Why is CO2 used in fire extinguishers instead of nitrogen? Carbon dioxide is the most commonly used “inert” gas extinguishing agent, followed by nitrogen (Friedman 1992). … However, because carbon dioxide is 1.57 times heavier than nitrogen [44 and 28 molecular weight (MW) , respectively] for a given volume, the two gases have nearly equivalent effectiveness on …
CO2 fire extinguishers as I mentioned above work by smoother the flames in CO2 cutting off access to oxygen interrupting the chemical reaction making the fire. However if the fire has an oxidizing chemical already present besides oxygen such as a powdered nitrates, sodium perchlorate, bromine, or other chemicals that act as oxidizers the fire doesn’t need ambient …
Why Is Carbon Dioxide Used in Fire Extinguishers?

Why Carbon dioxide is used in fire extinguishers instead of nitrogen? The primary reason why CO2 is used as an extinguisher is that it’s denser than air, and hence displaces possible supply of O2 to the source of our deadly fire by forming a sort of a ‘blanket’ around it…. Now, density of N2 is around 1.2 kg/m^3, whereas density of CO2 is around 1.98 kg/m^3….

What happens if you put O2 in a fire extinguisher?
O2 is oxygen. Fire needs oxygen to live. Adding more oxygen would just cause the fire to grow to a rather large size. The co2 replaces the oxygen thus extinguishing the fire.
Why are fire extinguishers not suitable for chemical fires?
These extinguishers are not suitable for chemical or electrical fires since the liquid can conduct electricity and cause flammable agents to spread. Other extinguishers coat the fuel, forming a barrier between the flammable material and the oxygen in the surrounding air.
