Is there a charge for "attempted negligent homicide" or something? You did something so catastrophically stupid that was all but guaranteed to kill someone except you got lucky, but you still should end up getting censured so you don't roll the dice on someone's life again
Sometimes this isn't possible if the machine needs to stay up to temp, like with plastic injection molders. In those cases, the operation can usually be stopped by a padlock placed somewhere on the controls. There's usually training about it for everyone involved to make sure they know what's up.
Yeah I came here to say that this is a fucking terrifying "LOTO" (and I'm using the term very loosely here) procedure that most likely will eventually kill someone
If a tool or machine can simply be unplugged, and the worker performing the service remains in control of the plug, then lockout procedures aren’t necessary.
There is always a way to disable a machine. The button has power. At the very least, the power to that button should be locked out. If it has to happen at the breaker, so be it.
Just one padlock is enough, but you can use up to 6.
You need all the locks removed before it'll open, so you don't need to count on someone to carefully count everyone back in. You just make sure that each person uses their own lock
I think it's so you can create "and" conditions for unlocking. IE: If you've got two locks, each with their own key, both person 1 AND person 2 need to unlock it. So you can have multiple people and/or multiple crews working on the machine across different aspects. Maybe one crew is doing electric, the other some kind of plumbing, and they're working at different times. When one crew finishes their work, they can release their lockout without making it unsafe for the other crew.
Had the same thought. The American date format must be the least intuitive, but as a nerd that likes to order files and folders YYYY/MM/DD is just a win.
The real question is whether this was put up on April 2 or is a really old sign from Feb 4. ISO 8601 saves lives people, but probably not as many as proper lock out/tag out procedures.
As long as that sign is there, don't fucking touch it. Go figure out who put it there and ream there ass for writing it instead of locking out the machine.
The airlock pressurizer is keeping them alive. DO NOT PRESS THE AIRLOCK BUTTON UNLESS THEIR SPACESUITS ARE SEALED AND TETHERED. You don't want the maintenance crew shot into outer space!
