Where should lightning weather be avoided?

Lightning weather is not suitable for hiding under big trees, under metal cars, near telephone poles or high-voltage electricity.

This is because when standing under a big tree, when powerful lightning flows into the ground and spreads around the tree, it will produce different voltages in different places, and the voltage difference between human feet will cause harm, which is usually called step voltage injury. If you have to hide under the tree to avoid the rain, you must keep a distance of 3 meters from the trunk.

In addition, when it thunders, it is forbidden to stand in an open field. If you are in an open place and have no time to escape indoors, you should immediately kneel on the ground with your knees in your arms, your feet together, lean forward, keep your chest close to your knees, and look down at the ground, because your head is most vulnerable to lightning. Never support the ground with your hands, which will expand the contact range between your body and the ground and increase the risk of being struck by lightning.

During a thunderstorm, we should pay attention to the topography, prohibit staying at the top of the mountain or in hilly areas, and do not get close to sharp and isolated objects such as tall trees, telephone poles, chimneys and billboards. You should stop outdoor activities immediately and find a lightning protection place as soon as possible. You can take refuge in low-lying, dry or leeward houses or caves. However, low-rise buildings without lightning protection facilities, such as shacks and sentry boxes, cannot enter.

In addition, when there is lightning, thunder and rain, everyone should immediately turn off the indoor TV, tape recorder, stereo, air conditioner and other electrical appliances to avoid using electricity. It's safer in the middle of the room when it thunders. Don't stay under the electric light, and don't lean against posts, walls, doors and windows, so as to avoid accidents caused by induced electricity when it thunders.

Extended data

Taboo of thunderstorm weather:

1. When avoiding thunderstorm outdoors, be careful not to support the ground with your hands, and at the same time, put your knees in your hands, keep your chest close to your knees, and keep your head as low as possible, because your head is more vulnerable to lightning than other parts of your body.

When you see lightning outdoors, you hear thunder within a few seconds, which means you are in a dangerous environment near a thunderstorm. At this time, you should stop walking, put your feet together and squat down immediately. Don't get involved with people. It is best to use plastic rain gear and raincoat.

3. It's best to turn off the TV, computer and other electronic equipment when it thunders and lightning, because it is easy to damage the electronic equipment that can receive external information in thunderstorm weather, and in order to avoid these devices from conducting electricity and hurting people, it is necessary to minimize their use in thunderstorm weather.

4. Try not to get close to metal equipment when indoors, and don't touch conductive metal equipment such as antennas, water pipes, metal doors and windows. Don't put your clothes on the wire, stand directly under the electric light, these are very easy to conduct electricity.

Don't play near the rivers and lakes in thunderstorm weather, it's dangerous. In addition, when it rains, many fish will stir up, which also attracts many anglers to fish. But it is very dangerous to do so. Water is a conductor, and fishing in rainy days is prone to electric shock accidents.
