External Hazard Factors: a new challenge for Safety Science

External Hazard Factors: a new challenge for Safety Science

This is a past event

by Professor Valerio Cozzani, University of Bologna, Italy

In recent years, an increasing concern raised among the protection of population, environment and assets from external hazard factors. For 30+ years, safety research and safety assessment of conventional industrial facilities, as those of the Oil&Gas and chemical industry, primarily addressed the issue of major accidents caused by system deviations caused by internal events: component failures and/or operator errors.

The increased frequency of severe natural events as storms and floods, the increased number of facilities operating in harsh environments, and the changes in the global political framework, raised the interest on the prevention and protection of population and assets from major accidents caused by natural events or by intentional acts of interference.

The quantitative assessment of risk deriving from such scenarios requires the development of new and specific tools in a highly interdisciplinary framework. An approach to the problem will be presented. Equipment vulnerability models considering the impact of natural events and of improvised explosive devices were developed. The specific release scenarios that may be triggered by the impact of external events were identified and assessed. An approach to the estimation of the final consequences of such scenarios requires a specific approach, taking into account the possible failure of conventional safety barriers and the possible simultaneous impact of the triggering event on multiple equipment will be presented. The discussion will address also the approach to the assessment of cascading events resulting on the impact on the population, the interruption of lifeline services, and the disruption of community life.
