There are several levels of risk-based assessments, usually described as qualitative, semi-quantitative, and quantitative. These vary considerably in the amount of effort and input needed and the accuracy of the resultant assessment. The qualitative assessment is usually performed to determine risk associated with whole or large portions of process units. The semi-quantitative and quantitative assessments are usually performed to determine risk associated with individual equipment items. (reference)
