The most important thing to avoid drowning accidents is not to swim in the wild. Many people have a lucky mentality and enjoy swimming in the wild. Chen Gang, Deputy Branch Leader of the Patrol Detachment of the Water Branch of Chongqing Public Security Bureau, believes that this idea is extremely dangerous. Firstly, the water situation is complex and unpredictable. The depth and flow velocity of wild water bodies are often unknown, and there may be strong undercurrents or eddies hidden beneath calm water surfaces, which can easily wash people away. Unstable water temperature may also cause leg cramps, instantly rendering a person unable to swim. Secondly, the underwater environment is full of dangers. Sharp stones, glass, and tangled aquatic plants can all become 'underwater killers', causing injuries or trapping. Thirdly, there is a shortage of rescue forces. There is a lack of professional lifeguards and facilities near the wilderness waters, making rescue efforts often beyond reach. Finally, biological threats cannot be ignored, as snakes, leeches, and even aggressive fish can pose a threat to people in the water. When an accident occurs, the correct self rescue method can buy valuable time to save lives. Keeping calm is the first rule. ”Chen Gang told reporters that struggling in the water will exhaust one's physical strength within 3 minutes. At this time, one should immediately take off their shoes and try the "jellyfish float" position - tilt their head back, stretch their limbs naturally, and use the air in their lungs to keep their body floating on the water surface, ensuring breathing through their mouth and nose. If there are floating objects nearby, such as wooden boards, branches, etc., try to grab them as much as possible and use their buoyancy to keep the body on the water surface, increasing the chance of rescue. Do not attempt to land on your own unless you have sufficient swimming ability and physical strength to avoid danger during the process. ”Chen Gang said. When others are in danger, there are rules to follow when rescuing them. Non professionals should not rush into the water for rescue. They can call 120 or use tools such as bamboo poles and lifebuoys to carry out shore rescue. ”Chen Gang said, "After rescuing people, the first step is to remove foreign objects from the drowning person's mouth and nose, use the 'knee top method' to drain water, and perform cardiopulmonary resuscitation on those who have suffered cardiac arrest." "Acting wisely" is more important than "acting bravely". On May 25th, two junior high school students in Xinmin Town, Dianjiang County, Chongqing, accidentally fell into a river while on their way out of school. The two of them cooperated seamlessly. One jumped into the water from the steps at the bridgehead and grabbed the boy's collar, while the other pulled a long vine from the green belt and threw it to his companion. In less than 3 minutes, they successfully rescued the boy. (New Society)
