Prevention and survival methods of lightning strike

In rainy days, the charges in the clouds can form a powerful current to attack the ground. Ordinary lightning can generate tens of thousands of volts in an instant, so many towering objects, including buildings and trees, may be destroyed. After the human body is struck by lightning, the light person is injured, and the heavy person can be disabled or even killed.

10.2.4. 1 survival method

1) insulation method. When struck by lightning, jump onto a dry nonmetallic object below, and immediately bow your head and sit down.

2) group law. Curl up like a hedgehog, put your hands around your calves, rest your head on your knees, and keep your hands and feet on the ground.

3) Short circuit method. When lightning strikes, there will be some precursors, similar to being attacked by static electricity, and then, after about 2 ~ 3 seconds, a powerful current comes. At this point, there is nowhere to escape. The only way is to put your hands on the ground and lower your head, hoping that the charge will spread from your arms to the ground to avoid damage to your internal organs.

4) When people encounter electric shock in the wild, they may have symptoms such as burns, paralysis of lower limbs, blindness and dyspnea. It's inconvenient to move at this time, even if you climb, you must persist. The chances of survival at this time mainly depend on a person's willpower.

10.2.4.2 preventive measures

1) In rainy weather, especially in rainy season, stay away from mountain tops and highlands, where lightning often patronizes.

2) Trees, especially those wet by rain, have certain conductivity, and will conduct the current received from the air to the ground. So, don't take shelter from the rain under isolated trees.

3) When lightning strikes the ground, within a certain range, tall objects will contact the current first. Therefore, in rainy days with lightning, don't let yourself be the highest point within the range of Fiona Fang 1 km.

4) Metal has strong conductivity and has the characteristic of preferential contact with lightning. Be sure not to get close to large metal objects outdoors.

5) At the seaside, don't stand on rocks in rainy days.

6) When establishing a workstation in the field, be sure to install a lightning rod.

7) When working in the field in thunderstorm season, it is best to wear insulated shoes if possible.

8) When camping in the field in thunderstorm season, how to avoid lightning strike should be considered in advance.
