Tips on preventing meteorological disasters

1. Knowledge of disaster prevention and reduction

Original publisher: XX demon

To prevent and reduce disasters, we must protect the lives of small intellectuals and remember ten rules. Once a disaster occurs, it should be applied in time. 1. Earthquake: In case of earthquake, take shelter first, find a gap under the desk, bend down against the corner, seize the opportunity to escape, and stay away from all buildings. Aftershocks crouch in the open space. 2, fire: fire, fear of smoke, nose and mouth covered with a wet towel, body fire rolling, do not take the elevator down, balcony sliding rope, blindly jumping off the building will be injured. 3. Flood: The flood is fierce, the height is high, the earth roof can't stay, the bed and table are tied with rafts, the trees can be tied with lifeline, food flashlights are prepared, and warm clothes are worn to avoid danger. 4. Typhoon: When the typhoon comes, listen to the forecast, strengthen the dam and waterway, repair the gas path, make the temporary building strong and firm, and the ship will anchor deeply when entering the port, reducing the journey. 5. Debris flow: It rains heavily, and the dangerous place is downstream. Escape from the bottom of the ditch and climb up the hill quickly. You don't choose ditches for camping in the wild, but you must look at the climate when you enter the mountains. 6. Thunder and lightning: In rainy days, thunder and lightning are mixed. Don't stand under the tree to avoid the rain. The poles of the tower should be far away. When it thunders, it is also necessary to prevent problems at home. Close the doors and windows to cut off the power supply and avoid the room where the lightning is on fire. 7. Blizzard: On a blizzard day, people jog, don't stop with their backs to 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, strong storm, once in the cellar, avoid leaving doors and windows indoors, turn off all power and water sources, and lie outdoors in low-lying areas, which makes the car unreliable. 9. Epidemic situation: Be careful about the epidemic situation, don't be careless and prevent infection. When patients are found, they should be isolated, ventilated and disinfected. As soon as they enter the infected place, they should seek medical treatment and seldom go to public places. 10, chemical protection: chemicals are dangerous, so don't pick up waste materials to prevent fireworks from burning toxic gases, call the police to explain the accident point, don't look at the transportation leakage, and people should stay away from the limelight. Human life is more important than mountains. Take precautions, nip in the bud. Master skills and practice frequently. Best wishes.

2. What is the common sense of disaster prevention?

1. When there is a fire in public places, don't panic and run blindly. If the fire is small, take part in fighting and call 1 19 to call the police quickly. If the fire is out of control, escape in an orderly manner according to the evacuation signs, and never take the elevator.

2. When passing through the thick smoke, cover your nose and mouth with a wet towel, try to keep your body close to the ground and wall, bend over or crawl forward. If the clothes catch fire, soak them in water, take a shower, lie down and roll, don't run, don't stand upright. Close the door behind you when you escape to prevent smoke from entering. When you escape, don't push each other or jump off a building in a hurry. If you can't escape, you should retreat to a safe area such as balcony or roof, and send a distress signal to wait for rescue.

3. When a high-rise building escapes from a fire, if the smoke from the lower stairs is rolling or blocked by fire, don't escape by force. It's safer to escape upward. You can wait for rescue on balconies, roofs and other places. Don't get under the bed, in the closet or in the attic to avoid flames or smoke. If you live near the roof, you can go directly to the roof platform and send out a distress signal.

When the flood comes, you should choose all life-saving items to escape. First, select large containers, such as oil drums, water storage barrels, etc., quickly pour out the stock solution, and then re-cover and seal the lid. Empty beverage bottles, wooden wine barrels or plastic barrels all have certain buoyancy and can be tied together for emergency. Football, basketball and volleyball have good buoyancy. Trees, tables, chairs, cabinets and other wooden furniture have buoyancy.

In case of falling into the water, hold your breath and hold your nose to avoid choking, and try to stand up. If the water is too deep, you can't stand up and swim to the shore quickly. Step on the water to help you swim and catch anything floating around. Don't panic if you can't swim. You can act in the following two ways: first, face up, head back, hands down on the water, hands on the water, let your mouth out of the water, and inhale hard immediately after exhaling; The second is to quickly observe whether there are fixed objects exposed to water around and move closer to them.

6. Take off your shoes in time when you fall into the water, reduce resistance, stick your head out of the water and adjust your breathing. Don't struggle unnecessarily when the waves are high and your body is floating, try to save your strength. Avoid heavy objects that may endanger your health, such as whirlpools and stones entrained in water. Never climb a telephone pole to avoid electric shock.

