1. The life jacket filled with buoyancy material, that is, the fabric is made of nylon cloth or neoprene, and the buoyancy material is filled in the middle.
2. Inflatable life jacket: It is made of high-strength waterproof material, similar to the principle of inflatable lifebuoy or swimming ring. Divided into automatic inflatable or passive inflatable. But the most important thing for this kind of life jacket is: absolutely avoid sharp objects piercing or wearing the waterproof layer, which will cause unimaginable serious consequences after air leakage.

neck hanging

Before inflating, wear it like a vest. When falling into the water or in distress in the water, open the manual valve, inflate quickly in 5 seconds, and the human body is floated to the surface to save life. There is a mouthpiece on the life jacket, which can also blow air. When in distress, the manual valve is opened, the high-pressure gas of the cylinder is filled into the life jacket, and the front chest and back of the vest are rapidly inflated to form an air bag, which can generate 10 kg of buoyancy in the water to float the human body to the surface.

waist hanging
In leisure time, a webbing is fixed on the waist, and after accidentally falling into the water, it is inflated to form a horseshoe-shaped lifebuoy, which surrounds the waist of the drowning person, so that the drowning person floats on the water. The ready-made garments meet the requirements of the SOLAS Convention and the latest IMO specifications, and have been certified by CCS, and are allowed to be used in the fields of ship boundaries, ships, maritime anti-smuggling, water construction, water sports, salvage, pilotage, flood control, sea fishing and other fields.

fanny pack
The airbag before inflation is installed in a small bag and connected with the waist belt and tied around the waist. It does not hinder the normal operation of operators on the water and on board. After inflation, the airbag automatically pops out of the bag. Due to the connection of the buckle, the airbag drives the human body to float on the water surface. At this time, the airbag can be put over the head and placed on the neck and the chest with both hands. The buoyancy effect is similar to that of the inflatable life jacket. .
