We have developed a new type of hose nozzle, which uses either water or compressed air foam (CAF), as a more efficient fire-fighting strategy. In this paper, a description of the measured spray range and foam expansion of both the prototype nozzle and conventional nozzles is given. The results show that the spray range of the prototype nozzle is equal or superior to that of conventional nozzles. The foam expansion capability of the prototype nozzle is far superior to that of existing nozzles. From these results, it was confirmed that the new type of hose nozzle suggested in this paper will be an effective addition to existing firefighting equipment, resulting in a more efficient firefighting strategy.
