Life jackets (PFDs) are marine safety devices designed to provide flotation and keep wearers afloat in lakes, coastal, and rough waters. Approved by the US Coast Guard and Transport Canada, they are used on boats, kayaks, personal watercraft, and during water sports. Types II, III, IV, and V serve different needs, from comfortable wear to emergency rescue and unconscious face-up flotation, for adults, youth, and infants.

What are life jackets and how do they function as personal flotation devices for marine safety?
A life jacket, also called a life vest or PFD, is a coast guard approved personal flotation device that provides floatation in emergency situations while swimming, during water sports, or onboard a boat. Different types of life jacket use foam or inflation to deliver required lbs of buoyancy, help turn unconscious wearers face-up, support infant life and youth life, and improve mobility for rescue. These flotation devices are designed to be worn or thrown, aiding survival, grab, and rescue in marine environments.
How do foam and inflatable life vests differ in flotation, inflation method, and mobility?
Foam life vests, commonly used as Type III or Type IV personal floatation devices, provide constant float without activation, meet USCG-approved and Transport Canada approved requirements, but can feel bulky and uncomfortable when worn for long periods or seated. Inflatable life vests, usually classified as Type V, rely on manual or automatic inflation to create floatation, offering greater mobility and comfort, while still meeting coast guard-approved standards for approved life and rescue use where flotation devices may be required.
How should PFDs be stored and handled to maintain approved life performance over time?
PFDs should be stored in a dry, well-ventilated place away from direct sunlight and heat to preserve materials and buoyancy performance over time. They should not be used as seats, crushed, or left under heavy objects, as this can reduce comfort and flotation effectiveness. Regular inspection for wear, damaged rings, or fabric issues helps ensure the device remains comfortable to wear and ready if rescue may be needed.
