CO2 (Carbon dioxide) suppression systems raise the level of carbon dioxide that is concentrated in the fire, which neutralizes the oxygen supporting the fire and thus extinguishes the flame. One of the best features of a CO2 (Carbon dioxide) suppression system using an FM 200 Fire Suppression setup is that it does not negatively affect sensitive equipment like electronics and high voltage

Although carbon is usually a reducing agent, under acidic conditions elemental carbon is a moderately strong oxidizing agent. The large energy of the carbon–carbon bond makes activation energy requirements for the reaction so high that direct reduction of carbon—e.g., to methane (formula CH 4 )—is impractical.
