In India, within 24 hours, 72 people have been killed by lightning in Uttar Pradesh, Rajasthan and Madhya Pradesh, and many others have been injured. In case of lightning, don't swim or engage in other water activities unless you take shelter under a tree; Enter the building with lightning protection device or the vehicle with metal ceiling as soon as possible to avoid entering; Do not be close to high-voltage wires, street lamps, billboards, etc.; It is not suitable for carrying umbrellas, fishing rods and other metal objects in the wild; Don't use the mobile phone.

if indoors, doors and windows should be closed to prevent spherical lightning from entering; Do not use solar shower equipment and electrical appliances, and avoid contact with metal pipes. Lightning protection of modern buildings is a systematic project, including lightning arrester, also known as lightning rod. The function of lightning rod is to guide lightning, that is, to attract the location of lightning to the lightning rod itself, and then the lightning rod is connected to the grounding device through the down lead, and then the current is discharged to the ground to ensure the safety of the building and some facilities in the building.

Some surge protectors will be installed in the building, and some electromagnetic shielding measures will be taken to protect some facilities and personnel in the building. Lightning protection refers to avoiding the harm of lightning to human body and buildings through certain methods and measures. Lightning is a natural discharge phenomenon. Lightning is a natural disaster, which not only damages equipment and housing facilities, but also may cause fire, explosion and even human and animal casualties. Lightning rod, lightning wire, lightning protection network, lightning protection belt and lightning arrester are often used as lightning protection devices. The whole lightning protection device includes lightning rod, down conductor and grounding device.

buildings without lightning rods or lightning protection devices are very dangerous. The top floor is relatively high, and it is vulnerable to lightning in thunderstorm weather. When there is a lightning protection device, the charge accumulated in the cloud will transmit the current to the ground through the conductor of the lightning protection device. If lightning strikes, the air will discharge to the building, and it will also be released to the ground through lightning rods and connecting wires. If there is no lightning protection device, the extremely high voltage will puncture most objects, and people and wires in the building will be in great danger. Lightning will instantly raise the temperature of surrounding objects and air, which is very likely to cause fire and explosion.
