Based on years of experience, some experts in flood control and typhoon prevention put forward typhoon prevention schemes for public reference.
Pay attention to the warning before the typhoon comes. The flood control department will issue different warnings in time according to the approach and influence of the typhoon. If the city is affected within 24 hours, a blue or yellow warning will generally be issued.
/kloc-If the whole city is affected within 0/2 hours, an orange warning will be issued. If the city is affected within 6 hours, a red warning will be issued.
Prepare before the typhoon 1, and clean the window sill. Move the flowerpots and sundries placed in the stainless steel frame outside the window or on the balcony indoors, and check whether the awning and the fixed frame of the outdoor unit of the air conditioner are loose.
If the balcony is sealed with aluminum alloy windows or plastic steel windows, it is necessary to check whether the window frame needs reinforcement. 2. Reserve food.
If there are only elderly people at home, and the food market and supermarket are far away from home, you might as well buy more fruits, vegetables, fish and other non-staple foods and store them in the refrigerator for later use. 3. Stop riding a bike.
12 typhoon comes, the wind force on the whole human body is about 100 kg. Even if the wind force is 8, the human body will be greatly impacted.
If you ride a bicycle, moped or motorcycle, the impact may be greater and the front of the car may drift out of control. If a typhoon is likely to strike before going to work that day, don't go to work by bike.
Avoid going out when there is a typhoon. Members of the public should try their best to finish outdoor activities before the typhoon strikes. If they are outdoors or outdoors when the typhoon strikes, they must be very careful. 1, walk against smashing.
When walking, bend over and walk slowly, and try to grasp fixed objects such as railings nearby. If the wind is too strong when crossing the bridge, you must crawl on your back.
On the roads with dense surrounding buildings, flowerpots, glasses, billboards, etc. may suddenly fall, so pay special attention to the height when walking. 2. Drive slowly.
When a typhoon strikes, the wind and rain are often big and small. If the wind and rain become smaller for a period of time, drivers should also keep driving at a low speed and see the road conditions clearly.
Because if there is a sudden strong wind at this time, pedestrians are likely to be involuntarily blown to the front of the car. Slow down before crossing the underpass overpass to see if there is water under the bridge that may cause the vehicle to stall.
3. Avoid the iron tower to avoid the storm, but also pay attention to lightning protection. Don't stay near iron towers, transformers, cranes, metal sheds, iron fences and metal hangers, and don't stay under big trees or near railway tracks. Beware of electric shock after the typhoon leaves. Electric shock accidents often occur when typhoons hit or after typhoons.
After the typhoon, children should be especially careful not to play where the wires fall. 1, the ground wire should be far away from the ground wire. Don't go near it, regardless of whether the pipeline is broken or not, and don't use wet bamboo poles or wet wooden poles to stay.
If the overhead power lines in residential areas fall to the ground, you can put up warning signs around them first, and then call the power hotline for maintenance. 2. If the house leaks water, it must be checked by power failure. Nowadays, many families connect microwave ovens, refrigerators and televisions with drag boards, which are often placed on the floor.
If people who live on the ground floor come home after the typhoon and find water, they must cut off the power first, and then go into the house to clean the mop board. If you find that the wall, faucet or other places are "numb", you should report for repair immediately.
Typhoons bring floods and power outages. How to ensure food safety in power failure or flood after typhoon, people must also evaluate the safety of stored food and drinking water. 1, in case of power failure, try to keep the refrigerator and freezer doors closed to maintain low temperature.
Even if you eat meat, poultry, fish or eggs that are refrigerated or frozen at a safe temperature, you must cook them thoroughly. As for babies, if possible, it is best to eat canned infant formula and breast milk instead of food without water.
3. Typhoons, especially those accompanied by tidal bore or flood, will pollute public water sources. You should always listen to local notices about the safety of drinking water supply.
