Water rescue - life jacket selection and wearing methods

How to choose a life jacket is crucial for emergency rescue workers. Here to talk about the choice of life jackets:

1. Fabric

There are two kinds of life jacket fabrics, one is: special nylon material, this kind of fabric is relatively cheap, use a wide range, but not durable;

The other is: NEOPRENE neoprene (dive material), this fabric is more expensive, soft and comfortable to handle, and resistant to friction, as long as the higher-grade life jackets are used.

2. Lining

There are two kinds of life jacket linings (buoyancy objects). One is: Polyethylene foam. This kind of lining material has a relatively low price, ample buoyancy, and a wide range of uses. However, the buoyancy that is subjected to buoyancy will be immersed in the water. The change is around 5% .

The other is: using ultra-lightweight super-buoyant EPE pearl cotton, this lining material is significantly more expensive than foam, its obvious advantages. Strong buoyancy, life jackets are easy to fold, easy to dry, and more importantly, they are immersed in water for a long time and the buoyancy is reduced significantly.

3. Reinforcement

There are two methods used for reinforcement of life jackets. The first kind: ropes, such life jackets are generally low life jackets. This is used more often in early life jacket designs.

The second is zipper + breasted, this life jacket is now the most widely used one.

4. Accessories

There are two kinds of life jacket accessories commonly used, one is survival whistle, which is now basically standard life jackets;

The other kind is reflective film. If it is at sea and visibility is low, Xiao Bian is strongly recommended to be standard.

Here is a new life jacket recommended:

GRS Automatic Inflatable Life Jacket

Automatic inflatable life jackets are mainly composed of airbags, small high-pressure gas cylinders, and automatic inflation valves. They are suitable for use at sea and waterside activities. Under normal circumstances (not inflated), the entire inflatable life jacket is worn like a harness on the person's body. This product is light and compact, and does not impede work when worn. It overcomes the bulky, stuffy, and other undesirable features of traditional foam life jackets. Once in the water, the airbag is automatically inflated and inflated in 5 seconds into a life jacket with a buoyancy of 16 kg ( SY-A150 ) or more so that the head and shoulders of the person can float to the surface to provide safety protection. Under special circumstances, when the wearer falls into a coma, it has the function of self-righting and entering the water, so that the head can be kept upturned and can provide the best safety and rescue.

Life jacket wear step

Step 1: Put the lifejacket on the neck and place the square buoyancy blocks on the chest (Note: The lifejacket is facing forward and backward, the name of the boat is facing forward, and the double side with reflective tape is to face outward, otherwise the reflective tape Do not work, then tie the straps on the neck (Note: Department of death).

Step 2: Tighten the straps down and cross them back.

Step 3: Pull the strap to the front and fasten it through the buckle strap (Note : the buckle is dead)

Step 4: Make a good check on each other.
