Abstract: Industrial accidents triggered by natural events (Na-Tech accidents) are a significant category of industrial accidents. Several specific elements that characterize Na-Tech events still need to be investigated. In particular, the damage mode of equipment and the specific final scenarios that may take place in Na-Tech accidents are key elements for the assessment of hazard and risk due to these events. In the present study, data on 272 Na-Tech events triggered by floods were retrieved from some of the more important industrial accident databases. Data on final scenarios highlighted the presence of specific events, as those due to substances reacting with water, and the importance of scenarios involving consequences for the environment. This is mainly due to the contamination of flood water with the hazardous substances released. The analysis of process equipment damage modes allowed the identification of the expected release extent due to different water impact types during floods. The results obtained were used to generate substance-specific event trees for the quantitative assessment of the consequences of accidents triggered by floods.
