How to teach you a few tips

"Naked room" without lightning protection device should be far away from the line

If I live in a "naked room" without a lightning protection device, how do I protect it against lightning? Mine experts warn that when thundering, do not use electrical appliances as much as possible, and do not go near indoor metal equipment, such as water pipes, water pipes, etc., do not approach wet walls, do not touch or near metal pipes, and water pipes connected to the roof. Stand under the light. It is best to remove the power supply of household appliances and the like. It is possible to introduce lightning into the indoor metal wires.

Car is an ideal place for lightning protection

If you are driving while thundering, you should try to stay in your car. Outdoors, the car is an ideal place to avoid lightning strikes. This is due to the Faraday cage effect.

Mine-protection experts said that the Faraday cage is a closed metal cage and the Faraday cage is charged, but its internal field strength is zero, so people inside the Faraday cage are safe. Therefore, the car can also be regarded as a Faraday cage, the body will be charged by the lightning strike, and people in the car will not provoke electricity. However, although it is safe to stay indoors during thunder, it is not foolproof. It is better to turn off the on-board electronic equipment such as GPS, car TV, CD, etc., so as to avoid causing the electronic system to malfunction.

Thunderstorm in the wild against lightning

Thunder can not afford to hide, but dodge the mine should also pay attention to methods. Lightning protection experts say that when many people experience thunder and lightning in the wild, their instinctive reaction is to walk or even run. In fact, this is a taboo for lightning protection. Because, when the earth is thundered, a potential difference may be formed. For pedestrians, there is a “stepping voltage” (people walk on the ground with different potentials and the voltage between the two feet). If you walk or run quickly, the "stepping voltage" is correspondingly large and people are more likely to be injured.

If lightning strikes in the field, it should be evacuated to a house or reinforced concrete building with lightning protection facilities, away from tall chimneys, big trees, iron towers, power poles and other objects. If you do not have time to evacuate, do not run around, you can choose to kneel down, feet close together, arms and knees, head down, to reduce the exposure of the human body and ground potential difference.
