A long time ago I was trained to be an officer on commercial oceangoing ships. In addition to regular classwork and practice with firefighting equipment, we were sent to Military Sealift Command Firefighting school to get experience fighting fires in actual shipboard conditions. It's a bit more than "cursory training." I'm not sure everyone came back with all their eyebrows intact :-) Not an expert firefighter by any means, even back then. Just responding to this to add some data. Still, you make a good point: if you're not regularly fighting fires, that training atrophies like anything else. If fire like this breaks out anywhere but on the main deck, my guess is that they'd just flood the space with CO2.
