HAZID (Hazard Identification) is a systematic process for identifying potential hazards in facilities, processes, and operations before detailed design. These structured workshops bring multidisciplinary teams together to proactively identify risks, enabling design modifications and safeguards that prevent incidents.

HAZID examinations consider equipment failures, human errors, external events, and hazardous material releases that could harm personnel, damage assets, impact environment, or disrupt operations. Facilitators guide teams through systematic evaluation using checklists, what-if scenarios, and experience-based insight.

For pressure vessel and process equipment projects, HAZID identifies hazards associated with equipment design, pressure relief requirements, material selection for safe operation, inspection and maintenance access, and emergency scenarios. Findings inform design improvements, safety system requirements, and operating procedure development.

Effective HAZID requires diverse perspectives—process engineers, mechanical designers, operations representatives, safety specialists—to capture full hazard spectrum. Documentation captures identified hazards, potential consequences, existing safeguards, recommendations for additional risk reduction, and action tracking.
