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

By combining the frequencies of all possible scenarios with their respective consequences, the total risk is calculated. This is usually presented in two ways: CPQRA is a systematic methodology used to evaluate
