An Experimental Study on the Improvement of Fire Extinguishing Performance of Water Mist with Foam

We carried out the water mist fire extinguishing experiments with the 3 kinds of foaming agents varied on the nozzle height. Test result showed that 2% AFFF (Aqueous Film Forming Foam) and 1% synthetic foaming agent for water mist system are the faster extinguishing time than the pure water mist and 3% AFFF solution. Additionally, the best fire extinguishing performance of pure water mist was shown at 3.5m nozzle height and that of the foaming agents shown at 4m nozzle height.
