On nine cold days, many rivers and lakes have frozen, and people often stay and play on the ice. The Municipal Emergency Management Bureau reminds the general public that due to large temperature fluctuations, uneven thickness of the ice surface, artificial excavation, etc., playing and walking on the ice surface is prone to danger.
Although it is four or nine years old, the flow of the river will melt the lower part of the ice, the ice layer becomes unevenly thick, and the ice layer that is repeatedly frozen and thawed is not strong. There are also people who dig ice caves on the ice to fish, and the ice caves are only a thin layer after being frozen at night, and it is likely to fall into the water when stepping on them.
On the ice surface, if a crack is found, it should be slowly lying down or lying down, crawling to the shore, or slowly rolling to the shore; if the ice surface is about to collapse, you should lie down or lie down, standing still and shouting for help. Once you encounter ice cracks and falls into the water, quickly grasp the items that can float at hand, and at the same time remove the heavy items on your body, do not flutter randomly, adjust the posture to make the body float as much as possible, and keep the head exposed to the water. Look for places with thick ice and small cracks, get your body as close to the edge as possible, put your hands on the ice, hit the water with your feet, make your body float, step on the ice in an ambush position, and slowly reach the shore and then go ashore by rolling or crawling.
