Chemistry: Connections to our changing world. Prentice Hall, Upper Saddle River, . "The nitrogen gas inside a fire extinguisher is pressurized to 1345 kPa". 1345 kPa. Fire Extinguisher Safety Tips. Roswell Online 1997. "The pressure inside an extinguisher can be as high as 200 psi". 1379 kPa.
There is not one set pressure for all fire extinguishers, they vary by class. The ones they use in firehouses are 690 kPa but the pressure in carbon dioxide extinguishers can go up to 5861 kPa. Also Know, how do you pressurize a water fire extinguisher?

The typical residential or consumer fire extinguisher comes with this warning and a pressure gauge to ensure that it is in a safe zone and prepared for use should the occasion arise. An extinguisher designed for use with a …
CO2 gas is held in the fire extinguisher under pressure, normally around 55 bars at room temperature. By comparison, pressure cookers operate at 1 bar of pressure, modern car tyres are usually inflated to a maximum of 2.5 …

What is the pressure of a fire extinguisher?
There is not one set pressure for all fire extinguishers, they vary by class. The ones they use in firehouses are 690 kPa but the pressure in carbon dioxide extinguishers can go up to 5861 kPa.
How does a fire extinguisher compare to a pressure cooker?
By comparison, pressure cookers operate at 1 bar of pressure, modern car tyres are usually inflated to a maximum of 2.5 bars, whilst airliner tyres are inflated at up to 14 bars. At a pressure of 55bars, around two-thirds of a carbon dioxide fire extinguisher’s contents are in a liquid state, with a gaseous top layer.
How does a fire extinguisher work?
The fire extinguisher is sealed by a sophisticated valve mechanism to maintain the required pressure, which is indicated by a pressure gauge on the valve body. CO2 is only released when the safety pin or clip is removed, and the fire extinguisher handles are squeezed together.
How far does a gas fire extinguisher work?
Since the gas disperses quickly, this type of fire extinguisher is only effective from 3 to 8 feet. There is not one set pressure for all fire extinguishers, they vary by class.
