On the evening of June 1, a passenger ship that sailed from Nanjing to Chongqing sank in Jianli waters in the middle reaches of the Yangtze River. The accident caused 458 passengers to board the ship, including 406 domestic tourists, 5 travel agency staff, and 47 crew members. According to the People's Daily microblogging news, as of 15:10 on the 2nd, 19 people have been rescued, of which 14 survived. At present, the search and rescue work continues and the list of complete versions of wreck tourists has been announced.
Traveling by boat is an ancient but conventional way of transportation. Although shipwreck is a probable event, we still hope that in case of shipwreck, these first aid knowledge provided below can play a role and win more lives for individuals. The hope is for the family to reduce some of the sadness of heaven and earth.
1. When boarding: Investigate terrain and become familiar with lifesaving items
After boarding the passengers, do not rush to watch the scenery and place the luggage. You should first pay attention to the emergency signs on some of the ships, such as escape routes, going upstairs and downstairs, and deck rendezvous. Second, we must look at the location of some items, such as life jackets and lifebuoys.
These seemingly simple preparations are very useful in times of crisis. Because the space in the cabin is small, the corridors and the corridors look very similar. Once there is danger, and they are not familiar with the internal structure of the ship, it is easy to get lost in the cabin and unable to escape in time.
2. When the danger occurs: Obey the captain and do not jump the boat easily
In the end, if you do not jump, you should generally follow the captain’s command, because after all, his experience in the sea and his self-help experience are much richer than passengers. If a passenger blindly jumps into the sea, the human body's body temperature will be quickly lost, and the currents in the ocean are very complicated. After jumping into the sea, it is very likely that they will be taken away by ocean currents and disappear, increasing the difficulty of search.
If there is a last resort, you can consider several prerequisites: the first is whether the captain has instructions; the second is whether it is necessary to abandon the ship, such as the hull is about to overturn; the third is whether there is a rescue ship around the timely response. If one of the conditions is met, you can consider abandoning the boat.
3. After abandoning the boat: wear a life jacket to grasp the best time difference
In case of shipwreck, passengers should carefully listen to the evacuation broadcast on board the ship. If a signal of 7 short beeps is heard, it means that the ship is about to sink and the captain has to abandon the ship. At this time, there is usually a 1-2 hour difference between the sinking of the ship and the first time to find life-saving supplies (if there is no life jacket, you can wear a down jacket sweater, etc.) and after wearing it, quickly rush to the assembly point of the deck, because At the assembly point, there are usually lifeboats and other equipment to help escape. When you are escaping, you must use the whistle and reflective equipment on the life jacket to attract the attention of rescue workers.
4. Tips for Diving: Feeling away from the boat and feet together
If you unfortunately fall into the water, you must swim as far as possible, because there will be many things beside the boat. Too close will not only be involved but may also be injured by floating things; diving should also try to choose a lower position. It is estimated that if the height of the diving is more than 5 meters above the water surface, it will be dangerous due to the powerful impact force.
Jump to the water should take the best posture, feet close together, arms crossed chest, close to the life jacket, so that the head and neck exposed. After touching the water surface, it is extremely important to breathe hard before sinking. It is also the key to survival. When you sink, keep calm, close your lips, clench your teeth and hold your breath. Don't fight hard in the water.
5. How to stay longer in the water: "Jellyfish float" or use all floating tools
In the absence of life jackets and lifeboats, it is necessary to master some tips for lifesaving in water. If you can swim, you can take the most energy-saving "jellyfish drift." After inhaling, the body relaxes. When the face is down, the limbs hang down naturally. Like a jellyfish, it floats on the water. When you need to inhale, raise your hands up to the lower forehead and push the water outwards. The head comes out of the water. Breathe, then lower your head and breathe back in a jellyfish-like floating posture.
However, if it is a natural "dry duck", it is necessary to use the props to help themselves. If there are no floats such as planks, clothing, such as trousers, can be used. Blow the two legs into the air and tighten the outlet to prevent the air from leaking out. The trouser legs form the airbag. With the aid of the buoyancy of the airbag, it floats on the water and waits for rescue.
In addition, open boxes, buckets, basins, fuel tanks, etc. are also props that can be floated, and can be used to press the opening part under the water surface or seal it as a floating tool.
