What should I pay attention to when traveling in thunderstorm weather?

1, when it thunders, the first thing to do is to close the doors and windows to prevent lightning from hitting the room directly or preventing spherical lightning from floating into the room. When encountering thunderstorm, people should not stand under the light bulb, but cut off the power supply of household appliances to avoid damage. 3. In thunderstorm weather, try not to dial, answer the phone or use the mobile phone to surf the Internet. Unplug the power supply, telephone lines, closed TV lines and other metal lines that may introduce lightning. 4, indoor, should also be left with the driver's metal pipes and sewer pipes connected to the roof. Don't pull the wires used to dry clothes and bedding to the window or door, lest the wires cause death. Outdoor lightning protection 1, in thunderstorm weather, don't answer and call the mobile phone outdoors, because the electromagnetic wave of the mobile phone can also cause lightning. At the same time, it is forbidden to get close to some running power facilities when it thunders. Under normal circumstances, people will not be struck by lightning when riding a car, but never stick your head and hands out of the window when being struck by lightning when riding a car. 3. In case of sudden thunderstorm, when your hair becomes stiff and stands up, you should squat down, lower your height, and put your feet together at the same time to reduce the damage caused by stepping voltage. Don't take shelter from the rain under the big tree. It is best to stay 5 meters away from the tree when it thunders. 5. It is best to wear rubber shoes when going out in thunderstorm weather, which can play an insulating role. Lightning strikes have certain rules. Lightning strike is actually similar to the electric spark of charged body, which is a discharge phenomenon caused by electric field breaking through air. The tip of an object is densely charged, and the electric field nearby is strong, so it is easier to break through the air, and the discharge generates sparks. The conductor is easy to generate induced charges and discharge through the air. Therefore, objects protruding higher from the ground and objects with good conductivity are more vulnerable to lightning strikes. Lightning disasters can be prevented. On the basis of summing up experience, people have a further understanding of lightning disaster. The main measures to prevent lightning disasters are: 1. In the open field, don't let yourself be a sharp edge, that is, try to lower your height. Don't carry metal objects such as shovels, hoes and golf clubs over your head, because this will increase the chance of being directly struck by lightning. If there is nothing higher than yourself around, it will be dangerous to open an umbrella. The contact surface between human body and the ground should be reduced as much as possible to reduce the harm of step voltage. Find a valley or concave ground, and squat down on the flat ground with your feet together when necessary, which not only reduces the height, but also prevents the step voltage. In the suburbs, it is best to hide in buildings with metal doors and windows or lightning rods, or in cars with metal bodies. Once these buildings or cars are struck by lightning, their metal frames or lightning protection devices or the metal itself will lead lightning current into the ground. In the dense forest, it is best to find a clearing in the forest, choose a place as far away from the surrounding trees as possible, and kneel with your feet together. It is extremely unsafe to hide under a big tree to avoid thunderstorm, because this tall object is easily struck by lightning, which will produce lateral flashover, contact voltage and step voltage, and even cause death in severe cases. In addition, isolated huts, thatched cottages, pavilions, etc. Poor conductivity, easy to catch fire or collapse when struck by lightning. Stay away from these places in case of lightning. 4. Traveling in mountainous areas, such as Luyu Cave, can also enter lightning protection. Standing in a cave with your feet together, no part of your body can touch the wall or ceiling of the cave. Because the cave is a part of the earth's surface, once it thunders, contact voltage and step voltage may cause death. When there is lightning, it is best not to go fishing, boating or swimming in lakes, rivers and oceans, because these conductors are easy to attract lightning. Do not approach or touch any part of lightning protection equipment to prevent side flashover, contact voltage and step voltage. 6. During lightning, it is best not to ride a horse, bike, motorcycle or tractor in a flat open area, because you may become a prominent object in the surrounding environment and attract lightning strikes. 7. When lightning strikes, the room is relatively safe, but there are also many cases of casualties caused by lightning strikes. Most indoor casualties are caused by fires caused by lightning. In addition, many people are struck by lightning because they are close to or in contact with indoor metal pipes, such as water pipes, toilets and indoor circuits leading to household appliances. When lightning strikes a room without lightning protection device, lightning current will generally enter the room along telephone lines, lighting wires or outdoor TV antennas, and enter the ground along water pipes or wires. When people touch the above objects, their bodies become part of the lightning current path. When some metal pipes in the room are not well grounded, lightning current sometimes discharges from these conductors to the human body through the air gap. If the indoor ground and electrical lines are wet, lightning current will leak in the wet place. Just as people standing near the trees struck by lightning may suffer from lateral flashover and contact voltage, most cases of being struck by lightning indoors are also caused by lightning discharging to the human body through the air gap. Therefore, it is best to stay away from indoor bathroom pipes, sinks, telephones, household appliances and any metal objects connected with the outside world during lightning. In lightning-prone areas, or residential buildings, office buildings, workshops, factories, laboratories and other places, lightning protection devices can be installed indoors, which can short-circuit the lightning current entering the room to the ground along the wires.
