Abstract
Recent buildings have been more unburnable than before because changing of construction methods, progress of building materials, preparation of the related laws and regulations and so forth. But buildings have been more unextinguishable contradictory, and extinguish time need more longer than before. There are problems ; Is not the water application ratio low ? How much is the water damage area even if the water is used for extinguishing ? If we survey these problems, it is useful in order to make fire fighting planning. Then we investigated these items as a part of basic study on the extinguishing of the building fire.
