Fixed gaseous fire suppression systems Carbon dioxide  Over eighty years  Extinguishes the fire primarily by reducer the oxygen concentration and provides localized cooling  Local application and total flooding application

Fixed water system Water mist  90% droplets less than 1 mm in diameter  To cool the fire source by removing the heat and suppressing the fire  Displaces oxygen in the atmosphere