7. If the car falls into the water, it must escape before the water reaches the window, while the car is still floating on the water. When the car sinks into the water, roll up the window and turn on all the lights as a distress signal. If the door won't open, make sure the people in the car are above the water. When the water reaches the chin position, the water pressure outside the car can be lighter. At this time, open the door and take a deep breath to swim to the surface. If the door still won't open, try to break the glass and climb out. When escaping, passengers can be involved in each other, so that the door will not be closed and people can be prevented from being washed away.

3. Knowledge of natural disaster prevention

1, lightning disaster and its prevention

(1) Stay indoors and close the doors and windows in lightning weather; 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) The lighting of classrooms, cabinets in laboratories and bookshelves in libraries 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 its prevention.

(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) threatened by flood, if there is enough time, it should be moved to hillside, highland and other places 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.

4. Who knows some first aid knowledge of natural disasters?

Strategic measures 1: Make plans and be ready at all times. Through the formulation and drills of national, provincial, municipal, district, enterprises and institutions, communities, schools and other emergency plans. Form an orderly and prepared disaster prevention and mitigation situation.

The emergency plan shall include the emergency organization system and responsibilities of natural disasters, forecasting and early warning, information reporting, emergency response, emergency disposal, emergency support, investigation and evaluation, etc. And form a set of work operation mechanism including before, during and after. We should not put the plan on the shelf, but let the masses and disaster managers master the plan skillfully through training and plan drills, and constantly improve the plan in practice.

Be prepared for danger in times of peace, and give priority to prevention. It is necessary to enhance the sense of hardship, persevere and prevent problems before they happen.

Adhere to the combination of prevention and emergency, and the combination of normality and abnormality. * * * Communities should be encouraged to formulate emergency preparedness plans, carry out disaster relief drills, equip with special communication equipment, replace common communication methods in case of emergency, and ensure necessary emergency materials and facilities.

Actively prepare for emergencies in terms of equipment, technology and personnel. Strategic Measure 2: People-oriented, disaster avoidance and mitigation are people-oriented, and ensuring the safety of public life and property is the primary task of disaster prevention and mitigation, so as to minimize the casualties caused by natural disasters and the harm to social and economic development.

In the face of natural disasters, scientific defense, from early blind disaster resistance to active disaster avoidance in recent years, embodies the Scientific Outlook on Development of disaster prevention and mitigation. Strategic measure 3: Monitoring and early warning, relying on science and technology to adhere to the basic principle of "prevention first" in disaster prevention and mitigation, putting disaster monitoring, forecasting and early warning in a very prominent position, and attaching great importance to and doing a good job in publishing early warning information for the whole society, including the socially disadvantaged groups.

Meteorological disaster is a sudden public event with long warning time and high forecasting accuracy. Strengthening the short-term and imminent forecast of disastrous weather, strengthening the production of early warning signals of sudden meteorological disasters and strengthening the release of meteorological early warning information are important scientific and technological guarantees for improving the level of disaster prevention and mitigation. We should rely on science and technology to improve the comprehensive quality of disaster prevention and reduction.

By strengthening scientific research and technological development in the field of disaster prevention and mitigation, adopting and popularizing advanced monitoring, forecasting, early warning, prevention and emergency treatment technologies and facilities, giving full play to the role of experts and professionals, and improving the scientific and technological level of responding to natural disasters. The practice of defending against typhoon in 2005 fully embodies the important role of modern meteorological technology in defending against Taiwan and Taiwan.

Modern detection methods such as new generation weather radar, automatic weather station, mobile weather station and meteorological satellite have improved the ability to monitor the latest trends of typhoons in real time; Numerical forecast products provide a reference for accurately forecasting the future path of typhoons, which makes forecasters more confident and confident in forecasting severe weather such as typhoons, and provides a scientific basis for accurate and advanced forecasting; Key forecasters play an important role in typhoon forecasting service. Strategic measure four: awareness of disaster prevention, and popularizing the public is the main body of disaster prevention.

To strengthen the sense of hardship, nip in the bud, and prevent and reduce disasters, it is necessary for the general public to widely enhance their awareness of disaster prevention and understand and master the knowledge of disaster avoidance. When natural disasters occur, ordinary people can know how to deal with the disaster, how to protect themselves and help others.

