A fire needs oxygen to burn. Air contains oxygen. So passing in nitrogen stops incoming air refuelling the fire. Have to be careful if there are trapped people who of course need to take in oxygen as they breathe.
Nitrogen can be used in fire extinguishers as gas propellant.

N2, you know nitrogen gas
Because nitrogen gas bigest quantity in air.
Any incombustible gas may extinguish a fire CO2, Nitrogen gas, and so on.
it depends how big the fire is
Nitrogen itself is not a flammable gas, so it will not support combustion. However, oxygen is necessary for a fire to burn, and air is composed mostly of nitrogen and oxygen. Removing oxygen, by displacing it with nitrogen, can help extinguish a fire.
Halon, CO2, Neon,Nitrogen
If nitrogen gas is used instead of an inert gas in the glass bulb of an electric lamp, the nitrogen gas can react with the filament material and cause it to deteriorate faster due to oxidation. This can result in a shorter lifespan for the electric lamp. Additionally, there might be a risk of fire or explosion due to the presence of oxygen in the nitrogen gas.
Nitrogen itself is not a fire extinguishing agent. However, nitrogen gas can displace oxygen, which is a crucial component for fire to sustain itself. By displacing oxygen, nitrogen can help smother a fire by depriving it of the necessary conditions to burn.
Yes, portable dry chemical fire extinguishers are pressurized by means of nitrogen (expellant gas used to discharge the extinguishing agent from its container). Carbon dioxide can also be used as expellant gas. Usually carbon dioxide is used for temperatures ranges of 0oC to +49oC, and nitrogen for extreme temperature ranges of -54oC to +99oC.
Nitrogen gas itself does not catch fire under normal conditions as it is an inert gas. However, nitrogen can support combustion by providing an oxygen-free environment that prevents the fire from being extinguished.
