How to protect yourself in thunderstorm weather indoors?

When a person is struck by lightning, the current quickly passes through the human body, causing different degrees of burns, which can cause respiratory center paralysis and cardiac arrest. In severe cases, brain tissue will die of lack of oxygen. Therefore, in the thunderstorm season, lightning protection should be highly valued. So, how to prevent lightning damage?

When near buildings and indoors, please pay attention to the following points:

1, can't stay on the roof and the roof, because most lightning strikes occur on the roof.

2. Close the doors and windows in time. For buildings with reinforced concrete frame structure, closing doors and windows can prevent the invasion of side lightning and ball lightning. Most ball mines enter the room along the chimneys, windows and doors of buildings. They move indoors for a few seconds and then escape, which is easy to cause an explosion.

3. When lightning strikes, don't get close to the exposed metal objects of the building, such as water pipes, heating pipes and gas pipes. , and away from the special lightning rod downlead. Because these metal pipes are often overcharged when they are struck by lightning, you will be overcharged as long as you touch them, and you will be injured or killed.

4. Electrical equipment without lightning protection facilities should not be used. This is because the lightning rod of the building can only protect the building, but it can't do anything about the thunder waves invading along the overhead line, telephone line or cable TV line.

How do people protect themselves outside the building in thunderstorm weather?

1, it is not suitable to open an umbrella or hold other metal objects in the wild. Because the metal objects such as umbrellas held high are conspicuous in the wilderness, they are easily hit by lightning guided by umbrella tips, resulting in casualties of umbrella holders. It has also been reported abroad that at the golf course, someone was struck by lightning while waving a club and pointing it into the air.

2. It is not advisable to enter isolated shacks, sentry boxes and other low-rise buildings. Because low buildings have no lightning protection facilities, and most of them are in the wilderness, they are high protrusions on the open space, which are easy to attract lightning strikes.

It is not advisable to hide under the big tree. When a thunderstorm comes, most people will naturally run under the big tree to hide from the rain. As everyone knows, they often avoid rain but cause thunderstorms. Because big trees are tall, they are often protrusions of a zone, which are easy to be struck by lightning.

4. It is not advisable to drive a motorcycle or ride a bike quickly. In thunderstorm weather, motorcycle lightning accidents happen constantly. These people think that motorcycles are fast and can avoid thunderstorms when they rush. In fact, motorcycles are not faster than lightning. Because the motorcycle body is mostly metal, it is more prominent in the wide expressway. Cyclists are easily struck by lightning when there is a strong thunderstorm at the zenith.

5. Outdoor ball games are not suitable. Playing outdoor ball games in thunderstorm days is easy to cause serious consequences of group death and group injury, which has been proved by many examples of lightning disasters at home and abroad. Especially football, because in the vast football field, a person is a cutting-edge discharge body, and the zenith is likely to be struck by lightning.

6. It is not suitable to work on the water surface or at the junction of land and water. In the southern part of China, especially in rural areas, people have a high frequency of activities at the junction of water and land, and there are many cases of lightning casualties.

In addition to the lightning protection precautions mentioned above, we also ask you to pay attention to the following points: when going out for an outing or production in summer, it is best to bring non-metallic rain-proof tools, such as plastic raincoats, wooden handles or umbrellas with plastic handles; When lightning strikes in the wild, it is best to remove the metal objects on your body and put them several meters away; Don't rush when it thunders, because the stepping voltage through the body is large when the steps are big, which is easy to hurt people; Don't set up metal antennas on the roof or roof casually, including clothes wire, because these metal wires are easy to attract lightning strikes; In case of unfortunate lightning strike, you should call the police for help in time, at the same time, give artificial respiration and extracorporeal heart massage to the injured or fake dead, and do your best to rescue them.
