HAZID — Hazard Identification

A structured process for identifying hazards associated with facilities, operations or projects before they result in incidents.

Definition

Hazard Identification (HAZID) is a systematic risk assessment methodology used to identify potential hazards throughout the lifecycle of industrial facilities, projects and operations. HAZID workshops bring together multidisciplinary teams to identify hazardous scenarios, evaluate potential consequences and recommend risk reduction measures at an early stage of design or project development.

Why It Matters

HAZID provides an early understanding of project risks and supports inherently safer design by identifying hazards before detailed engineering or construction begins.

In Practice

HAZID studies are commonly performed during concept selection, front-end engineering design and major project modifications to establish the project's risk profile and define follow-on safety studies.

Common Misuse

HAZID is a broad hazard identification exercise performed early in a project, whereas HAZOP is a detailed, guideword-based review of completed process designs.
