Which types of Personal Flotation Devices (PFDs) are suitable for swiftwater rescue?

Type III and Type V Personal Flotation Devices (PFDs) are suitable for swiftwater rescue because they are designed to provide both comfort and mobility while ensuring the wearer is buoyant in various water conditions. Type III PFDs are commonly used for activities such as canoeing, kayaking, and other water sports where freedom of movement is essential, making them ideal for swiftwater rescue scenarios where agility and the ability to perform rescues or reach victims is crucial.

Type V PFDs are specialized devices that are applicable for specific activities, including swiftwater rescue. They often include additional features such as built-in harnesses or other safety elements that enhance the performance and security of the rescuer during operations in swift or turbulent water.

The other options, while including PFDs that may provide some level of buoyancy, are not as well-suited for the unique demands of swiftwater rescue, which require optimal performance under conditions of strong currents and the need for rapid maneuverability.
