This paper proposed a new approach, combining root cause analysis (RCA), analytic hierarchy process (AHP), and event tree analysis (ETA) in a loop to systematically evaluate various laboratory safety prevention strategies. First, 139 fire accidents were reviewed to identify the root causes and draw out prevention strategies. Most fires were caused due to runaway reactions, operation error and equipment failure, and flammable material release. These mostly occurred in working places of no prompt fire protection. We also used AHP to evaluate the priority of these strategies and found that chemical fire prevention strategy is the most important control element, and strengthening maintenance and safety inspection intensity is the most important action. Also together with our surveys results, we proposed that equipment design is also critical for fire prevention. Therefore a technical improvement was propounded: installing fire detector, automatic sprinkler, and manual extinguisher in the lab hood as proactive fire protections. ETA was then used as a tool to evaluate laboratory fire risks. The results indicated that the total risk of a fire occurring decreases from 0.0351 to 0.0042 without/with equipment taking actions. Establishing such system can make Environment, Health and Safety (EH&S) office not only analyze and prioritize fire prevention policies more practically, but also demonstrate how effective protective equipment improvement can achieve and the probabilities of the initiating event developing into a serious accident or controlled by the existing safety system.

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.

Software application normally comes along with its event logging feature today. However, with only the software application event log would be hard to determine the root cause if the error occurs beyond the software application boundary. In such circumstance, the time duration of conducting the root cause analysis activity will be easily prolonged. In order to identify the root cause more effectively, multiple event log files from different boundaries that are involved with software application such as Operating System, Networking, Middleware, Database Management System and etc are required. Therefore it will add additional complexity to the root cause analysis process. With such challenge, a new analysis approach is proposed. This new analysis approach is a logic model incorporated with Analytic Hierarchy Process (AHP). It will be sitting at the logic tier to conduct the analysis without interferes the existing software application. The objectives of the logic model is not only to mitigate the time duration prolonging on root cause analysis activity. It is also to increase the accuracy of identifying the actual root cause during analysis activity. Furthermore, this proposed logic model contributes the new knowledge of analysis approach which helps to close the existing knowledge gap in AHP, that can be applied for software application root cause analysis.

Hierarchy Process

The safety status of pipe bridge is often studied by fuzzy assessment. In fuzzy assessment, the structure importance must be calculated first. In this article, structure importance is calculated by Fault tree analysis(FTA) and Analytic hierarchy process(AHP). The result shows that the structure importance calculated by both methods is less than 30% different from each other. That means two methods are of high consistency and both is suitable for pipe bridge.
