Instructions for lightning protection after the Beginning of Summer

After the Beginning of Summer, summer begins to arrive, and thunderstorms become more frequent. Lightning protection is particularly important in summer. What are the key points of lightning protection? Lightning protection instructions after the Beginning of Summer

If you are in the wild, you should find a shelter immediately. Reinforced concrete buildings equipped with lightning rods and steel frames are good places for lightning protection. Vehicles with complete metal carriages can also be used, but be careful not to get close to any part of the lightning protection equipment. When there is no shelter in the wild, do not get close to open areas or lone trees on mountain tops, which are most vulnerable to lightning strikes; do not stay in open water or on small boats; on the edge of tall woods, around wires, flagpoles, and haystacks. Do not stay near tall objects without lightning protection equipment such as tents. Stay away from railway tracks, long metal railings and other large metal objects, and avoid standing on mountain tops, commanding heights and other places.

If you happen to be at home, close the doors and windows; try not to use radios and TVs with external antennas, and do not make calls. At the same time, use computers, color TVs, stereos, DVD players and other weak current equipment at home. Stay away from exterior walls and it is best not to use these devices during lightning strikes. Even if you go out, it is best not to ride bicycles and motorcycles; do not carry metal objects while walking in the open air; and do not get close to any part of lightning protection equipment.

In addition, some office electrical equipment must also be protected against lightning, because the voltage resistance of general office electrical equipment can only reach tens of volts, and the maximum current that can pass through is only a dozen amps. When thunder strikes, a strong magnetic field will be generated in the air. During the discharge, the magnetic field will radiate outwards. The instantaneous current generated can reach tens of kiloamps or even hundreds of kiloamps, and the instantaneous voltage can reach tens of kilovolts or even hundreds of kilovolts. , electronic equipment cannot withstand such strong voltage and current.' If lightning enters the room along power lines, data lines, or other channels, it will cause destructive damage to equipment and even endanger people's lives.

Special reminder is that you should try to avoid making or receiving calls on your mobile phone during thunderstorms. Especially for tourists traveling in open areas, you must turn off your mobile phones during thunderstorms. Because after the mobile phone is powered on, the electromagnetic waves emitted can easily trigger induction lightning, turning the mobile phone into a lightning rod, which can easily cause tourists to be struck by lightning.
