Abstract (en)
[origin: EP0069393A1] For the early detection of fires smouldering in containers containing lignite dust, the presence of gas containing hydrogen and/or hydrocarbons is measured within the containers, respectively around the containers, those gases not being normally present in lignite dust or being present in very small amounts which are hardly detectable and appearing only with the formation of smouldering fires.
