How to investigate and assess combination of hazards

Operating experience from different types of industrial installations has shown that combinations of different types of different hazards occur during the entire lifetime of the installations. Typically site specific occurring hazards cause or induce other hazards to occur. In particular, natural hazards rarely happen alone. Thus, it is very important to note that almost any event combination of hazards is possible and that it is necessary to identify these interactions and find ways to mitigate the effects of hazard combinations. Therefore, it is a basic task to investigate and assess the relevant combination of hazards not only for a single installation but for the respective site/industrial park. In that context domino effects and cascade effects pose particular challenges for risk management to prevent industrial accidents.
