Correspondence Analysis on Exploring the Association between Fire Causes and Influence Factors

The objective of this study is to explore the associations between the fire causes and the influence factors that include provinces, months, hours, building types and places. The fire causes that are obtained from China fire statistics are composed of arson, electric, production, careless with fire, smoking, playing with fire, self-ignite, unknown and others. The results show that the tendency of fire causes of various provinces is different. Fires occurred in January and February is trend to be strongly associated with playing with fire. The difference of fire causes between night and daytime is obvious. It is clear that the daytime trend to be associated with smoking, careless with fire, production operation and playing with fire, while the night group trends to be associated with arson, unknown, others, electrical fire and self-ignite. It is shown that significant differences of fire causes exist among the building types and the places. Multi-storied buildings have close association with electrical fire. Personnel crowded places are trend to be associated with electrical fire while the vehicles are trend to be associated with self-ignite. Finally, the study highlights that correspondence analysis is an appropriate technique to explore the relationships among fire statistics data and can play a complementary role in analyzing fire data.
