Abstract
A fire is extinguished and suppressed, by a dual stage fire extinguisher. In a first stage, a sufficient amount 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 prevent its re-ignition. Since suppression typically requires less of the inerting agent than extinguishing, a reduction in the weight of the inerting agent is achieved with the dual stage process making the system particularly amenable to aircraft applications such as in an engine nacelle or cargo dry bay.
