Risk Assessment

For the continued safe operation of an establishment with possible major accident hazards, it is vital that an operator understands the risks posed by operations to people and the environment. There are many tools available to determine risk, though the tool used needs to be appropriate and proportionate. Furthermore, risk assessment is a powerful management tool that, if used correctly, can help identify hidden weakness and direct spend into priority areas.

Our process safety specialists use these tools every day, helping clients in decision making to ensure the right measures are in place for prevention, control and mitigation. This not only applies to plant and process design but to development of the management systems and procedures necessary for continued safe operation.

In short, we can help you to:

  • Understand which tools and techniques can best be used to identify improvements
  • Use cost benefit analysis to evaluate and substantiate cases for funding
  • Implement robust processes for effective risk management

We can provide guidance, facilitation and support for the following:

  • Inherent safety reviews of processes and processing equipment (“HS0”)
  • Hazard identification studies, e.g. HS1 (What-If?), HS2 (HAZIDand HS3 (HAZOP)
  • Failure Mode & Effects [and Criticality] Analysis (FMEA and FMECA) studies
  • Layers of protection analysis (LOPA) and SIL determination
  • Task analysis and human reliability analysis (HRA)
  • Dangerous Substances Explosive Atmospheres (DSEAR) risk assessment including Hazardous Area Classification (HAC)
  • Fire risk assessment (FRA)
  • Quantified risk assessment (QRA/semi-QRA)
  • Occupied buildings risk assessment (OBRA)
  • ALARP demonstration, including Further Risk Reduction Measure (FRRM) studies, Past Accident Reviews (PAR) and Cost Benefit Analysis (CBA)
  • Flood hazard identification studies (FHIS) and flood risk assessment
  • Environmental risk assessment (ERA)
