== Bowtie diagrams for high risk hazards ==
It is not possible to make bowtie diagrams for all existing hazards. There are simply too many hazards, and it will take too much time to make as many bowtie diagrams. Moreover, it is less beneficial to create bowtie
diagrams for simple or low impact hazards, because structuring these hazard (by making bowtie diagrams) will not provide a much better understanding of the hazard (assuming these hazards will have a relatively simple structure). Therefor a separation should be made between high priority hazards that require bowtie analysis and low priority hazards for which only a HAZID analysis is sufficient. The HAZIDs inherent risk assessment levels can be used to assess which hazards require closer examination by creating bowtie diagrams.
