in April 13th, a fire accident caused by lightning strikes at the top of the Shanghai Oriental Pearl Tower was caused by a lightning strike, and a district in the provincial capital was posted after two days. A notice came out that he was a "key hit area". Is it true? Or is the property making excuses to prevent residents from installing solar energy on rooftops? Experts say that Ji'nan does have such a wide range.
Community posted a notice that it was the focus of the residents of the mine area to see the half doubt
"I heard that the Oriental Pearl has just been struck by thunder, I did not think that the district has become a key mine area." On the morning of 15, Ms. Chen, who lived in a residential area near the Second Ring South Road, found a "notice" in the entrance of the unit. It said that the hospital was the key mine area in Ji'nan. No one could install solar, clothes hangers and TV satellite antennas on the top floor of the dormitory, such as dismantling and dismantling. All the consequences are conceited. The payment is the Department of administrative affairs.
"will the property be designed to prevent people from trying to frighten people? What is the key mine area? If it is, will it be dangerous to live in such a place? " Although Ms. Chen is somewhat skeptical about the "key areas", there are still some concerns.
the afternoon of 15, the reporter dialed the telephone of the Department of administrative affairs of the hospital. A staff member who claimed to be a property explained that the "key mine area" was told by the relevant lightning protection units in the province. In 2004, when the residential area was just checked in, the elevator was actually broken down by the lightning strike. It is required to remove all the solar energy and clothes hangers installed on the roof, and the residents are more cooperative.
"now this notice is posted again, mainly because No. 1 and No. 4 are new occupants, afraid not to know this situation, but also to the summer of thunderstorm days, give everyone a wake up." The staff said.
in fact, Ji'nan really has such a region, and the scope is very large, but people do not need to worry about
what is the focus of the mine area? Is there such a region in Ji'nan? Yu Zhenbo, senior engineer of the Shandong lightning protection technology center, explained that the area of the thunderstorm is very large each time, and the so-called "key mine area" is only relative.
"mainly according to the history of lightning accident statistics, as well as the local terrain, geology, and so on, Ji'nan, from the ten road south to the south mountain area belong to such a region, there is no obvious boundary, the heroic mountain road to the Yanshan interchange is more serious." Yu Zhenbo said that people might think it was very large, but it was only a small point on the map of the professional lightning monitoring, and the east side of Jigang was prone to lightning accidents because of the underground iron ore.
Yu Zhenbo thought the area of the notice was indeed in this multi ray area, but it was not absolutely impossible to install solar energy in these places, as long as it was equipped with corresponding lightning protection measures, and no solar energy was not a problem in thunderstorm days.
thunderstorm season is coming, some small common sense is still to pay attention to the thunderstorm day better do not use the Internet
"generally May to September is the season of thunder, of which July is the peak." Yu Zhenbo said that in recent years, the increase in electrical appliances, the resulting accidents are also rising, according to incomplete statistics, the province has one thousand or two thousand every year, the death of the accident in the past few years sixty or seventy people dropped to more than a dozen people. "This statistic should be very incomplete. Most people will not report lightning accidents."
in addition, the vibro wave indicates that the higher the floor is easier to be misunderstood in the lightning strike. It is usually safer in the room, because the newly built buildings are generally accepted by lightning protection measures, but it is not good to distinguish which buildings in Ji'nan meet the standards. The key thunder area is only relative, no matter which area should pay attention to some common sense of lightning protection, do a good job of self protection. "Do not make landline phone calls, surf the Internet, take the elevator, use solar water heaters to bathe." As to whether or not to play a mobile phone is safe, Yu Zhenbo said that it is still uncertain.
