Qingyang, Gansu suffered the biggest flood since 1956! What should people pay attention to after the flood?

Heavy rainfall will not only bring floods, mudslides, landslides and other disasters, but also pollute water sources and cause infectious diseases. Therefore, in the flood season, in addition to paying close attention to the correct preventive measures when rain and strong convective weather occur, we should also pay attention to the secondary disasters that are prone to occur after the flood.

Flood refers to the phenomenon that low-lying areas are submerged by rainstorm, rainstorm and continuous rainfall. Floods can be divided into river floods, lake floods and storm floods. Among them, river floods can be divided into rainstorm floods, mountain torrents, snowmelt floods, ice floods and dam-break floods according to their causes. The most influential and common flood is river flood. Flood is obviously seasonal, regional and repetitive. At the same time, flood disasters are very destructive and universal. Flood disaster not only harms society, but also seriously harms adjacent river basins, causing changes in water system.

If the house is flooded and the walls are wet, some power sockets and switches are easily corroded after being soaked in flood water, leading to the danger of leakage and short circuit. So the flooded house must be hung for a few days before using electricity. Before power transmission, it is best to test the line insulation by relevant professionals, and power transmission can only be carried out after passing the test. After being wet for a long time or even soaked in water, the gas pipeline or interface will be corroded and easily leaked, causing explosion or fire. Therefore, before using gas, it must be inspected by the gas supply department before it can be used.

After household appliances are wet or flooded, water vapor adheres to the circuit board or motor, which is easy to corrode the circuit, reduce the service life of household appliances, and increase the hidden dangers of leakage and short circuit. Before use, it is recommended to use a hair dryer to dry household appliances that get wet and get water. Warm air currents take away moisture more easily.

Ms. Jia, a farmer from Banqiao, Heshui County, said that the watermelons planted on 5 mu of land at home will be ripe in a few days. I didn't expect it to be washed away by the flood this time, and I felt particularly distressed. "At present, the flood has receded, but the road at home is bumpy and very difficult to walk." Ms. Jia said.

According to CCTV news reports, some mass caves in Qingyang City were flooded, the courtyard walls collapsed, crops were destroyed, and 129 households with 570 people were evacuated urgently. Some villages and towns in Qingcheng County have lost their mobile and telecommunications networks, power grids and roads. The local emergency, public security and transportation departments have urgently repaired. At present, some roads have been rushed through, and power and communication have been restored.

After the flood, we should actively clean up the surrounding environment, so that the environment will be cleaned up wherever the water retreats, and the disinfection and insecticidal work will be done. Garbage and animal carcasses will be concentrated and composted at high temperature. Sludge should be removed from flooded houses and equipment, and indoor floors, walls and furniture should also be cleaned and disinfected.

Insecticide should be sprayed intensively on flies and cockroaches, and at the same time, mosquito prevention, mosquito control and rodent control should be done to prevent the "four pests" from spreading various diseases. It is necessary to prevent and evacuate dangerous areas such as landslides in time, and always maintain a high degree of vigilance to prevent problems before they happen and protect the safety of life and property.
