TIL about "LOTO" -- "Lock Out Tag Out". This is basically a physical mutex lock -- each worker has their own padlock which they attach to dangerous equipment in order to ensure that it can't be turned on (potentially killing someone) while it's being worked on; once they've completed the high-risk task, they then remove their own lock. Removing or damaging someone else's lock is considered an Extremely Big Deal and liable to get that person fired.
