The basic methods of fire fighting mainly include

The basic methods of fire extinguishing include cooling fire extinguishing, suffocation fire extinguishing, isolation fire extinguishing and suppression fire extinguishing.

1, cooling fire extinguishing method: directly spray the fire extinguishing agent on the combustible material, so that the temperature of the combustible material is reduced below the self-ignition point, thus stopping the combustion. A preventive method of cooling unburned combustible substances with water to prevent them from reaching the ignition point and catching fire.

2. Asphyxiation fire extinguishing method: combustible materials cannot be burned when there is no air or the oxygen content in the air is lower than 14%. The so-called suffocation method is to cut off the air supply of combustion products.

3. Isolation fire extinguishing method: Combustible is one of the most important combustion conditions. If the combustible is isolated from the fire source or air, the combustion reaction will automatically stop.

4. Suppression fire extinguishing method: chemical fire extinguishing agent is sprayed into the combustion zone to participate in the combustion reaction, so that the chain reaction of free radicals (combustion chain) stops and the combustion reaction stops or cannot be sustained.
