Common sense of natural disaster prevention and control

1. Natural disasters and prevention. 1 According to what you have learned, judge the season with frequent thunderstorm weather and tell the reason.

May to September is the most frequent season for thunderstorm activity. According to the causes of lightning, the formation of thunderstorm clouds has certain conditions, that is, there must be enough water vapor in the air, which has the power to make wet air rise and the air can produce strong convection. In spring and summer, due to the influence of the warm and humid air flow in the south, the air is humid, and the solar radiation is strong. The air near the ground is constantly heating up, and the upper cold air sinks, which is easy to form strong convection, so there are many thunderstorms. Even hail. In winter, controlled by the continental cold air mass, the air is cold and dry, and the solar radiation is weak, so the air is not easy to form violent convection, so there are few thunderstorms, not to mention hail. But sometimes the weather is warmer in winter, and the warm and humid airflow is stronger. When there is occasional strong cold air going south in the north, warm and humid air is forced to rise and convection is intensified. Thundershowers can also be formed, and the warm and humid airflow is particularly strong, and the convection is particularly strong, and hail can also be formed. There is a phenomenon of "thunder and winter". Ii. measures: 1. Don't run in the wilderness, don't ride a bike or motorcycle. Second, don't shelter from the rain under trees and telephone poles, and stay away from trees. Third, don't touch the power switch and electrical equipment. Fourth, people don't stand under electric lights or take elevators.

2. Knowledge of natural disaster prevention

1, lightning disaster and prevention (1) In lightning weather, stay indoors and close doors and windows; People who work outdoors should hide in buildings.

(2) TV, audio and other electrical appliances with no or insufficient lightning protection measures should not be used, and faucets should not be used. (3) Do not touch antennas, water pipes, barbed wire, metal doors and windows, building external walls, and stay away from live equipment such as wires or other similar metal devices in thunderstorm weather.

2. Earthquake Disaster and Prevention (1) Classroom lighting E5a48de588B67A 643133366306432, laboratory cabinets and library bookshelves should be fixed. (2) hide under the table with your back to the window during the earthquake and protect your head with a schoolbag.

(3) Don't rush out of the classroom during the earthquake, and avoid rushing up and down the stairs. 3. Tropical Storm Disaster and Prevention (1) Pay attention to the weather forecast and do a good job in prevention and preparation.

(2) The parts of the house that need to be reinforced should be reinforced in time, and the doors and windows should be closed. (3) Prepare food, drinking water, lighting, rain gear and necessary medicines to prevent accidents.

(4) Dredge the drainage facilities and keep them unobstructed. 4. Tornado Disaster and Prevention (1) When a tornado strikes, doors and windows should be opened to balance the indoor and outdoor air pressure to avoid the wind blowing off the roof and knocking down the walls.

(2) indoors, people should protect their heads and squat down facing the wall. (3) When encountering a tornado in the wild, you should quickly move in the opposite direction or sideways to avoid it.

5. Flood disaster and prevention (1) are threatened by floods. If there is enough time, we should move to hillsides and highlands in an organized way according to the predetermined route; In the case of being caught off guard and surrounded by floods, we should use boats, rafts, door panels, wooden beds, etc. Let the water transfer as much as possible. (2) When the flood comes too fast to move, you should immediately climb the roof, the roof, the big trees and the high walls, take refuge temporarily and wait for rescue. Don't swim alone to transfer.

3. Natural disaster protection knowledge

1. How to organize personnel protection when there is a strong wind attack? Before the strong wind comes, it is necessary to move to a safe place in time to avoid buildings and high-altitude facilities that are easy to cause casualties, and never take shelter from the wind and rain in the above places; Construction enterprises should fix flowerpots and other items in time, and arrange and pile up construction equipment, tools and materials to ensure safety.

Avoid walking on dams and bridges near rivers, rivers, lakes and seas. Ships return to Hong Kong to take shelter from the wind and anchor, people go ashore to take shelter from the wind, and vehicles avoid driving in strong winds. 2. How do you organize protection in case of rainstorm? In places prone to heavy rain, it is necessary to strengthen self-prevention awareness and transfer personnel to safe places.

