Lebanon’s Single Most Destructive Explosion – Terrorists Plan to Copy and Provision against Such Accidents

Abstract Explosives continue to be the primary tactic used by terrorists across the world and given the high security risk faced by mega infrastructure, a systematic security risk assessment framework is proposed in this paper. Classification and rating criteria are established for this framework pertaining to threat/vulnerability and impact/consequence assessment, based on which asset risk rating can be calculated. The proposed risk assessment framework refines the author’s previous work of risk rating criteria and evaluates risks in both qualitative and quantitative ways. Risk ratings are classified both numerically and in color codes for the ease of analysis and application. This framework is validated in a case study of risk assessment of a mega infrastructure facility and can support further risk management and investment policy. A case study of a chemical facility utilizing the risk assessment framework is provided.
