The assessment of risk in industrial installations : the risk severity index

摘要: A risk index (Risk Severity Index, S) has been devised to allow the assessment of level originated by a given installation or site over affected zone. set threshold levels for thermal radiation, toxic concentration, and overpressure, together with probabilities frequencies associated critical events their effects, have basis calculating values S. computer tool designed perform quick calculation diverse Risk Indexes (for event, dangerous phenomenon, type effect whole installation) plot map severity around site. The methodology applied test cases it proved be useful assessment, comparative studies land use planning.