Heavy rain may cause accidents in water conservancy projects. In case of danger, people should move to safe places. Once there are signs of geological disasters such as landslides and mudslides, do a good job of evacuation in time. 3. When there is a storm surge, how do people organize protection? Storm surge is easy to damage seawalls, culverts, docks, revetments and other facilities. Before the typhoon comes, people who are in danger of planting outside the pond should be moved to safety in time.

4. How to organize protection before the flood? It is necessary to issue flood warnings to the public through various channels and use all means of transportation to evacuate the masses. 5. When a flood occurs, how do residents organize protection? When the flood rises, the power supply and gas should be cut off, residents in low-lying areas should move to high places, and people in low-rise houses should move to high places; You can also climb trees and use floating objects to escape.

4. Preventive measures against natural disasters

(1) Adhere to the principle of putting people first, giving priority to prevention and combining avoidance with treatment.

Strengthen the prevention and control work such as investigation, monitoring, early warning and forecasting, publicity and training, and change passive emergency avoidance into active disaster reduction and prevention, so that the prevention and control of natural disasters can be coordinated and unified, and the losses caused by natural disasters can be avoided and alleviated to the maximum extent. (2) Adhere to the principle of proceeding from reality.

Closely combined with the actual situation of engineering construction and the overall requirements of construction, the prevention and control tasks will be included in the project development and construction plan. The prevention and control of natural disasters should be combined with engineering construction, village and town construction, mountain resources development and ecological environment protection and management, so as to realize the unity of the three benefits of "society, economy and ecology".

(3) Adhere to the principle of overall planning, highlighting key points and implementing by stages. Focusing on the prevention and control of natural disasters in prone areas, we will mainly arrange the exploration and control of important natural disasters that seriously threaten the engineering construction and the safety of people's lives and property in the near future.

Do the combination of short-term and long-term, local prevention and control and regional environmental governance. (4) Adhere to the principles of technological innovation and institutional innovation.

Adhere to the combination of mass monitoring and professional monitoring, apply new theories to study natural disasters, use new technologies and methods to monitor and control natural disasters, and establish a scientific system to adapt to the prevention and control of natural disasters in the engineering area. (5) Adhere to the principle of multi-channel financing.

Increase investment in natural disaster prevention and control. For natural disasters caused by human activities such as engineering construction, the responsible unit shall bear the responsibility for governance; If other natural disasters caused by natural factors really need to be treated, the treatment of natural disasters shall be carried out according to the principle of * * * or the owner's contribution. Extended data:

Natural disasters refer to natural phenomena that endanger human survival or destroy human living environment, including drought, high temperature, low temperature, cold wave, flood, waterlogging, mountain torrents, typhoons, tornadoes, fire tornadoes, hail, wind hail, frost, rainstorm, blizzard, freezing rain, acid rain, fog, strong wind, icing, haze, smoke, floating dust, sand blowing and sandstorm.

The characteristics of natural disasters can be summarized into six aspects: first, the extensiveness and regionality of natural disasters. On the one hand, natural disasters are widely distributed.

Whether it is the sea or the land, the ground or the underground, the city or the countryside, the plain or the hilly area or the plateau, as long as there are human activities, natural disasters may occur. On the other hand, the regionality of natural geographical environment determines the regionality of natural disasters.

Secondly, natural disasters are frequent and uncertain, and there are many large and small natural disasters all over the world every year. In recent decades, the frequency of natural disasters has increased, and the uncertainty of the time, place and scale of natural disasters has greatly increased the difficulty for people to resist natural disasters.

Third, natural disasters have a certain periodicity and are not heavy. E799BE5BAA6E997AEE7ad94EB893E5b19E3133336303232, the occurrence of major natural disasters, whether earthquakes, droughts or floods, presents a certain periodicity. People often say that a natural disaster "once in ten years, once in a hundred years" is actually a popular description of the periodicity of natural disasters. The non-repetition of natural disasters mainly refers to the non-repetition of disaster processes and destruction results.

