Approaches for Risk Assessment Method Selection Criteria

Abstract

In safety engineering there are several risk assessment methods ranged from simple to complex, quantitative or qualitative and semi-quantitative. May be researchers or experts they need to answer the question: (which method we choose and why?). It may sometimes be necessary to employ more than one method of assessment. Two approached conducted the first approach discussed the selection of risk assessment method in consideration of availability of resources, uncertainty and factors influencing method selection. While the second approach discuss the selection criteria accordance of consequence assessment and frequency assessment. It found that the selection of methods affected mainly by environment under consideration. After this analysis it is suitable to conduct the risk assessment for the case study by using HAZOP as qualitative methodology and for quantitative FTA will be conducted. It is possible to mix the two approaches to form one model for selection process.
