On July 21, a camphor tree on the Qingximen Street in Taiping Town, Shuangliu County, Sichuan Province was struck by lightning, causing fire on the wires along the trees. The surrounding nine houses were damaged by fire, and three of them were almost burned. As soon as the news came out, many villagers were afraid: this summer, lightning weather is frequent, how to prevent lightning in rural areas? When it comes to thunderstorms in the field, what should I do? If people and animals unfortunately encounter lightning strikes, how should they be rescued? With these questions, on July 28, the reporter interviewed Xu Zhimin, deputy director of the Sichuan Lightning Protection Center. Rural lightning protection fragile trees are easy to lead lightning strikes "Rarely, the disaster caused by lightning disasters in rural areas is even greater, because farmers' awareness of lightning protection is relatively weak." Xu Zhimin said that summer is a frequent period of lightning, and it is also a busy season, so rural areas occur. The probability of a lightning disaster is greater. In addition, due to the relatively complex rural terrain, the field is relatively empty, which is the most likely place for lightning disasters. As a result, lightning strikes that cause casualties in rural areas mainly occur in relatively open fields. And the trees in front of the house in front of the rural house are also likely to cause lightning strikes. The accident on the Qingximen Street in Taiping Town, Shuangliu County, Sichuan Province on July 21 was for this reason. Fu Xiulong, director of the Taiping Town Safety Supervision Office, said: "The camphor tree was struck by lightning, and the lightning was led to the wire and caught fire. The wires were next to the roof of these houses." Eventually, it caused an uncontrollable disaster. Building lightning protection must be "repaired" inside and outside “On June 13, 2009, more than 10 households in a certain area of ​​Jicheng Town, Jiyuan City, Henan Province were struck by lightning. The TV antennas of these residents were only left with a thread, and the switches, knives and electric lights were all damaged. The lightning protection of rural buildings requires both external protection and internal protection," said Xu Zhimin. First of all, because many farmers lack lightning protection knowledge, most of them have laid wires and telephone lines (cables) overhead, and some even used to stand the antenna directly on the roof. In fact, without any external protection, it is very dangerous, and it is easy to attract lightning strikes. Once a lightning strike occurs, the induced current caused by lightning current or lightning induction may enter the room along the TV antenna, damage the household appliances, burn the home line, and even hurt people. Second, we must pay attention to internal protection. Before the power, signal, etc. enter the room, it is necessary to install some lightning protection devices, which is a problem that few people will notice in the countryside. Many people always think that the occurrence of lightning strikes is a small probability event, and it is not necessary to install protective devices in order to save trouble. Once a lightning strike occurs, the consequences are likely to be unimaginable. Xu Zhimin said that nowadays, rural houses are getting better and better, and they are getting higher and higher. However, the protection awareness of peasant lightning has not kept up, which increases the probability of lightning disasters. Therefore, it is best for farmers to start planning from the initial stage of building a house and design it in strict accordance with the lightning protection standards of the house. Only in this way can they be protected from lightning damage. Field work in the thunderstorm In recent years, it has been common for farmers to suffer casualties from lightning strikes while working in the field. Xu Zhimin pointed out that when people work in the field, they are in an open space. At this time, people are relatively high objects and are vulnerable to lightning strikes. At the same time, farmers may hold tools such as steamed bread when they are working on farms. These tools will further increase the height of the human body, thus increasing the probability of being hit by lightning. "If you encounter thunderstorms in the field, you should avoid looking for big trees to avoid the rain, but you should try to reduce your height as much as possible, such as putting your feet together and throwing away the tools in your hands." Xu Zhimin suggested that the most A good way is to find a safe place as soon as possible and reduce the time it is exposed to lightning strikes. Solar energy has become a “lightning deviceâ€. Solar water heaters are now emerging in rural areas. Xu Zhimin said that the solar water heater is installed at the top of the building. If the lightning protection device is not perfect, it will become a lightning protection device. Once the lightning strikes, not only will the solar water heater be damaged, but the lightning current will also enter the bathroom and indoor wire network along the water pipes and power lines, which may cause damage to the indoor electrical appliances, and may cause personal injury or death. Therefore, when installing a water heater, it is best to ask professional technicians to install lightning protection facilities. How to rescue if you are struck by lightning "A person who is struck by lightning may be burned or severely shocked, but the body is not charged and can be safely disposed of and rescued." Xu Zhimin said that lightning damage to the human body is much more serious than ordinary electric shock. Once someone is found to have been struck by lightning, first dial 120 and let the injured person be rescued on the spot. "First hit the injured person on the back, and continue to do artificial respiration and chest massage, until the wounded's breathing, heartbeat returned to normal." Xu Zhimin said that the wound burned by lightning can be restored according to the treatment of burns. Because of the phenomenon of suspended animation in the case of lightning strikes, artificial respiration and heart massage should continue until the injured person has died. "Remember, lightning strikes, no matter what state, should insist on rescue, until 120 medical staff arrived." Xu Zhimin stressed.
