Bibliography: | Abstract : Aluminum grinding process using wet dust removal system can avoid dust explosion, but there is a risk of hydrogen explosion accident. The research on the risk assessment of aluminum wet dust removal system and safety management is limited. A WBS- RBS-BN evaluation method for hydrogen explosion accident is presented. The coupling matrix and hydrogen explosion fault tree could be identified by decomposing WBS-RBS the risk factors of wet dust removal system. The fault tree could be changed into Bayesian networks, and the explosion probability is 5. 54E -07. After calculating the posterior probability of basic events, basic events leading to the accident are clarified and identified. The study is helpful for the guidance of safety management. 21-1344/T WANG Yan-tong,XU Kai-H(School of Resources & Civil Engineering,Northeastern University, Shenyang 110819, China. ) WBS-RBS; BN ; wet dust removal system; aluminum alloy dust; hydrogen explosion accident |
