jaue2015072: Development of the Planning Method of Self-defence against Fires Using Portable Fire Pumps : Case Study on a Historic Urban District

Abstract

Currently, the number of preservation districts for groups of traditional buildings (PDGTBs) is accounted for 110 districts (as of July, 2015), and there is growing tendency to preserve historic urban districts across the nation. However, its population is aging not only in PDGTBs but also in this entire nation. As a result it is difficult for community disaster preparedness and volunteer fire corps to obtain personnel and keep them active, therefore, we must make a new firefighting measurement. Especially, the buildings in city-type PDGTBs are usually fragile in terms of disaster prevention; thus, it is necessary to take measures for initial fire to preserve historic buildings. However, the measures are not considered in necessary time of firefighting. Therefore, we must evaluate the disaster prevention method quantitatively. There are PDGTBs in which local voluntary disaster management is active. We investigate the method of self-defence against fires in such cities aiming to apply it place where population aging is accelerates. We estimated the time required before spraying water is ready using a portable fire pump though our experiment with targeted local residents and university students. Based on the findings of the experiments, we proposed layout plan of portable fire pumps in one of the PDGTBs “Kauemoncho”, Tochigi. And then, we demonstrated effect and problem of our firefighting measurement.
