Young Black Haired Girl On The Lake With The Ring Buoy

Lifebuoys are not considered suitable by the Royal Life Saving Society for use in swimming pools during emergencies, because they are heavy and hard, whereby throwing them into a crowded pool has the potential to cause more harm than good by injuring either the casualty or nearby pool users. In these locations lifebuoys have been superseded by more modern devices such as the torpedo buoy.
In the United States, Coast Guard approved lifebuoys are considered Type IV personal flotation devices. One Type IV PFD is required on all boats 16 feet or larger (except canoes and kayaks).
