Health- Safety and Environmental Risk Assessment of Refineries Using of Multi Criteria Decision Making Method

Growing importance of environmental issues at global and regional levels including pollution of water, air etc. as well as its outcomes such as global warming and climate change has been led to consider environmental aspects as effective factors for power generation. Study ahead aims at examination of risks resulting from activities of Refinery located in Iran. Method used in this research is analytical hierarchy process. After identification of factors causing risk, the analytical hierarchy structure of the Refinery risks were designed as well as weight of criteria and sub-criteria were calculated by intensity probability product using Eigenvector Method and EXPERT CHOICE Software. Results indicate that in technological, health-safety, biophysical and socio economic sections of the Refinery, factors influenced by the Refinery activities like fire and explosion, hearing loss, quantity of groundwater, power generation are among the most important factors causing risk in the Refinery. Groundwater level drop is the most important natural consequence influenced on Refinery activities.
