What is the purpose of a throwable PFD?

The purpose of a throwable PFD (Personal Flotation Device) is specifically designed to assist in rescue situations. This type of PFD is not intended to be worn by an individual at all times like standard life jackets, but rather it is meant to be thrown to someone in the water who may need assistance.

Throwable PFDs, such as cushions or rings, provide a valuable safety tool by allowing a rescuer to reach out and offer buoyancy to a person who may be struggling, improving their chances of staying afloat until they can be rescued. This function is critical in emergencies where immediate personal flotation may be necessary for someone in distress.

Other options, such as wearing the PFD at all times, pertain more to traditional wearable life jackets, while providing flotation for divers is not the primary purpose of a throwable device, and holding additional gear does not accurately describe the function intended for throwable PFDs. The focus is clearly on their role in aiding rescue efforts, making option B the correct choice.
