Abstract
A method for extinguishing a fire in a volume having walls or other surfaces includes pre-positioning a fire-extinguishing device in communication with the volume. The device includes a solid-fuel composition comprising a first reactant and a second reactant. The pre-positioning of the method comprises painting or coating the composition on surfaces of the walls or on the other surfaces of the volume. A coolant material may also be painted over the pre-positioned composition. The composition is activated by igniting it so as to cause the first and second reactants to react with each other to create an aerosol of solid particulate products having a diameter of about one micron or less. The solid particulate products of the aerosol are effective in extinguishing the fire by chemically inhibiting the chain reactions of the fire.
