Embedding ISD findings into HAZOP, LOPA, and risk assessment workflows
ISD integration ensures inherent safer alternatives are systematically considered for every HAZOP and LOPA finding. We design workflow, train facilitators, and provide ISD challenge across the risk assessment process.
Conduct pre-HAZOP ISD workshop per CCPS Guidelines for ISD — review process flow / P&IDs for ISD opportunities (minimise / substitute / moderate / simplify) before HAZOP node walk-through; capture early ISD options in design register.
Integrate ISD lens into HAZOP node-by-node review — for each deviation, ask 'can we eliminate the hazard inherently?' before adding engineering safeguards; document ISD options alongside conventional safeguards in HAZOP worksheet.
Classify HAZOP recommendations per CCPS — ISD (eliminate hazard), Engineered Safeguard (reduce risk), Procedural (administrative control); prioritise ISD over engineered, engineered over procedural per hierarchy of controls.
Apply ISD credit in LOPA — eliminate scenario where hazard is removed inherently, reduce frequency where ISD modifies likelihood, reduce consequence where ISD moderates outcome; align with IEC 61511 / CCPS LOPA methodology.
Track ISD recommendations through implementation per HAZOP action register; require MOC review for any ISD action de-scoping; align with PHA close-out tracking and CCPS RBPS Process Safety Culture element.
Conduct annual ISD programme maturity assessment per CCPS framework — leadership commitment, technical capability, design / operations integration, learning culture; benchmark against industry peers via RCMI / ICCA.
Complete ISD Integration with HAZOP and Risk Assessment scope — every calculation, drawing, specification, and construction support activity.
