You can squat down, put your feet together, put your hands on your knees, and bend forward. Don’t lie on the ground, in trenches or pits. If you can put on a raincoat, the lightning protection effect will be better. People in the wild, whether moving or stationary, should be separated by a few meters. They should not be crowded together. They can also hide in large caves. 6. note that when your hair is erect or your skin vibrates, lightning may strike and you should immediately fall to the ground.

Misunderstanding of lightning protection some people believe that as long as lightning rods and lightning strips 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 exceeds the protection range of the lightning rod, it will not be protected by the lightning rod. Secondly, whether the performance of the lightning rod meets the technical requirements, such as material specifications, grounding resistance, etc. if it loses its function due to disrepair for a long time, it will not play a lightning protection effect, but will increase the probability of lightning strike. Moreover, the lightning rod can only protect the building from lightning, but can not protect 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 remaining 50% of the energy will be discharged to the ground through various pipelines and equipment through induction and energy coupling
