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. … In most cases the fire will extinguish after a reduction …
Why is nitrogen gas not used in fire extinguishers? – Quora
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.

Is your fire extinguisher as operated as you think?
But if you haven’t inspected the extinguisher recently, it may not be as operational as you think—and could even pose a danger to you or others attempting to us it. Most dry-chemical fire extinguishers come with a pressure gauge that indicates whether or not the extinguisher is properly pressurized.
What happens if there is not enough pressure on a fire extinguisher?
If you waste time trying to find another extinguisher or another way to extinguish the fire because your portable extinguisher didn’t have enough pressure, the fire is simply getting larger and more difficult to control. In some cases, such as with cooking fires, this is even more dangerous.
Why is propane not used as a fire extinguishing agent?
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.