4. If there is no bottled water and you are not sure whether the tap water is safe, you can purify the tap water according to the following steps: (1) If there is a heat source, boil the water for 1-3 minutes. (2) If the water can't be boiled, add 8 drops of newly bought odorless household bleach solution to each gallon (3.8 liters) of water, fully stir and let it stand for 30 minutes before drinking.
Note: Using bleach solution can't kill parasites. Of course, you can also buy pure water tablets from the local drugstore.
Be careful not to eat any food that may have been exposed to the flood. Any food without waterproof packaging that may have been soaked in flood water should be discarded.
6. Remember to remove wooden incisions, plastic products, baby bottle nipples and pacifiers that have been soaked by floods. As for kitchen utensils, metal pots, ceramics and other utensils can be thoroughly cleaned with soap and hot water, and utensils can be disinfected.

Typhoon safety self-help
1. Don't go swimming or going out to sea after seeing the typhoon warning.
Prepare enough water, candles, flashlights and food.
3. Strengthen outdoor wires and outdoor antennas. , and close the doors and windows.
4. Pay attention to hygiene, safety and epidemic prevention.
5. Try to hide in a solid building, and don't get close to trees, huts or other simple buildings to avoid injury.
6. Don't hide under buildings with billboards or glass curtain walls to avoid being injured by collapsed billboards or falling glass.
7. Walk away from tall buildings and avoid being hurt by falling objects. And pay attention to traffic to prevent traffic accidents.
3. Typhoon warning
Key points of preventing typhoon injury
1, typhoon damage is serious, don't ignore it. The injury rate of people who don't care about typhoon hazards is 17 times that of people who care about typhoon hazards.
2. The key time to prevent typhoon damage is 65438+ 0~6 hours before the typhoon lands, especially 3~4 hours before landing, not when landing. Therefore, all preparations should be completed 12 hours and 1~6 hours before the typhoon lands. Avoid going out and try to stay indoors. People who are not indoors are four times more likely to get hurt than those who stay indoors.
3. The prevention of typhoon injury focuses on men and the elderly, especially those over 70 years old.
4. The main causes of typhoon casualties are house collapse, hard objects and falls. Therefore, people in dangerous houses must be evacuated in time.
5. Reinforce the doors and windows 12 hours before the typhoon, and don't close the doors and windows or repair the house temporarily.
The meaning of typhoon blue warning signal: it may be affected by tropical cyclones within 24 hours, with an average wind force of more than 6 or a gust of more than 7; Or have been affected by tropical cyclones, the average wind force is 6~7, or the gust is 7~8 and may continue.
The yellow warning signal of typhoon means: it may be affected by tropical cyclones within 24 hours, with an average wind force of more than 8 or a gust of more than 9; Or it has been affected by tropical cyclones, with an average wind force of 8~9, or a gust of 9~ 10 and may continue.
The meaning of the orange warning signal of typhoon: it may be affected by tropical cyclones within 12 hours, and the average wind force may reach 10 or above, or the gust 1 1 above; Or have been affected by tropical cyclones, the average wind force 10~ 1 1, or the gust1/kloc-0 ~/2 may continue.
The meaning of typhoon red warning signal: It may or may have been affected by tropical cyclones within 6 hours, and the average wind force may reach or reach 12 or above and may continue.
Typhoons can be prevented. With the rapid development of science and technology, the specific moving direction, landing place and time of the wind can be accurately predicted with modern equipment. As long as we take effective defensive measures, improve the level of scientific detection and early warning, do a good job in prevention and rescue, seek advantages and avoid disadvantages, and minimize the degree of disasters. Before the typhoon comes, we should pay attention to watching the typhoon disaster weather warning information released by meteorological stations at all levels. In order to ensure the safety of primary and secondary school students, we should make corresponding preparations in advance, minimize going out, stay away from low-lying areas and dangerous areas such as the seaside, and stay away from dangerous facilities or articles such as trees and billboards. Move schools, students and residents in dangerous areas to safe areas in advance.
