My brother told me that it people smoking caught stuff on fire all the time on ships. I know they have designated "smoking areas", but the extent to which smoking is rampant in the military and anything associated with it, is absolutely staggering IME. It all kind of stems from the "don't worry about your body now, push it to the max", which includes drinking, medical issues that show up later in life, inappropriate diagnoses and treatments, and so on. Command does little to discourage it and they tend to see it as a "right" that these people "need to be able to smoke", so the inevitable outcome is fires caused by people smoking in areas they shouldn't be. Of course, there are plenty of other sources of fire...but this is one of the common ones...