Fourth, related to natural disasters. The connection between natural disasters is manifested in two aspects.

On the one hand, there are links between regions. For example, the "El Nino" phenomenon on the west coast of South America may lead to global meteorological disorder; Industrial waste gas from the United States often forms acid rain in Canada.

On the other hand, disasters are related. In other words, some natural disasters can be mutually conditional, forming a disaster group or chain.

For example, volcanic activity is a disaster group or chain. Volcanic activity will lead to a series of disasters such as volcanic eruption, melting of ice and snow, debris flow and air pollution.

Fifth, the harm caused by various natural disasters is serious. For example, there are about 5 million earthquakes recorded every year in the world, including about 50,000 felt earthquakes and nearly 1000 damaged earthquakes. However, strong earthquakes with a magnitude of more than 7 on the Richter scale can cause great losses, about 15 times a year, and the economic losses caused by droughts and floods are also very serious, reaching tens of billions of dollars worldwide every year.

Sixth, natural disasters are inevitable and can be alleviated. Because man and nature are always contradictory, as long as the earth is moving and the matter is changing, as long as human beings exist, natural disasters cannot disappear. From this perspective, natural disasters are inevitable.

However, intelligent human beings can prevent and reduce disasters in a wider and wider scope, and minimize disaster losses by taking measures such as seeking advantages and avoiding disadvantages, turning harm into benefits, and turning harm into benefits. From this perspective, natural disasters can be alleviated. For families and individuals in disaster areas, we should pay attention to the following points: ① Pay attention to the cleanliness of drinking water. If possible, strictly disinfect it with drugs according to the guidance of disaster relief personnel. If not, try to boil water before drinking it. Never quote contaminated water casually because of trouble.

(2) Cooperate with disaster relief personnel to kill flies, mosquitoes and rats and do everything possible to prevent mosquito bites. (3) found abnormal situation, such as someone around sick, have a fever, suffering from skin diseases, etc. , should immediately report to the disaster relief personnel or relevant departments.

(4) Try to avoid multiple people living in the same room, and try to avoid sleeping with animals, even their own poultry and livestock. ⑤ Unless necessary, don't move at will without the organization and guidance of relevant personnel.

People who go out should not rush into the disaster area because they care about the safety of their relatives and friends. ⑥ When the supply of tap water and other water sources is interrupted after the disaster and residents need to drink groundwater, fire water and other water, attention should be paid to ensuring the safety of drinking water.

If the tap water supply is interrupted after the disaster, bottled water should be given priority, or boiled at a designated place.

When the typhoon center passes by, the wind will decrease or stay still for a period of time. Remember that strong winds will blow suddenly, and you should continue to stay in a safe place to avoid the wind; Other orange warning signals of the same typhoon.

Two, the rainstorm warning signal is divided into three levels, respectively, with yellow, orange and red. The competent meteorological departments at the provincial level in Northwest China and Qinghai-Tibet Plateau may formulate rainstorm warning standards according to the actual situation and report them to the China Meteorological Bureau for approval before implementation.

(1) yellow rainstorm warning signal meaning: within 6 hours, the rainfall will reach more than 50 mm, or it has reached more than 50 mm and the rainfall may continue. Guide to defense: 1.

(2) The meaning of rainstorm orange warning signal: within three hours, the rainfall will reach more than 50 mm, or it has reached more than 50 mm and the rainfall may continue. Defense Guide: 1, suspend outdoor work in open air, and stay indoors or in a safe place to avoid rain as much as possible; 2. Relevant emergency departments and rescue units should strengthen their duty, closely monitor the disaster situation, cut off dangerous outdoor power supply in low-lying areas, and implement countermeasures; 3. Traffic management departments should implement traffic guidance or control in areas with accumulated water; 4. Move dangerous areas and dangerous residents to safe places for shelter from the rain; Others use yellow rainstorm warning signals.

