Many people think that the roof of the building has been set up on the lightning rod, can ensure that all of our home appliances and equipment safe against lightning. In fact, this view is wrong. In fact, lightning rods can only prevent direct lightning, and can only form a protection for the building. It will also release a large number of induced lightning in the prevention of direct lightning, and the lightning rod release of induced lightning. The lightning rod will release the induction of lightning in the instant along the antenna, feeder, signal lines and power lines and other intrusion of electrical appliances, electrical appliances to bring great harm. Therefore, only lightning rod lightning protection is not enough, must add three-level lightning protection system. Three-level lightning protection system refers to the building's lightning protection system, the floor of the power lightning box and indoor lightning socket.
And some people are used to turning off their TVs and computers when lightning starts, thinking that this will ensure safety. In fact, this method can not protect the safety. As computers and other ultra-large-scale integrated circuits with unusually high sensitivity, even if there are computer facilities on the building installed lightning protection devices, lightning generated by electromagnetic induction and electrostatic induction, will still form a high-voltage shock wave, so that the electronic equipment is broken. Thunderstorms fall, it is best not to use the computer, just turn off the power supply of electrical appliances can not prevent lightning, because the ground is connected, lightning generated by the strong current is ultimately transmitted to the ground through the wires and electrical appliances, so just turn off the power supply of electrical appliances, or will be passed through the current and pass into the ground, so just turn off the power supply can not guarantee complete safety, only to unplug electrical appliances, completely withdrawn from the circuit in order to ensure the Safety. In addition, in the work or a lot of can not turn off the power of the case, to ensure the safety of electricity or need to choose a large anti-strike current power lightning socket.

If there is a lightning, indoor personnel lightning to do the four points: First, can not stay on the roof of the building (house). Most lightning strikes on buildings occur at the top of the building, especially in the countryside is more so. Second, be careful to close doors and windows. For the ball lightning activity is more frequent in the region, for the reinforced concrete frame structure of the building, generally close the doors and windows can prevent the intrusion of side-strike lightning and ball lightning. Third, should not use the shower shower. This is mainly because in case the building is struck directly by lightning, the huge lightning current will flow into the ground along the building's facade and water supply pipes, and the lightning current may flow along the water and lead to casualties from lightning strikes on the shower. At the same time, do not touch the water pipes, gas pipes and other metal pipes. Fourth, should not be close to the building's exterior walls and electrical equipment. A U.S. statistics reflect that there have been four people killed by lightning on the phone.
