In the hot summer season, the weather is highly convective, with frequent thunderstorms and lightning damage, which brings many inconveniences to people's lives and travel. In order to achieve lightning protection and reduce the occurrence of lightning accidents, it is necessary for us to understand some lightning protection knowledge.
When people go out, they must pay attention to listening, watching or checking the local weather forecast online at any time to determine whether there is thunderstorm weather. When thunderstorms occur, it is necessary to quickly hide in buildings or deep caves protected by lightning protection devices. The car is also an ideal place to avoid lightning strikes.
If it is impossible to hide in lightning protected buildings in the wilderness, one should stay away from tall and isolated objects such as trees, power poles, chimneys, etc. It is not advisable to stay near iron fences, metal clotheslines, overhead metal bodies, and railways. It is not advisable to enter low rise buildings such as isolated sheds and guardrails in the wilderness without lightning protection devices. Keep away from power transmission and distribution lines, overhead communication cables, etc. Try to avoid small areas that are particularly susceptible to lightning strikes, such as rock faults, large rock fractures, and ground exits of buried pipelines.
When encountering lightning and thunder above your head, if you cannot find a suitable lightning protection place, you should find a low-lying area, try to lower your center of gravity and reduce the contact area between your body and the ground. You can squat down, put your feet together, place your hands on your knees, bend forward, and temporarily avoid it. Do not lie on the ground. If you put on a raincoat, the lightning protection effect will be better. If there are many people, don't gather together or hold hands and lean against each other.
Do not use metal umbrellas in open spaces. Do not carry shovel and other farm tools on your shoulders. When squatting down for lightning protection, put down the metal objects on your body and place them several meters away, especially take off the metal frame glasses you wear.
Do not use mobile phones in the wild, swimming or engaging in other water sports and operations is prohibited, outdoor ball games, climbing, riding and other sports are not suitable, it is not advisable to drive motorcycles or bicycles on the road, and avoid running wildly during thunderstorms.
When lightning strikes, it is relatively safe to hide indoors, but this is also relative to outdoors. If measures are not taken indoors, in addition to direct attacks from spherical lightning, there is also a possibility of indirect lightning strikes.
Therefore, when encountering thunderstorm weather, it is necessary to close doors and windows indoors. Try to stay away from metal doors and windows, metal curtain walls, or places with power sockets. Do not stand on balconies, or barefoot on mud or cement floors. Do not place non-conductive objects under your feet or sit on wooden chairs. Do not approach or touch any metal pipelines, including water pipes, heating pipes, gas pipes, etc.
If there is no lightning protection device in the house, do not use any household appliances indoors, including televisions, computers, radios, telephones, washing machines, microwave ovens, etc. Unplug all power cords, network cables, and telephone cables.
In summary, lightning protection knowledge can be summarized as follows:
Don't panic when encountering lightning, stay away from isolated metal objects,
Cut off the power and lower the height. Do not use it as a lightning rod.
