How to choose a life jacket
1. Look at the fabric
Life jacket There are generally two kinds of fabrics, 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, It feels soft and comfortable, and is resistant to friction, which is only used in higher-end life jackets.
2. Look at accessories
There are two commonly used life jacket accessories, one is the survival whistle, which is One is basically a life jacket now, and the other is a reflective sheet. If you are working at sea and the visibility is low, we strongly recommend it. If it is general entertainment, it is generally not worthy. Ji Diao’s life jacket also has many additional functions, such as pockets, pliers bags, sub-line bags and so on. But there are some essentials for life jackets. No matter how the style changes, these are indispensable. These are the life jackets and safety belt
 s (pass through the straps connected to the front piece from under the back of the life jacket).
3. Look at the buoyancy
The buoyancy of the lifejacket should reach the specified standard (the buoyancy should not be less than 0.75kg after continuous immersion in seawater for 24 hours. The buoyancy of the front and rear pieces of the lifejacket should be in the correct ratio. ( Generally, the buoyancy of the front piece must be greater than that of the back piece. If the buoyancy of the life jacket is regarded as 1, the buoyancy of the front piece should be greater than 0.58.) There are generally two kinds of life jacket linings (that is, buoyancy), one is: polyethylene foam, which is The price of the lining is relatively low, the buoyancy is sufficient, and it is widely used, but the buoyancy it bears will change by about 5 percent with the time of immersion in water. The other is: the use of ultra-light and super-buoyant EPE pearl cotton. The price of lining is obviously more expensive than that of foam plastic, and its advantages are obvious: strong buoyancy, easy to fold and fold the life jacket, easy to dry, and more importantly, the buoyancy is immersed in water for a long time, and the buoyancy is reduced significantly less.
4. Look at the reinforcement situation
There are two commonly used methods for reinforcement of life jackets. The first one: rope, this kind of life jacket is generally a low-profile life jacket. This is in the early days There are many life jacket designs. The second is zipper + button, which is the most widely used one now.
5. Look at the color
In order to easily find the drowning person in the sea, the fabric color of the life jacket is generally brighter, and there are reflectors on the shoulders of the life jacket, which should be paid attention to when purchasing.
The above is the answer to how to buy a life jacket. I hope you can understand these five key points in detail, and better apply them to real life. At the same time, I hope everyone can pay attention to personal safety and do not go into the water easily.
