1. An inerting method for reducing the risk of and for extinguishing fires in enclosed spaces, said method comprising the steps of monitoring the oxygen content in a wall-enclosed space to produce measured oxygen values;

  • when said measured oxygen values exceed a selected base inerting level capable of reducing the risk of combustion yet supporting life, reducing the oxygen content in said space to said selected base inerting level;

    in the event of a fire in said space, detecting selected fire characteristics in said space and producing a complete inerting signal, and in response to said complete inerting signal, rapidly further reducing the oxygen content in said space to a selected complete inerting level incapable of supporting combustion.
