Background

Forest fires are suppressed (forest fire suppression), i.e. measures taken to control and extinguish the forest fire, with the aim of minimising the losses caused by the fire.

Because the occurrence of forest fires is conditioned by the presence of combustibles, oxygen (comburent) and a fire source, the extinguishing measures to be taken should be able to isolate the combustibles or reduce the steam content of the combustibles to below the lower limit of ignition; isolating air or making the oxygen content in air lower than 14-18%; the temperature of the combustibles should also be reduced below the ignition point. According to the principle, various forest fire suppression methods can be summarized as follows: (1) asphyxia method: such as soil covering, fire extinguishing agent spraying, and beating, etc., can isolate the air needed by combustion, thereby achieving the aim of fire extinguishing. Is suitable for the early stage of fire. (2) Cooling method: that is, wet soil, water, etc. are covered on the inflammable matter to lower the temperature of the inflammable matter below the ignition point, so as to extinguish the fire. (3) Isolating combustibles: if a fire-proof wire is arranged, the burnt combustible material and the unburned combustible material are thoroughly separated; spraying chemical retarder on the surface of combustible material or watering to form fire-retarding belt to make it fire-retarding or non-inflammable. The means adopted in the extinguishing process can be classified into a direct extinguishing method, an indirect extinguishing method, aviation fire extinguishing and artificial rainfall fire extinguishing.
