Investigation of fire accidents is a primary and imperative procedure for human disaster prevention. It engages with the development on the planning program for disaster preventive-remedy and salvage in a city (or a county), and helps to mitigate this calamity effectively in the future, even for a nation. In this study, we investigated and analyzed fire accidents for one of typical rural areas in Asia–Yunlin county, Taiwan, from January, 2003 to August, 2005. This study deals with the statistical data from the Fire-Fighting Department, Yunlin county, Taiwan, including the frequency/probability, potential hazard grades of fire cases within its 20 administrative divisions, and fire occurrence causes, locations, times, divisions, etc., along with comprehensive surveys on the property damage and casualties in Yunlin county during these years. The analytical outcomes indicated that the higher the population concentration (Douliou city, Huwei town, Siluo town and Beigang town), the greater the probability for fire disasters for Yunlin county. This study could help develop corresponding strategies of fire prevention for an agricultural county and even promulgate related regulations to avoid future fire mishaps.
