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.

Therefore, if the school is not built on a hillside, if there is no big tree next to the classroom, and if the threaded steel window frame is grounded, the accident may not happen.

Indoor lightning protection is equally important

Lightning strike accidents occur frequently, and lightning protection knowledge and actions are particularly important. Previously, people mentioned lightning protection knowledge, mostly in the outdoors. In fact, indoor lightning protection is equally important. Be sure to close the windows when there is thunder and lightning. Be careful not to be close to metal pipelines, water pipes, heating pipes, gas pipes, etc., because those places are easy to pass thunder current.

In addition, keep away from the outer wall, that is, the outer edge of the wall, because it is also closer to the lightning discharge channel.

Turn off electrical appliances, including televisions and refrigerators. You can't just turn it off with the remote control, but turn off the power completely.

Units and individuals have tips for lightning protection

Thunderstorms occur frequently in summer, how to prevent lightning and reduce disasters? China Meteorological Administration recently reminded the public of the six major methods and ten tips for lightning protection.

Six measures for unit lightning protection:

The unit shall regularly inspect lightning protection facilities by a qualified professional lightning protection inspection agency to assess whether the lightning protection facilities meet the requirements of the national regulations.

The unit shall establish a person responsible for preventing lightning disasters, be responsible for lightning protection safety work, establish various lightning protection and disaster reduction management regulations, implement regular inspections of lightning protection facilities, inspections after lightning storms, and daily maintenance.

When designing and constructing lightning protection facilities, construction units should consider comprehensively factors such as geology, soil, meteorology, environment, characteristics of protected objects, and lightning activity laws, etc., and adopt safe and reliable, advanced technology, economic and reasonable design and construction.

Lightning protection equipment, devices, and equipment that conform to national standards in technology and quality should be used, and non-standard lightning protection products and devices should be avoided.

Re-design and construction of lightning protection system when newly added construction and newly added installation equipment applications.

When a lightning disaster occurs, the situation should be reported to the city lightning protection office in time, so that it can be dealt with in time to avoid another lightning strike.

Personal lightning protection methods: should stay indoors, and close doors and windows; people working outdoors should hide in buildings.

It is not advisable to use televisions, stereos and other electrical appliances without lightning protection measures or insufficient lightning protection measures, and it is not appropriate to use faucets.

Do not touch antennas, water pipes, barbed wire, metal doors and windows, external walls of buildings, and stay away from live equipment such as electric wires or other similar metal devices.

Reduce the use of telephones and mobile phones.

Do not swim or engage in other water sports, outdoor ball games are not suitable, leave the water and other open fields, and find a place to avoid.

Do not stand on the top of a mountain, on the top of a building or other objects close to high conductivity.

Never handle flammable materials contained in open containers.

When the wilderness cannot hide in a building with lightning protection facilities, it should be far away from trees and masts.

Umbrellas should not be used in open areas, and badminton, golf clubs, etc. should not be carried on the shoulders.

Motorcycles and bicycles are not suitable.

"5 · 23" accident caused thinking

Liu Xianhua, deputy director of the Department of Regulations of the China Meteorological Administration, said: The opening of the county has brought new thinking to the management of lightning protection.

One is that for building lightning protection codes, one or two or three building codes require the installation of lightning protection devices, but in the mountainous areas, some buildings are built on the mountain, so that its height also meets the requirements for lightning protection. Things have to be revised.
Another suggestion is about lightning protection. Previously, it was lightning protection against direct lightning strikes, but with the development of technology, especially electronic equipment, the problem of induction of lightning has also appeared. The second question is how to introduce regulations and standards in the current process of induction lightning protection, especially computer rooms like computers.

After the lightning strike accident occurred, the Chongqing Municipal Education Commission combined with the reality of the primary and secondary schools to effectively investigate and rectify the hidden danger of the lightning strike accident. In addition to teaching lightning protection knowledge to students in Chongqing, the education department also invited meteorological staff to educate teachers and students of each school on lightning protection safety knowledge. In terms of improving school facilities and equipment, the Chongqing Municipal Education Commission requires schools to purchase and improve equipment in accordance with fire safety regulations. The school must set up lightning protection belts and grounding down conductors for school buildings above four floors, water towers and flagpoles over 15 meters, metal water tanks installed on the roof, solar water heaters, satellite receivers, etc. First class lightning protection power protector. School computer room, voice room, electric classroom, network classroom, electronic reading room, broadcasting room and other power distribution entrances must be equipped with secondary lightning protection power protectors.

In addition to the lightning protection measures adopted by local governments and units, the pace of formulating relevant laws and regulations by the state also needs to be accelerated. It is understood that the current comprehensive management of lightning in China is under the China Meteorological Administration. As it is a departmental regulation, the level and effectiveness of the law are relatively low. Therefore, the relevant departments suggest that the state should formulate corresponding laws and regulations, and put the assessment of disasters in the laws and regulations, which is still necessary to strengthen the management of lightning protection.
