In everyone's impression, don't stand on metal objects or big trees in lightning weather, otherwise the probability of being struck by lightning will rise directly. The venue for these people to dance square dance is very empty. Why are they also struck by lightning? In fact, in recent years, China has done a statistic and found that it is difficult to avoid being struck by lightning even in a relatively open place. Lightning strikes frequently occur in winter, accounting for 32% of the total data. In contrast, the incidence of lightning accidents in open places is much lower, but we should also take precautions.
Therefore, we can't simply think that it is enough to stand in an open place when it rains, or we should move indoors as soon as possible. Lightning is usually accompanied by heavy rain, so we should pay special attention. Never take an umbrella in lightning weather, because most umbrellas are made of metal, which may increase our risk. Be sure to stay away from trees, hilltops and roofs of tall buildings, because at this time, like lightning rods, they may be split and burned at any time and place, so it is best to stay away from trees for more than 5 meters.
If you are already at home, be sure to turn off the power, and remember not to make any phone calls casually, because electromagnetic waves may attract lightning strikes, so you can keep some emergency items around you, such as flashlights. In fact, if these square dancers had escaped earlier, perhaps such a tragedy would not have happened. Although physical exercise is a good thing, we should still put life safety in the position of 1.
