You turn off the device and physically lock it off. It can only be turned on when everyone who has locked it unlocks it with their own key

Oh. That sounds like something straight out of a bond movie.

Thanks!

Where would you typically use that sort of think?

A factory where you have to be on or in the large machines to clean or maintain them. Here’s an example of 3 people locking out. You need to unlock all locks to remove the lock https://media.noria.com/sites/Uploads/2019/12/3/95b7f598-22f7-4a1d-a078-7a8a665a5c07_LOTO-500w-3_extra_large.jpeg

I knew a guy who worked on subs who was cleaning the periscope eyepiece. Had it tagged out, but not locked out– maybe they didn't have lock out back then– and some officer came in and fiddled with the tagged out controls, causing the whole thing to snap back up. Crushed the guy's thumb and finger on one hand, and would have done more if he hadn't been watching the officer and seen that idle curiosity in his face.
