Old thread but this deserves a mention.
ALWAYS. OBEY. LOCKOUT. TAGOUT.
My dad had to literally save a mans life because of improper lockout tagout when the electrician at the factory thought power was off in a crawl space and began arcing with >40KV electricity shooting through him. My dad found the breaker, turned the power off, pulled his charred body out and began CPR while screaming at others to call 911. He broke a bunch of the mans ribs giving CPR, but the man survived. When the guy woke up in the hospital he just kept repeating, "You saved my life, Mike. You saved my life, Mike!"
There's no excuse to not leave a simple lockout when you "hack" something into being counter-intuitive. Being lazy doesn't just cost dollars, it costs lives. You don't want to be responsible for someone's death, and you don't want to be on the receiving end of it either.
