I worked in a large computer lab back in the late 90s
Right next to the door was a Big Red Button that said “emergency power cutoff” and yes I wanted to push it.
one day I walked in and there was an electrician messing with the Button, I asked him what was going on and he said
“it was determined that there is .0004% chance that if you hit the button the power will not shut off, so after consultation with the corporate Attys we have decided to remove the button since we could get sued if you pushed it and it did not work”
I still have that Big Red Button.
I worked in a place that had a Big Red Button by the door.
Someone leaned on it once by accident.
It worked.
After that they installed a safety cover over it.
