Abstract：Risk analysis on direct property damage for 1 356 major fire incidents in towns from 2000 to 2005 is carried out based on association rules analysis with respect to time, place and cause by SPSS Clementine 8.1 software. The results show that a fire may easily turn into a major fire incident with direct property damage, in cases of electric fire in workshop, storeroom fire in November, shop fire from 2:00 to 3:00, electric fire from 23:00 to 24:00, electric fire and fire from 18:00 to 19:00 in July, workshop fire due to electric failure in July and shop fire due to electric failure from 21:00 to 22:00. These results may serve as a guidance for taking more effective fire protection measures and improving the efficiency of combat readiness for fire fighting.
