If you have the training, been apprised of the situation, are wearing the right breathing equipment, and you have 4 bodies lying on the ground in front of you, then you have had all the warnings you could possibly expect to get. Disregarding safety in the face of so much evidence about the danger is either perverse or stupid. I can agree with your excuse for the other people (to some degree) but the fire chief doesn't get a pass on this one.
