Precautions for outdoor lightning protection

In midsummer, lightning weather is frequent. Do you feel scared when you look at the sky with dark clouds and thunder and lightning outside? Especially for babies, because they are still young and have no ability to distinguish between good and bad things, they need parents' care and tell them some safety knowledge. Mom and dad can't always be with their children and protect them completely, but knowledge exists in memory. So what are the safety precautions about lightning protection? Let's study together!

First of all, some children may be naughty. For those things that are more "scary" and "horrible", they will be challenged even more. Looking at the dark sky outside, they even want to go out to play. At this time, parents should warn their children not to go out to play in thunderstorm weather, but to stay at home and whether the doors and windows of light meals have been closed. If it is outdoors and it suddenly thunders and rains, tell them not to hide under the big tree. Because the ultra-wet branches of the tree have turned it into a lightning needle, hiding under the tree at this time can not only avoid the rain, but also pose a threat to life. Don't rush home, you can find other families and wait until the rain subsides.

Secondly, even indoors, cut off the power of all household appliances and stop dialing. Use your cell phone and turn it off. If you want to go out, don't take an umbrella made of metal, because metal is a conductive substance, which will attract lightning. When you go out in rainy days, wearing rubber shoes can play an insulating role.

Finally, one thing is not often noticed: at home, it is not appropriate to use showers and solar water heaters, because water pipes are connected with lightning protection and lightning will lead to water conduction and death, so if you want to take a bath, you can wait until the thunder is lower, or you can boil water yourself.
