The assessment of hazards related to domino accidents is an important issue in the safety analysis of an industrial site. Several methodologies exist and different levels of detail may be used in the analysis. The present section provides a framework and a classification of the available techniques that may be used for domino assessment. Three approaches having a different level of detail are outlined and linked to needs and/or specific phases of process safety assessment. Criteria for the selection of the most appropriate approach are also discussed.

The complexity of domino scenarios represented a considerable obstacle to the quantitative assessment of risk posed by escalation events. In the present chapter, the state of the art concerning quantitative approaches proposed for the assessment of risk caused by domino accidents is summarized. A procedure for the quantitative risk assessment of domino accidents, suitable for the calculation of individual and societal risk indexes, is outlined. Alternative approaches proposed for the quantitative assessment of domino effects, based on Bayesian techniques and Monte Carlo simulations, are also described.

Domino effects may cause more severe accident scenarios in the chemical and process industries. An introduction is given to the context and state of the art of technical and scientific knowledge concerning accident scenarios where domino effect(s) took place, as well as to European regulations on the subject. The specific context of chemical clusters with respect to safety and security assessment when dealing with domino scenarios is also introduced.

This book provides insight into domino effects in industrial chemical sites and process industries. It is about the integration of safety and security resources to prevent and mitigate domino effects in the process industries. It explains how chemical industrial areas, comprised of various hazardous installations, are susceptible to a chain of undesired events, or domino effects, triggered by accidental events or intentional attacks and then presents solutions to prevent them. Firstly, the book provides a dynamic graph approach to model the domino effects induced by accidental fire or intentional fire, considering the spatial-temporal evolution of fires. Then, a dynamic risk assessment method based on a discrete dynamic event tree is proposed to assess the likelihood of VCEs and the vulnerability of installations, addressing the time dependencies in vapor cloud dispersion and the uncertainty of delayed ignitions. A dynamic methodology based on dynamic graphs and Monte Carlo is provided to assess the vulnerability of individuals and installations exposed to multi-hazards, such as fire, explosion and toxic release during escalation events. Based on these domino effect models, an economic approach is developed to integrate safe and security resources, obtaining the most cost–benefit protection strategy for preventing domino effects. Finally, a resilience-based approach is provided to find out the most cost-resilient way to protect chemical industrial areas, addressing possible domino effects. This integrated approach will be of interest to researchers, industrial engineers, chemical engineers and safety managers and will help professionals to new solutions in the area of safety and security.

The diverse historical surveys on accidents involving domino effect have been analyzed to identify their significance and their most important features. From these data, the importance of domino effect among all accidents in the process industry and in the transportation of hazardous materials has been highlighted. The characteristics of this type of accidents have been studied with a statistical approach: origin and causes of domino effect, materials most frequently involved and effects and consequences of accidents. The significance of the diverse domino sequences have been assessed by using the relative probability event tree. Finally, four relevant cases have been discussed, corresponding to the following initiating events: two vapor cloud explosions (Buncefield, 2005 and Naples, 1985), one jet fire (Valero, 2007) and one accident associated with dust explosion.

Managing domino effects in an industrial area is not an easy task. It requires multidisciplinary knowledge and know-how, an adequate mindset, eye for detail and for the big picture, a short-term as well as a long-term vision, thorough collaboration efforts, a generalistic perspective with specialist knowledge, and so on. Different domains need to be dealt with in relation to domino effects: technological issues, procedural requirements, and human factor topics. This chapter describes for each of these domains how they should be viewed with respect to internal and external domino effects, and provides recommendations on how management may/should tackle risks related to possible domino effects within a chemical industrial park.
