This information sheet provides information on human factors for operators to consider in their hazard and operability analysis (HAZOP) processes. HAZOP is a widely used and comprehensive method for process safety in major hazard facilities and petroleum and geothermal energy operations. The result of a HAZOP is a set of identified process hazards and list of actions to mitigate these.

The document covers human factors within the system: the individual, the job and the organisation and provides information on how those factors influence a HAZOP and advice on how to mitigate these influences.
