Which statement about LOTO implementation is true?

• A. Notification is optional if workers are trained
• B. Only site supervisors can implement LOTO
• C. Affected employees must be notified prior to and during implementation
• D. LOTO requires only written notices

Answer: (C)

Lockout/Tagout hinges on making sure workers who could be exposed to hazardous energy know what’s happening when equipment is isolated. Before energy is cut off, affected employees must be informed that a shutdown is starting and why, and they should stay informed throughout the energy-control process. This communication prevents anyone from being surprised by a re-energized machine and helps ensure safe operation while maintenance or repair is underway.

That’s why the statement about notifying affected employees prior to and during implementation is the correct one. Training matters, but it doesn’t replace active notification. LOTO is carried out by those authorized to perform the control, not only by site supervisors. And while written energy-control procedures are essential, they don’t substitute for real-time communication with workers about the lockout/tagout activity.
