How to protect yourself in thunderstorm weather

First, how to protect yourself in lightning weather?

How can we avoid or reduce lightning casualties and protect people's lives? According to experts, lightning strikes cause casualties, mainly in the wild, near buildings and indoors. So, how to prevent lightning damage?

1, near buildings and indoors, the following four points should be noted:

First of all, you can't stay on the roof.

1996 On August 8th, 2006, at 4am, Sun Mou, Heyuan City, Guangdong Province 16-year-old son was watching TV at home. Because the TV receiving antenna was faulty, he ran to the top of the building to play with the antenna. There was a thunder, and he died unfortunately. This is because most lightning strikes occur at the top of buildings.

Second, we should pay attention to closing the doors and windows.

For buildings with reinforced concrete frame structure, closing doors and windows can prevent the invasion of side lightning and ball lightning. Most ball mines enter the room along the chimneys, windows and doors of buildings, and escape after a few seconds of indoor activities, which is easy to cause explosions. 65438+1At 6 o'clock in the morning of May 29, 1995, a family of four surnamed Zhang in Shihuiyao Village, Xiuyan Manchu Autonomous County, Liaoning Province was asleep. A cloud of lightning entered the room along the window, and then exploded, causing the house to catch fire. A four-year-old girl, a nine-year-old boy and his wife were killed by lightning.

Three, when lightning strikes, should not be close to the exposed metal objects of buildings, such as water pipes, heating pipes, gas pipes, etc. , and should be far away from the special lightning rod downlead.

1on the afternoon of June 5, 993, the office of a police station in Beijing was struck by lightning, and the vice captain who was on the phone was knocked down, and everyone who touched metal objects indoors was shocked.

Fourth, electrical equipment without lightning protection facilities should not be used.

1986 It is reported that five people were killed by lightning under indoor lighting and switches in Hunan. 1On the evening of August 9, 994, four women in a village in Xinmin County, Liaoning Province sat around the kang and watched TV. Lightning comes in from the outdoor antenna, causing machine damage and personal injury. This is because lightning rods can only protect buildings, but they can't do anything about lightning waves invading along overhead power lines and telephone lines.

2. How do people protect their safety outside the building in thunderstorm weather?

First, it is not advisable to enter low-rise buildings such as shacks and sentry boxes.

1On July 9, 1994, 66 migrant workers were struck by lightning in a shed in Nanzhang County, Hubei Province, causing 14 serious injuries and 25 minor injuries. Because low buildings have no lightning protection facilities, and most of them are in the wilderness, they are high protrusions on the open space, which are easy to attract lightning leaders.

Second, it is not advisable to hide under a big tree.

When the storm comes, most people will naturally run under the big tree to take shelter from the rain. As everyone knows, they often shelter from the rain but bring disaster. 1In July, 1995, more than ten students in Wutang Town, Suixi County, Guangdong Province were struck by lightning while sheltering from the rain under a big tree, causing two deaths and six injuries on the spot.

Third, it is not advisable to hit metal objects such as umbrellas in the wild.

1994 On the afternoon of July 6, Gu Mou, a village in Dafeng County, Jiangsu Province, grabbed an umbrella in a cotton field and hurried home. Unfortunately, he was killed by lightning. His clothes were smashed into dozens of pieces, and there was a small hole in his chest and armpit, leaving only a shelf for holding an umbrella. 1998 on the morning of may 17, a Henan couple working in Zhongshan city, Guangdong province, rode bicycles in the rain. When they passed a bridge deck, they were suddenly struck by lightning and both of them were killed. The wife sitting in the back seat was holding an umbrella with a metal handle. Lightning was guided by the tip of the umbrella, and the rear wheel of the bicycle was seriously damaged. The cement bridge deck is 5 cm deep and covers an area of nearly 200 square centimeters. It has also been reported abroad that someone was struck by lightning when waving a stick in the air.

Fourth, it is not suitable for working on the water surface or at the junction of land and water.

In the south of China, especially in rural areas, people move frequently at the junction of water and land, and lightning casualties are particularly serious. 1On August 3rd, 995, three children were struck by lightning in a management area of Lecong Town, Shunde City, Guangdong Province. One child of 1 1 died unfortunately, and the other two children fell to the ground.

Fifth, it is not advisable to drive a motorcycle or ride a bike quickly.

In thunderstorm weather, motorcycle lightning accidents happen constantly. People who are injured by lightning when driving motorcycles may be lucky, thinking that motorcycles are fast and can shelter from the rain as soon as they rush. In fact, motorcycles can't be faster than lightning. 1June, 996 12 At 4 o'clock in the afternoon, a female intern named Xie in Bingcun, Meizhou City, Guangdong Province was struck by lightning on her way home by motorcycle.

Sixth, outdoor ball games are not suitable.

Playing outdoor ball games in thunderstorm days is easy to cause serious consequences of group death and group injury, which has been proved by many examples of lightning disasters abroad. 1On September 20th, 993, four players were killed in a football match near Kuala Lumpur, Malaysia. 1June, 996 14 At 7: 00 pm, a group of college students from the Department of Mechanical and Electrical Engineering of Guangdong University of Technology played football in the school football field in the rain. He was knocked down on the 5 th, and two of them were taken to the hospital for rescue. In view of the lightning accident of outdoor sports, the Organizing Committee of 1998 World Cup installed a large number of advanced lightning protection equipment in the main football stadiums in France.

In addition to the precautions mentioned above, we also give you the following suggestions: when going out for an outing or production in summer, it is best to bring non-metallic rain gear, such as plastic raincoat, wooden handle or umbrella with plastic handle; When lightning strikes in the wild, it is best to take off metal objects and put them several meters away; Don't rush when it thunders, because the stepping voltage through the body is large when the steps are big, which is easy to hurt people; Don't casually erect metal antennas on the roof or the roof, including wire for drying clothes. In case of unfortunate lightning strike, colleagues should call the police for help in time, and at the same time do artificial respiration and extracorporeal heart massage for the injured or fake dead.

Second, the top ten "secrets" of personal lightning protection
