A fire is inerted, extinguished and suppressed, by a dual stage fire extinguisher. In a first stage, a sufficient volume percentage of an inerting agent is delivered to extinguish the fire. Once the fire is extinguished, in the second stage, a different amount of inerting agent is delivered to the fire to suppress it and prevent re-ignition. Since suppression typically requires less of the inerting agent than extinguishing, a reduction in the weight of the inerting media is achieved with the dual stage process making the system particularly amenable to a...
[ We claim:] [1.] A method for inerting a fire in a confined area, comprising the steps of:a) delivering a first inerting agent to said area at a first mass flow rate for a time effective to extinguish said fire; andb) delivering a second inerting agent to said area at a second mass flow rate, less than one fifth of the first mass flow rate, for a time effective to maintain an inerting agent concentration within the area to prevent re-ignition of said fire.