(3) red warning signal meaning of rainstorm: the rainfall in three hours will reach 100 mm or above, or it has already reached 100 mm and the rainfall may continue. Guide to defense: 1. Personnel should stay in a safe place, and outdoor personnel should take refuge in a safe place immediately; 2. Relevant emergency departments and emergency rescue units are ready to start emergency rescue plans at any time; 3. Schools, kindergartens and other relevant units with students and employees should take special protective measures, and units in dangerous areas should suspend classes or suspend business and immediately move to safe places for temporary refuge; Other rainstorm orange warning signals.

Third, the high temperature warning signal The high temperature warning signal is divided into two levels, which are represented by orange and red respectively. Provincial meteorological authorities in arid areas may formulate high-temperature early warning standards according to actual conditions, and report them to China Meteorological Bureau for approval before implementation.

(1) High temperature orange warning signal Meaning: The maximum temperature will rise above 37℃ within 24 hours. Guide to defense: 1. Try to avoid outdoor activities at high temperature in the afternoon, give guidance to the old, weak, sick and young people for heatstroke prevention and take necessary protective measures; 2, the relevant departments should pay attention to prevent excessive electricity consumption, wires, transformers and other power equipment load is too large and cause a fire; 3.

7. Causes of natural disasters and preventive measures

Meiyu Jianghuai area The cold and warm air masses in Jianghuai area are evenly matched in late spring and early summer, with continuous rainfall-a lot of precipitation; There is "empty plum" weather-drought and precipitation-drainage; There is "empty plum" weather-after the plum rain in the middle and lower reaches of the Yangtze River in July, under the control of a single subtropical high, the weather is very hot and rainy, and the task of drought resistance is arduous. If there is typhoon rain, it may alleviate the drought. Timely forecast the strong tropical cyclone storm formed on the tropical ocean along the southeast coast of typhoon in summer and autumn, make good preparations for typhoon transit, establish and improve the disaster reduction policies and regulations system, and build coastal shelterbelts. Raise public awareness of spring drought disaster. From March to May, the temperature in North China rose rapidly, evaporation was strong, the summer monsoon did not arrive (or was affected by a single cold air), precipitation was less, and it was in the planting and growing season of crops. The air is dry, the soil is short of water, the water level of rivers and lakes drops, and the summer floods in North China and South China are irrigated. The spring breeze from June to August comes late, which affects for a long time and has a high rainfall intensity. The flood disaster drained the low-lying areas and dredged the rivers. Increase the cold of the estuary in the eastern monsoon region. From March to May, the polar continental air mass is strong, and there are cold waves such as strong low temperature and plastic film covering rain and snow in spring. In addition to the Qinghai-Tibet Plateau, the strongest cold air quickly invaded the wind, rain and snow in winter and spring and autumn, and the freezing damage lasted for a long time and covered a wide range. Strengthen the alarm and prepare for the cold. The sandstorm weather in the three northern regions blows in spring and autumn, and the northwest monsoon is the worst in spring. In arid areas, the wind is strong, the atmospheric sediment concentration is high, the visibility is low, and the influence range is wide. Shelterbelt is generally built along the path of cold wave, and returning farmland to forest and grassland. Rainstorms and floods last for a long time in summer and autumn in vast areas except some desert areas in the west, such as fronts, cyclones, tropical cyclones and other precipitation with high intensity and short time, which causes floods. In the southern (and eastern) areas of China, dams, rivers, reservoirs and flood diversion areas will be built in the torrential rain, land management in flood-prone areas will be strengthened, flood forecasting and early warning systems will be established, and emergency evacuation plans and countermeasures will be formulated to realize flood control insurance and other droughts in North China and Northwest China. Long-term lack of precipitation or unusually little precipitation in winter and spring, dry air and lack of water in soil will make outstanding world problems affect economic development and social stability according to local conditions. Rationally adjust the agricultural structure, improve the agricultural ecological environment, select excellent crop varieties in drought-prone areas, develop agricultural water conservancy facilities, build shelter forests and improve farming systems.

