Abstract：To enhance the quantitative risk assessment method for domino accidents,this study investigated the synergistic impact between the wind and the physical effects (thermal radiation,toxic gas leakage) of different types of accidents.The mechanism of the synergistic effect was analyzed using empirical models.The synergistic situation between fire and toxic gas leakage was simulated using an experiment device model in computational fluid dynamics (CFD) software.The simulation results revealed that the synergistic effect could amplify the accident consequence severity.A hazardous chemical warehouse was taken as a case study for quantitative risk assessment.It was found that the synergistic effect would significantly amplify the individual risk,while the wind could either amplify or inhibit the risk,depending on the specific situation.The result indicates that the synergistic physical effects should be considered in the quantitative risk assessment of domino accidents.This research can serve as an important reference for improving the accuracy of the quantitative risk assessment for domino accidents.
