The operator should never be in harms way period. If they are working on equipment it should be physically locked out, say a valve would have a 6" diameter pin through the mechanism and a padlock on it so the pin can't be removed except by the operator, and electrical equipment is powered off and the breaker is locked in the off position. If they put themselves in harms way they will eventually be fired for unsafe work.
bad updates are bad updates. they are incompetence on the part of the programmer. but the worst they should be able to cause is minor equipment malfunction or the physical system has been poorly designed.