8. There are few natural disasters, and there are always eleven paragraphs in the handwritten newspaper. A paragraph or two, the sooner the better.

1. Earthquake: In case of earthquake, take shelter first, find a gap under the table, bend down and lean against the corner, seize the opportunity to escape and stay away from all buildings. 2. Fire: If you are afraid of smoke when you are on fire, cover your nose with a wet towel, and it will catch fire and roll on the ground. If you don't take the elevator down, the balcony will slide down with a rope, and jumping blindly will hurt you. 3. Flood: The flood is fierce and high. Prepare food flashlights and wear warm clothes to avoid danger. 4. Typhoon: When the typhoon comes, listen to the forecast, reinforce the dam to pass through the waterway, repair the gas path, make the temporary building firm and safe, anchor the ship deeply in the harbor, and reduce the signal of travel. Fifth, debris flow: rainstorm, debris flow, dangerous places are downstream, escape from the bottom of the ditch, climb up the mountain quickly, camp in the wild without choosing the ditch, and enter the mountain depending on the climate. Stay away from the poles of the tower and take precautions when it thunders. Close the doors and windows and cut off the power supply to avoid escaping in the lightning fire room. 7. Blizzard: On a blizzard day, people jog without stopping with the wind, and their bodies are unconscious with cold. Never bake with fire, wash blood circulation with ice and snow, and warm up slowly. 8. Tornado: Tornado and strong storm. Once the cellar is attacked, avoid leaving doors and windows indoors and turn off all power and water sources. Don't be careless. Be careful to prevent infection. Isolate, ventilate and disinfect tableware when patients are found. If someone is infected, seek medical attention as soon as possible and go to public places less. X. Chemical prevention: chemicals are dangerous. Don't pick up waste materials to prevent fireworks from burning toxic gases. Call the police to explain the accident point. Don't watch the transportation leakage. People should stay away from the limelight. Human life is more important than mountains, and disaster prevention and avoidance should be done before it happens. Practice your skills often.

9. Knowledge of natural disaster prevention

Prevention and Response to Natural Disasters (1) Throughout the ages, no matter how human society develops, disasters and accidents always occur from time to time, threatening the safety of human life and property.

Although disasters and accidents cannot be completely eliminated and avoided, a large number of practices at home and abroad have proved that disasters and accidents can be prevented, and effective protective measures can reduce the losses caused by disasters and accidents. Do you know how to save yourself effectively in the face of natural disasters? When the rainstorm comes, if our home is in a low-lying place, we can take measures of "small encirclement" according to local conditions, such as building a red brick fence, placing sandbags at the gate and configuring small pumps.

If we live on the ground floor, we should move the electrical sockets and switches at home to a safe place above the ground 1 meter. Once the outdoor water overflows into the house, cut off the power supply in time to prevent electric shock from hurting people.

When threatened by flood, if there is enough time, it is necessary to move to safe places such as hillsides and highlands in an organized way according to the predetermined route; In the case of being caught off guard and surrounded by floods, it is necessary to use boats, rafts, door panels, wooden beds and other items suitable for floating to transfer water as much as possible. If the flood comes too fast to move, climb the roof, tall buildings, big trees and high walls immediately and stop to avoid danger.

But don't swim and escape, let alone climb electrified telephone poles and iron towers, and don't climb the roof of mud houses. At the same time, seek help from the outside world through various channels, get in touch with the local flood control department as soon as possible, tell them our location and danger, and actively seek rescue.

If the flood continues to rise, it is difficult for us to protect ourselves in temporary shelters, so we should make full use of life-saving equipment around us to escape from the water. Find a rope that is strong enough and long enough (you can also use a torn quilt cover instead). First, tie one end of the rope to a firm place in the house, and then take the rope to the nearest fixture (such as a tree, a concrete column, etc.). After winding the rope around the fixture several times, it will go to the next fixture. So repeatedly, gradually move to a higher place.

