Before performing repairs on a conveyor system, which safety procedure should be performed?

• A. Notify supervisor
• B. Perform lockout/tag out
• C. Lubricate the drive chain
• D. Run a test with the belt moving

Answer: (B)

Lockout/tagout is the safety step that ensures the conveyor cannot start or release stored energy while someone is working on it. By de-energizing the system, isolating the power source, applying a lock, and tagging the equipment to warn others, you remove the primary risk of sudden movement or energy release. Conveyors can have electrical power, compressed air or hydraulics, and stored mechanical energy in belts, springs, or other components, all of which can injure a worker if the machine is turned on unexpectedly. Verifying zero energy and ensuring all energy sources are secured is what makes it safe to perform repairs.

Notifying a supervisor, while good routine practice, does not physically prevent the machine from energizing. Lubricating parts is a maintenance task that should occur only after the area is confirmed safe, and running the belt while repairs are underway would expose hands, clothing, and tools to moving parts. Lockout/tagout directly addresses the hazard of unexpected startup, which is why it is the correct safety procedure here.
