The car is an ideal place for lightning protection
If you are driving while thundering, try to stay in the car. Outside, the car is an ideal place to avoid lightning strikes, which is due to the Faraday cage effect.
Lightning experts said that the Faraday cage is a closed metal cage, the Faraday cage is charged, but its internal field strength is zero, so the people inside the Faraday cage are safe. Therefore, the car can also be regarded as a Faraday cage. The body will be charged with lightning strikes, but people in the car will not get electricity.
In case of lightning, do not rush to the road
Lightning experts say that when many people encounter lightning in the wild, the instinctive reaction is to walk quickly or even run. In fact, this is a taboo for lightning protection. Because the earth potential may form a potential difference when thundering, the pedestrian has a "step voltage" (the voltage between the two feet when a person walks on a ground with different potentials). If you walk fast or run, the "step voltage" is correspondingly large, and people are more likely to be injured.
In the wild, if you encounter lightning, you should evacuate to a house with lightning protection facilities or reinforced concrete buildings, away from high chimneys, trees, towers, telephone poles and other objects. If you don't have time to evacuate, don't run around. You can choose to squat under the low squat, put your feet together, hold your knees with your arms, and lower your head to reduce the exposed area of ​​the human body and the potential difference between the ground and the ground.
These places are vulnerable to lightning strikes -
1. Where soil resistivity is small, such as areas with metal deposits, river banks, groundwater outlets, and intersections where metal pipelines are concentrated, hubs for railway concentration, railway terminals, and corners of elevated transmission lines.
2. High water level and particularly humid areas, such as riverbeds, salt fields, ponds, lakes, low-lying areas and places with high groundwater levels. Because the probability of lightning strikes on the surface of the water is greater than that on land.
3. The hillside is bordered by rice fields.
4. Junctions with different resistivity (such as rock and soil).
5. Towering buildings, such as water towers, TV towers, flagpoles, etc.
6. Isolate and highlight the buildings and structures in the wilderness.
These lightning protection essentials must be remembered -
1. Pay attention to the lightning warning issued by the meteorological department when the weather changes.
2. Do not stay on the floor (house) of the building when thundering.
3. Pay attention to closing the doors and windows when thundering.
4. Do not get close to the exterior walls of buildings and electrical equipment when thundering.
5. Do not use solar water heaters when thundering.
6. Do not enter low-rise buildings (structures) such as shacks, posts, pavilions, etc. when thundering.
7. Do not hide under the big tree when thundering.
8. Do not raise objects such as umbrellas in the wilderness when thundering.
9. Do not work at the water surface or at the water and land junction when thundering.
