What is a feature of a Type IV flotation device?

A Type IV flotation device is specifically designed to be thrown to a person in need of assistance. It is typically recognized as a throwable device, such as a buoy or ring buoy, that can provide immediate flotation support to someone in the water. This design allows for quick deployment in emergencies, making it an essential safety feature on many boats.

In contrast, devices designed to be worn typically fall under different classifications, such as Type I, II, or III, which are intended to be donned by individuals for continuous use. A Type IV flotation device is not specifically for children; instead, it is meant for general use for anyone who may find themselves in a water emergency. Lastly, Type IV devices are not permanent fixtures on a boat; rather, they are kept on board and need to be accessible for use in an emergency situation.
