Abstract: A personal flotation device for use in emergency situations. The device includes an elongate, flotable stream member that increases the visibility of the individual wearing the device to thereby increase the probability that rescuers will visually sight the individual. The streamer member is stored in a rolled configuration in a compartment of a waist belt and is deployed when buoyancy-providing air bag members are inflated. A plurality of collapsed air bag members are stored in as many compartments of the belt, and they are inflated by gaseous fluids when ring members associated with gas-filled cartridge members are pulled by the individual at the time the water is entered.
