How to avoid thunderstorms when walking on the road in thunderstorm weather?

When it thunders and rains, it is forbidden to stay at the top of the mountain or in hilly areas. More importantly, it is forbidden to continue climbing to see the rain. You shouldn't hide under a big tree or near a telephone pole, nor should you walk or stand in an open field. You should hide in a low-lying place as soon as possible, or try to find a room floor or a dry cave to hide. ?

In thunderstorm weather, don't use an umbrella with a metal handle. Take off glasses, watches and belts with metal frames. If you travel by bike, you should leave the bike as soon as possible and stay away from other metal objects to avoid being struck by lightning. ?

Don't go swimming, boating and fishing in rivers and lakes in thunderstorm weather. ?

When it is thunderous and stormy, visitors should immediately turn off the indoor TV, tape recorder, stereo, air conditioner and other electrical appliances to avoid using electricity if they rest in the hotel. It's safer in the middle of the room when it thunders. Don't stay under the electric light, and don't lean against posts, walls, doors and windows, so as to avoid accidents caused by induced electricity when it thunders.

Explanation:

Lightning protection refers to avoiding the harm of lightning to human body and buildings through certain methods and measures.

Lightning protection misunderstanding:

First of all, it should be explained that the word "lightning protection" is wrong and a misunderstanding in modern lightning protection technology. At least in modern science and technology, lightning protection cannot be truly achieved. Although scientists can change the formation time and lightning strike point of lightning by means of laser and rocket, it is limited to scientific research and cannot be widely used at present.

Lightning protection measures:

External lightning protection measures mainly include the installation of lightning arresters (such as lightning rods, lightning belts, lightning protection networks, etc.). ), down lead and grounding device. The lightning receiver is used to intercept lightning and prevent the protected object from being directly hit by lightning; Grounding device is used to disperse lightning flowing to the earth, and has the requirement of grounding resistance; The down conductor is used to connect the lightning receptor and the grounding device.

Internal lightning protection measures include: shielding, reasonable wiring, installation of lightning arrester (SPD), equipotential bonding and grounding. Shielding and reasonable wiring can reduce the influence of electrostatic induction and electromagnetic induction on lines and equipment; Installing lightning arrester can limit the surge voltage on the line and guide the discharge of lightning current; Equipotential bonding can avoid the counterattack between adjacent metal objects and lines; Grounding is an important guarantee for shielding and lightning arrester to play its role.
