ISD Integration with HAZOP and Risk Assessment
We embed inherent safer design findings into your HAZOP, LOPA and risk assessment workflows
ISD Integration with HAZOP
and Risk Assessment
Inherent safer design is most powerful early and most neglected late. The four strategies of minimise, substitute, moderate and simplify are typically debated once at concept selection and then forgotten as the project hardens around added protection. Integrating inherent safer design into the HAZOP and LOPA workflow keeps the question alive at every node, so that before a new alarm, trip or relief device is credited, the team is required to ask whether the hazard can instead be removed or reduced at source. Our team designs the procedural hooks and recording fields that capture inherent safer design challenges as first class findings, trains your facilitators to drive the hierarchy of controls discipline rather than default to engineered safeguards, and makes sure inherent options are evaluated with the same rigour as the protection layers they could displace.

ISD Integration with HAZOP and Risk Assessment workflow
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.
