air nearest the floor is the coolest. It is, of course. But it is also loaded with distillation gases which, being heavier than air, seek the lowest level. Hydrogen sulfide is one of these. In the early stages of a fire the air you get in a crouched position is probably the least harmful.
One help for getting through smoke is the knowledge of how to hold your breath properly. Most people just gulp in a single deep draught of fresh air, then hold it as long as possible—30 to 60 seconds. This is illogical, because it allows carbon dioxide to build up in the lungs, and C02 is what compels you to breathe.
It is much better to overbreathe for a minute or two-—that is, inhale twice as deeply and twice as fast as normal. This expends your carbon dioxide so completely that you won’t want to breathe for an equivalent length of time. Even after the desire to exhale returns, you can hold your breath for the usual 30 to 60 seconds additional, if need be.
Remember that carbon monoxide, even in slight doses, derails your reasoning power. It’s pathetic how many bodies firemen recover of those who, in blind unreason, dashed back into the house they’d just escaped from. So, above all, once you’re out of a burning building, never, go back!
