Typologi over uønskede hendelser

This report presents a typology for unwanted incidents that may pose a threat to national safety and security in Norway, in particular during the coming 10 years. The rationale for making this typology is to describe the broad spectrum of threats that the emergency preparedness work in Norway has to address. It will also be a useful tool for developing specific scenarios. Compared with earlier works on similar typologies, our approach is innovative in two ways. It includes a new class of incidents, aggregated individual actions, and the typology is accommodated for combining several incident types in one scenario. The main dimensions in the typology are cause and primary effect, but it also comprises minor divisions in subsections of the typology. An evaluation of the typology concludes with that it is exhaustive, practically applicable, comprehensible and innovative, but not excluding or sufficiently pragmatic. In total, the typology contains 77 incident types, divided between intended and non-intended incidents. The incident types are rather general, so the potential for local variations is huge. Also, by combining different incident types, it is possible to define numerous specific scenarios. The typology succeeds in presenting the principal unwanted incidents that might pose a threat to Norwegian safety and security.
