The correct way to prevent floods
Severe floods usually occur in rivers, coastal areas and low-lying areas. If you live in these places, you must be extra careful when there is continuous rainstorm or heavy rainstorm. You should pay attention to the flood warning of the meteorological station, and observe the water level changes of streams and rivers around the house at any time, as well as whether there is any abnormality on the mountain. Especially at night, be very vigilant, be ready for safe transfer at any time, and choose the best route and destination to evacuate.
(2) When receiving the flood forecast, you should prepare enough food, clothes, drinking water, daily necessities and necessary medical supplies, properly arrange household valuables, or bury the inconvenient valuables in the ground or put them in a high place after waterproof binding. Small valuables such as tickets and jewelry can be sewn into clothes to carry with you.
(3) Collect materials suitable for floating, such as wooden pots, wood, large pieces of foam plastic, etc., and process them into life-saving devices for emergencies.
④ Keep the communication equipment that can still be used. Collect flashlights, whistles, mirrors, lighters, colorful clothes and other items that can be used as signals to prepare for rescue.
Preventive measures to prevent flood disasters
China has a vast territory, and some places have some big or small floods almost every year. Severe floods usually occur in river valleys, coastal areas and low-lying areas. During the rainstorm, people in these places must be extra careful to prevent floods. So, what preparations should we make? (1) Listen to the flood warning in rainy season, and learn more about the possible rising height of the water surface and the areas that may be affected.
② In case of flood, there is usually enough warning time. Compared with the flood after the rainstorm, the flood flow is relatively slow. In the face of possible floods, a waterproof wall should be built outside the threshold (if the flood is expected to rise very high, it should also be built outside the bottom window sill). The best material is sandbag, that is, sandbag, plastic woven bag or rice bag, and the flour bag is filled with sand, gravel, soil, cinder and so on. Then there are old carpets, old blankets, old cotton wool, etc. Used to block the gap between doors and windows. (3) When the flood comes, preparing necessary materials can greatly improve the success rate of hedging. ?
Prepare a radio to listen to and understand all kinds of relevant information at any time.
Prepare enough drinking water, canned fruit juice and food with long shelf life, and bind and seal them to prevent mildew and deterioration.
Prepare warm clothes and medicines to treat colds, dysentery and skin infections.
Prepare items that can be used for communication, such as flashlights, candles and lighters. And prepare brightly colored clothes, flags, whistles, etc. In case of accidents.
Fill up the car and make sure it starts at any time.
(4) In the high flood season, we should reserve drinking water, warm clothes and fire fighting equipment, especially in remote mountainous areas, and we must be prepared to save ourselves and collect ropes or sheets for emergencies.
⑤ Learn the skills of making simple rafts at ordinary times, and bind them with anything floating in the water around you, such as beds, wooden beams, boxes, logs, wardrobes, etc.
Expert tip: When the flood comes, prepare life-saving articles. When the flood comes, choose everything that can save lives to escape.
Choose large containers, such as oil drums and water storage tanks. After pouring out the stock solution quickly, re-cover the lid.
Empty beverage bottles, wooden wine barrels or plastic barrels all have a certain floating force and can be tied together for emergency.
Football, basketball and volleyball are all buoyant.
Trees, tables, chairs, benches, boxes and other wooden furniture have buoyancy.
If there is continuous rainstorm and heavy rainstorm, we should be vigilant, stay away from waterways and low-lying areas, and it will be safer to station in highlands. If the water level rises, it will move to a higher area.
Because animals will also hide in high places, both carnivores and weak animals will be safely concentrated, so when the flood comes, the initial food source will not be a problem. But be careful of frightened animals in the water to avoid injury. The water may be polluted, so the drinking water will be tight. Rainwater can be collected, and it is best to boil it before drinking.
How to deal with floods
1. When the flood comes, people who have no time to move should quickly move to nearby hillsides, highlands, buildings, flood shelters and other places, or immediately climb on roofs, tall buildings, trees, high walls and other places for temporary refuge.
2. If the flood continues to rise, it is difficult to protect the temporary shelter, so you should make full use of the prepared life-saving equipment to escape, or find some door panels, tables and chairs, wooden beds and big bubbles. Foam and other floatable materials are tied to rafts to escape.
3. If you have been surrounded by floods, try to get in touch with the flood control department of the local government as soon as possible, report your position and danger, and actively seek rescue.
Note: Never swim to escape, do not climb electrified telephone poles and iron towers, and do not climb the roof of mud houses.
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.
5. When it is found that the high-voltage tower is tilted or the wires are broken and drooping, it must be quickly avoided to prevent direct electric shock or grounding? Step voltage? get an electric shock
6, after the flood, to do a good job of health and epidemic prevention, to prevent the spread of the epidemic.
Self-rescue method in urban flood
What should I do if I encounter a flood in the city? Experts say that I should quickly climb a solid building to avoid danger, and then I should contact the rescue department. At the same time, pay attention to collecting all kinds of floating objects. Wooden pots and barrels are good tools to escape danger. On the one hand, the reason for missing people in the flood is that the flood flow is large and it is hard to prevent. On the other hand, it is also because some people don't understand the water situation and take the risk. So in the flood, we must pay attention to, if you don't know the water situation, you must wait for rescue in a safe zone.
1. Generally, the refuge should be located in the place closest to home, with high terrain, convenient transportation and good sanitary conditions. In cities, they are mostly flat roofs of high-rise buildings, schools, hospitals or solid buildings with higher terrain.
2. Put clothes, quilts and other warm things on high places; Bury valuables that are inconvenient to carry underground or put them on high places after waterproof binding. Tickets, jewelry and other items can be sewn into clothes.
3. Tie a raft, collect floating objects such as wooden pots and blocks, and process them into life-saving equipment for emergency use; It is difficult to find suitable drinking water when the flood comes, so clean drinking water can be stored in water containers such as wooden pots and buckets before the flood comes.
4. Prepare medicines, kindling and other items; Keep all kinds of communication facilities that can still be used, and maintain good communication and transportation links with the outside world.
5. When threatened by flood, if you have enough time, you should go in an organized way according to the scheduled route.
Transfer in hillside, highland and other places; 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.
6. When the flood comes too fast to move, try to use some materials that are not afraid of being washed away by the flood, such as sandbags and stone piles, to block the gap in the threshold of the house, reduce the influx of water, or hide on the roof to avoid water. If the house is not strong enough, make a wooden (bamboo) raft to escape, or climb a tree to take refuge and wait for rescue. Try to bring some food and clothes before you leave home. Don't swim alone. In mountainous areas, if it rains continuously, it is easy to flash floods. In this case, attention should be paid to avoid crossing the river and being swept away by mountain torrents, and to prevent landslides, rolling stones and mudslides. When the high-voltage tower is found to be toppled, the wire sags or breaks, stay away from danger, and do not touch or get close to it to prevent electric shock. Don't haggle over every ounce for the property at home, and don't just focus on the property and forget the safety of life. In order to preserve the property, it is best to close the door when leaving the residence, so that the property can be returned to its original owner after the flood recedes and will not go with the flow.
