Put the life jacket on the neck and put the rectangular buoyancy bag in front of you; fasten the belt of the neckline.

Life jackets have played a crucial role in water safety for centuries. Their evolution reflects advancements in materials, design, and safety standards. In this article, we explore the development history of life jackets and highlight key features of modern designs.

ZHENHUA specializes in the manufacture of self-inflating jackets for hand-held (hand), designed and manufactured in accordance with Europee jacket is inflated, use the protruding part of the cap to press the valve to test. The valve should be easily pressed. When it is released, it should be restored to the closed position and sealed again.
3. Appearance inspection of the outer cover and the webbing - check the outer cover cloth, seams, webbing connections, buckles, etc.; the fading of the cloth indicates that the strength is weakened, and the strength is checked by tightening the joint and the connecting portion. If the lifejacket has any damage, it needs to be replaced, and the test should be carried out before going out.
Fourth, storage
Store in a clean, cool, dry place.
Do not place soluble parts in an environment where humidity and temperature are too high for too long.
Dissolved parts of vented packaging cannot be stored in sealed containers when transported.
The storage time of soluble parts should not exceed 18 months before use.
How to test your life jacket
1. Put on a life jacket (exhaust state) into the shallow water area (water depth should be enough to keep your head above the water).
2. The automatic inflator will act and then inflate.
3. Tilt your head backwards to see if the air-filled life jacket can lift you up (the back is slightly tilted back) in a relaxed state of floating to see if your mouth is just above the water.
4. Repeat these steps, the life jacket is blown inflated, and the life jacket is partially inflated so that you can be adequately supported to complete the inflation. Note: Auto-inflatable life jackets are not recommended for those who are weak or not swimming.
5. Remove, vent, cool and reinstall according to the manufacturer's instructions.

Swimming with a life jacket is ideal for those learning how to swim or individuals swimming in lakes, oceans and rivers, since swimming in these areas can be more dangerous than swimming in a pool. A life jacket can protect you from waves and rapid currents as well as keep you safe if you become fatigued. Due to the bulkiness of a life jacket, you will need to ensure a proper fit of the life jacket before attempting to swim. While swimming with a life jacket you can opt to use your arms, legs or both.

Safety clothing is the safety protective clothing that people respond to various harmful factors in the environment during the production process. Therefore, the model, style and performance of safety protective clothing will all affect the important factors of its safety performance. Therefore, the scientific and reasonable design of protective clothing has become an important part of safe production.

Marine Lifejacket, (MarineChildLifejacket), suitable for life-saving use of all types of people on ocean coasts and inland rivers. The buoyancy of the lifejacket is greater than 113N after being immersed in the water for 24 hours, and the loss of buoyancy of the lifejacket should be less than 5%. Life jacket buoyancy material: polyethylene foam. The new marine life jacket is a new life jacket designed and manufactured in accordance with the requirements of IMOMSC207 (81) and MSC200 (80). The specification was implemented on July 1, 2010.
