Emergency Flotation Systems (EFS) are emergency systems installed on larger commercial and military helicopters in order to prevent the airframe sinking in the event of a crash landing on water. The floats may be packed within spaces inside the airframe or as externally mounted packs on the helicopter skids .
The MES consists of five components. Controls – used to initiate the device in an emergency situation. [9]Stowage box – contains essentials for the evacuation, including the chute and the fixed appliances, such as seats, rails, etc. [10] Composed of marine grade aluminum along with inflation cylinders, usually kept on the deck taking as little as 4 m 2 of storage space.

Using the arms or legs to exert a downward pressure, the subject raises himself sufficiently so that the mouth is above the surface and a breath is taken, before dropping back into the relaxed float.
An isobaric float aims to follow a constant pressure plane, by adjusting the ballast's weight to attain buoyancy to a certain depth. It is the most easily achieved model. [1] To achieve an isobaric float, its compressibility must be much lower than that of seawater.

A lifebuoy or life ring, among many other names (see § Other names), is a life-saving buoy designed to be thrown to a person in water to provide buoyancy and prevent drowning. [1] Some modern lifebuoys are fitted with one or more seawater-activated lights to aid ...

A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suit that is worn by a user to prevent the wearer from drowning in a body of water.
The system was developed from the earlier to the Rhino ferry. The Mexeflote is named after the Military Engineering Experimental Establishment (MEXE) in the UK where it was designed, [ 1 ] in conjunction with the neologism "flote" instead of float .
