In two days of gut-wrenching news, a ferry sank in the Tigris river near mosul, Iraq, killing 100 people. In the same two days, a Norwegian cruise ship was in distress, leaving more than 1,300 people stranded and eventually being rescued by helicopter, but all were eventually safely back on shore.
So many accidents at sea, how to rescue it? When a ship sinks, the crew sends out an alarm signal — a “seven short, one long” siren that goes on for a minute. When the ship is found to be sinking, it is necessary to calmly determine the cause and wait for rescue or evacuation in an orderly manner according to different situations. Ship on fire: on the upwind orderly evacuation, emergency abandon ship.
Two ships collide: leave the collision site to avoid extrusion, find a place to secure themselves to avoid falling injury, emergency abandon ship. Slow to sink: run to the deck as soon as possible and wait for rescue. If possible, collect survival essentials such as flashlights, signal lights, purified water, food, reflectors, first aid kits, etc., for further escape.
If you need to abandon the ship, you need to wear a life jacket or find a life buoy, keep calm and leave the ship according to the direction of the ship’s evacuation diagram. It is very important to keep calm at this time, because panic can easily lead to pushing, trampling, and injury to others. Studies show that 70 percent of injuries are caused by panic at sea. There are two possible ways to abandon a ship. You can leave on a raft, or you can jump out of a boat if you can’t wait to get on the raft.
Swim only a short distance in cold water. Do not attempt to swim to shore unless you have a life jacket/float or are close to an offshore or salvage vessel. When floating on the water, to use the hand of the communication equipment to send out a signal for help, flashlight and other luminescent goods to open, the reflector constantly irradiation, but also to the sea into the dye, and even issued a signal flare, burning clothing to attract the attention of other ships at sea, etc..
The first 24 hours from abandoning ship to the water should be spent avoiding food and drink to build endurance. Ration food on the life raft; Can not drink seawater, can collect rainwater to drink; Fish eyes, spinal cord also have fresh water, when necessary to eat.
Having said that, the most important thing is to have the most important soaking suit on board, the best and the worst, and then make up for it. Flooding insulation can play a big role; the wearer in 0 ~ 2 ℃ water temperature calm water, after 6 hours, hypothermia is not more than 2 ℃. Buoyancy 142N. After soaking in fresh water for 24 hours, its buoyancy loss < 5% will be soaked in running water for one hour, and the water content in clothes will not exceed 200g.
