This accident was caused by a faiure of a worn component in a safety lock-out. Every other "Accident" was caused by someone's carelessness.
Hmmm... Only to be argumentative.

It seems that that incident could be construed as a failure to maintain safety due carelessness or neglect.
The point of the issue at hand: The BOD is acting subjectively and arbitrarily.
