A compressed air foam system (CAFS) is used in firefighting to deliver fire retardant foam for the purpose of extinguishing a fire or protecting unburned areas. Typical components include a water source, a centrifugal pump, foam concentrate tanks, a direct-injection foam proportioning system on the discharge side of the pump, a mixing chamber or device, a rotary air compressor, and control systems to ensure the correct mixes of concentrate, water, and air. ==Description== A compressed air foam system is defined as a standard water pumping system that has an entry point where compressed air can be added to a foam solution to generate foam. The air compressor also provides energy, which, gallon for gallon, propels compressed air foam farther than aspirated or standard water nozzles. It is proven that CAFS attacks all three sides of the fire triangle simultaneously. The foam blankets the fuel, thereby reducing the fuel’s capacity to seek out a source of oxygen. The CAFS solution adheres to ceilings and walls, more readily aiding in rapid reduction in heat. Also, the opaque surfaces of the foam, as it adheres to walls and ceilings, shield the fuel source from radiant energy. (Brooks, 2005; Brooks, 2006) CAFS may also refer to any pressurized water style extinguisher that is charged with foam and pressurized with compressed air. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Compressed air foam system」の詳細全文を読む スポンサード リンク
