Find the Right Hazard Study for Your Project

Not sure if you need HAZID, HAZOP, or a broader hazard analysis and risk assessment? Answer a few quick questions and we’ll guide you to the right assessment.

When safety decisions impact people, plant, and performance, choosing the correct methodology matters. Our guided assessment helps you determine whether a HAZOP, HAZID, or a targeted hazard identification and risk assessment (HIRA/HARA) is appropriate for your design stage and risk profile.

Why this assessment

  • Match the study to your lifecycle stage (concept, design, pre-start, operation)
  • Clarify when to run a full HAZOP analysis vs. an early-stage HAZID
  • Identify gaps that a focused hazard analysis and risk assessment can close
  • Get practical next steps and an expert follow-up if needed

What you’ll get

  • A recommendation (e.g., HAZOP assessment, HAZID workshop, or blended approach)
  • Typical scope, inputs, and outputs for that study
  • Estimated duration and team roles (operators, process engineers, facilitators)
  • Optional call to refine scope and schedule
Built by DEKRA specialists to simplify early scoping and improve study readiness.

Who is it for?

This tool is designed for teams in sectors the following sectors: Oil & gas • Chemicals • Pharmaceuticals • Energy & Utilities • Food & Beverage • Manufacturing • Logistics & Warehousing, across the project lifecycle:
  • Design & Engineering Teams Move seamlessly from concept to detailed design with the right hazard review at each gate.
  • Operations & Plant Managers Validate existing units with Revalidation or Delta HAZOP, or confirm readiness with PSSR.
  • EPCs & Project Leads Align clients and contractors on scope, deliverables, and timing to keep complex projects on track.

HAZOP vs HAZID — what’s the difference?

HAZID: Early-stage hazard identification to surface significant hazards, external threats, and scenario families when detail is limited.
HAZOP: Systematic, guideword-driven review of a defined process to find deviations, causes, consequences, and safeguards, ideal once P&IDs and operating intent are mature.
When to choose which? Use HAZID to scope risks and target effort early; use HAZOP analysis to rigorously challenge design and operating envelopes before commissioning. Our tool helps you decide.

When a broader hazard analysis and risk assessment (HIRA/HARA) fits best

For complex operations, or where multiple modes (start-up/shutdown) and human factors are critical, a tailored hazard analysis and risk assessment can integrate findings from HAZID/HAZOP and prioritise mitigations with risk ranking.
How it works
Built for safety, designed for clarity
This tool guides you to an indicative study type based on typical inputs at each maturity stage. Complex or hybrid cases may need a short scoping call.

FAQs
Do I need a HAZOP or HAZID?
Use HAZID early to identify major hazards and shape scope. Choose HAZOP when your design is mature enough for a detailed, guideword-based review. Our assessment clarifies the best fit.
