What is a personal flotation device (PFD)?

A personal flotation device (PFD) is specifically designed to keep a person afloat in the water, enhancing their safety while swimming, boating, or engaging in other water activities. PFDs are critical safety equipment that helps prevent drowning by providing buoyancy and keeping the wearer's head above water, even if they are unconscious or unable to swim.

This definition distinguishes the PFD from other options, which do not accurately represent its function. For example, swim fins assist with swimming but do not provide flotation support. A type of boat accessory may refer to any additional equipment or parts needed for a boat but lacks the life-saving aspect of a PFD. Similarly, a water purification device is unrelated to flotation and serves a completely different purpose, which is to make water safe for consumption. Understanding the specific role of a PFD emphasizes its importance in water safety practices.
