So that in the event of a ship abandoning the ship, all occupants on the ship can use these lifesaving equipment to wait for rescue.
Types of life-saving equipment : lifeboats, liferafts, rescue boats, lifesaving buoys, lifebuoys, life jackets, throwing ropes, and life-saving pyrotechnic signals.

For cargo ships of 85 metres in length or less, the liferaft on each side of the ship has a total capacity of 100% of the total number of persons on board. If such liferafts cannot be quickly transferred to any one side of the landing water, additional liferafts should be provided so that the total available capacity on each side can accommodate 150% of the total number of persons on board.

4, the role of life jackets: can make the falling people upswing, keep the face, nose and mouth above the water without irrigation. Can reduce physical exertion, while reducing body heat loss.
Third, the life ring equipped
1. Purpose of use of lifebuoy: It is to help people who fall into the water, and to help people who fall into the water to rescue.
2. Manufacture: It is made in a ring shape with plastic or other materials approved by the Experience Boat Division. The foam that makes lifebuoys is closed-celled and is not affected by seawater and oils adversely affecting it at sea temperature or climate change. Can maintain its buoyancy and durability. The lifebuoy has canvas and handrails on the outside.
3, graphics: floating tires, handrails, reflective tape.
4. The lifebuoy is equipped according to the type of ship and the length of the hull - it cannot be said that it is equipped according to the structure of the ship.
Fourth, equipped with rescue buoys
1. The concept of lifesaving buoyancy: It is a rectangular or circular floating body made of steel air or foam plastic bag made of canvas or glass fiber reinforced plastic.
2, the use of purpose: for the victims to support it, floating on the water waiting for help.
3、Structural features: There are rope nets or movable plank foot in the floating body, which can be used by the victims. The outer side of the floating body should be provided with a hanging half-chained handrail cable that surrounds the entire buoyancy device. The handrail cable should be of a diameter that is not Synthetic fiber rope less than 10mm.
4. Equipped with rescue buoys: It is mainly configured on passenger ships sailing in the I-class navigation zone and is configured at 3% of the total number of seafarers and passengers.
4. Equipped with rescue buoys: It is mainly configured on passenger ships sailing in the I-class navigation area, and is configured according to 3% of the total number of seafarers and passengers. Pictured
Fifth, the life-saving signal with
1, equipped with requirements:
According to the "Code for the Survival of Life-saving Equipment for Sea-going Ships" published in 1983, the pyrotechnic signals to be provided by lifeboats and sampans in life-saving equipment of various ships are shown in the attached table.
According to the new provisions of the 83rd amendment to the 1974 International Convention, the number of red parachute rockets to be used in ocean-going ships (ie, A-type rafts) should be increased to four, and two additional orange-orange smokes should be added.
Lifeboats and boats should be equipped with pyrotechnic signals
Sixth, equipped with communication equipment
Equipment requirements:
1. All seagoing vessels should be provided with portable radios for lifeboats and rafts, and they should be kept in the cab or radio at ordinary times. When abandoning a ship for lifesaving, they should be carried by special personnel into the boat or raft as required by the deployment table.
2. For passenger ships on international voyages, if there are more than 199 persons on board but less than 1,500 people, there must be at least one mobile lifeboat equipped with a radio station. The radio is installed in a special cabin inside the boat, equipped with special battery power, and the engine of the boat. There should be a generator for recharging the battery.
