Buoyancy is the ability that prevents the object from drowning. In other words, it s a force that makes the object float over the suface of the water. It contains foam like material that is used in the displacement of the water. Then in turn the water puts an upward force over it beacuse of which it comes out on the surface floating. Such buoyant materials are usually found in the PFDs (Personal Flotation Devices) or what are commonly known as life jackets. They are the primary forces that work in the life jackets. It is because of their presence that life jackets serve their functions properly. When they touch the surface of the water, only then they start their work. Based on the buoyant material, they buoyancy of the PFDs or life jackets can vary and that variation determines their function. Therefore, it is crucial to check the buoyancy of your PFD before diving dirrctly into the deep water.
- Ways to check the Buoyancy of the PFD / life jacket:
The ways in which the buoyancy of the Personal Flotation Devices can be checked is divided into a number of steps. These steps are described as following:
- First of all, the PFD must be worn.
- It should be make sure that the life jacket fits one properly. It must not be too fit to restrict the movements of the person. A person must be really comfortable while wearing a personal flotation device
- Look for a shallow water When one has to test the buoyancy of the life jacket, one must not dive directly in the deep waters rather look for a water that can easily be taken care of i.e. a swimming pool etc. A swimming pool is the best place to check the buoyancy of the life jacket.
- While getting into the water, one must take someone with him. Even if the water is shallow, still someone can be needed in case if the PFD (Personal Flotation Device) does not work as intended. So the other person must stand nearby and notice.
- Then slowly enter into the water. Make sure not to rush things.
- Float on your back- it is the most recommended way to try. Then relax yourself and let the water and the life jacket do their work.
- Then notice if your head and chin are above the water surface so that you can breathe easily. There must not be any hindrance in the breathing process and everything should go smoothly.
- After this, come out of the water and notice the life jacket/ PFD properly. Look for any pores if there are. It will allow you to know more about the quality of your life jacket i.e. whether it gets damaged after getting into the water or not. If it does get damaged then it must be replaced and such PFDs must never be taken for diving into the deep waters.
- Conclusion:
A PFD’s buoyancy must be checked before taking it to deep waters. The quality should be checked and only the best material should be taken for safe swimming.
