Nitrogen liquifies at very low temperatures. Further, it will require specific insulation (and costly!) to keep it in the liquid state. While Carbon Dioxide is both easier to liquify and store
Nitrogen can be used in fire extinguishers as gas propellant.
N2, you know nitrogen gas
You need to use a Class B extinguisher on flammable liquids.
A class C fire extinguisher is used for electrical fires. A all purpose A, B, C extinguisher can also be used.
Fire extinguisher
Yes. They are rated for the type of fire they can be used against, and the capacity of the extinguisher.
Do you mean why is nitrogen not used as a fire extinguisher? Well, it SORT of is. Nitrogen gas can be used for blanketing a process, to exclude oxygen. But nitrogen is lightly lighter than air, and tends to float away easily. Carbon Dioxide, the most common fire extinguishing gas, is very heavy, and lays on top of the fire. Carbon Dioxide is much easier to keep liquid at room temperature- meaning an extinguisher will hold much more CO2 than N2.

The gas used in fire extinguishers is carbon dioxide. That is only for a CO2 extinguishers High pressure and no Gauge on the unit(about 2000psi). Normal Dry chemical extinguisher ABC, BC (195psi)Use Nitrogen as the propellent.
