All the heavy rainfall in Hebei stopped offline teaching. How to prevent casualties caused by secondary disasters?

There will be heavy rainfall in Hebei Province in the near future, and the Hebei Provincial Department of Education also requires all offline teaching to stop to prevent casualties caused by secondary injuries. How to prevent secondary injury? First of all, we must make early warning, and we must avoid risks scientifically when we encounter injuries.

1. At present, Hebei Province has entered a state of heavy rainfall, so as an ordinary person, how to prevent the secondary injury caused by heavy rain? At this point, we must first make early warning and avoid risks scientifically. Early warning first means that in the face of extreme weather and unstable weather, local meteorological bureaus must monitor, forecast and warn in time to improve the fine forecast of meteorological disasters in the province and win valuable time for disaster prevention.

Second, we should also pay attention to key reservoirs and infrastructure in Hebei Province. It is necessary to further refine the meteorological support plan to ensure that every meteorological disaster can be effectively prevented, and release information as soon as possible through information release channels to speed up the early warning of meteorological disasters. At the same time, ordinary people must do a good job in scientific hedging, because Hebei Province has a complex terrain, and long-term heavy rain may cause various geological disasters such as mountain torrents, mudslides and landslides, and may also cause urban waterlogging.

Third, how to judge whether there is a mudslide? First of all, we should observe the flow of the river. If the water flow in the river suddenly stops or increases, accompanied by more branches and weeds, it can be judged that debris flow has formed in the upper reaches of the river. Second, you can use the method of listening to the sound. If there is a sound like a train or thunder above the river, we must attach great importance to it, even if the sound is very small, it means that mudslides are forming. People living in mountainous areas must pay close attention to the official weather forecast. If people living in the upper reaches of the river find that mudslides are forming, they must immediately notify the downstream basins that may be affected to avoid causing more casualties.
