How much force does a fire extinguisher produce? Water fire extinguishers are pressurized with air to approximately 150 pounds per square inch (psi)—five times a car tire pressure—from a compressor. A squeeze-grip handle operates a spring-loaded valve threaded into the pressure cylinder. How much pressure is in a fire extinguisher?
Heat. The purpose of a fire extinguisher is to break this process by removing or blocking one of these three elements. Once this happens, the fire will either extinguish immediately or burn out. To remove heat, a fire extinguisher can smother the fire. To remove oxygen, the fire extinguisher can smother it as well.
Pressure of a Fire Extinguisher – The Physics Factbook
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. The ones they use in firehouses are 690 kPa but the pressure in carbon dioxide extinguishers can go up to 5861 kPa.
How Many PSI Does a Fire Extinguisher Have? Fire extinguisher PSI ranges from 100 PSI up to 850 PSI depending on the contents and size of the extinguisher. Fire extinguishers of certain types tend to have PSI’s that fall within a certain range.

What happens when a fire extinguisher explodes?
Fire extinguishers are made to help put fires out and protect anyone nearby from any harm. However, fire extinguishers can also cause injury or physical damage under some circumstances. One is when a fire extinguisher explodes.
What makes a fire extinguisher less capable?
There are other ways to render a fire extinguisher less capable. For instance, blockage by the extinguishing agent inside hoses, springs, gaskets, and O-rings after being partially used can make it less effective.
