Nitrogen is the most common propellant used in dry chemical, dry powder (Class D) and halon replacement extinguishers. It is not used as an extinguishing agent because of poor performance, even worse than CO2 which is the worst available- short range, lowest extinguishing capability and highly technique dependent.
Nitrogen is used to pressurize the extinguishers. Why nitrogen is not used in fire extinguisher? The extinguishing effect of inert gases such as argon, nitrogen and carbon dioxide (in principle, this is not an inert gas and is therefore unsuitable for class D fires) is achieved through the displacement of atmospheric oxygen . …

Which gas is used as a propelling agent in fire extinguishers?
Normally Carbon Di Oxide ( CO2) and Dry Nitrogen gas are used as a propelling agent in fire extinguishers. Normal air can also be used for pressurising an extinguisher and as a propellant. Halon gases were used as an extinguishing agent before the phase out started post signing of Montreal Protocol in 1991.
What is the difference between CO2 and AFFF fire extinguishers?
In Co2 type Fire extinguisher ,carbon dioxide is basically used to extinguish the fire by cooling method as all of you know that carbon dioxide is very cold (gas). AFFF concentration (Aqueous Film Forming Foam) is used in mechanical foam type Fire extinguishers, 2–3% concentrate with water is sufficient to make a Foam extinguisher reliable.
What is a powder extinguisher fire extinguisher?
Powder extinguishers fire extinguishers are pumped with gas (nitrogen, air, carbon dioxide) up to a pressure level of 16 ATM and charged with fire extinguishing powder.
