OSHA Lockout/Tagout Training

I have had to drive to guy's houses before to drag them in to take their lock off.

Not so much safety, but it really used to piss me off, we'd have to go up to some radio site, with a "big chain" of padlocks at the gate chain, and usually, the gate is already way up some goat - trail of a road/ hill/ mountain, and there you are ---"your" padlock is locked out of the chain.

I've never understood what is so dammed complicated about putting a lock in a chain so everybody is "in"
