In hot summer, many people like swimming. Due to the lack of common sense of swimming, drowning deaths occur from time to time. According to some regional statistics, the drowning mortality rate is 10% of the total number of accidental deaths. Therefore, don't go swimming alone, don't go swimming in places that don't know the water situation or are dangerous and prone to drowning accidents, and don't go swimming in rivers, lakes, reservoirs and other places without permission. Choose a good swimming place and have a clear understanding of the environment of the place. You can't swim here if there is a danger warning. Strictly observe the "four noes" when going out for swimming and bathing: 1, and don't go without the consent of parents and teachers; 2. Adults who can't swim can't accompany you; 3. Don't go to deep water; 4. Don't go to strange waters.

There are many thunderstorms in summer, so how to do self-prevention, meteorologists introduce some simple and effective prevention knowledge:

When it thunders, close the doors and windows first to prevent lightning from entering the house; Try not to use electrical appliances, it is best to unplug the power supply, and don't make phone calls, especially mobile phones. Pedestrians on the road should not approach isolated high-rise buildings, telephone poles, chimneys, corner eaves when sheltering from the rain, let alone stand in open highlands or under big trees to shelter from the rain.

If you are outdoors, you should look for shelter immediately. Such as concrete buildings with lightning rods, steel frames or steel plates; If you can't find a suitable lightning protection place, you should try to lower the center of gravity and reduce the contact area between the human body and the ground. Never lie on the ground, in a ditch or in a pit. If you wear a raincoat, the lightning protection effect will be better.

If you are in the wild, don't be close to open places or lonely trees on the top of the mountain. These places are most vulnerable to lightning strikes. Don't stay in open waters and boats; Don't stay near tall trees and forest edges, around wires and flagpoles, near tall objects without lightning protection measures such as haystacks and tents, and near huge metal objects such as railway tracks and long metal railings; In addition, people in the wild should be separated by several meters and should not be crowded together.

Note that when your hair stands up or your skin vibrates, you may be struck by lightning, so you should fall to the ground immediately. People who are struck by lightning may be burned or severely shocked, but they will not be prosecuted and can receive treatment safely.

If you happen to be at home during the thunderstorm, close the doors and windows. It is recommended not to venture out without special needs.
