Safety of drowning in winter

It is in the middle of winter, affected by cold air, and the temperature is low, which leads to the freezing of rivers, ditches, lakes and other places. It is extremely dangerous to move on the ice, which can easily lead to the collapse of the ice and drowning accidents.

1. The ice surface is smooth and fragile, and the ice water is cold. Once you accidentally fall into the ice hole, it is very difficult to rescue.

2. The bearing capacity of the ice surface is invisible to the naked eye. When you put out your foot to test whether the ice is solid, you are actually joking with your life.

3. In early winter and early spring, because the ice has not frozen or has begun to melt, people are easy to break when walking, running or sliding on the ice, which leads to danger. If the ice surface is covered with snow, it is impossible to judge the ice surface.

4. On the frozen ice surface of the flowing river, because the water level of the river will change with the change of water quantity, a "vacuum" of 2 ~ 3 cm will be formed under the ice surface. The aquatic plants and ice on the shore are mixed together, and the seemingly solid ice actually hides danger.