4. What are the escape and self-help methods when encountering a typhoon?
(1) During the typhoon, try to stay at home and don't go out for a walk.
If you have to go out, you'd better put on colorful, tight-fitting clothes and lightweight waterproof shoes, fasten your clothes or tie them with belts, bend down and shrink your body into a ball to reduce the wind area. In addition, wear a raincoat, a rain hat and a hat belt.
(2) When walking, walk slowly and smoothly. If it is downwind, try to hold on to fences, posts or other solid fixtures, and never run away, otherwise it will not stop or even be blown away by the wind. When you come to the corner, stop and observe before you go. Walking rashly is likely to be injured by flying objects. When crossing narrow bridges or high places, it is best to crawl on your back, otherwise it will be easily blown down or fall into the water; Pay special attention to flying objects or falling objects when passing through streets with dense buildings to avoid injury; If there is heavy rain during the typhoon, you should be careful of the water on the road. Children and the elderly should not walk in the water.
If you are accidentally blown into the sea, try to swim back to the shore. Even if you can't swim back, try your best to find floating objects for rescue. (3) Don't stay near glass doors and windows; Check and fasten objects that are easily blown down by the wind, such as windows; Close doors and windows to avoid being blown open by strong winds; If the glass is found to be loose or broken, please stick adhesive tape on the glass to prevent the debris from splashing around after being blown by the wind.
5. How to save yourself in a typhoon
How to avoid risks in case of typhoon (1) and typhoon prevention measures (1). According to the possible impacts of typhoons, meteorological stations issue forecasts to the public in three forms: "news", "alarm" and "emergency alarm". At the same time, according to the possible impact of typhoons, the blue, yellow, orange and red typhoon warning signals will be released to the society from light to heavy.
The public should pay close attention to the media reports about typhoons and take preventive measures in time. 2. Strong wind may blow down buildings and high-altitude facilities, causing casualties.
People living in all kinds of dilapidated houses, factories and sheds should be moved to safety in time before the typhoon comes, and should not take shelter from the wind and rain near temporary buildings (such as fences), billboards and iron towers. Vehicles should try to avoid driving in areas affected by strong winds; 3. Strong winds will blow off high-altitude objects, and it is necessary to move flowerpots and hangers on roofs, windows and balconies in time; Before the typhoon comes, it is best not to go out to avoid being smashed, crushed and electrified. Check the safety of doors and windows, outdoor air conditioners, cages and solar water heaters, and reinforce them in time; 4. Prepare flashlights, food and drinking water in time, check the circuit, and pay attention to kindling and gas to prevent fire; 5. While doing the above-mentioned windproof work, we should do a good job in preventing heavy rain.
6, before the typhoon, should be ready to flashlight, radio, food, drinking water and commonly used drugs, in case of emergency. 7, close the doors and windows, check whether the doors and windows are firm; Take down the hanging things; Check whether the circuit, fire fighting, gas and other facilities are safe.
8. Move animals, plants and other items raised outdoors indoors, especially the sundries on the roof; Things that are easily blown by the wind outdoors should be reinforced. 9. Don't travel to the area where the typhoon passes, and don't go swimming or sailing on the beach during the typhoon.
10, people living in low-lying areas and dangerous houses should be transferred to safe houses in time. 1 1. Clean the drainage pipeline in time to keep the drainage unblocked.
12, relevant departments should strengthen outdoor billboards; Temporary buildings should be reinforced at the construction site, and construction equipment and tools should be arranged and stacked; Garden departments should strengthen street trees in urban areas. 13. In case of danger, please call the disaster prevention telephone of the local government for help.
14. To return to Hong Kong and anchor in time, the crew on board must go ashore to take shelter from the wind. (2) Matters needing attention during typhoon 1. Try not to go out for a walk during the typhoon. If you have to go out, you should bend down and huddle up. Be sure to wear light waterproof shoes and colorful tight underwear, fasten your clothes or tie them tightly with a belt to reduce the wind area, and wear a raincoat, rain hat, hat belt or helmet.
