What is a "personal flotation device" (PFD)?

A personal flotation device (PFD) is specifically designed to keep a person afloat in water, which is essential for safety while boating. PFDs can come in various forms, such as life jackets, vests, or buoyancy aids, and are critical for preventing drowning if someone falls overboard or is stranded in water. They are an important part of boating safety regulations and are required to be available on board vessels.

The other options do not accurately describe a PFD. While fishing equipment may include items like rods and tackle boxes, they do not serve the function of providing buoyancy. Emergency signaling devices, such as flares or whistles, are used to alert others in case of distress, but they do not aid in flotation. Lastly, a container for storing safety gear is not related to flotation devices at all, as it simply refers to a storage solution rather than a safety item meant to assist a person in water.
