Self-help in the event of natural disasters
Natural disasters are those caused by natural phenomena such as floods, earthquakes and typhoons. With current levels of science and technology and capabilities, one cannot prevent the occurrence of natural disasters ... Or fully withstand their destruction. However, positive and effective measures to minimize damage can only be taken in accordance with the pattern and characteristics of natural disasters。
How can tropical storms be mitigated
Tropical storms often occur in coastal areas, causing severe winds, heavy rains and waves, which have a strong destructive effect on coastal urban facilities, sea vessels and agricultural production in coastal areas. How do we mitigate the effects of tropical storms on people themselves
1. Pay attention to weather forecasts and prepare for prevention。
2. Houses need to be reinforced in a timely manner and doors and windows closed。
3. The preparation of food, drinking water, lighting, rain and necessary medicines to prevent uncertainty。
4. Access to drainage and drainage facilities。
5. When tropical storms arrive, stay indoors to the extent possible and reduce outages。
6. In the event of a thunderstorm, be careful to use electrical appliances and to protect against tentacles。
7. Closely monitor the surrounding environment and move in a timely manner in cases of flooding and landslides that threaten housing security。
8. In the aftermath of the storm, attention should be paid to health prevention and to reducing the spread of disease。
How to escape the cyclone
Tornadoes are very powerful cyclones, mostly in spring. Tornados often come very quickly, suddenly and with huge noises. Its destructive power is such that it can involve sandstones, trees, crops and even fish in the sea and goods in warehouses in areas it passes through, and poses a great threat to the lives and property of people. How can you protect yourself effectively when a tornado strikes
1. When a cyclone strikes, the doors and windows shall be opened to balance the air pressure inside and outside the house, in order to avoid the wind lifting off the roof and blowing down the wall。
2. In the interior, the person shall secure the head and lay down against the wall。
3. When encountered in the field by a tornado, it shall move quickly in the opposite direction or sidewardly to escape。
4. When the cyclone has arrived, the low-lying terrain should be sought, with closed mouths, eyes, hands and arms to protect the head from damage by coming objects。
5. If a tornado is encountered in a car, it should be taken out of the car and not left behind。
How can you save yourself in a flood
In a short period of time, heavy rainfall in an area will cause the river to rise sharply, flooding its dams, flooding its agricultural land, villages and destroying its roads, bridges and houses. There was a flood. How can you save yourself
L. Threatened by floods and, if sufficient time is available, in accordance with predefined routes, there shall be an organized transfer to the slopes, highlands, etc., and, in case of surprise and already surrounded by floods, water transfers shall be made from ships, rows, boards, wooden beds, etc., to the extent possible。
2. The flood came too soon and, when it was too late to move, it was necessary to climb the roof, the buildings, the trees, the walls, to take temporary refuge and wait for help. Don't travel alone。
3. In mountain areas, heavy rainfall can easily lead to flash floods. In such cases, care should be taken to avoid crossing rivers in order to prevent them from being washed away, as well as to prevent damage from landslides, rollers and mudslides。
4. High-pressure line iron towers are found to be dumped, lined down or broken; to avoid risk, they cannot be touched or approached to prevent electrocution。
5. Following the floods, epidemiological drugs are used to prevent epidemics and to prevent infectious diseases。
How do you protect yourself from snow and hail
Snowstorms and hails are common and, while not necessarily catastrophic, care should be taken to protect themselves:
L. On snowy days, care should be taken to add clothing and keep warm; to reduce outdoor activity and avoid freezing。

How can you avoid lightning while going out
Thunder is a common natural phenomenon, which is essentially a spark discharge in a thunderstorm cloud in the sky, where light comes from lightning, where lightning causes the air to swell rapidly with heat, and where thunderstorms are prone to lightning, causing injury or even death. Avoiding lightning strikes should:
In the event of a thunderstorm on the way out, do not stop in the open field in time to escape。
2. When thunderstorms come together, if there is nowhere to hide in the open field, then every effort should be made to find a low dent (e. G. A pit) to hide, or to get down immediately, to close your feet, to hold your knees and to fall down on your head, with a minimum height. If objects in hand with electrical power (e. G. Shovels, metal pole umbrellas) are to be thrown quickly to a distance, they must not run in the open, otherwise they will be targeted by lightning。
3. Particular care should be taken that, in the event of lightning, no high objects (e. G. Flag poles, trees, chimneys, poles) are allowed to stand; these places are most vulnerable to the threat of lightning。
