What kind of harm will thunderstorms cause?

Thunderstorm weather often produces strong discharge phenomenon. If the discharge hits people, buildings or all kinds of equipment, it will often cause casualties and economic losses.

The harm of lightning to human body includes the direct action of current, overpressure or electric power and high temperature. When a person is struck by lightning, the current will pass through the human body quickly. In severe cases, it will lead to heartbeat, respiratory arrest and brain tissue hypoxia and death. In addition, when lightning strikes, sparks will be generated, which will also cause different degrees of skin burns.

Lightning injury can also cause dendritic lightning stripes, epidermal peeling, intradermal bleeding, eardrum or visceral rupture. China is a country with frequent natural disasters, and there are many lightning disasters in China, the most serious of which is in the south of Guangdong Province. The lightning natural disasters in Dongguan, Shenzhen and Huizhou have reached the highest in the world, and these places are also affected by the relatively low atmospheric position.

Measures to prevent danger:

1, pay attention to close doors and windows, and indoor personnel should stay away from doors and windows, water pipes, gas pipes and other metal objects. Turn off household appliances and unplug the power supply to prevent lightning from invading from the power cord. When you are outdoors, you should avoid it in time and don't stay in the open field. When there is nowhere to hide in the open field, try to find a low-lying place (such as a pit) to hide, or squat down immediately to reduce the height of your body.

2. Stay away from isolated trees, towers, telephone poles and billboards. Immediately stop outdoor swimming, boating, fishing and other water activities. If many people are outdoors, don't crowd each other to prevent the current from conducting to each other after being struck by lightning. If you encounter a floating "fireball", avoid it gently to avoid airflow. Don't touch it.
