Date May 11, 1994A fire safety coating, particularly intended for application to hydrocarbon-conducting steel pipes (1) in the splash zone underneath oil plants at sea, consists of at least three layers, where the outer layer (5) is a mechanical protecting layer of rubber or plastic material, the next inside layer (4) is a flame-stopping layer comprising inorganic fibers and a rubber material, and an inside layer (3) is a rubber material which reacts particularly at a high temperature to liberate gases which both prevent inward penetration of oxygen and cause a transformation of the rubber material in the flame-stopping layer (4) to form a hard shell.
