Abstract: Methods and related systems for extinguishing a fire in a volume which includes pre-positioning a fire extinguishing medium in or near the volume. The medium includes at least two reactants, typically an oxidant and a reducing agent which are activated manually or automatically in response to the fire causing the two reactants to react with each other and to form an aerosol capable of interacting with the propagation centers of the fire, interrupting the propagation of the fire, and thereby extinguishing it.

The medium includes at least two reactants, typically an oxidant and a reducing agent which are activated manually or automatically in response to the fire causing the two reactants to react with each other and to form an aerosol capable of interacting with the propagation centers of the fire, interrupting the propagation of the fire, and thereby extinguishing it. The methods and systems further include various mechanisms for cooling the gases formed upon the reaction of the two reactants so as to enable the gases to disperse more evenly and more effectively over the fire.
