Modelling of risk for occupational accidents

Occupational injuries area significant threat to the safety of personnel working at the petroleum installations on the Norwegian Continental Shelf. However, occupational injuries are seldom systematically applied as a basis for design and operation. Instead, risk is generally assessed in terms of Quantitative Risk Analyses (QRAs), which measure risk by Fatal Accident Rate (FAR). Thus, there is a need for applying risk-based decision making with respect to occupational injuries. The objective of the study reported in this paper was to develop a framework for modeling the risk for occupational injuries. The study consisted of (1) a review of existing QRAs and available injury statistics, and (2) a multidisciplinary workshop, with the purpose of generating ideas on how to model the risk for occupational injuries. The outcome of the study is a general approach to how risk for occupational injures can be modelled.
