Life jackets, also known as personal flotation devices (PFDs) or life vests, are essential safety equipment designed to help keep individuals afloat in the water. They are primarily used to prevent drowning and provide buoyancy in emergency situations, especially for non-swimmers or in rough water conditions.

Life jackets are typically made of buoyant materials, such as foam or inflatable chambers, encased in durable and waterproof fabrics. They come in various sizes and designs to accommodate different body types and water activities. The main features of life jackets include adjustable straps or buckles to ensure a secure fit, reflective strips for increased visibility in low-light conditions, and a whistle or signaling device to attract attention in case of an emergency.

These safety devices are widely used in water sports, boating, fishing, and other aquatic activities where there is a risk of accidental immersion. They are essential on boats and ships as part of the safety equipment required by maritime regulations.

It is crucial to wear life jackets properly and ensure they are in good condition before engaging in any water-related activities. Regular maintenance, such as checking for tears or leaks and ensuring proper inflation in inflatable versions, is necessary to ensure their effectiveness. It play a vital role in promoting water safety and saving lives, making them an indispensable tool for anyone participating in water-based activities.
