Where are lightning prone in summer? How to prevent lightning stroke in thunderstorm days?

i. where is it easy to be struck by lightning

Generally speaking, lightning is easy to occur in the place where the soil resistivity is small and the soil resistivity changes obviously. Areas with metal deposits, river beds, groundwater outlets, hillsides and rice fields, hillsides and foothills, rivers, lakes, seashores, low-lying areas and places with high groundwater levels are all vulnerable to lightning strikes. Some isolated towers, chimneys and other tall buildings (structures) are also vulnerable to lightning. When thunderstorm comes, because the trees are tall, they are easy to be attacked by lightning. Stay away from trees in thunderstorm days, squat down as much as possible, and keep feet together.

Why the bathroom is a high incidence area of lightning

At home, most of the water pipes in the toilet are metal with strong conductivity, so the toilet naturally becomes a high incidence area of lightning stroke in thunderstorm days. Moreover, the vast majority of solar water heaters installed on the roof of the building are not connected with lightning protection equipment. Some solar water heaters are installed with high iron frame for good lighting. In case of thunder, the water heater may become a 'lightning starter', causing lightning stroke.

II. How to prevent electric shock

To prevent electric shock in severe weather, the following points should be noted:

1. In severe weather such as strong wind and thunderstorm, try to reduce going out. If you have to walk outside, you should carefully observe the terrain and road to avoid stepping on the wire. It is necessary to avoid walking around the electric facilities such as electric poles, towers, etc., and bypass the dropped wires.

2. Do not walk barefoot.

3. In case of thunderstorm and windy weather indoors, turn off the running household appliances in time and pull out the plug; do not go to repair the live lines or equipment in the home barehanded and barefoot; if you accidentally immerse in the water in the home, cut off the power supply immediately to prevent accidents of the household appliances in use due to water inflow and insulation damage.

4. When walking outside in rainy days, pay attention to observation, do not contact with the metal part of the road light pole, signal light pole and landing billboard, and bypass the place with water.

5. After finding that power facilities such as distribution boards and box type substations are flooded, when they are not close to other personnel, they should inform the power supply department in time to deal with them.

III. how to prevent lightning stroke in thunderstorm days

Some people think that as long as the building is equipped with lightning rod and lightning strip, people and equipment in the building 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 the lightning rod, it will not be protected by the lightning rod. Secondly, if the performance of the lightning rod meets the technical requirements, such as material specifications, grounding resistance, etc., if it loses its function due to long-term disrepair, it will not play a lightning protection effect, but will increase the probability of lightning stroke. Moreover, the lightning rod can only protect the building from lightning, but not the people and equipment inside the building from lightning. The lightning rod can only discharge 50% of the lightning energy to the ground, and the rest 50% of the energy will be discharged to the ground through various pipelines and equipment through induction and energy coupling.

IV. what to pay attention to when encountering strong thunder and lightning

In case of thunder and lightning, pay attention to the following points:

1. If you happen to be at home when there is strong thunder and lightning, it is recommended not to venture out. Do not use the radio and TV set with external antenna. Do not answer or make phone calls.

2. If you are in the field, you should find a shelter immediately, and use the buildings with lightning rod, steel frame or steel plate concrete as the lightning protection place, and the vehicles with complete metal carriage can also be used.

3. When there is no shelter, do not close to the open area or the isolated tree on the top of the mountain, which is the most vulnerable to lightning. Do not stay in open water and boats; try to avoid the edge of tall trees and forests, around electric wires and flagpoles, near tall objects without lightning protection equipment such as haystacks and tents, not close to railway tracks, long metal railings and other large metal objects, and do not stay in places such as mountain tops and commanding heights.

4. During lightning, it is better not to ride a horse, bicycle or motorcycle; do not carry metal objects to walk in the open air; do not close to any part of lightning protection equipment.

5. If you can't find a suitable lightning protection place, you should reduce the center of gravity and the contact area between the human body and the ground as much as possible. You can squat down, put your feet together, put your hands on your knees, and bend forward. Never lie on the ground, in the trenches or in the earth pits. If you can put on the raincoat, the lightning protection effect will be better. People in the wild, whether moving or stationary, should be kept away from each other for several meters. They should not be crowded together, but also hide in large caves.
