How to prevent lightning strike when riding a motorcycle in rainy days?

In the folklore of China, lightning is regarded as a force to safeguard justice, and only when a person does evil can he be struck by lightning. Of course, now we know that lightning doesn't shock people because they are good or evil. When lightning strikes any building or its vicinity, it will seriously damage the electrical equipment in the building and even threaten people's lives.

The harm of lightning can be divided into direct lightning strike and indirect lightning strike. Direct lightning refers to the conduction between the discharge of buildings or other surface objects and the Lei Yun, and huge current flows at the struck place, thus producing huge electric effect, thermal effect and electromagnetic effect. And destroy the object that was hit. After lightning strikes a certain place, the electromagnetic waves aroused will spread outward, destroying or affecting nearby electrical equipment. The high potential generated after lightning strike will also enter the nearby buildings along the nearby wires, damaging the electrical appliances connected with it. So how to prevent the occurrence of lightning disasters? According to the nature and importance of buildings, it is the basic part of lightning protection to install lightning protection facilities in various buildings. When it is necessary to connect wires between buildings or establish communication and television links at ordinary times, the wires should be buried underground to prevent the introduction of indirect lightning. When it thunders, you should turn off the electrical appliances and disconnect the external power supply. When encountering a thunderstorm in the wild, you can't run under a big tree to shelter from the rain, because the big tree protrudes from the ground and is easily hit by lightning. You can find places or caves with lightning protection measures. If you can't find them, try to reduce the center of gravity and the contact area between the human body and the ground. You can squat down, put your feet together, put your hands on your knees and bend forward. If you wear a raincoat, the lightning protection effect will be better. Don't lie on the ground, in trenches or in pits. In particular, you should try to avoid answering your cell phone in thunderstorm weather, especially when you are traveling outside and in an open place. Be sure to turn off your cell phone in thunderstorm weather.

Where are you vulnerable to lightning?

Generally speaking, places with low soil resistivity and obvious changes in soil resistivity are prone to lightning strikes. Areas with metal deposits, river beds, underground outlets, hillsides bordering rice fields, hillsides and foothills, rivers, lakes, coasts, low-lying areas and places with high groundwater levels are all vulnerable to lightning strikes. Some isolated tall buildings (structures) such as iron towers and chimneys are also vulnerable to lightning strikes. When a thunderstorm comes, because the trees are taller, they are vulnerable to lightning. Stay away from trees in thunderstorm weather, and try to squat down with your feet together.

Why does the bathroom become a lightning strike area?

At home, the water pipes in the bathroom are mostly metal bodies with strong conductivity, so in a thunderstorm, the bathroom naturally becomes a lightning-prone area in the home. Moreover, the solar water heaters installed on the roofs of most citizens are not connected with lightning protection equipment. Some solar water heaters are equipped with high iron frames for good lighting. In the case of thunder, the water heater may become a "lightning rod", causing lightning strikes.

How to prevent electric shock accidents

In bad weather, the following points should be paid attention to to to prevent electric shock:

1. In severe weather such as strong winds and thunderstorms, it is necessary to minimize going out. If you have to go out and walk, observe the terrain carefully, walk carefully and avoid stepping on wires. Avoid walking around power facilities such as telephone poles and iron towers, and bypass fallen wires.

Don't walk barefoot when going out.

3. indoors, in case of thunderstorm and windy weather, turn off the running household appliances in time and unplug the power supply; Don't go barefoot to repair live lines or equipment at home; If the home is accidentally flooded, the power supply should be cut off immediately to prevent the household appliances being used from accidents due to water ingress and insulation damage.

4. When walking outdoors in rainy days, pay attention to observation, and don't touch the metal parts of street lamp poles, signal lamp poles and landing billboards. Where there is water, we should go around.

5. After discovering that power facilities such as distribution panels and box-type substations are flooded, it is necessary to inform the power supply department in time and handle them without other personnel approaching.

How to give first aid after being struck by lightning

After being struck by lightning, you can take the following measures for first aid:

1. The injured person lies flat, unbuttoning buttons, belts, etc.

2. Immediately perform mouth-to-mouth resuscitation and chest compressions until the patient wakes up.

3. Holding hands or acupoints, such as Renzhong, Xuan Shi, Yongquan and Mingmen.

4. Send to the hospital for emergency treatment.

Don't shelter from the rain under the tree during a thunderstorm.

Don't go into the hut during a thunderstorm.

Don't overload the power cord.

Don't wipe the lamp holder with wet hands and wet cloth.

The air is humid in thunderstorm season, which is the season of frequent electric shock accidents. The public should replace the old or damaged wires in time to prevent accidents such as upside down and leakage that harm personal safety. Relevant experts answered questions about lightning protection, prevention of accidental electric shock, safe use of electricity, electric shock first aid and other knowledge.

How to prevent lightning strike in thunderstorm days

Some people think that as long as lightning rods and lightning belts are installed in buildings, people and equipment in buildings will not be struck by lightning.

This view is wrong. First of all, the lightning rod has a certain protection range. When the building is beyond the protection range of lightning rod, it is not protected by lightning rod. Secondly, whether the performance of lightning rod meets the technical requirements, such as material specifications and grounding resistance. If it loses its function due to disrepair, it will not only fail to achieve the lightning protection effect, but will increase the probability of being struck by lightning. Furthermore, lightning rods can only protect buildings from lightning strikes, but not people and equipment in buildings from lightning strikes. Lightning rods can only release 50% of the lightning energy into the ground, and the remaining 50% of the energy will be released into the ground through various pipelines and equipment through induction and energy coupling.
