Could a dry ice bomb be used to put out a fire?

I'm going to give it a mythbusters answer of plausible in an highly unlikely and artificial case. Not in real life. HIGHLY NOT RECOMMENDED. DON'T DO IT! An explosion is what you want to prevent. I imagine your CO2 bomb would most likely act like…. a frozen turkey in a turkey fryer. read more

For a forest fire, you usually use water. With water you can open a valve and the water flows out, but with dry ice, even as pellets, you would need something like bomb bay doors to drop them out. In addition, since it sublimes to form a gas, it would start blowing away in the wind as soon as it turned to a gas. read more

Dry ice dumped on a fire would quickly turn to carbon dioxide gas. CO2 is good for extinguishing fires because it deprives the fire of oxygen. Flooding a room with CO2 will put a fire out by displacing the oxygen. read more

The dry Ice (CO2 at -55°C) would absorb a lot of heat that the fire is giving off robbing it of heating the surroundings. This would lead to a slower progression of the fire. Additionally, when it boils away it turns into gaseous carbon dioxide that suffocates the fire. read more