When walking, walk slowly and steadily, and never run with the wind, otherwise you will not be able to stop or 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. If there is heavy rain during the typhoon, pay attention to the depth of the road. /kloc-children under 0/0 are not allowed to walk in the water. Take children across the beach in cans or buckets.
If you are accidentally blown into the sea, try to swim back to the shore. If you can't swim back, you should try your best to find floating objects for rescue. 2. When traveling, if you can leave the typhoon-passing area after hearing the typhoon forecast issued by the Meteorological Observatory, leave as soon as possible. Otherwise, they should store enough food and drinking water, such as canned food and biscuits, and buy enough lighting supplies, such as candles and flashlights.
Because typhoons are the most destructive when passing through islands and coasts, they should be as far away from the ocean as possible; When traveling in coastal and low-lying areas, you should try to take refuge in solid hotels and typhoon shelters far away from the coast. 3. When a ship is attacked by a typhoon during the voyage, it should take the initiative to take emergency measures and contact the relevant departments on the shore in time to understand the relative position of the ship and the typhoon.
It is also necessary to mobilize the crew as soon as possible to drive the ship into the safe haven and seal the cabin. In the case of sailing, the sail should be put down as soon as possible; If you are traveling by car, you should drive to the underground parking lot or shelter from the rain; If you live in a tent, you should pick it up and take shelter from the wind in a solid house; If you are already in a solid house, close the window carefully and stick a herringbone pattern on the window glass with tape to prevent the window glass from breaking. 4. Be sure to stay indoors or in the original hiding place shortly after the strong typhoon.
Because the typhoon's "eye of the wind" passes overhead, the ground will be calm for a while, but don't think that the storm has passed. Usually this calm lasts less than 1 hour, and the wind will sweep again from the opposite direction. If you hide outdoors, you should move to the opposite side of the original shelter.
(3) Environmental sanitation and disinfection of food and water should be paid attention to after the disaster. During the power outage and flood after hurricane, necessary measures should be taken to ensure the health and safety of personnel. After the storm, people can follow the following suggestions given by FDA to protect themselves and their families.
● During the power failure or flood after hurricane, FDA believes that the biggest food safety challenge for consumers will be to keep the food temperature at 40 degrees Fahrenheit (44 degrees Celsius) or below, and to keep the frozen food temperature at 0 degrees Fahrenheit (minus 18 degrees Celsius) or below. Perishable foods, such as meat, poultry, seafood, milk and eggs, may cause diseases even if they are completely cooked if they are improperly refrigerated or frozen.
●FDA believes that consumers should also evaluate the safety of stored food and drinking water in case of flood. Ten skills of typhoon avoidance and disaster prevention.
1 food mineral water may sound exaggerated, but judging from the typhoon season in previous years, it is completely correct to prepare some dry food and drinking water. Because of the typhoon, it is likely that there will be power cuts and water cuts. If your home is located in a low-lying area, you may be trapped for a day or two. At this time, these things come in handy.
Although I don't know how powerful the new typhoon is, it's always right to make preparations early. No.
Small flashlight lighting can be of great use. In addition to food, it is best to prepare some energy-saving lamps such as flashlights, candles and electricity storage at home, because in case of power failure or water supply at home.
6. Typhoon warning
The typhoon is coming, how to prevent it?
1, be alert to typhoon trends, pay attention to listening to and watching media reports, or learn about the latest situation of typhoons through meteorological consultation telephones and meteorological websites.
2. When the typhoon comes, close the doors and windows to prevent it from raining, and remove the flowerpots on the windowsill or balcony to prevent them from falling.
When the typhoon comes, it is easy for some large billboards to fall, trees to be blown down and telephone poles to fall to the ground. It's best to avoid going out when the typhoon comes.
People who have to go out to work must choose a safe zone when avoiding the wind and rain, and be careful to "fly" to cause trouble. In the wild, we should pay attention to the dangers such as road collapse and broken trees.
