a lock and tag are applied to prevent anyone from re-energizing the belt while work is being done. Only after the system is de-energized and locked out with the tag clearly indicating maintenance in progress should guarding be removed. This approach provides a solid, verifiable safety barrier so the machine cannot start unexpectedly and workers are not exposed to moving parts. Verbal supervisor approval or removing guarding simply because maintenance is finished do not provide the necessary, enforceable protection. The formal lockout/tagout step ensures a consistent, inspectable safety measure that remains in place until it’s safe to restore power and reinstall guards.
