Extinguishment By Cooling

• Water when spray on the fire can absorbs most heat when converted to steam . 
• Water converts to steam easier in droplets form . 
• Wetting combustible materials is a method often employed to prevent the ignition of unburned material . 
• Amount of water required depends on the temperature of fire . 
• How fast the fire is extinguished depends on how soon water is applied on the fire . 
• Water is usually not effective for gaseous and flammable liquids that have flash point below the temperature of applied water .
