Abstract

Natural-technological accidents, or NATECHs, reveal a particular exposure and vulnerability of industrial facilities to natural hazards and disasters. NATECH is seen as an emerging risk due to 3 main Emerging Risk issues. ERi 1 : Industry development in areas exposed to natural hazards or disasters : higher hazard potential, higher frequency of accidents ; ERi 2 : Growing complexity of the industrial system : higher dependency on vulnerable networks (telecom, transport, utilities, lifelines) ; ERi 3 : Climate change is believed to induce more severe/intense natural disasters, with subsequently growing impacts on industrial facilities. Within the iNTeg-Risk project, several tasks were dediated to investigate the NaTech issue (T1.5.3 - ERRA NATECH, and T2.5.4). ERi 1 and 3 were mainly considered within the work carried out. However, the (un)availability of safety barriers should be considered when establishing event trees and failure trees (accident risk; so-called bow-tie approach, etc.). In the paper, the developments made in the ERRA NATECH are presented : A new risk analysis methodology for NATECH events and a set of new KPIs are discussed and showed. The handbook of good Practices for NATECH mitigation will be a main output of the ERRA participants. A preliminary application of the results to a case-study was also carried out.
