It's like purgatory! The mountain fire in southwest France has evacuated 10 thousand people. Why is it difficult to put them out?

The reason why the mountain fire is difficult to put out is mainly because of the dense vegetation on the mountain. Whenever there is a fire, the nearby vegetation will be implicated. Coupled with the complex terrain on the mountain, once a high temperature environment is formed, mountain fires will spread rapidly and it will be difficult to put out in a short time. ?

How to put out mountain fires?

At present, the method of extinguishing mountain fires is mainly carried out by firefighters combined with tools, and the fire is extinguished by spraying water, chemicals or wet soil on the surface of burning objects to cool down. Barrier measures can also be taken to separate fire from combustible materials and combustible materials from unburned materials. It can also reduce the oxygen content in the air below a certain oxygen content, isolate the air, and thus suffocate the fire. But generally speaking, putting out a fire requires a lot of manpower and material resources, and often involves hundreds or even thousands of people.

How to escape from the mountain fire?

When escaping, avoid escaping with the wind and choose the direction with the wind, otherwise it will easily cause casualties. Escape from the mountain, never run to the top of the mountain, otherwise it will easily cause casualties. The fire spread rapidly on the mountain, mainly due to the warm air rising against the wind, which led to the rapid upward spread of the fire. The steeper the fire, the faster it spreads; The fire spread at a moderate speed on the flat ground; The flame descends the slowest.

What are the main causes of mountain fires?

The most important factor that causes mountain fires is climate, and climatic conditions determine the scope and stage of forest fires. As for China, fires mainly occur in spring and summer in the northern Qinling Mountains, because the climate in spring and summer is dry and the water content of plants is low, which is easy to cause fires. Burning in the southern foot of Qinling Mountains, fires often occur in winter and spring when the climate is relatively dry. In areas where there are only rainy and dry seasons, forest fires mostly occur in dry seasons. Secondly, the combustible substances in the forest include all trees, shrubs, herbs, lichens, litter, humus and peat. Combustible is the basic component of forest fire and the main factor of fire spread.
