Thunderstorms are very dangerous. How should we protect ourselves in the face of lightning?

Lightning is a common natural phenomenon. In essence, it is the spark discharge of thunderstorm clouds in the sky. The light produced during discharge is lightning. The loud sound of lightning heating and expanding air is thunder. In thunderstorm weather, wear metal jewelry as little as possible, and don't stay on the top of the mountain, ridge or roof. Not suitable for outdoor activities, nor for staying in open places such as playgrounds and squares. At the same time, be careful not to lift the umbrella and other items too high, so as not to increase the effective height and become a tip and be struck by lightning.

When you encounter a thunderstorm when you go out, you should avoid it in time and don't stay in the open field. Don't swim or row in the river to prevent lightning from being transmitted to the human body through water. When there is lightning, if you inevitably hide in the open field, you should try to find a low-lying place (such as a pit) to hide, or squat down immediately, with your hands folded, your arms folded, your head bent down, and your body height reduced as much as possible. It is especially important to note that when encountering lightning, don't stand under flagpoles, trees, chimneys and telephone poles, stay away from metal objects such as doors, windows and heaters, and don't stand barefoot on the soil or concrete floor. These places are the most vulnerable to lightning strikes.

If you encounter lightning weather outdoors, you should quickly find a lightning protection place. Don't choose the external wall of the building, stay away from exposed metal objects of the building, such as water pipes and gas pipes, stay away from outdoor power equipment, such as substation boxes and distribution boxes, and don't take shelter from rain in small lightning-proof buildings in the open space, such as isolated shacks, sentry boxes, trees, shacks, shacks and umbrellas. If the outdoor high-voltage line is broken by lightning, don't run, because the voltage is conducted from the grounding point to the outer hemisphere. At this time, if you step, a step voltage will be generated. The bigger you walk, the higher the voltage between your feet. There will be an electric current passing through your feet, which will cause your legs to cramp. At this point, you should put your feet together and jump out of the scene.

Children must be warned not to play with mobile phones in thunderstorm weather, and try not to call or answer the phone. There is a fixed telephone at home, but it should be avoided, because lightning rods can only protect building objects from sharp monitoring lines and are vulnerable to lightning strikes. If you are in the forest, try to hide under some low-lying trees; If you are in an empty suburb, hide in a low-lying gully or valley and stay away from those natural lightning rods, such as a lonely tree in the suburbs; If you are in the water, go ashore and find a place to shelter from the rain.
