火災危險度部分發現，影響巨城購物中心火災危險度最大之因素為各區販賣商品之燃燒及發煙特性、防火區劃大小，而最大GR及IR分別為GR 67.04及IR 30。
At present, theories of fire risk assessment combining fire property loss have little relevant references, so this study hopes to propose a suitable fire risk management concept combining fire property loss assessment. This study chose a shopping mall as a case analysis. Not only is this based on vast area and internal use complex, but also business professionals invested substantial capital in them; therefore, comparatively speaking, shopping mall have much more value than others in applied studies with property loss. For example, fire features based on Far Eastern Big City shopping mall could be included: heavy smoke, high temperature burning, difficult to escape, rescue difficult, and readily failure of automatic fire alarm equipment and automatic fire extinguishing equipment due to human factors. This study collected fire cases references over years, basic information in shopping mall, and on-site visits based on value of goods. Furthermore, Gustav purt fire risk assessment method was conducted by fire compartment units to obtain GI value (fire damage to the building) and RI value (fire injury inside the building personal). Under the bases on fire dynamics and fire occurrence probability theories, this study obtained fire risk of fire compartment and fire direct property loss value by utilizing analyses methods. After the comprehensive evaluation, we could conclude which fire compartments need to be strengthened in fire prevention, fire protection, and insurance measures. Result discovered that the most significant fire risk factors in Big City shopping mall are combustion features, smoke characteristics, and fire compartment size in each selling district and the largest GR and IR are GR 67.04 and IR 30, separately. According to influence factors of fire direct property loss, the study found that the greatest property loss was by approximately 41.51 thousand NT dollars per year. However, while on-site visits of goods value were conducted, because business professionals were unwilling to disclose or withheld the real price to affect the authenticity of the price. Finally, the study found that under without changing the original commercial scale in Big City shopping mall if the original fire compartment area was reduced to 1/2 scale, GR, IR, and fire direct property loss could be decreased by approximately 23.46~25.06%, 50%, and 61.14~62.31%, separately.
