Aramis: Powerful Methodology in Quantitative Risk Assessment of Chemical Industry Zones

Many chemical industry installations exist in chemical industry zone and catastrophic accidents may be caused if the primary accident expanded. ARAMIS(Accidental Risk Assessment Methodology for Industries System) is a systematic methodology to the process industry risk analysis and was proposed in the fifth Framework Program of the European Commission. The methodology is consisted of several sections. The first is the building of a methodology for the identification of major accident hazards (MIMAH), which is help to find the worst accidents likely to occur on the equipment. The second section is called methodology for the identification of reference accident scenarios (MIRAS) takes into account the influence of safety systems on both the frequencies and possible consequences of accidents. This section helps us to identify the more realistic accident scenarios. Vulnerability and risk distribution figure in the whole chemical industry zone will be achieved visually at last. The application of the methodology indicates that it offers an alternative to purely deterministic and probabilistic approaches to risk assessment of process plants and the results will provide the decision-making basis of land-using and emergency planning.
