For a fire to ignite three elements are needed: Heat, combustibles and an oxidizing agent, usually oxygen. When these elements are present and in the right mixture a natural fire will occur. A fire can be prevented or extinguished by removing any one of these elements. Once a fire has started, the exothermic chain reaction sustains the fire and allows it to continue until or unless at least one of the elements of the fire is blocked.
Traditional fire fighting methods either deny the burning fire the oxygen it needs or they lower the temperature of the fuel below the ignition point or by creating a barrier of inert gases thus attacking the chemical reaction responsible for the fire.
With the N2 OXYGEN REDUCTION SYSTEM® we actively prevent the combustion process to get started by uninterruptedly reducing the amount of oxygen.
