Identifying the process units, chemicals, and boundaries of the study.
CPQRA is a structured methodology used to identify potential incident scenarios and estimate their risk by combining (the "how bad") with frequency analysis (the "how often"). Unlike qualitative methods like HAZOP, CPQRA provides numerical data, allowing management to make objective decisions about where to invest in safety upgrades. Key Steps in the CPQRA Workflow Identifying the process units, chemicals, and boundaries of
