The number of fires in forest fields is the highest among fire types, and the process from fire occurrence to extinguishment is affected by many factors, such as time of occurrences, cause of fires, moving vehicles, temperature, moisture, and wind direction. This research adopts the database analysis method, taking the cases of forest field fires in Daya Branch of First Disaster Relief Brigade, TCCFD in 2017 and 2018, as the research target and compiling them. With a powerful database to analyze the causes and formulate improvement suggestions to summarize the correlation of related factors, we hope to reduce the number of forest field fires, avoid wasting firefighting manpower, and serve as a future forest field fire prevention and rescue reference.
