    That is a really Rube Goldberg-ian way of making sure equipment isn't run when somone is inside...

    It may well be Bruce, but I've witnessed an idiot supervisor remove an electricians lock out from a switchgear because he wanted to look good and have all of his machines running when his boss walked through. Never mind the reason for the lockout to be on the switchgear in the first place.
    Never try to tell me it can't be done

    Yikes! I take it back...it needs more keys, a little curvy slide with a steel ball and cage falling down a tall toothed pole at the end.

    With the supervisor standing in for the little plastic mouse, of course.

    Way back, I worked in safety consulting. Too many companies ignored proper lockout. Two accident investigations stand out in my memory. In the first, a young guy lost two hands in an instant setting up a metal press. In the second, two guys literally lost their heads in a crane accident

    The other striking thing I learned during that time. If you ever read the preamble and correspondence behind OSHA rules, you'll find typically one of two reasons a certain rule was created: The first is because a number of people have died. The second, is a company might have an edge versus other companies, or have a monopoly on selling required goods or services if certain rules were implemented

    Use to commonly see A/B lockout keys used on dual electric feeds to a single location. What hard is an A/B/C system with no labeling. Had to reverse engineer one of those!

    One of my friends was the first Police officer, thus became the coroners 'officer', on the scene of a decap. The store manager had removed the interlocks and modified the limit switches so a 'lift-plate' scissor lift cycled continuously between the floors of a frozen food retail store. One of the Saturday lads slipped/tripped and got caught between the end of the lift and the floor, it tore his head off. He suffered PTSD and ended up unemployed, the black & white evidential photo's were bad enough.

    Lockout and safety systems are too easily abused by 'get it done' & 'efficiency' idiots, in the power industry where big machinery, high pressure superheated steam and high voltage were the usual risks no-one on the staff dared to interfere. The refit contractors who did got beaten, like the one who almost killed me inside a boiler front by bypassing all the locked out CDA (connected a Nitrogen cylinder) and activating the burner carrier we'd just climbed across, our 3rd man on the outside beat him senseless, then broke his hands so he'd remember not to ever do it again...
