Matters needing attention in thunderstorm weather

When it thunders, a lot of negative ions will be produced in the air. When they collide with each other, an electric charge is generated. These negative ions will attach to relatively high objects, which will easily lead to lightning. When lightning strikes, it will bring a lot of current. Because the tree is not a good conductor, the resistance of the trunk is relatively large, so the current will stop flowing directly from the tree to the earth. In the process of people hiding from the rain in the tree, when the lightning of this big tree comes down and reaches the top of people's heads, an arc flashes down, hits people's heads after flashing, and then sprinkles down to the ground through the human body. That's the truth.

Knowing this common sense, people will not hide under trees. After all, people should cherish life.

Common sense of thunderstorm weather safety

1. Don't make a phone call or answer a phone call during a thunderstorm and lightning, but turn off your mobile phone, because the electromagnetic waves of telephone lines and mobile phones will lead to lightning injuries.

2. Don't turn on the TV, computer, VCD player, etc. During thunderstorms and lightning. Unplug all power plugs to avoid personal injury and electrical damage.

3, don't stand under the light bulb, don't take a shower.

4. Try not to go out. If you have to go out, you'd better wear rubber shoes and a raincoat, which can keep out lightning.

5. Try not to open the door or open the window to prevent lightning from hitting the room directly.

6. Don't stick your head and hands out of the window when you encounter lightning in the car.

7. Stay away from trees during a thunderstorm. Try not to run in big strides. You can choose buildings to shelter from the rain, but don't choose cars to shelter from the rain.

8. Don't connect the wires for drying clothes and bedding to the doors and windows.

9. Don't wear wet clothes, hats, shoes, etc. Walking in a thunderstorm. For sudden lightning, the height should be lowered immediately, and the feet should be close together to reduce the harm caused by the step voltage.

10, when lightning strikes, don't get close to all power facilities, such as high-voltage line transformers.
