Fire at Sea
I worked on a fish processing ship for a short time. Every week or so we would have a fire drill. The alarm would go off and the captain would come on the P.A. telling us that it was a drill. We would all make our way to the meeting point midships and basically act accordingly.
One night the alarm went off but no announcement was made. Me and like three other crew members immediately got up and headed for the meeting spot. A supervisor mentioned that it was probably just a glitch and not to worry about it.
It took a full five minutes with the alarm going off till everyone finally made it to the meeting point. As it was, I was standing at the survival suit locker at the ready to start handing them out. This was the deck supervisors job, but he was one of the last to get there.
What blew my mind was that there actually was a small easily controllable fire happening in the engine room right then. If I had been the captain, heads would have rolled. Story credit: Reddit / Digipete
