HAZID
Catch major hazards at concept stage, when design changes are cheapest to make.
Early-stage hazard identification study performed at concept or pre-FEED stage to flag major hazards before detailed design.
Request a ConsultationWhat is HAZID?
Hazard Identification (HAZID) is a qualitative risk assessment technique conducted early in a project's lifecycle — typically at concept or pre-FEED stage — to identify major hazards associated with the proposed facility, site location, and surrounding environment before detailed engineering begins.
Why It Matters
- ●Influences site layout, spacing and inherently safer design decisions while changes are low-cost
- ●Provides input to land-use planning and emergency response zoning
- ●Required by many EPC contracts and lender due-diligence (equator principles) processes
- ●Reduces the chance of late-stage HAZOP findings requiring expensive design rework

FAQ
HAZID Frequently Asked Questions
What is a HAZID study?
HAZID is an early-stage, qualitative hazard identification exercise performed at concept or pre-FEED stage to identify major hazards related to a facility, its site, and surrounding environment before detailed design locks in key decisions.
What is the difference between HAZID and HAZOP?
HAZID is performed early (concept/pre-FEED) at a coarse, facility-wide level to catch major hazards and inform layout; HAZOP is performed later, once P&IDs exist, and examines deviations node-by-node in much finer detail.
When should a HAZID be conducted?
Ideally during concept selection or pre-FEED, before site layout and major equipment placement decisions are finalized, so that inherently safer design changes remain low-cost.
