Abstract Quantitative risk assessment (QRA) methodology for industrial process plants was studied and compared with accident theory and accident experience drawn from various accident databases. Analysis of the data indicates that the proportion of accidents occurring when the plant is in some abnormal state may be 40% or more. Maintenance appears to be a particularly frequent abnormal state. It is recommended that maintenance operations be considered in all cases where the QRA is to be used for producing recommendations for risk reduction. Contents of this research report: description of QRA methodology; use of failure data in QRA; uncertainty and quality in QRA; QRA studies; QRA and accident theory; analysis of major accidents based on accident database information.
