All About PFDS
DESCRIPTIVE TYPES OF PERSONAL FLOTATION DEVICES (PFDs)
A TYPE I PFD, or OFFSHORE LIFE JACKET provides the most buoyancy. It is effective for all waters, especially open, rough, or remote waters where rescue may be delayed. It is designed to turn most unconscious wearers in the water to a face-up position. The TYPE I comes in two sizes: Adult size provides at least 22 pounds of buoyancy, the child size, 11 pounds, minimum.
A TYPE II PFD, NEAR-SHORE BUOYANT VEST is intended for calm, inland water or where there is a good chance of quick rescue. This type will turn some unconscious wearers to a face-up position. The turning action is not as pronounced nor as effective as a TYPE I. An adult size provides at least 15.5 pounds buoyancy, a medium child size provides 11 pounds. Infant and small child sizes each provide at least 7 pounds buoyancy.
A TYPE III PFD, or FLOTATION AID is good for calm, inland water, or where there is a good chance of quick rescue. It is designed so that wearers can put themselves in a face-up position in the water. The wearer may have to tilt their head back to avoid turning face down. TYPE III has the same minimum buoyancy as a TYPE II PFD. Float coats, fishing vests, and vests designed for various water sports are examples.
A TYPE IV PFD, or THROWABLE DEVICE is intended for calm, inland water with heavy boat traffic, where help is always present. It is designed to be thrown to a person in the water and grasped and held by the user until rescued. It is not designed to be worn. Type IV devices include buoyant cushions, ring buoys, and horseshoe buoys.
A TYPE V PFD, or SPECIAL USE DEVICE is intended for specific activities and may be carried instead of another PFD only if used according to the approval condition on the label. Some Type V devices provide hypothermia protection. Varieties include deck suits, work vests, board sailing vests, and Hybrid PFDs. A TYPE V HYBRID INFLATABLE PFD is the least bulky. It contains a small amount of inherent buoyancy and an inflatable chamber and must be worn when underway to be acceptable.
