LIFE PRESERVERS AND BUOYS

Life-preservers are chiefly of the belt or jacket type, made to fit about the body and rendered buoyant by slabs of cork

sewed into the garment, or by rubber-lined air-bags. The use of cork is usually considered preferable, as the inflated articles are liable to injury, and jackets are preferable to belts as they can be put on more quickly.

Life-buoys are of several types, but those most common are of the ring type, varying in size from the small one designed to be thrown by hand to the large hollow metal buoy capable of supporting several people. The latter are usually carried by sea-going vessels and are fitted with lamps which are automatically lighted when the buoy is dropped into the water.
