Hazard Identification and Risk Assessment (HIRA)

HIRA will typically address three main risk questions:

  • Hazard    – What can go wrong?
  • Consequences  – How bad could it be?
  • Likelihood    – How often might it happen?

HIRA’s play a pivotal role in managing risks and determining acceptability. They form the foundation for process safety management activities.

Once Hazards have been identified and associated risks assessed, the acceptability of the risk can be judged.

It’s critical that HIRA’s are carried out with the relevant expertise and knowledge of process safety requirements because inaccurate assessments will lead to vulnerability.

At Applied KPI, we have significant expertise in conducting Qualitative and Quantitative HIRA studies. We can also offer semi-quantitative HIRA studies to allow ease of prioritisation for critical actions identified.

Our HIRA approach comprises:

Hazard Identification

  • Select appropriate HIRA methods.
  • Gather appropriate data to identify and establish hazards. This is conducted using a variety of methods such as (but not limited to):
    • Interviews with key personnel
    • Site reconnaissance
    • Desktop studies (P&IDS, Design Reports etc)
    • Review of past incident records
  • Document any identified hazards for risk assessment.

Risk Assessment

Risk assessment involves considering the possible results of someone being exposed to a hazard and the likelihood of this occurring. Assessment techniques make use of risk tolerance criteria and can be Qualitative, Semi-quantitative or Quantitative. Applied KPI has expertise in the following techniques for Risk Assessment:

  • Hazard Identification Studies (HAZID)
  • Hazard Operability Studies (HAZOP)
  • Quantitative Risk Assessments (QRA)
  • Layers of Protection Analysis (LOPA)
  • Extensive range of workplace risk assessments (Task or Process Specific)