5. Typhoon weather will cause water accumulation on the road surface and ground sliding, which will affect driving or cars and cause accidents. Therefore, drivers must slow down when driving, and friends who ride bicycles had better choose to walk or take the bus in bad weather.
6. If you find that the high-voltage tower is toppled, the wires are drooping or broken, don't approach it, let alone touch it with your hands, because it will easily lead to electric shock accidents.
Typhoon prevention:
1. After the typhoon warning is issued by the Meteorological Observatory, don't go to the area where the typhoon passes or swim on the beach, let alone go sailing; People who go out should go home as soon as possible.
2. The residents living in the building should close the windows and take away the things on the balcony (flowerpots, clothes hangers, etc.). ); Reinforce outdoor objects that are easy to blow.
The public should pay attention to the typhoon news broadcast and published by the media and take preventive measures.
4. Clean the drainage pipes to keep the drainage unblocked.
5. Ships should enter the safe haven in time.
6. When the typhoon strikes, don't go near the window to avoid being hurt by the broken window glass.
7. What is a typhoon? A little common sense of typhoon.
Typhoon is a classification of tropical cyclones in Asia-Pacific countries or regions north of the equator and west of international date line.
In meteorology, according to the definition of the World Meteorological Organization, the sustained wind speed of tropical cyclone center reaches 12 (that is, more than 64 knots, more than 32.7 meters per second, or more than 1 18 kilometers per hour), which is called hurricane or other local synonyms. The synonym used in the Pacific Northwest is typhoon.
Both the World Meteorological Organization and the Japan Meteorological Agency regard this as the highest level of tropical cyclone, but some meteorological departments will set a higher level according to their needs, such as the strong typhoon and super typhoon at the China Central Meteorological Observatory and the Hong Kong Observatory, the strong typhoon in central weather bureau, Taiwan Province Province, and the super typhoon at the United States Typhoon Warning Center. [ 1]。
8. What are the self-help methods when encountering a typhoon?
Typhoon is a frequent disaster in China's coastal areas, especially in Guangdong, Fujian, Zhejiang, Jiangsu and Shanghai, and its occurrence has obvious seasonality.
When the typhoon comes, there are not only powerful storms, but also heavy rains, which can reach more than 1000 square kilometers. However, typhoons are regular, and even the annual travel routes are similar, so when traveling, you must listen to the weather forecast and try to avoid the typhoon travel routes.
(1) Pay attention to the weather forecast. Pay more attention to media reports, make weather calls before going out or learn the latest situation of typhoons through weather websites, and adjust travel time.
(2) Prepare food and mineral water. Affected by the typhoon, people's homes are likely to encounter power outages and water cuts. It is completely correct to prepare some instant noodles, biscuits and other dry food and drinking water. If they are located in low-lying areas, they may be trapped for a day or two. At this time, these things can come in handy.
(3) Prepare lighting facilities. It is best to prepare some flashlights, candles or energy-saving lamps for storing electricity at home. In case of power failure or water flooding at home, it can solve the problems of lighting and night travel, and it is best to have spare dry batteries at hand.
(4) Check for falling objects. Typhoon, broken branches, billboards on the roof and flowerpots on the balcony can't stand the strong wind falling from the sky.
Before the typhoon comes, everyone should clean up the flower pot hangers in their balcony windows and check the corridor windows. If it is broken, it should be repaired as soon as possible to avoid falling and hurting people when the wind blows. (5) Dredge sewer pipes to prevent water from entering.
In low-lying residential areas, the troubles and dangers caused by stagnant water can still be avoided. Before the rainstorm comes, check your drainage pipe first, and if possible, you'd better dredge it again.
Especially residents living on the first floor should put some electrical appliances, articles, clothes, shoes and so on. Those who are afraid of water should be as high as possible. In case water enters the room, the loss will not be too great. (6) Unplug the power plug before the rainstorm, and quickly cut off the power supply of various electrical appliances to prevent lightning strikes.
