1. Do not go out swimming alone, and do not go swimming in places that do not know the bottom and water conditions or are dangerous and suitable for drowning accidents. Choose a good swimming place, and understand the environment of the place, such as whether the reservoir and bathing place are sanitary, whether the underwater is flat, whether there are reefs, undercurrents, weeds, and the depth of the water area.
2. Must be organized and under the guidance of teachers or people familiar with water to swim. So as to take care of each other. If the collective organization goes out for swimming, the number of people shall be counted before and after entering the water, and lifeguards shall be designated for safety protection.
3. You should be clear about your physical health. People who are prone to cramps in their limbs should not participate in swimming or swim in deep water. To get ready for the water, you should first move your body. If the water temperature is too low, you should first bathe your body in shallow water, and then swim in the water after you get used to the water temperature.
4. You should be self aware of your own water quality. You should not show off your ability after entering the water. You should not dive and snorkel rashly. You should not fight with each other to avoid drinking and drowning. Don't swim in rapids and whirlpools, and don't swim after drinking.
