When performing activities near the water, life jackets are vital to human life safety. How to choose a good life jacket is very necessary.
1. Look at the fabric
There are generally two kinds of life jacket rack 64 capacity, one is: special nylon material, which is relatively cheap and widely used, but not durable; the other is: NEOPRENE neoprene (diving material), which is more expensive , Feel soft and comfortable, resistant to friction, only higher-end life jackets will use this fabric.
2. Look at the accessories
There are two commonly used life jacket rack 48 capacity, one is survival whistle, which is basically equipped with life jackets nowadays, and the other is reflector. If you are working at sea and the visibility is low, we strongly recommend to use it as standard. If it is for general leisure and entertainment, it is generally unworthy. Jidiao’s life jacket also has many additional functions, such as pockets, pliers bags, strand bags, and so on. But there are some essential rescue life jacket, no matter how the style changes, these are indispensable, these are the life-saving pockets and safety belts (passing from the back of the life jacket through the strap that connects to the front piece).
3. Look at buoyancy
The buoyancy of the lifejacket should reach the specified standard (the buoyancy of the lifejacket should not be less than 0.75 kg when continuously immersed in sea water for 24 hours. The buoyancy of the front and back pieces of the lifejacket must have the correct ratio. (Generally, the buoyancy of the front piece must be greater than the The buoyancy is regarded as 1, and the buoyancy of the front piece should be greater than 0.58.) There are two general lifejacket linings (that is, buoyancy), one is: polyethylene foam, which is relatively inexpensive, has sufficient buoyancy, and has a wide range of applications. , But the buoyancy will change by about 5% with the immersion time in water. The other is: the use of ultra-light and super-buoyant EPE pearl cotton, the price of this lining is obviously more expensive than foam plastic, and its advantages are obvious 。The buoyancy is strong, the universal swift water rescue life jacket is easy to store and fold, easy to dry, and more importantly, the buoyancy is soaked in the water for a long time, the buoyancy is reduced significantly.
