Tighten collars, cuffs, shoes and hoods. Cover your head, if possible. Swim only to reach a nearby boat, person or floating object. Remain as still as possible. Devote your efforts to getting out of the water, boarding a boat, raft or other floating device, or climbing on top of a capsized boat.
Care involves getting the victim out of the water and out of the wet clothes.
Warm the victim gradually by wrapping him or her in blankets or putting on dry clothing and moving into a warm environment. If the victim is alert, administer warm liquids to drink that do not contain alcohol or caffeine. DO NOT warm the victim too quickly by immersing in warm water as this may cause dangerous heart rhythms. Seek medical assistance.
