Use techniques like HAZOP or Checklist analysis to identify potential failure scenarios.
Meeting the stringent requirements of OSHA PSM or Seveso III directives. Conclusion
Because it is impossible to analyze every microscopic failure, analysts group potential failures into representative "loss of containment" (LOC) scenarios. Examples include: Catastrophic catastrophic vessel rupture. Full-bore pipe breaks. Small leaks in gaskets or valve packing. Loading/unloading arm failures. 3. Consequence Modeling Use techniques like HAZOP or Checklist analysis to
Once risks are quantified, they must be evaluated against established risk tolerance criteria to determine if risk reduction measures are necessary.

Societal risk evaluates the risk to a group of people or a community as a whole. It accounts for the number of people exposed to the hazard. Societal risk is typically expressed using an , which plots the cumulative frequency (F) of accidents causing N or more fatalities against N. Risk Evaluation and Decision Making
Mandates quantitative assessments for upper-tier hazardous establishments to ensure safety distances between industrial plants and residential areas. Key Benefits of Implementing CPQRA
What is the impact (e.g., fatalities, environmental damage, or financial loss) if that failure occurs? Core Components of the CPQRA Process
Determining what can go wrong (e.g., vessel rupture, pipe leak).
