What is the primary role of a personal flotation device (PFD)?

The primary role of a personal flotation device (PFD) is to keep a person afloat in water. PFDs are specifically designed to provide buoyancy, which helps individuals who are at risk of drowning to stay above water until they can be rescued or reach safety. They achieve this by using materials that are buoyant, such as foam, or by incorporating air pockets, allowing the device to support the weight of a person effectively.

While there are other benefits associated with PFDs, such as offering some warmth in cooler water or potentially aiding in swimming efforts, their main function is to ensure that an individual remains buoyant and safe in water. Proper usage of PFDs can significantly reduce the risk of drowning and enhance survival chances in emergency situations.
