Which step comes immediately after applying lockout in a lockout/tagout procedure?

• A. Tag Out
• B. Verify De-energization
• C. Perform Service
• D. Restore Energy

Answer: (B)

After locking out the energy source, the next step is to verify that the equipment is truly de-energized. This means confirming there is no electrical energy present and that stored or residual energy (like in capacitors, springs, or pressure systems) cannot cause unexpected movement or energize the equipment again. Use the appropriate testing instruments and attempt to operate the controls in a controlled way to prove the energy is isolated. Only then is it safe to proceed with the service. If the verification shows any energy still present, you must re-isolate and re-check until you get a definite zero-energy condition. Restoring energy comes last, after the maintenance is finished and the area is cleared. Tagging accompanies lockout, but the crucial immediate follow-up step is confirming de-energization.
