A 30 inch lifebuoy with reflective tape which is SOLAS compliant (International Convention for the Safety of Life at Sea). Designed to be thrown to a casualty in the water, a lifebuoy provides buoyancy to prevent drowning and is usually attached to a throwline to enable retrieval. Regulations stipulate that lifebuoys should be of a certain diameter, be constructed of an inherently buoyant, non-fading material (but not loose granulated material such as cork shavings or a material that depends on the inflation of air), that does not sustain burning/melting after 2 seconds of full envelopment in fire, is able to withstand a 30m drop into the water and support a 14.5kg load of iron in fresh water for 24 hours. This example is extrusion blow moulded of high density polyethylene (HDPE) and filled with polyurethane foam (to prevent water ingress) through a 15mm hole which is then sealed and covered by reflective tape. The lifebuoy is highly visible, durable to withstand outdoor exposure, has a 180N buoyancy rating and features a grab line to assist the casualty in being pulled to safety. 30 inch lifebuoys are typically seen installed at beaches and locations where there is a straight drop to the water such as at docks, piers, harbours and on boats.
