What is the primary function of a life jacket?

The primary function of a life jacket is to float a person in the water. This device is designed to provide buoyancy, which helps keep the wearer’s head above water and reduces the risk of drowning in emergency situations. By doing so, a life jacket increases the chances of survival until rescue occurs. It is vital for safety on the water, especially in instances of unexpected capsizing or accidents.

While warmth, visibility, and protection from sunburn are important aspects to consider when engaging in water activities, they are secondary to the main purpose of a life jacket. The essential role of ensuring that individuals remain afloat makes life jackets a critical safety measure for all boaters and swimmers.
