The harm of lightning to human body is caused by the direct action of current, overpressure, electricity and high temperature. When a person is struck by lightning, the current will pass through the human body quickly. In severe cases, it will lead to heartbeat, respiratory arrest and brain tissue hypoxia and death. In addition, the sparks generated by lightning strikes can also cause skin burns to varying degrees. Therefore, the following precautions should be paid attention to in thunderstorm weather.

1. When there is a thunderstorm and lightning, don't call and answer the phone, but unplug the telephone line. The mobile phone can be used normally! But generally try not to answer the phone outdoors or indoors near the window.

2. Don't turn on the TV, computer, vcd player, etc. During thunderstorms and lightning. Unplug all power plugs, turn off household appliances, unplug power plugs, and prevent lightning from invading from the power cord.

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.

1 1. When outdoors, avoid in time and don't stay in the empty suburbs. When there is nowhere to hide in the open countryside, don't run, don't bump into objects such as umbrellas, try to find a low-lying place (such as a pit) to hide, or put your feet together and squat down on the spot.

12. Immediately stop outdoor swimming, boating, fishing and other water activities.

13. If many people gather outdoors, don't crowd each other to prevent the power supply from being connected to each other after being struck by lightning.

Common sense of flood control safety

In a short period of continuous rainstorm, the river will rise violently, overflow dams, flood farmland and villages, destroy roads, bridges and houses, and cause casualties and property losses. Therefore, we should attach great importance to flood control safety.

1. Insist on listening to the weather forecast every day, keep abreast of local weather changes, and pay attention to weather signs: it is sultry in the morning, and even difficult to breathe, which is generally a sign that the low-pressure weather system is approaching, and heavy rainfall often occurs in the afternoon; In the morning, I see the pagoda-shaped ink cloud uplift in the distance, and there will usually be strong thunderstorms in the afternoon; For several days in a row, the weather was clear and cloudless, especially hot. Suddenly, I saw a small cloud rising on the windward slope of the mountain, and there was usually a strong thunderstorm at midnight or early morning. When you see funnel-shaped clouds or dragon's tail clouds on the horizon, it means that the weather is extremely unstable and there is the possibility of thunderstorms and strong winds at any time.

2. Don't watch the flood; Don't walk under the mountain, don't walk in low-lying places, and don't stay in ravines and low-lying places; Don't shelter from the rain under trees, fences and rocks; Don't cross the river if you don't know the water.

3. Move as soon as the flood comes. When it is too late to move, you should immediately climb the roof, tall buildings, big trees, high walls and other places to temporarily avoid danger. At the same time, seek help from the outside world by calling for help, making fireworks and waving colorful clothes. If there are floating objects such as boats, rafts, door panels, barrels, pots and cans, you can save yourself.

4. In case of landslide, you should look around quickly and disperse to a safer place. When evacuating, it is very dangerous to run in both directions as the best direction, whether to run down or up.
