How do I escape a lightning strike outside? How to avoid lightning strikes during thunderstorms?

How can I avoid being struck by lightning when I am outdoors?

1) In order to prevent lightning accidents and stepping voltage injuries, it is necessary to stay away from the lightning rod and its grounding wire of the building.

2) Stay away from the tower. Chimneys, flagpoles, if possible, should enter buildings with wide metal frames, lightning protection facilities or metal shells of cars and boats, but canvas awnings, tractors, motorcycles, etc. are more dangerous in the event of lightning, and should be left as soon as possible.

3) Try to stay away from hills, seashores, rivers, and pools; Leave barbed wire and metal clothesline as soon as possible. Lonely trees and isolated small buildings without lightning protection, etc.

4) Try not to walk in the wilderness during thunderstorms. If you need to travel urgently, wear a raincoat that does not invade water, such as plastic; Walk slower and take smaller steps; Do not ride on livestock or walk on bicycles; Do not use umbrellas with metal rods, and do not carry tools with metal rods such as shovels and hoes on your shoulders.

Before being struck by lightning, people will suddenly have a feeling of hair standing up or trembling, at this time, they should immediately lie down on the ground, or choose a low-lying place to squat, feet together, arms around the knees, head down, as much as possible to minimize the exposed surface.

The correct way to prevent being struck by lightning in the field is as follows:

1. Lightning often strikes tall objects, therefore, during thunderstorms, pay attention to the terrain and landform, prohibit staying on the top of mountains or high hills, and do not approach tall trees, telephone poles, chimneys, billboards and other sharp and isolated objects.

2. When thunder, it is forbidden to stand in an open field, if you are in an open place, it is too late to take shelter indoors, you should immediately hold your knees with your hands, squat on the ground with your feet together, bend your body forward, your chest close to your knees, and look down at the ground, because your head is most vulnerable to lightning strikes. Do not use your hands on the ground, as this will increase the range of contact between your body and the ground, increasing the risk of lightning strikes.

3. During a thunderstorm, you can't stand under the big tree to hide from the rain, because standing under the big tree, when the strong lightning current flows into the ground through the big tree and spreads around, it will produce different voltages in different places, and the voltage difference between the two feet of the human body will cause injury, which is usually called step voltage injury. If you have to take shelter from the rain under a tree, you must keep a distance of 3 meters from the trunk.

Don't think that lightning is far away from us, there are many tragedies of lightning strikes every summer. Whether people are indoors or outdoors, thunderstorms are potential safety hazards. Here are some safety tips for preventing injuries during thunderstorms

4.When walking in the rain, you can't hold an umbrella with an iron handle, and you can't hold metal toys such as irons; When sheltering from the rain, observe whether there are exposed metal objects or electrical equipment such as water pipes and gas pipes around, and should not stay near iron fences, metal clotheslines, overhead metal bodies and railway tracks.

5.Try not to call or answer ** in thunderstorm weather, and avoid using the landline at home, because the lightning rod can only protect the building, but it can not do anything about the lightning waves that invade along the overhead wires and ** lines.

If there is a sudden thunderstorm outdoors, if possible. Run to the nearest settlement as soon as possible and take refuge from lightning through houses and buildings;

If you are working outside, such as farming or working on a construction site, you should immediately put down your work, abandon metal tools or objects, and then quickly take refuge in nearby houses.

Because the outdoor situation is uncertain, the weather of sheltering from thunderstorms should be determined in combination with the specific situation. But in general, don't hold metal objects in your hands, stay away from tall relatives buildings, and take refuge in wooden or stone houses.

Do not stay on the platform of high-rise buildings during thunderstorms, and do not enter isolated sheds, sentry boxes, etc. in outdoor open spaces. Keep away from exposed metal objects such as water pipes and gas pipes and electrical equipment outside buildings. It is not advisable to take shelter from a thunderstorm under a large tree, so you must keep a distance of 3 meters from the trunk of the tree as a last resort, squat down and keep your legs together.

When thunder and lightning are combined, there is a feeling of ants crawling away on the head, neck, and hands, and the hair stands up, so you should quickly lie on the ground and take off the metal jewelry, hairpins, necklaces, etc.

1.Be safety-conscious and discontinue outdoor activities as much as possible. You can seek lightning shelter nearby, such as caves, houses, etc., but it is not appropriate to enter shacks, sentry boxes and other low-rise buildings without lightning protection facilities. It is also not advisable to enter the metal trunk to hide from thunderstorms, let alone under big trees.

2.Pay attention to the topography and stay as far away as possible from mountain tops, water surfaces, or land and water junctions. In the southern water towns of China, people have a high frequency of activities on the water surface and at the junction of water and land, so the lightning strikes are particularly serious.

During the annual thunderstorm season, tourists must pay attention to stay away from the top of the mountain or other commanding heights when encountering thunderstorms; If you are in a forest, pay attention to choosing a place surrounded by trees and an open space in the middle to avoid lightning; It is generally safe to enter the cave, but do not lean against the edge of the cave.

3.Maintain good walking condition and eliminate potential safety hazards as much as possible. Do not walk in the rain with an umbrella with a metal handle, and do not touch railroad tracks or power lines.

You can't run in a thunderstorm, you can't ride a bicycle, and you can't ride a motorcycle. At the same time, when walking in residential areas and sheltering from rain, keep as far away as possible from exposed metal objects such as water pipes and gas pipes and electrical equipment outside buildings.

1. When you encounter a thunderstorm outdoors and have no time to leave a tall object, you should immediately find some dry insulation and put it on the ground, and sit on it with your feet together, and do not put your feet on the ground other than the insulator, because water can conduct electricity.

2. When sheltering from thunderstorms outdoors, you should be careful not to support the ground with your hands, hold your knees with your hands at the same time, keep your chest close to your knees, and keep your head down as much as possible, because your head is more susceptible to lightning strikes than other parts of your body.

3. When you hear thunder within a few seconds of seeing lightning outdoors, it means that you are in a dangerous environment near a thunderstorm, at this time you should stop walking, put your feet together and squat immediately, do not pull together with people, it is best to use plastic rain gear, raincoats, etc.

5. In thunderstorms, it is not advisable to drive a motorcycle quickly, ride a bicycle quickly and run wildly in the rain, because the greater the stride of the body, the greater the voltage, and the easier it is to hurt people.

In the event of lightning and thunder, do not stay outdoors or in the field, you should immediately go indoors, even a vehicle with a full metal compartment can become a lightning shelter.

If you suddenly encounter a thunderstorm in the field, you must keep in mind: keep your feet close together, try to lower the center of gravity, and reduce the contact area between the human body and the ground, so the best choice is to squat in a dry place, because the lightning current flows to the earth after the trumpet-shaped potential distribution curve, in the same soil situation, the larger the stride, the more likely it is to be struck by lightning. If you put on a raincoat that is not soaked in water, such as plastic, the lightning protection effect will be better.
