Abstract

To carry out a detailed risk analysis usually requires an immense amount of time and manpower. This holds especially for quantitative risk assessment methods. In order to keep the necessary efforts as low as possible, it has turned out to be advantageous to use screening methods for the determination of preliminary assessments. These preliminary results shall facilitate the decision about the necessity of further, more detailed investigations. The most widespread methods for safety screenings are based on matrices or tables which include relevant expert knowledge. They are capable of producing sufficiently precise results for a preliminary risk assessment. However, the methodology and valuation procedure must comply with certain conditions, which are sometimes overlooked, and, therefore, not fulfilled. In this publication, general requirements for the development and verification of matrix methods, as used for the screening of process plants, are described.
