Phénomènes naturels, prévenir les accidents majeurs

Abstract : Interaction between natural (earthquake, flooding, lightning, storm, forest fire…) and technological hazards within industrial plants could have disastrous consequences on installations containing hazardous substances, electrical systems… In this context, INERIS has worked to improve Natech accidents knowledge and prevention in the framework of APSYRIS and INteg-Risk projects, with the Joint Research Center (JRC) and the University of Bologna as partners. The main results are as following: a detailed analysis of past Natech accidents, a model of dynamic equipment response to earthquake, a consolidated methodology combining a quantitative risk assessment approach (QRA) and the bow tie method for piping, atmospheric and pressurised vessels, recommendations for the establishment of an early warning system for industrial plants in flooding areas. Considering the recently growing importance of Natech aspects, INERIS must continue to provide its expertise. Behaviour to earthquake of specific equipments (valves, sensors, cables…), development of models to predict behaviour of equipments in case of flooding, analysis of power supply networks vulnerability, making emergency plans more robust in relation to Natech risk, taking into account several natural hazards occurring simultaneously (earthquake and flooding, drought and forest fires…)… could be the research direction followed by INERIS in the coming years.
