- defrost 2y agoIt's been standard in the Australian and Canadian mining industry that long and still today - if several people are working on a machine (crusher, screen, stacker, etc) then they all have seperate keys to seperate padlocks that all lock a "gang plate" that scissors into the main power switch and prevents power on until all padlocks removed and gang plate removed.
