Aerosol systems

The oxides of alkaline metals in the substance of fine solid aerosols, which have extensive surface and being produced during the burning of solid fuels and pyrotechnical compounds. These compounds can burn independently without air access. The substance has a very high extinguishing ability for the hydrocarbon flames excelling the extinguishing gases.
Unlike gaseous agents, the total flooding effect is achieved without increasing the pressure in the protected area/volume
Fire extinguishing is accomplished by the interruption of the chemical chain reactions occurring in the flame and not by the depletion of oxygen and/or cooling as suggested by the traditional triangle of fire.
