What are the required steps in a lockout/tagout (LOTO) procedure for electrical systems on an AMT-2 task?

• A. Identify energy sources, isolate, lockout, verify zero energy, tag, document, release per procedure after task completion.
• B. Identify energy sources, isolate, lockout, tag, verify zero energy, document, release per procedure after task completion.
• C. Isolate, lockout, tag, identify energy sources, verify zero energy, document, release.
• D. Identify energy sources, tag, isolate, lockout, verify zero energy, document, release.

Answer: (B)

The main idea here is the proper sequence of a lockout/tagout procedure for electrical work, making sure energy is identified, controlled, and verified before anyone begins tasks. First, you identify all energy sources that could feed the equipment. Then you isolate those sources so the equipment cannot be energized. After isolation, you apply the lockout device to physically prevent re-energizing. Next, you attach the tag to communicate that the lockout is in place and who is responsible. Only after the lockout and tagging are in place do you verify zero energy, using the appropriate tests to confirm there is no electrical, stored, or residual energy. Documentation follows to record that the LOTO was completed, and release is done only after the work is finished and it’s safe to remove the devices per procedure. Why this order fits best: locking out first creates a tangible barrier that prevents accidental re-energizing, tagging communicates the hazard and accountability, and verifying zero energy confirms it’s safe to proceed. If you verify energy before tagging, or tag before isolating and locking, you’d be relying on a state that could be altered before work starts, which compromises safety.
