The most difficult part of salvage at sea is the search for difficulty because the majority of the human body is submerged by the sea, and it is difficult to find the target. Although the drowning person will wear a conspicuous orange life jacket, it can not be seen because of the long distance. If the person in the water doesn’t put a smoke bomb for lifesaving, it is difficult to find the rescue target whether from the air or from the sea. Secondly, the survival time at sea is short, which also brings some difficulty to the rescue. Therefore, the premise of waiting for others to help is to take the self-help measures as far as possible. The timely dispatch of distress signals is a prerequisite for the rescue because in this way valuable time can be gained for the rescue.
(1) The passenger ships are equipped with life jackets and life buoys, and the number of them is prepared according to the number of passengers. The belt of the life jacket must be securely fastened so as not to be washed away in the waves. The standard lifejacket is equipped with a life-saving whistle, and a quick whistling sound indicates a need for emergency assistance. The sea breeze often affects the speed of the rescue boat, so before the rescue crew arrives, the crew members will organize the passengers to wear the life jacket and wait for the rescue vessel on deck.
(2) In an emergency, the captain will order the ship to abandon the ship and release the lifeboat, and then organize the passengers to board the boat or life raft to escape.
After going onto the life raft, if you can't judge the prescription, don't row around in order to keep strength. You should stay where you are and wait for rescue workers. If you are in a situation where you have to abandon ship diving, you can't take off your clothes without a life jacket. Whether in hot summer or cold winter, your body should avoid direct contact with seawater.
(3) Add clothes as much as possible so that there is a layer of warm water between the body surface and wet clothes, which can prevent the warm water from exchanging heat with the surrounding cold water, thus helping to maintain the body temperature.
(4) When abandoning ship to dive, choose a side with a higher body and no holes, avoid floating objects in the water, and dive vertically into the water as far as possible. At the same time, we should also pay attention to protecting the mouth and nose to prevent the choking of water.
