Extending the service life of water life-saving supplies is the key to ensuring that they can play an effective role at critical moments. Since water life-saving supplies are usually used in aquatic environments and are easily affected by multiple factors such as ultraviolet rays, salt water, and chlorine water, proper care and maintenance are essential. Here are some suggestions to extend the service life of water life-saving supplies:

1. Regular inspection and maintenance
Check materials and structure: Regularly check the structure and materials of life jackets, lifebuoys, lifeboats and other supplies to ensure that there is no wear, cracks or damage. In particular, the inflation system and zippers, buttons and other parts of the life jacket need special attention to ensure that they can be used normally in an emergency.
Check buoyancy and air tightness: For inflatable life-saving supplies (such as inflatable life jackets and inflatable lifeboats), it is crucial to check their air tightness. Inflate these devices regularly and check for leaks. Leaks can be checked by testing with water or applying soapy water to see if bubbles are generated.

2. Cleaning and Drying
Cleaning: After use, clean water life-saving equipment thoroughly with clean water immediately, especially equipment that has been in contact with salt water or chlorine water. Chemicals in salt water and chlorine water can accelerate the aging of materials, causing damage or corrosion. Therefore, cleaning with clean water can prevent the accumulation of salt or chemicals and extend the service life.
Drying: After using water life-saving equipment, dry it in time. Avoid stacking wet equipment in a humid environment for a long time, especially inflatable life-saving equipment. If life-saving equipment is wet for a long time, it is easy to cause the material to deform, mold or have odor.
Avoid exposure: Although the equipment needs to be dried, avoid direct exposure to sunlight. Ultraviolet rays can cause accelerated aging of materials, especially materials such as plastics and nylon. It is best to dry the equipment in a cool and ventilated place to avoid exposure to sunlight.

3. Proper storage
Avoid exposure to extreme environments: When storing water life-saving equipment, avoid exposing them to extreme temperatures, humidity or sunlight. High temperature and humid environment can cause material aging, deformation, fading, and even reduce buoyancy. Therefore, it is best to store lifesaving equipment in a dry, cool and temperature-appropriate place.
Avoid heavy pressure and squeezing: Do not place water lifesaving equipment under heavy objects or in squeezing places, which will cause the shape of the equipment to be damaged, especially inflatable equipment is easy to deform, affecting its use effect. When storing, you can lay life jackets or floats flat or hang them up to avoid any pressure that may cause deformation.
Check the storage situation regularly: Even if water lifesaving equipment is not often used, the humidity and temperature changes in the storage environment may affect their materials. Check the stored equipment regularly to ensure that there are no problems such as moisture, mildew or damage.

4. Avoid contact with sharp objects
Water lifesaving equipment, especially life jackets, inflatable lifeboats and floats, may be damaged by contact with sharp objects. During use, avoid contact with sharp objects such as stones, glass, metal, etc., especially when swimming, drifting or doing other water activities in the water.
If you accidentally damage the water lifesaving equipment, it is very important to repair it in time. Many inflatable equipment comes with a repair kit, which can be used to make small repairs to prevent further damage.

5. Avoid long-term storage in a humid environment
For water life-saving products after use, make sure they are completely dry before storage. Avoid storing them in a humid environment, such as a basement or a damp storage room. Long-term exposure to a humid environment may cause mold, corrosion, or even deformation of life-saving products, thereby shortening their service life.

6. Avoid excessive use
Water life-saving products, especially inflatable equipment, such as inflatable life jackets, inflatable boats, etc., will accelerate their wear and tear due to long-term high-intensity use. Therefore, during use, avoid excessive pulling or frequent inflation and deflation, and try to avoid unnecessary high-intensity use.
For equipment that needs to be exposed to the sun for a long time, try to choose equipment with UV protection, or block the sun when not in use. Frequent exposure to the sun will accelerate the aging and fading of the material.

7. Regular replacement
Although the service life of water life-saving products can be extended through care and maintenance, aging of materials and degradation of performance over time are inevitable. Therefore, it is necessary to regularly replace water life-saving products, especially some important safety equipment such as life jackets and inflatable lifeboats. If the buoyancy of these devices is found to be reduced or there are other safety hazards, they should be replaced immediately to ensure that they can play the greatest protective role in an emergency.

Conclusion
Extending the service life of water life-saving equipment can not only save costs, but also ensure the best safety protection during water activities. The service life of water life-saving equipment can be effectively extended by regular inspection, cleaning, drying, proper storage and avoiding contact with sharp objects. However, regular replacement of expired or damaged equipment is also the key to ensuring safety. Reasonable maintenance and timely replacement are important measures to protect the safety of yourself and others.
