Abstract
From ancient times fire has been extinguished mainly by using water. But there may be some problems in large amount of water discharge against fire, such as enough water volume for fire extinguishing may not be secured in case of large-scale natural disasters, and also secondary damage may be caused by discharged water. CAFS, one of fire extinguishing method by using air foam, is the solution because it utilizes small amount of water very efficiently. This report presents an overview of fire extinguishing with air foam, how to generate it and verification experiments of fire extinguishing effect with CAFS foam in MORITA Corporation.
