Abstract
A high expansion foam fire-extinguishing system including: an emission nozzle () to which a foam solution (Wg) prepared by mixing water (W) with a foam concentrate () containing a surface active agent () is sent under pressure; a flow passage (); and a foam screen () upon which the foam solution discharged from the emission nozzle impinges. The foam concentrate used is one of one in which a mixing ratio of the foam concentrate with respect to the foam solution is an adjusted mixing ratio higher than a standard mixing ratio and one in which a content rate of the surface active agent with respect to the foam concentrate is a design content rate that is higher than a standard content rate, and in which a mixing ratio of the surface active agent is a concentration for design foam expansion ratio.
