Fixed gaseous fire suppression systems
• Carbon dioxideOver eighty yearsExtinguishes the fire primarily by reducer the oxygen
concentration and provides localized coolingLocal application and total flooding application
Fixed water system
• Water mist90% droplets less than 1 mm in diameter To cool the fire source by removing the heat and
suppressing the fireDisplaces oxygen in the atmosphere
