Tell this to your supervisor. When human hand contacts a live electrical wire, the muscles of the hand contract. This can cause the hand to firmly grip the live wire, and prevent the person from letting go. Sometimes the only thing that can allow the person to survive this event is when the body loses complete control of all muscles, and drops towards the floor. The weight of the falling body might, I say might, be enough to pull the hand away from the live wire. But if there is not enough room for the person to fall to the ground, if for example there is a cabinet that is so deep that it blocks the person’s body from falling away from the control box, then that person will die. That is the reason that I, as a design engineer, rigorously defend the space that is reserved for working clearance.
I don’t think the owner of this forum would mind my adding one more thing. I have sat in a classroom, attending Mike Holt’s Grounding and Bonding seminar, and hearing him say that he survived an electrical shock event in exactly the way I described above. He said that he still recalls repeatedly saying to himself, “Let go, you idiot, or you are going to die.” It was only the fact that he fell away from the live wire that allowed him to survive.
