How to avoid lightning disaster

The methods to avoid lightning disasters are as follows:

1. Lightning protection device is installed on the building. That is, lightning protection devices are used to introduce lightning current into the earth and then disappear.

2. During a thunderstorm, people should not go near high-voltage distribution rooms, high-voltage wires and isolated tall buildings, chimneys, poles, trees, flagpoles, etc. Don't stand in an empty highland or under a big tree to shelter from the rain.

3. You can't use umbrellas with metal columns. Do not use metal tools, such as crowbars, when working in the suburbs or in the open air.

4. Don't wear wet clothes near or stand on metal objects in the open air.

Lightning disaster:

Lightning disaster is a meteorological disaster. The casualties and fires of people or animals caused by direct lightning stroke, as well as the faults or failures of electronic information systems such as power system, communication system and radar antenna caused by lightning wave intrusion and lightning electromagnetic pulse interference, are collectively called lightning disasters.

Characteristics of lightning disaster in China;

In addition to the characteristics of strong suddenness, frequent occurrence, wide range, long lightning activity period and many lightning fires, lightning disasters in China also have the typical characteristics of many deaths in rural areas and great economic losses in cities. At the same time, lightning disaster will cause power and information system paralysis and other hazards.

Causes of lightning disaster in China;

1, the influence of climate on lightning disaster.

China is located in temperate zone and subtropical zone, which is influenced by cold and warm air and land-sea interaction. Strong convective weather often leads to frequent lightning and thunderstorm activities.

2. The influence of topographic relief on lightning disaster.

Warm and humid airflow is easily generated by mountain uplift, which is beneficial to the formation of thunderstorm clouds. High altitude areas are more vulnerable to lightning strikes than low altitude areas.

3. Vulnerability of disaster-bearing bodies.

From the perspective of disaster science, the vulnerability of disaster-bearing bodies refers to the degree of injury or loss to all people, things and property that may be threatened by lightning disasters. The more concentrated the population and property in an area, the higher the vulnerability, the greater the risk of being struck by lightning, and the greater the potential losses that may be suffered.

For example, lightning current with the same intensity will have different consequences when it hits buildings with perfect lightning protection devices and buildings without lightning protection facilities at all.
