One time we were on this job during a plant shutdown. everyone on our crew attached a lock to the LOTO slot. One guy took off without undoing his lock. Everyone had to wait for this guy to answer his phone, turn around, drive back, get his PPE back on, walk back to the lock box and cut his own lock.

There was nobody inside the facility, every machine was shut down for the day. Still, not a single one of these incredibly impatient and pissed off tradesmen even JOKED about cutting buddy's lock. You just don't do it
