Way back when I ran a Marine Electrical Company, the First Question I would ask is what really happened and what we you doing when the problem happened. I never threw anyone under the bus when they told me that maybe they were washing down just before to switchboard blew up. But if I spent several hours searching for a problem before finding that someone had poured water on a live switchboard I would be pissed and let the CE know. Usually this would only happen once and just about all of the crews knew that I was there to help not hurt them.
I also had this posted in my ER Control Booth. I swear one of the AE’s that I had used every excuse known to man rather than just manning up and admitting that he screwed up.
