Definition - What does Hazard Identification Study (HAZID) mean?

A hazard identification study (HAZID) is the procedure used for hazard identification in workplace health and safety. It is conducted by breaking down all processes in a worksite for detailed analysis. Once a hazard is identified, the hazard identification study reviews the effectiveness of the selected measures and expands the safety measures where required to reach a tolerable residual risk.

WorkplaceTesting explains Hazard Identification Study (HAZID)

The analysis revealed by the hazard identification study serves as a proof that the installations are operated under safe measures where employees, third parties, the environment, and the surroundings are excluded from hazardous conditions. The key benefits of a hazard identification study include:

  • Identification of hazards and safeguards at early stages in facility design
  • Health, safety and environment hazards are revealed before significant costs are incurred
  • Hazards are avoided, mitigated or highlighted during design
  • Action responses are auditable
  • Design and construction delays are avoided
  • Fewer hazards remain unidentified during operation