Do not use wireless tools such as radio and mobile phone in thunderstorm weather. Radio waves can cause lightning strikes, which is very dangerous. (7) Don't open the windward window.
When the typhoon comes, doors and windows should be locked, especially glass doors and windows and aluminum alloy doors and windows. If the glass is loose or broken, please stick adhesive tape on the glass to prevent the fragments from being blown away.
Don't stay near glass doors and windows. Never open the windward window, lest strong airflow enter and blow down the house.
(8) Don't live in a shabby house. When the typhoon comes, don't take shelter from the wind and rain in dangerous old houses, sheds, temporary buildings, scaffolding, telephone poles, trees, billboards, iron towers and other places that are easy to cause casualties.
If you live in a dangerous house or a house with poor wind resistance, it is best to take refuge in relatives and friends. To obey the arrangement of the local * * * department, if it is necessary to evacuate, it must be evacuated immediately to ensure personal safety.
(9) Take care of the elderly and children at home. Old people and children try not to go out when the typhoon strikes.
If the old man or child is alone at home, be sure to remind him not to open the closed doors and windows casually, and don't go near the window to avoid being hurt by the broken window glass blown by the strong wind. When the typhoon comes, turn off household appliances.
(10) Mountain residents should pay attention to landslides and mudslides. Strong winds and heavy rains easily lead to geological disasters such as landslides, mudslides and land subsidence, resulting in casualties. Once you find signs of geological disasters such as landslides and mudslides, don't hesitate to evacuate the dangerous area as soon as possible and report to the relevant departments in time so that the surrounding residents can evacuate in time.
(1 1) If it is in a dangerous dike, it should be moved to a safe place. Coastal fishing boats should return to Hong Kong for shelter from the wind. Typhoon will cause storm surge, easily damage river dikes, culverts, docks, revetments and other facilities, and may even directly wash away nearby people, causing casualties.
Therefore, before the arrival of the typhoon, people engaged in aquaculture outside the pond and people in dangerous dikes and ponds in coastal areas should be transferred to safety in time. (12) If the safety signal is not removed, please don't be careless.
When the typhoon signal is lifted, you can only return after the evacuation area is declared safe, and you must abide by the regulations and do not set foot in dangerous and unknown areas. Don't use gas, tap water, wires, etc. Feel free to know whether it is safe or not, and be ready to ask the relevant departments for help in case of danger.
(13) Be careful of falling objects when going out. During the storm, it is best to avoid going out and stay away from windward doors and windows.
If you must go out, try to stay away from the seaside. When the wind is strong, bend down as much as possible and pay attention to fences, street trees, billboards and other falling objects on both sides of the road. When passing through tall buildings, pay attention to falling objects such as balcony flowerpots, and stay away from dangerous places such as broken poles, road surface collapse and fallen trees. Be careful when riding a bike with rain gear.
Many citizens go out to ride bicycles. When the typhoon comes, rain gear such as ponchos and umbrellas are naturally essential. However, riding a bike with rain gear is also very particular.
Some young people are good at cycling and like to hold the handlebar in one hand and the umbrella in the other. This practice not only violates the traffic rules, but also hurts the human body in the wind and rain, which is not worth it.
9. How to save yourself when a typhoon comes?
① Pay close attention to the media reports on typhoons and take preventive measures in time.
(2) Flashlights, radios, food, drinking water and common medicines should be prepared for emergency use. (3) Close the doors and windows and check whether the doors and windows are firm; Take down the hanging things; Check whether the circuit, fire, gas and other facilities are safe.
④ Move outdoor animals, plants and other items indoors, especially the sundries on the roof; Things that are easily blown by the wind outdoors should be reinforced. ⑤ Don't travel to the area where the typhoon passes, and don't go swimming or sailing on the beach during the typhoon.
6 people living in low-lying areas and dangerous houses should be transferred to safe houses in time. ⑦ Clean the drainage pipes in time to keep the drainage unblocked.
