A container or other liquid holding means, e.g. a pipeline, for inflammable liquids is provided with a fire-extinguishing structure. This comprises a blanket of a porous, flame-permeable, heat-resistant material, e.g. expanded metal foil, which is supported for contact with the surface of the liquid e.g. on floats embedded in the blanket, so that the blanket extends in contact with substantially the whole of the liquid surface. In the case of a pipeline, the blanket may be supported adjacent the pipeline in a normally-empty catchment facility which is intended for retaining spillages or leakages of liquid from the pipeline. The blanket has large non-capillary interstices. On ignition of the vapor/air mixture above the blanket, the flame front recedes downwardly into the blanket and the flames become extinguished. This arrangement can reduce the fire hazard associated with large-capacity containers for inflammable liquids.

A container for inflammable liquids having an upwardly extending sidewall, a body of inflammable liquid held within the container, and a fire-extinguishing structure comprising a porous blanket extending over substantially the whole of the surface of the liquid in the container, said blanket being of heat-resistant expanded metal foil material comprising interconnected flat mesh strands defining diamond-shaped openings having interstices of non-capillary size that are sufficiently large that they permit a flame front to propagate through the blanket and means supporting said blanket in contact with said liquid and in close abutment with the container sidewall and with a thickness of the blanket material extending above the liquid surface sufficient to suppress combustion of the liquid at its surface.