If you have been involved in the flood, you must try your best to catch fixed or floating things and look for opportunities to escape. Self-help in a typhoon is accompanied by abundant rain, and typhoons always cause all kinds of injuries. Because of its sudden and destructive characteristics, it is one of the most serious natural disasters in the world.

When the typhoon comes, try to stay indoors and try not to go out for a walk, not to mention going to the area where the typhoon passes, swimming or sailing on the beach during the typhoon, not to mention going to the beach to watch the tide. If you have to go out, you should bend down and huddle up. Be sure to put on light waterproof shoes and colorful tight underwear, fasten clothes or tie them with belts to reduce the wind area, and put on a raincoat, rain hat, hat belt or helmet.

When walking, you should walk steadily step by step, and you must never run when the wind is downwind, otherwise you will not be able to stop and even be blown away. Try to grab corners, fences, posts or other solid fixtures to walk; When walking in a street with dense buildings, pay special attention to falling objects or flying objects to avoid injury; When you come to the corner, stop and observe before you go. Walking rashly is likely to be injured by flying objects. When crossing a narrow bridge or a high place, it is best to lie down and crawl, otherwise it will be easily blown down or fall into the water. Call for help in time in case of danger (local disaster prevention telephone, 1 10, 1 19, etc.). ).

In case we are accidentally blown into the water in the typhoon, it is most important to keep calm. When you fall into the water, try to catch the floating wood, furniture and other items around you. Take a deep breath before falling into the water, grit your teeth when sinking, and make us float to the surface with the help of natural buoyancy; When a big wave approaches, you can bend down and dive into the bottom, put your hands in the sand to stabilize your body, and then surface after the big wave; When the waves come, we should straighten up, put our chin forward, make sure our mouths are out of the water, keep our arms stretched forward or our backs flat, and keep our bodies in a surfboard state. After the wave comes out, swim forward while treading water, while observing the movement of the next wave, and then keep kicking with the momentum of the wave, try to float on the wave and follow the wave trend, and try to get close to the shore.

Self-rescue earthquakes rarely occur in earthquakes. Once it happens, houses will collapse, dams will burst and the earth will crack, which will bring serious losses to our lives and property. In order to protect ourselves in the event of an earthquake, we should adopt the following emergency self-help methods: If an earthquake happens suddenly, if we are indoors, we should hide between two load-bearing walls in time, such as the kitchen and bathroom.

You can also hide under solid furniture such as tables and cabinets and in indoor corners, and protect your head with bedding, pillows, cotton-padded clothes, washbasins and other items. Never stay near the window or balcony, and don't try to run out of the building, because it's too late.

Leave the house as soon as possible after the earthquake and move to a safe place. If the house collapses in the earthquake, you should stay under the bed or table and never move. Wait until the earthquake stops before moving out or waiting for rescue.

When an earthquake happens, if we are in a public place, we can't panic and run around. Calm down, observe the surrounding environment, immediately hide in the nearest and safer places, such as desks, cabinets, and under the stage. Never stay in dangerous places such as tall buildings, billboards, narrow alleys, and bridges, let alone run into buildings to avoid danger.

If we are unfortunately buried in the ruins after the earthquake, we must first find ways to remove the objects that are pressed above our abdomen; At the same time, cover your nose and mouth with towels and clothes. Prevent smog from choking people; Try to find food and water and create living conditions. When you hear a sound outside, make full use of all kinds of instruments around you for help, such as hitting each other with hard objects such as metal and stones, or calling for help loudly, but pay attention to saving your physical strength and avoiding premature failure. If you are unfortunately injured, you generally don't need to deal with a small amount of bleeding wounds.

If the wound is bleeding heavily, it can be bandaged with clean gauze, bandage or handkerchief to stop bleeding. Stay indoors in lightning weather and close the doors and windows; When you can't hide in a building with lightning protection facilities in the wild, you should take off your watches, glasses and other metal objects. Never.
