Lifebuoy"A lifebuoy, ring buoy, lifering, lifesaver, life donut, life preserver or lifebelt, also known as a "kisby ring" or "perry buoy", is a life saving buoy designed to be thrown to a person in the water, to provide buoyancy and prevent drowning. Some modern lifebuoys are fitted with one or more seawater-activated lights, to aid rescue at night. The lifebuoy is usually ring- or horseshoe-shaped and has a connecting line allowing the casualty to be pulled to the rescuer in a boat. They are carried by ships and are also located beside bodies of water that have the depth or potential to drown someone. They are often subjected to vandalism which, since the unavailability of lifebuoys could lead to death, may be punished by fines (up to £5,000 in the United Kingdom) or imprisonment." - (en.wikipedia.org 20.11.2019) Security Rescue
