About Us

What is process hazard analysis?

Process Hazard Analysis (PHA) or Hazard Identification & Risk Analysis (HIRA) is a vital method aimed at identifying and evaluating potential risks associated with the handling and processing of hazardous materials. Using different hazard identification techniques will help your team recognize and understand the major accident hazards associated with your operations. PHAs/HIRAs come in various forms, ranging from qualitative to semi-quantitative and fully quantitative approaches, all designed to furnish crucial information to enhance safety decisions for workers and employers.

Commonly used process hazard analysis techniques include:

  • Hazard and operability (HAZOP)
  • Layer of protection analysis (LOPA)
  • Event tree
  • Fault tree
  • Bow-tie analysis
  • What-if and structured what-if (SWIF)
  • Failure mode and effects analysis (FMEA)
  • Quantitative risk assessment (QRA)
