Process Hazard Analysis

Our industry and regulatory leading PHA facilitators have extensive experience from having facilitated hundreds of PHAs.  Our PHA facilitators utilize the latest methodologies while providing vast insight and knowledge of known industry hazards.  Our team understands how to apply risks tolerance criteria and help facilitate critical evaluations to allow our clients to properly apply and utilize available resources.  PSS recognizes that applying the most appropriate risk identification and evaluation techniques is critical to hazard assessment, evaluation, and mitigation of risk.  Our PHA facilitation industry experience includes oil and gas processing, specialized chemical, petrochemical, ammonia refrigeration, as well as other unique processes. We deliver a quality, comprehensive, and robust PHA study that enhances our client’s overall Process Safety Management program.

In an average facility, there will be potentially hundreds, if not thousands, of hazards related to materials used, the technology used to process them, and the procedures followed to operate the plant. Management of the hazards and the risk associated with them can be overwhelming, and it can be very easy to misplace the focus.

In the past, it was very common to assess risks using a qualitative approach, such as a risk matrix. More frequently however, risks are assessed using a semi-quantitative process such as Layers of Protection Analysis (LOPA) as a whole, or more common, just assessing those hazards that pose a “high risk”. Risks can also be measured using a Quantitative Risk Assessment (QRA).

The techniques that Process & Safety Solutions LLC (PSS) utilize to assist in the identification and analysis of hazards include:

  • Hazard and Operability Study (HAZOP)
  • Hazard Identification Study (HAZID)
  • Layer of Protection Analysis (LOPA)
  • What-If
  • Checklist
  • Qualitative Risk Assessment
  • Safety Integrity Level (SIL) Assessment & Verification
