Seven people in Ganzi, Sichuan Province were killed by lightning while digging Cordyceps up the mountain. How to avoid danger in this extreme weather?

In the lawn and hillside areas of the plateau, cumulonimbus clouds move down closer to the surface, because the terrain is flat, and people may also become a safe passage caused by lightning in the clouds and be struck by lightning. If there is a standard, you must always check the weather forecast to prevent traffic in thunderstorms. In China, lightning-prone areas are concentrated in Yunnan Province, Guangxi Province, Guangdong Province, Hainan Province and its Qinghai-Tibet Plateau. The annual average thunderstorm days exceed 70 days. From June to August, thunderstorms occur in this place for more than one-third of the time every month. From this point of view, Chinese caterpillar fungus collectors are also desperately looking for Chinese caterpillar fungus on the grassland. However, due to the poor cell phone signal and untimely communication on the hillside and grassland in the plateau area, it is difficult for them to receive lightning warning information immediately, and usually they can only distinguish lightning to save themselves based on their work experience.

Tragedy meets thunderstorm, so stop work quickly. Pay attention to the following aspects when saving yourself: you can't gather when lightning strikes, and how many meters should be kept between people to prevent them from being together; If you are in high-lying areas such as peaks and mountains, you should evacuate quickly to save yourself; You don't need to hold a folding umbrella made of metal, and you don't need to bring metal accessories, keys, left and right, etc. , and the phone is turned off; Refuse to ride horses and bicycles, and try not to walk in the wild;

When binding outdoor tents, lightning protection devices such as lightning rods should be set up 5 meters away. Without lightning protection facilities, outdoor tents are at great risk of lightning, so don't go in to hide from the rain. Avoid towering and independent engineering buildings such as flowers and trees, poles and iron towers, and avoid hillsides, rivers and ponds; Don't avoid the storm at the mouth of the cave, under the rocks in Panyu or under the hanging rocks; Don't take shelter from the storm in a cold and seeping hole. Choose a deep and dry cave and go as far as possible to the innermost cave; Keep your feet closed and you can't touch the cave wall.

Finally, before being struck by lightning, people will feel that their hair suddenly stands on end and their skin is shaking. At this time, they should lie on the ground immediately. If there are low-lying places, they should quickly squat down with their hands on their heads to minimize exposure. After being struck by lightning, the partner will go to the rescue while ensuring his own safety and protection. After being struck by lightning, in addition to skin burns, there will continue to be suspended animation. At this time, you should unbutton your clothes according to the three steps of emergency rescue, then perform cardiopulmonary resuscitation (CPR) with professional counterparts, and finally gently press the cardiovascular system for more than 5 times. If people don't respond, they will repeat CPR and cardiac compression again.
