After the firefighters arrive at the scene of fire, the commander should organize the fighting according to different situations.
1, hit the beginning of the fire: this is the key to extinguish forest fires, small fire is not extinguished into a fire, the fire must be controlled within a certain range, by the head of the fire, do not let it expand, do “hit early, hit small, hit” there is no fire disaster.
① play early: early discovery, early report, early out, early out, concentrated personnel to eliminate the fire in the initial stage.
② dozen small: control the fire first, and strive to make the fire smaller fire.
(3) dozen: what is called a dozen, after the fire is extinguished, thoroughly clean up the fire, prevent the resurgence of death, nothing is called a dozen.
2, hit the ground fire: this fire is mainly in the woodland weeds, miscellaneous irrigation, dead branches, leaves burning up, it spread burning speed.On the one hand, you can use branches and No.2 tools to beat the flame along the fire line to control the burning speed. On the other hand, you can choose the appropriate distance from the fire head to open a fire isolation belt to prevent the spread of the fire.
It is difficult to control the fire with simple tools when the fire is fierce and the wind is strong, so we have to open up temporary fire protection lines along the direction of the fire, or rely on the favorable terrain such as path and ridge, to prevent the spread of the fire. When necessary, we can take measures to fight the fire with fire.
3, hit the tree crown fire: larger ground fire in the role of wind, wind to help the fire, fire to help the wind, the fire becomes extremely fierce, along the tree crown into pieces burned in the past, the fight is also very difficult.This situation is mainly open fire road, with a chainsaw quickly cut down all the trees on the isolation belt, down to the side of the fire, timely cleaning debris, to prevent the spread of forest fire.(case)
The width of the barrier belt should be 5-10 meters. At the same time, the fire extinguishers should guard the fire road separately. When the fire head is close to the fire, the fire is blocked and weakened, and the flames near the fire road should be immediately defeated.
4, hit the mountain fire: also called the sky fire.The commander should pay great attention to this kind of fire extinguishment. He can track the extinguishment along the direction of the mountain from both sides of the fire line, adopt the propulsion method, and retreat to the burned place as soon as danger is encountered.
5, down the mountain fire: for the next mountain fire it burning speed is slow, can be used lighting tools directly beat, the fire is slow and easy to beat, the first person hit after others, because the fire in front of the people knocked down, Mars will not immediately extinguish, sometimes will return, so should be followed by play.First of all, we should stop the head of the fire, but not face to face. We should hit from both sides of the head of the fire. We should adopt the method of “light lifting, heavy pressure and urgent beating”.Is to lift light, a dozen a drag, not straight up and down, so as not to fan the fire and sparks flying.The pressure should be heavy, so that the fire smothers out.Beat quickly and try to put out the embers by moving or sweeping the branches left and right.If the line of fire into a straight line, you can divide the manpower into several groups, cut the line of fire into two or several sections, segmenting beat.If the fire line burns into an arc state (that is, the two sides burn fast, the middle burn slowly), the fire head should be controlled from both ends, and the fire should be hit from both ends to stop its spread and expand, and the fire line should be gradually shortened until the fire is extinguished. Never hit the fire from the middle first, so as not to burn the two sides fast and encircling the lighters in the middle and cause danger.This kindling method is usually used when there are many people and the fire is not big.
6. Fight a night fire.The relative humidity is small, the wind is small and the spread speed is slow, as long as the command is proper, according to the tactics of playing “under the mountain fire”, can be quickly extinguished.If the fire is larger, night day black hill steep, is generally around and do not play, and then fight after dawn.
