Abstract
Fire extinguishment experiments were conducted for liquid pool fire using water mist contained with 0 to 5% volumetric concentration of ethanol. The time of fire eextinguishment shows the minimum value at 3% contained of ethanol in water mist, and also the dynamic behavior to extinguish is more safety without fire expansion than that for pure water mist. The improvement of water mist extinguishment is mainly resulted in decreasing the mist diameter by adding small amount of ethanol.
