1. Basic methods for fighting forest fires
One is to save the method. The basic methods of fighting forest fire include artificial fighting, fighting with soil, fighting with water, fighting with gas, fighting with fire, opening fire prevention line to prevent fire spreading, artificial rainfall, wind extinguisher, chemical fire extinguishing, explosion fire extinguishing and aviation fire extinguishing.
The other is fire-fighting equipment. Mainly used for extinguishing fire and embers, open fire line of the machine. It includes pneumatic extinguisher, no.2 extinguisher, manual fire extinguisher, small water pump, water gun, machete, shovel, hoe and irrigation machine, chainsaw, saw, axe, hoe, etc.
Three is saves the form. One is a direct fire extinguishing method is to use fire fighting equipment directly with the fire, so that the fire stopped burning. This method is generally suitable for weak, moderate surface fire (people can be close to extinguish), is not suitable for intense fire or canopy fire. Direct fire extinguishing method USES many machines and tools, can use mechanical fire fighting tools, but also can use chemical fire extinguishing agents, water, soil. The second is indirect fire fighting method is mainly the establishment of fire isolation zone, such as open fire line, dig fire ditch, fire with fire. It is mainly suitable for fierce surface fire, crown fire and underground fire.
According to the law of forest fire occurrence and the characteristics of fighting fire, fighting forest fire must follow the procedure of "first control, then eliminate, then consolidate" and be carried out in stages. Four stages:
First, control the fire. That is the initial stage of fire fighting, but also the most urgent stage. Its main task is to block the fire, control the fire, the fire within a certain range.
Second, stabilize the fire. After sealing off the fire head and controlling the fire, more effective measures must be taken to flutter the fire wings and prevent the fire from spreading to the two sides. Is the most critical stage of fighting the fire.
Third, clean up the residual fire stage. When the fire is extinguished, patrol the burn site and immediately extinguish any remaining fire.
Fourth, watch the fire. The main task is to keep watch over the fire. In general, barren mountains and young woodland shall be kept under fire supervision for 12 hours, and those of medium age and mature woodland shall be kept under fire supervision for more than 24 hours before evacuation can be considered. The purpose is to prevent dead forest from resuming fire.
