         China Meteorological Administration requires the implementation of lightning protection safety supervision standards

    From April 1, 2018, the meteorological industry standards in the field of lightning protection safety supervision, such as the "Lightning Protection Safety Inspection Regulations", were officially implemented. Recently, the China Meteorological Administration issued a notice requesting the publicity and implementation of nine lightning protection safety standards. As an important part of the lightning protection safety supervision standard system, the promulgation and implementation of the nine standards are of great significance for further transforming the management methods of lightning protection and disaster reduction, and improving the post-event supervision capability and level.


    Lixia, the beginning of the summer, also reached the season of heavy rain and lightning in the year. To prevent lightning from starting around, therefore:


    First, outdoor lightning protection should pay attention to the following 5 points:


    1. Don't stay on top of the mountain, ridge or building.


    2. Do not stay near iron gates, iron fences, metal clothes ropes, overhead metal bodies, and railway tracks.


    3, should quickly fall into the building (structure) with lightning protection, or a variety of vehicles and ships with metal casings. If you do not have the above conditions, you should immediately close your feet and bend your head forward to lower your height to reduce the risk of step voltage. Because the lightning current will gradually release energy along the ground through the falling point. At this time, between the forefoot and the hind foot of the person walking, a certain voltage may be generated between the two steps due to the difference in potential difference.


    4, don't be in the big tree (in the wild, you can also rely on tall trees to protect against lightning, but remember to leave the trunk and leaves at least two meters away.), telephone poles, billboards, all kinds of towers under the rain . Because at this time, the damp branches of the big tree are equivalent to a lightning-leading device. If you touch the big tree, the electric pole, and the various types of towers by hand, as if holding the lightning protection device to lead the line, it is likely to be struck by lightning.


    5, do not stay at the water (river, river, lake, sea, pond, canal, etc.), swimming pool, squatting, to quickly go to the nearby dry housing to avoid thunderstorms.


    Second, indoor lightning protection should pay attention to the following three points:


    1. In the thunderstorm, try to avoid using household appliances and unplug the electrical power plug and signal plug.


    2. If there are conditions, install a lightning arrester at the power supply, and install a lightning arrester at the cable TV antenna, telephone, fax machine, computer modem modem entrance, satellite TV cable interface. However, you must have a good grounding wire during installation and make a grounding grid.


    3. Listen to the weather forecast every day. When you find that there is a thunderstorm on the day, you should unplug the power plug and signal plug of the household appliance before going to work, and don't forget to close the door and window when you go out to prevent the intrusion of the rolling ball.
