This disclosure relates to a fireguard for protecting a hose or an assembly of a hose and fittings. The fireguard includes a layer or tube of a silicone compound which is positioned around the hose, and a metal shroud or sleeve which encloses the layer of silicone compound. The silicone compound and the shroud protect the hose at normal temperatures and for a short length of time at a high temperature. In the event the high temperature persists for a length of time, the silicone compound decomposes to a layer of silica ash, which is held in place between the shroud and the hose, and the ash forms an excellent heat insulation for an extended time. The shroud is preferably flexible so that the hose may be bent, and the fireguard preferably also includes another layer of the silicone compound and a collar around each hose fitting.
