AN INFLATABLE HOSE SYSTEM
An inflatable hose system which may act as a boom for rescue purposes or for controlling the flow of surface borne contaminants of rivers, lakes and seas and comprising first and second hose lengths (10, 11) each having one end (12) flattened and sealed to be chiselshaped and the other end provided with a coupling (15, 16). The two lengths (10, 11) and any interposing standard hose lengths may thus be coupled together and inflated to a pressure in the range of 2 to 3.5 bar to provide a boom of the required length, and one of the hose lengths includes an inflation valve (20). The hose length may be connected together in mutual alignment thus to produce a straight boom or with the interposition of elbows to form a curved boom capable of containing floating objects or substances.
