In the same sequence, what step comes after tagging and locking out power?

• A. Test
• B. Ascertain cause
• C. Remove tags and locks
• D. Repair

Answer: (B)

After tagging and locking out the power, the next step is to verify the isolation by testing. This safety check confirms there is no energy present and that the equipment cannot be started while maintenance is performed. You use appropriate test equipment and attempt to operate the controls to ensure no unexpected energizing occurs. If the test shows any energy still present, you re-establish the isolation and retest until a positive halt is confirmed. Only after successful verification do you proceed with the maintenance or repair work. Removing tags and locks comes after the work is completed and the area is safe, and identifying the cause of a fault is part of troubleshooting—not the immediate step right after isolation.
