Which action is the first step in a Lockout/Tagout (LOTO) procedure?

• A. Notify affected workers.
• B. Apply lockout devices and/or tags.
• C. Verify zero energy.
• D. Re-energize after clearance.

Answer: (A)

Notifying affected workers is the first step because it starts the safety communication that makes everyone aware a lockout is about to be performed. This heads-up prevents coworkers from attempting to use or energize equipment while maintenance is planned, which could create a dangerous situation if someone else re-energizes the machine unexpectedly. Once people are informed, the typical sequence follows: shut down the equipment, isolate all energy sources, apply lockout or tagout devices, verify that all energy has been released and is zero, perform the needed work, and finally remove the devices and re-energize after clearance. Keeping others in the loop at the outset helps ensure a coordinated and safe procedure.
