Lightning disasters occur frequently in summer to increase lightning protection measures

At the end of May, a lightning strike in Chongqing caused the death of 7 students, which sounded the alarm bell to prevent lightning disasters in summer. Since the beginning of summer, severe lightning weather has occurred frequently in some provinces and cities, resulting in casualties in some areas, the highest in the same period of the past years, and the high thunderstorm period in July and August.

Liu Cong, director of the Jiangsu Lightning Protection and Disaster Reduction Bureau, believes that through lightning protection popularization and promotion of awareness of lightning protection, the number of deaths from lightning strikes can be reduced to zero. According to lightning protection experts, do n’t rush when thundering, because “thunder and run”, one-step off-the-earth will generate a stepping voltage. When you run, the step increases, and the stepping voltage generated after the lightning strikes the ground and enters the body is large, which is easy to hurt. people.

"There is a spherical thunder, like a fireball, that will run around as the air moves. Not long ago, the spherical thunder that was produced during a thunderstorm in southern Jiangsu was hit by a citizen. Fortunately, when he felt his body Hemp, when the hair is upright, he stopped striding forward, and then survived. Otherwise, take another step, and the consequences are unbearable. "Liu Cong, director of the Provincial Bureau of Lightning and Disaster Reduction, explained by example.

Lightning protection experts said that side thunder and spherical thunder are the most like to "slip and crawl", and enter the room from doors and windows, chimneys, etc. When the thunderstorms come, the public should pay attention to close the doors and windows, and stay away from the wall, do not touch the room In the metal pipelines, water pipes, heating pipes and other metal objects inside, when the lightning occurs, the feet should be brought upright and the body should squat as much as possible.

The lightning disaster has attracted the attention of governments everywhere.

Jiangxi Provincial Meteorology and Media Team Up to Increase Lightning Propaganda

Since June, Jiangxi Province has experienced frequent thunder and lightning weather, which has caused casualties in some areas, the highest in the same period of the past years. According to the analysis of the disaster situation, all deaths from lightning strikes are concentrated in the countryside, and 70% of the deaths are due to work in the field. , In the wild, or caused by improper avoidance.

Recently, in order to ensure the safe operation of the business system, the Science and Technology Department of the Bank of Jiangsu Huai'an Branch conducted a comprehensive inspection of the lightning protection facilities of the central computer room, cleared the safety hazards of the existing lightning protection facilities, and made additional investments to upgrade the lightning protection facilities And transformation.

How to prevent lightning strike accidents from recurring? Lightning protection legal support

Lightning strike calls for legal support

On the afternoon of June 4th, a lightning strike accident occurred in a forest farm area in Luoding City, Guangdong Province, killing 5 people and injuring 3 others. At that time, eight Yunnan migrant workers were resting in the work shed in the work area, but were struck by lightning. Five of them were comatose on the spot and died after medical staff failed on-site rescue. The three wounded have been sent to the Weidi Township Hospital in Luoding City for treatment. There is no danger of life.

Lightning strikes occur frequently

According to data from the Lightning Protection Center of the Inner Mongolia Autonomous Region, from 2003 to 2006, lightning strikes occurred frequently in Inner Mongolia, causing a total of 37 deaths. In 2005, 17 people were killed and 34 people were injured due to lightning strikes, and the losses were as high as 18 million yuan. This was the most serious year of casualties and property losses suffered by lightning strikes in Inner Mongolia in recent years.

The "May 23" lightning strike in Kaixian County, Chongqing, caused 7 deaths and 44 injuries, which attracted wide attention from all walks of life. But shortly after the accident, a lightning strike occurred in Yihe Town, Kai County, Chongqing, causing 1 death and 1 injury. At 8 o'clock on the morning of May 21st, the local thunderstorms were mixed, and a group of farmers in the town and village, Luo Xinyou, was having breakfast with his wife at home. Suddenly there was a loud thunder, and Luo Xinyou and his wife were struck by lightning. Luo Xinyou was killed by lightning and his wife was injured. .

Is the accident just a natural disaster

After the accident, Zhang Xuewen, deputy director of the Kaixian Meteorological Bureau, said: The focal point in that place was the trunk and branches. After the whole tree introduced the lightning, it caused this lightning strike.

Zhang Xuewen said that the big tree was the main culprit in attracting thunder into the room. In addition, the walls around the classroom were damp, and the window frame was made of screw steel. The absence of glass was also an accomplice to the incident. Therefore, in this lightning strike, the dead and injured students were all close to the wall. He said: The lightning protection equipment of Xingye Village Primary School is a decoration.

Since there is a hidden danger of lightning protection in Xingye Village Primary School, why is there no lightning protection facility installed? Zhang Xuewen explained that the mandatory installation of lightning protection facilities has been required since 1998, and the country has not explicitly stipulated that bungalow schools must be equipped with lightning protection facilities. In addition, rural schools have poor awareness of lightning protection, financial resources are difficult, and lightning protection work has also been carried out. difficult.

Can we eliminate human disasters

The main cause of the "May 23" lightning strike has been basically identified: 16: 00-16: 30 pm on May 23, the classroom of Xingye Village Primary School in Yihe Town was repeatedly struck by lightning and accompanied by the occurrence of spherical lightning. When directly hitting the metal window of the classroom, because the metal window is not grounded, the lightning current has no place to discharge, and the student near the window becomes a channel for the lightning current to discharge into the ground. The thermal and mechanical effects of the lightning current cause the student to appear casualties.

Relevant departments said that the accident was a natural disaster, not a human disaster, and there was no compensation problem, but it would provide subsidies to families of the students who died. The relevant person in charge of the Chongqing Kaixian Meteorological Bureau said that due to the special factors of meteorology, environment, geography and topography, this lightning strike accident resulted. First, according to the weather background and the time of the accident, the classroom is in the area of ​​severe thunderstorm weather control area. Second, the geographical location and topographical characteristics of the classroom and the nature of the building itself are vulnerable to lightning strikes. Third, there is a row of large trees about two meters away from the classroom. Due to the existence of this large tree, the probability of the classroom being struck by lightning is increased. Fourth, there is no lightning protection device in the classroom. According to the lightning protection design specifications of the building, the classroom does not require mandatory lightning protection requirements. At the same time, the height of the building is less than 15 meters. The main reason is the geographical terrain location, so this time the reason The main reasons are these. On the other hand, according to expert analysis, the accident classroom suffered multiple lightning flashes, accompanied by the occurrence of spherical lightning, resulting in multiple lightning strikes and casualties in the classroom. On the other hand, when the lightning directly hits the metal window of the classroom, because the metal window is not grounded, the lightning current has no place to discharge, and the students near the window become a channel for the lightning current to be put into the electricity, and the electrical effect of the lightning And thermal effects, causing casualties.

Major General of Lightning Protection Facilities of Some Schools in Hainan Province Strengthens Inspection

The reporter learned from the Provincial Meteorological Observatory yesterday that since the beginning of this year, lightning disasters have occurred frequently in our province.