* * * Social organizations shall organize and publicize disaster knowledge and train disaster professionals or volunteers. Relevant departments widely publicize the common sense of disaster reduction through books, newspapers, audio-visual products and electronic publications, radio, television and the Internet, so as to enhance the public's sense of urgency, social responsibility and self-help and mutual assistance.

Through the action of "disaster prevention (reduction) into communities, campuses, enterprises and villages", the grass-roots community residents, the majority of primary and secondary school students, enterprise employees, the vast rural areas, especially farmers in remote areas and socially disadvantaged groups will enhance their awareness of disaster prevention and reduction, master the basic skills of disaster avoidance, self-help and mutual rescue, and achieve the goal of disaster reduction. Disaster prevention and mitigation needs to start with dolls and incorporate disaster and disaster emergency knowledge into the teaching content of primary and secondary schools.

Relevant departments should prepare brochures and publicity materials for natural disaster prevention, widely publicize and popularize disaster knowledge, emergency management knowledge, disaster prevention and mitigation knowledge, and improve grassroots people's ability to participate in emergency management and self-help. The public should fully understand the important role of disaster early warning information, understand the meaning of all kinds of early warning information, and take active and effective countermeasures according to different early warning information and different early warning levels when receiving disaster early warning information.

It is necessary to establish a wide and smooth channel for early warning information release. Early warning information is released through radio, telephone, short message, block display screen and Internet, and important early warning information can be immediately inserted in TV programs.

Relevant departments can ensure that disaster warning information reaches effective users within effective time, so that they have the opportunity to take effective defensive measures to reduce casualties and property losses. In recent years, in the major meteorological early warning information service, meteorological departments presented meteorological information to relevant departments of * * * for decision-making, and at the same time broadcast meteorological early warning on TV, and released meteorological early warning information to users by using mobile phone short messages, which made grassroots cadres and masses know about the early warning situation, and solved the "last mile" problem of meteorological products from meteorological bureau to ordinary users, and achieved good results.

Strategic measure 5: Emergency mechanism, rapid response * * *, relevant departments need to establish an emergency management mechanism with "unified command, sensitive response, complete functions, orderly coordination and efficient operation". "Rapid response and coordinated response" is the core of emergency mechanism.

Disaster prevention and mitigation involves all aspects, and requires the organization and leadership of * * * and the positive response of all departments. In the emergency management of meteorological disasters, meteorological departments have strengthened horizontal linkage and close cooperation with news, water conservancy, civil affairs, safety supervision, ocean, agriculture, forestry, environment and other departments, established an emergency linkage mechanism, and incorporated meteorological work into public service systems at all levels.

It is necessary to strengthen the construction of emergency teams based on territorial management, establish a linkage and coordination system, fully mobilize and give play to the role of towns, communities, enterprises and institutions, social organizations and volunteer teams, and rely on public forces to form a standardized and efficient disaster management workflow. Strategic measure 6: Classified disaster prevention, aiming at the offline.

5. Knowledge about natural disaster prevention ~

First, the typhoon warning signal is divided into four levels according to the approaching time and intensity, which are represented by blue, yellow, orange and red respectively.

(1) typhoon blue warning signal meaning: it may be affected by tropical depression within 24 hours, and the average wind force may reach 6 or above or gust 7 or above; Or it has been affected by the tropical depression, with an average wind force of 6-7, or a gust of 7-8 and may continue.

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.

(1) Cold wave blue warning signal meaning: within 24 hours, the minimum temperature drops by more than 8℃, the minimum temperature is less than or equal to 4℃, the average wind force reaches more than 6, or the gust is more than 7; Or has dropped to above 8℃.

6. Safety measures to prevent natural disasters

China is one of the countries with the most serious natural disasters in the world, because of its frequent occurrence, wide distribution and huge losses.

The facts observed in the 20th century show the frequency and intensity of extreme weather and climate events (El Nino, drought, flood, thunderstorm, hail, storm, high temperature weather and sandstorm, etc.). ) caused by the obvious increase in climate change, which directly endangers the development of China's national economy. According to statistics, the affected area of farmland in China is 34 million hectares (more than 500 million mu) every year due to various weather and climate disasters, and the population affected by major disasters such as drought, rainstorm, flood and tropical storm is about 600 million. The average annual economic loss caused by weather and climate disasters accounts for about 3%-6% of GDP.

With the rapid economic growth in China, the absolute value of losses caused by weather and climate disasters is increasing. Considering the secondary disasters such as ecology, environment, geology, society, humanities and economy caused by weather and climate disasters, the economic losses are serious.

