A Comprehensive Investigation on the Fire Hazards and Environmental Risks in a Commercial Complex Based on Fault Tree Analysis and the Analytic Hierarchy Process

Abstract

This paper focuses on the fire risk assessment for commercial complex, as the variety of fire accidental triggers inside could be a big threat to the public fire safety, leading to catastrophic loss in human lives and properties. Both the qualitative and quantitative analysis were imposed on a typical large commercial complex to recognize the potential fire-causative factors in this paper. Applying the fault tree analysis, the basic events leading to fire are acquired, and they are then further reclassified based on the analytic hierarchy process. Taking the damage of the accident as the target layer and the fire-causative factors, the equipment operation factors and firefighting factors as the criterion layer, the assessment index is well established. The risk of each factor is quantitatively evaluated, and the effect of each factor on the target layer is analyzed. The result of the fault tree analysis and analytic hierarchy process shows good consistency, in which human behavior is the main factor leading to the fire occurrence, followed by the combustible material, the rescue speed and the staff assignment factors. The results are beneficial for general decisions and measures in public fire safety management.

Fire Safety Index for High-Rise Buildings in the Emirate of Sharjah, UAE

“…From the literature review, 19 factors affecting fires in residential building were identified, and we classified them into three categories: management factors, human factors, and technical factors, such as fire regulations, fire enforcement regulations, fire research and development, facilities management and policies, fire data analysis/availability, accident investigations, public/contractor attitudes, rescue speed, staff assignments, human behavior, fire training, fire knowledge, fire culture of society, fire technology, lack of/improper maintenance, fire equipment, building design, combustible materials, and climate change. The factors were identified after we reviewed papers [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35], and not all the factors were applicable to the Emirate of Sharjah. It appeared that after conducting three round of Delphi techniques, the main elements affecting high-rise residential buildings were the identifies and representations provided to the subject matter experts through the analytic hierarchy process (AHP), and the outcomes are shown in Table 1.…”

Analysis of the fire risks and mitigation approaches in the apparel manufacturing industry: Implications toward operational safety and sustainability

“…Most existing studies described fire risk factors with four clustered divisions-causative, detection, protection, and egress [ 27 , 39 , 94 ]. Therefore, this study has also considered these four criteria by analyzing the existing literature on fire risk.…”

Crafting a framework: a Delphi method approach to formulating a maker literacy assessment model for primary school students in China

“…If an item does not fit one of the acceptance criteria, the professional group evaluates and debates on it to determine whether it should be eliminated or retained. Next, the analytic hierarchy process (AHP) was utilized to calculate the precise weights of the components inside the Maker literacy model (Wang et al, 2020). YAAHP 10 software was used to calculate the weights.…”
