Fire fighters have oxygen on their backs right? How does it not explode when they go into a burning building?
In: Chemistry
Fire needs oxygen, fuel, and heat. Inside the canister there is only compressed air with no fuel, and if the canister was hot enough to burn inside then the guy wearing it has already melted off his skin. There is a risk of it getting hot enough that the pressure increases and it bursts, but they have safety features which will let the air out before the whole can breaks.
