What safety models and principles can be adapted and used in security science?

Engineering risk management is comprised of managing operational safety risks on the one hand and managing physical security risks on the other. Although some basic management principles are obviously the same for both safety and security, some important conceptual and calculation differences exist, as is explained in this paper. For instance...

Cost-effective fire protection of chemical plants against domino effects

The propagation of fire-induced domino effects in chemical plants largely depends on the primary fire scenario, on separation distances between the units, and on the presence of fire protection barriers. Passive and active safety barriers are widely employed to prevent or delay the initiation or propagation of domino effects. In the present...

Applying agent based modelling and simulation for domino effect assessment in the chemical industries

The propagation of accidents among process units may cause amplification of accident magnitude, resulting in a domino effect chain. Several catastrophic accidents occurred in the process and chemical industry presented these features. Hence, research efforts have been given to the analysis of the domino effects in order to enhance prevention...

Application of dynamic Bayesian network to performance assessment of fire protection systems during domino effects

The propagation of fire in chemical plants – also known as fire domino effects - largely depends on the performance of add-on passive and active protection systems such as sprinkler systems, water deluge systems, emergency shut down and emergency blow down systems, fireproofing, and emergency response. Although such safety barriers are widely...

Application of graph theory to cost-effective fire protection of chemical plants during domino effects

In the present study, we have introduced a methodology based on graph theory and multicriteria decision analysis for cost-effective fire protection of chemical plants subject to fire-induced domino effects. By modeling domino effects in chemical plants as a directed graph, the graph centrality measures such as out-closeness and betweenness...

Probabilistic vulnerability assessment of chemical clusters subjected to external acts of interference

Acts of interference against chemical facilities or chemical clusters might result in severe consequences in case of a successful attack (major explosions, fires, toxic dispersions or environmental contamination). Although process facilities implement multiple safety barriers to control process hazards that may result in major accidents and...
