They don't, but fire catastrophes are one of the most gruesome ways to die - and worse, a fire can always spread around and endanger even more people. There are reasons why fire codes are among the oldest laws in humanity.
A good advice is to remember that in case of fire what kills people most of the times, is the smoke. Having extinguishers -and- breathing bottles could help. Maybe there is room for designing a new product that would act as two in one?.
