The primary purpose of a Personal Flotation Device (PFD) is to keep a person afloat in the water. PFDs are designed specifically to provide buoyancy, ensuring that an individual remains at the surface, which is critical for survival if they find themselves in a situation where they are submerged or in danger of drowning.

While comfort is an important consideration for users, particularly for longer outings, it is secondary to the life-saving function of the device. The PFD’s essential role is safety, and being afloat allows individuals to conserve energy and stay above water until help arrives or they can swim to safety.

PFDs can provide some warmth, particularly in cooler water conditions, but this is not their main function. They may offer some thermal protection, but their chief design and use are centered around flotation. Similarly, while signaling for help in emergencies is critical in boating safety, PFDs themselves do not inherently serve this purpose; other safety gear like whistles or flares are better suited for signaling. Therefore, the primary, life-saving function of a PFD is to ensure buoyancy and keep individuals afloat in water.
