Abstract
A method of extinguishing a fire, which includes pre-positioning a fire extinguishing device which includes at least two reactants such that when the reactants are activated they react to create solid particulate products having a diameter of about one micron or less such that, when the products come in contact with the fire they chemically inhibit the chain reactions of the fire flame and bring about the extinguishing of the fire. In one embodiment, the device is submerged in a liquid coolant and includes means for preventing entry of coolant into the device while allowing the escape of said products into the coolant when activated. Another embodiment is used to generate non-toxic smoke using a device which includes a first reactant which is potassium chlorate, potassium perchlorate, potassium dichromate, cesium nitrate or potassium nitrate, and a second reactant serving as a reduction agent. When the reactants are activated they react to create solid particulate products having a diameter of about one micron or less which creates a smoke.
