Forest fire hazards
Forest fires refer to forests that are out of human control, spread and expand freely within the forest land, and bring certain harm and loss to the forest, forest ecosystem and human beings**. Forest fires are a kind ofIt is sudden, destructive, and extremely difficult to saveNatural disasters will not only burn down patches of forests and harm the animals in the forests, but also reduce the ability of forests to regenerate, cause soil impoverishment, destroy forest water conservation, and even lead to the loss of balance of the ecological environment, cause air pollution, and threaten the safety of people's lives and property.
The main cause of forest fires
There are two main types of forest fires: man-made fires and natural fires.
Man-made fires include the following:
Productive fire sources: fire for agriculture, forestry and animal husbandry, fire for forestry and sideline production, fire for industrial and mining transportation production, etc.;
Non-productive fire sources: such as outdoor smoking, cooking, paper burning, heating, etc.;
Intentional arson. Natural fire includes:
Thunder, lightning, fire, spontaneous combustion, etc.
There are several levels of forest fire warning
According to the forest fire danger level, fire behavior characteristics and the degree of harm that may be caused, the forest fire danger warning level is divided into four levels, which are used in order from high to lowRedOrange,YellowwithBlueDenote.
What are the basic principles of fighting forest fires
The basic principle of fighting forest fires is to "fight early, fight small, and fight small". Fighting early refers to putting out the fire in time, fighting small refers to fighting the fire that has just occurred, and hitting refers to the thoroughness of fighting the fire, not only to fight the open fire, but also to clean up the case fire and eliminate all the remaining fires. The three are interconnected and influence each other. Hitting early is the premise of extinguishing fires, hitting small is the key to extinguishing fires, and hitting is the core of fire extinguishing.
What are the precautions for escaping in the event of a forest fire?
One
The damage caused by forest fires to people mainly comes from high temperature, smoke and carbon monoxide, which can easily cause heat stroke, burns, suffocation or poisoning, especially carbon monoxide has latent nature, which will reduce people's mental acuity and is not easy to detect after poisoning. Therefore, if you find yourself in a forest fire area, you should use a wet towel to cover your mouth and nose, and if there is water nearby, it is best to soak your clothes to add an extra layer of protection.
II
In the event of a fire in the forest, you must pay close attention to the change of wind direction, because the wind direction determines the direction of the spread of the fire, and also determines the direction of escape. If you suddenly feel that there is no wind, you can't be careless, which often means that the wind direction will change or reverse, and once you can't escape, it is easy to cause **.
III
When smoke hits, cover your mouth and nose with a wet towel or clothing to quickly take shelter. If the evacuation is not timely, you should choose a flat ground where there is no combustible material nearby to avoid smoke. Do not choose low-lying land, potholes, or holes, because low-lying land, potholes, and holes are prone to soot deposits. If you are surrounded by fire in the middle of a mountain, you should run down the hill quickly, and do not run up the hill, as the fire usually spreads upwards much faster than a person.
Fourth
After successfully leaving the scene of a fire, take a break near the disaster site to prevent mosquitoes, snakes, wild animals, or poisonous bees. Friends traveling in groups or groups should check with each other to see if everyone is there, and if there are those who are left behind, they should promptly ask the local fire fighting and disaster relief personnel for help.
