Who can tell me something about forest fire prevention? The more, the better.

Common sense of forest fire prevention

First, the harm of forest fires

Forest fire is the most dangerous enemy and the most terrible disaster in forestry, which will bring the greatest harm and devastating consequences to the forest. Forest fire will not only burn patches of forest, harm the animals in the forest, but also reduce the regeneration ability of the forest, cause soil impoverishment, destroy the function of forest to conserve water, and even lead to imbalance of ecological environment. Despite the rapid development of science in the world today, human beings have not made great progress in putting out forest fires.

Second, the types and classification of forest fires

According to the burning position, spreading speed, damaged position and degree of forest fires, forest fires can be roughly divided into three categories: 1. Surface fire II. Crown fire 3. Underground fire.

According to the size of the affected forest area, forest fires are divided into the following four categories:

1. Forest fire: the affected forest area is less than 1 hectare or other woodlands catch fire (including yellow fire);

2. General forest fire: the affected forest area is more than 1 hectare and less than 100 hectare;

3. Major forest fires: the affected forest area is less than 1000 hectares1000 hectares;

4. Extraordinary forest fire: the affected forest area 1000 hectares or more;

Third, the causes of forest fires

There are two main causes of forest fires: man-made fires and natural fires.

(1) Man-made fires include the following types:

1. Productive fire sources: fire for agriculture, forestry and animal husbandry, fire for forestry sideline production, fire for industrial and mining transportation production, etc.

2. Unproductive fire sources: such as outdoor smoking, cooking, burning paper, heating, etc. ;

3. Intentional arson

Among the fires caused by man-made fire sources, forest fires caused by land reclamation and smoking are the most. In the forest fires in our city, the fires caused by smoking, burning wasteland and burning paper on graves account for an absolute number.

(2) Natural fire: including lightning fire and spontaneous combustion. Forest fires caused by natural fires account for about 1% of the total forest fires in China.

Four, three factors affecting the fire.

Temperature, humidity and unit combustible load.

Five, fighting forest fires

(A) how to strengthen safety measures when putting out the fire

Strengthen fire control organizations. One is to send comrades with fire fighting experience as front-line commanders. Second, the temporary organization of firefighters, must specify the section chief and team leader. The third is to clarify fire discipline and safety matters. The fourth is to check whether the fire-fighting equipment meets the requirements and whether the fire-fighting clothes are very loose and flame-retardant. Fifth, strengthen fire reconnaissance and organize fire communication, rescue and logistics support. The sixth is to enter the fire from the tail of the fire and fight along the two wings of the fire. Seventh, don't strike the fire head directly in the wind, don't strike the fire head up the mountain, don't strike the fire head on cliffs, steep slopes and broken terrain, don't put out the fire directly in windy weather and fire conditions, and don't put out the fire in places with dense combustibles. Eight is the correct use of fire fighting equipment.

(2) What are the ways to save yourself from danger?

Retreat to a safe area. The fire fighting team (group) should observe the changes of the fire scene when putting out the fire. In case of Fei Huo and cyclone, organize firefighters to enter burn areas, areas with less vegetation and low flame. The second is to ignite and save yourself according to the specifications. It is necessary to unify the command, choose a relatively flat place, and lie down to avoid danger according to regulations. In case of danger, you should lie down in a place with less vegetation nearby, with your feet facing the fire, pull open the floating soil until you see wet soil, bury your face in the pit, wrap your head with clothes and put your hands in front of your body. The fourth is to break the wind according to the norms. When the wind changes suddenly and the fire turns around, the commander should decisively give the order to break through, and the players themselves should make decisive decisions, choose places with less grass, wrap their heads with clothes, hold their breath and rush to break through in the wind. People should be able to break through in 7.5 seconds. Never race against the fire, only rush to it.
