Study on the situation and characteristics of high casualty fires in China based on statistics analysis

In this paper, the characteristics of high casualty fires in China from 2002 to 2010 are analyzed by using statistical analysis. The overall situation and spatio-temporal distribution of the high casualty fires are analyzed, and the fire causes and locations are investigated. The results indicate that the high casualty fires are in a decreasing trend with fluctuations, and they highly depend on economic factors. The fires happened more often in the beginning and end of the year than in the middle of the year, more often at nights than in the daytime. Dwelling houses account for the highest fire frequencies and deaths. Electrical fires and abuse of fires account for most of the high casualty fires.
