A HAZOP is only as good as its facilitator. We run node-by-node studies that find real hazards — and track actions to closure.
From study preparation through action close-out, we manage the entire HAZOP process so your team can focus on decisions — not logistics.
Node list development from P&IDs. Documentation package assembly. Study schedule and team selection guidance. Design freeze checklist. P&ID issue verification.
Structured HAZOP using IEC 61882 methodology. Guide word application: No, More, Less, As Well As, Part Of, Reverse, Other Than. Real-time documentation and cause/consequence capture.
Layer of protection analysis run concurrent with or after HAZOP. Initiating event frequency assignment. IPL credit verification. SIL target determination per IEC 61511.
HAZOP worksheet documentation to industry standard. Ranked action item register. Executive summary with key risk findings. Regulatory-ready format for PSM compliance.
Post-study action management system. Design response verification. Re-HAZOP of modified nodes. Action register maintained through detailed engineering and to close-out.
Existing process HAZOP revalidation (5-year PSM requirement). MOC-triggered partial HAZOPs. P&ID redline review and update. Deviation-from-design analysis.
Process hazard analysis is one of the 14 elements of 29 CFR 1910.119. HAZOP is the recognized methodology for complex continuous processes.
| PSM Requirement | HAZOP Deliverable | Timing |
|---|---|---|
| Process Hazard Analysis (§1910.119(e)) | HAZOP study and action register | Before startup; revalidate every 5 years |
| Process Safety Information (§1910.119(d)) | P&ID basis for HAZOP nodes | Complete before PHA |
| Pre-Startup Safety Review (§1910.119(i)) | HAZOP action close-out verification | Before introducing hazardous chemicals |
| Management of Change (§1910.119(l)) | MOC-triggered HAZOP re-study | Before implementing change |
