life jacket

A life jacket is a wearable device designed to keep a person afloat in water, providing buoyancy to prevent drowning. Made from lightweight, buoyant materials like foam, it fits securely around the torso and often includes straps and a whistle for safety. Life jackets are essential safety equipment for boats, swimming, or water sports, especially in emergencies or for individuals who are not strong swimmers. They are designed to turn a person face-up in the water, ensuring their airway remains clear and helping them stay afloat until rescue or help arrives.
