What is step three in USAF lockout and tagout program?

Step three in the USAF lockout/tagout program involves verifying the isolation of the energy sources. This step ensures that all energy sources have been effectively shut off and that the equipment is not capable of being re-energized while maintenance or servicing is taking place. Personnel must check that all locks and tags are in place, and they often perform an additional test to confirm that the equipment is de-energized before beginning work. This step is crucial for ensuring the safety of maintenance workers.
