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.

Key words: WBS-RBS, BN, wet dust removal system, aluminum alloy dust, hydrogen explosion accident