The World Meteorological Organization has designated this year's World Meteorological Day as "preventing and mitigating natural disasters", which is of great practical significance to China. In the long-term practice of living in harmony with nature, people from all walks of life engaged in disaster prevention and mitigation research, business and management have formed many effective disaster prevention and mitigation measures.

Strategic measures 1: Make plans and be ready at all times. Through the formulation and drills of national, provincial, municipal, district, enterprises and institutions, communities, schools and other emergency plans. Form an orderly and prepared disaster prevention and mitigation situation. The emergency plan shall include the emergency organization system and responsibilities of natural disasters, forecasting and early warning, information reporting, emergency response, emergency disposal, emergency support, investigation and evaluation, etc. And form a set of work operation mechanism including before, during and after.

We should not put the plan on the shelf, but let the masses and disaster managers master the plan skillfully through training and plan drills, and constantly improve the plan in practice. Be prepared for danger in times of peace, and give priority to prevention.

It is necessary to enhance the sense of hardship, persevere and prevent problems before they happen. Adhere to the combination of prevention and emergency, and the combination of normality and abnormality.

In recent years, meteorological departments have submitted meteorological letters for decision-making to relevant departments in major meteorological early warning information services.

7. Disaster prevention and mitigation is about 50 words.

Disaster prevention and mitigation, defending homeland.

Disaster is the natural enemy of human beings, which not only causes huge property losses, but also takes the lives of tens of thousands of compatriots. Drought is one of the major natural disasters. Even today when science and technology are so advanced, their disastrous consequences still abound. It is particularly noteworthy that with the development of human economy and population expansion, the shortage of water resources is becoming more and more serious, which directly leads to the expansion of drought area and the aggravation of drought. The drought trend has become a global concern.

In fact, drought is directly related to the systematic changes related to human activities, such as plant system distribution, temperature equilibrium distribution, atmospheric circulation state change, chemical element distribution change and so on. Soil erosion, destruction of afforestation, lack of water conservancy projects or fragile water conservancy infrastructure do not conserve water, which does not conform to the laws of flood and drought. Water conservation in flood and water diversion in drought conform to the laws of nature and promote the dynamic balance of water resources, making the disaster situation more and more serious.

From the autumn of 2009 to the beginning of 20 10, southwest China suffered from severe drought. Especially in Yunnan, the worst drought in autumn, winter and spring has occurred since meteorological records, and the recurrence period of comprehensive meteorological drought in the province is once every 80 years; The continuous drought in autumn and winter in Guizhou is generally a serious drought once in 80 years, and the drought in the central, western or southern parts reaches once in a hundred years. At present, Yunnan Province, most of Guizhou Province and some parts of Guangxi have been suffering from drought for more than five months, and the losses are very serious. As of March 23rd, the drought has affected five provinces (regions) in Guangxi, Chongqing, Sichuan, Guizhou and Yunnan, with 61306 million people affected, 0/807.110 million people with difficulty in drinking water, and 0/...

Seeing these amazing data, I think everyone can't help but be shocked. As a member of our homeland, we have the responsibility to protect the earth's homeland and slow down the drought through various actions. From the point of view of water conservancy project construction and drought relief, we really can't just focus on the big ones and put the small ones aside, but we should give consideration to them. We should pay attention to big problems and small problems. Because the big problems are mainly key projects, and key projects are key control problems, but the small ones are very important for solving domestic water consumption and producing some necessary supplementary water sources. For the people, five small projects, that is, small ponds, small water cellars, small wells and so on, are very important to thousands of people.

The key is to increase investment, to increase investment, and now our investment in this area is far from enough, because there are too many historical debts, drought resistance is a comprehensive concept, and it is far from enough to rely on a little investment from * * *, and all aspects of society should be mobilized. We should not only replenish water resources, but also save water resources, publicize the necessary recovery and indiscriminate use of water, and let most people join in it. This can not only alleviate the drought, but also save a lot of water resources. Over time, the drought will definitely leave us gradually.

In disasters, there are some man-made disasters besides natural disasters. Such as gas poisoning, fire and explosion. Among them, fire is the most common. People can't live without firing, but if they use it improperly or manage it badly, it will easily lead to a fire. Therefore, we should pay attention to the fire safety around us in any place at ordinary times to avoid fire.

Now it will also pose a serious threat to the survival of mankind, but as long as we use resources correctly, some disasters will be far away from us.
