Violation of lock out procedures was automatic loss of remainder of the shift plus one day disipline. They were threatening similiar disipline for eye and ear protection violations before I retired.
I'm with you on this, especially:
I've seen that happen.
Working on a 4-story hotel, the GC had a stated policy... no radios. But the Super said he'd allow them as long as it didn't get out of hand, and they disappeared whenever his boss was on site.
I was working on the third floor, listening to someone's radio, and the Super asked if it was mine. I said, "No, I don't know whose it is. It's been here all week, and I've never seen anyone touch it." He said it needs to go away tomorrow as his boss was going to do a walk-though.
Next day, the radio's still there, still playing. The Super comes up to me again and asks, "That's not your radio?" "Nope, not mine." I tell him. So he reaches into my pouch, grabs my side cutters, goes over and unplugs the radio, cuts the cord off, and chucks it out the window into the dumpster. He then calmly replaced my cutters in my pouch and said, "Just wanted to make sure!"
From my perspective not every situation is the same. I've spent weeks working, alone, in switchgear rooms, electric closets or dimmer rooms. A complete ban, which would ban a radio under those conditions, is somewhat ridiculous.
