To legally obtain the authoritative document: 6. Actionable Recommendations for Author

1984: Mexico City: A series of explosions at an LPG terminal caused hundreds of deaths.

• Bridging qualitative (HAZOP) and fully quantitative risk analysis.
• Assigning PFD (Probability of Failure on Demand) to independent protection layers (IPLs).

6. Actionable Recommendations for Author

1. Add a one-page “QRA workflow checklist” as an appendix for practitioners.
2. Include at least two complete worked examples – one for a pressurized flammable release, one for a toxic release.
3. Provide a list of recommended software tools (e.g., ALOHA, PHAST, RISKCURVES) with their typical applications.
4. Review all failure rate data against CCPS’s “Guidelines for Process Equipment Reliability Data” (latest edition).
5. Correct minor typos (e.g., p. 34 “ignitation”, p. 82 “consequenece”).
