I used to work in the US Navy, part of my job and responsibilities was structural, shipboard and flight deck firefighting, and eventually I got certified as an assistant Fire Marshall, and I also worked with shipboard firefighting simulators. Not programs, building actual fires on old ships. One of the biggest fears on a vessel is an engine room fire. Your talking about a class Bravo fire in a 3 story enclosed space, filled with fuel, and lube oil pumps, storage containers filled with anything from oily rags, oil cans, paint cans, as well as installed pipping filled with different grades and qualities of lubricating oil and jet fuel and then filled with black smoke so thick you cant see without a thermal scanner. In copies of Engine room reports they indicate fires can get anywhere from 1200-1600 K or 1700-2420 F. But tests and actual shipboard fires have gotten as hot as ~ 2000K, 3140F.

Now this wasn't scary as we have lots of protocols, training, and plans, and back up plans in place. As well as fire fighting systems like Halon systems, Air vents, AFFF (Firefighting foam) and Advance fire sprinkling systems designed to not only put out these fires but in a matter of minutes actually reduce the heat to cool temperatures. So putting actual people in these situations is rare.

Then they decided to test a berthing fire. Berthing fires are predicted to be at a lot lower temperature, but usually the plans and simulations are done with empty berthings. Then they decided to test what would happen with one that was setup to simulate actual living conditions. Beds, magazines, clothes, blankets, toiletries were all set up and then lit on fire. If I remember correctly the fire got up to 100K or 1340 F this was almost twice what the expected temps were. After this the Navy conducted an investigation into some ships to see what was being stored in berthings. They found stuff like fireworks, lighter fluids, paint cans, aerosol cans, liquor, and even cans of diesel fuel, a guy was into those rc cars that used real fuel and had two gallons in his locker. All these pointed to a real chance of not only a fire but a fire at temperatures, intensity, and speeds that the Navy was not training or preparing for.

Of course no amount of training can prepare for ignorance, neglect and, people who don't follow proper protocols and procedures. As is the case in the fire aboard the USS George Washington, the largest shipboard fire in recent memory that caused $70 million in damage and was caused by a sailor smoking in an unauthorized space that contained flammables that were improperly stored.
