Seven villagers in Sichuan were killed by lightning while digging Cordyceps sinensis in the mountains. What warning does this incident give us?

In the west of shiqu county, Ganzi Prefecture, Sichuan Province, there is a Derongma township, which is located in a high mountain valley and belongs to a typical plateau monsoon climate, with a grassland area of nearly two million mu. It can be said that during this time of year, farmers in the village almost go to the local mountains to dig Cordyceps, but no one expected that this ordinary thing on weekdays: a sudden lightning strike actually killed seven people collectively. Before a lightning strike, some people may feel their skin shaking or their hair standing upright. Don't stand still at this time. You can choose a low-lying place nearby, with your arms around your knees and your feet together to minimize exposure. In addition, don't feel that you can be safe by setting up a tent alone. You need to set lightning protection devices, such as lightning rods, more than 5 meters away from the tent. What is the more important point? If a group of people encounter strong lightning weather, they should pay attention at this time. The crowd must not be crowded together for lightning protection. Everyone should keep a distance of several meters.

The way of self-rescue after lightning strike is mainly aimed at people around the lightning strike, because after being struck by lightning, not only the skin may be burned, but also the breathing and heartbeat may be lost. At this time, the first thing the person next to you should do is to call the emergency number, then lay the injured person flat and unbutton his clothes. Not everyone will die immediately after being struck by lightning, but it may be suspended animation. Before the rescuers arrive at the scene, people nearby can try mouth-to-mouth artificial respiration, and at the same time, they should have regular heart compressions to maximize the survival hope of the injured.

Some people may say that lightning disasters all happen suddenly. How can ordinary people judge accurately? In fact, the problem itself is not difficult. For example, you don't have such rich life experience, you don't know how to know the sky from the clouds, and you don't have obvious physical perception, but you can judge by the lightning disaster warning information or weather forecast released by the meteorological department. For example, after the shiqu county Meteorological Bureau issued a lightning warning, even if you are digging Cordyceps in the mountain, you should stop down the mountain immediately. Don't think about hiding under stones, caves or trees when it rains heavily, especially those wet caves. As for trees, iron towers and telephone poles, we should stay away from them.
