you caught the sneaking one - oily galley vents were trouble and something many people forget. "Fat Eddie" our cook striker was always flaring up a well burnt steak on the grill. So we always had a fire extinguisher near him. And "Scrotum Doyle" was grease from head to toe so his clothes and fart sack could ignite with almost any flame (Scrotum was a MM, so don't ask). So you got a lot of the good ones Mark. If Darrin hasn't moved you to the head of the class I will.
When we loaded for stores for a long patrol (nothing like in WWII), we had provisions stuffed, stacked and crammed ever where. Torpedo Rooms were a great place for crates of food. We also seemed to be the place to store ice cream cones. They fit well up on the cable and pipe runs. Besides tripping and walking hazards all of these stores created problems of fire hazards.
Now what abut Maneuvering Room, or the sonar and radio rooms? And one big one - that storage area under the galley for stores. Each place meant fighting a potential fire in a very confined space and possibly having to fight a fire from above it.
Museum boats most likely have many of these hazards, but also consider that you probably store paint and paint thinner in tucked away places. So be aware of what you have stored, where it is stored and have the proper extinguisher on hand.
