Fire extinguisher, compact or portable appliance used to extinguish a small fire by guiding a liquid onto it that cools the burning material, deprives the fires of oxygen or interferes with the chemical reactions that occur in the fire.
Types of fire extinguisher
Fire extinguishers, which are the most common, are simply fire-filled tanks with compressed (tightly squeezed) air as the propellant to carry them out. Fire extinguishers operate by taking heat out of the flames.
Dry chemical extinguishers are foam tanks or dry powder covering compressed nitrogen as the propellant. You work by restricting the fire: when you residence a coating of powder or spray on the fire, you cut off the fuel after the ambient oxygen, and the fire goes out.
The extinguishers produce a combination of liquid and gaseous carbon dioxide (non-flammable gas). Usually CO2 is a gas at atmospheric temperature and pressure. For order to make it a liquid it must be held under high pressure. The gas spreads tremendously as you release the pressure, which makes a huge white jet. CO2 affects the triangle of fire in two ways: it smoothes the oxygen and when it turns up
How do fire extinguishers work?
