Scada systems make it so that the work performer doesn’t have a physical lock on the system. Systems can be remotely energized if someone fails to follow standard practices, safeguards ect.Not to sidetrack things, but in my lock out/tag out training, Jamil would have to have his lock/tag on the equipment and verify it is in safe condition himself. You can lock it out too, but as the person working on the equipment he “must“ have his on it.
