Carbon dioxide (CO2) gas has been used as an extinguishing agent in fixed installations since the beginning of the twentieth century. NFPA-12 ( National Fire Protection Association ) Rules and BIS 6382 codes for design of such system are used as standards for CO2 extinguishing systems. These fire extinguishing installations are usually provided on premises where water and foam cannot be used. CO2 can be stored in high pressure seamless steel cylinders in liquid form with maximum filling ratio of 0.667 kg/liter of cylinder volume.
