Guidelines for Chemical Process Quantitative Risk Analysis (CPQRA)
CPQRA is a systematic methodology used to evaluate the risks associated with the handling, processing, and storage of hazardous chemicals. Unlike qualitative assessments (like HAZOP), which describe risks in terms of "low" or "high," CPQRA produces numerical estimates. The CPQRA Equation
