How does a gas fire extinguisher work?
Commonly, in modern times, fire extinguishers will use a blast of gas, such as nitrogen or carbon dioxide to spray a flame-retardant powder (such as sodium bicarbonate, or monoammonium phosphate). The gas displaces oxygen and cools the fuel, which is usually enough to put out a small flame, while the powder helps to smother It varies.

What is a CO2 fire extinguisher?
A carbon dioxide fire extinguisher (CO2) is one of the cleanest types of extinguishers to use as it leaves no residue and requires no cleanup. The CO2 extinguisher does exactly that – extinguishes CO2. By doing so, it removes oxygen from the fire, effectively suffocating it of oxygen.
