There are four commonly used methods of extinguishing fire: isolation method, suffocation method, cooling method, and chemical suppression method.

(1) Asphyxiation method: By isolating air and separating combustion supporting gases (such as oxygen) from combustibles, combustion can be stopped.

(2) Cooling method: Reduce the temperature of the combustion material, and when it falls below the ignition point, stop burning.

(3) Isolation method: Separate burning substances from unburned substances to isolate the fire and prevent it from spreading.

(4) Chemical inhibition method: Use chemical agents containing fluorine, chlorine, and odor to interrupt the chain reaction and stop combustion.

So when we encounter a fire, don't be nervous or afraid. Remember these 4 common methods and face it calmly
