Process Hazard Analysis (PHA) Facilitation and Revalidation

Our personnel have provided PHA training on behalf of the AIChE Continuing Education Program for over 25 years.

We furnish strong and knowledgeable PHA facilitation support using a variety of techniques including Hazard and Operability (HAZOP) Study methods, What If?, What If?/Checklist, Failure Modes and Effects Analysis (FMEA), and Layer of Protection Analysis (LOPA).

Our methods are designed to clearly meet OSHA PSM and EPA RMP requirements and provide practical, risk-ranked safety, environmental, reliability, business, and security insights.

Our experience and procedures for PHA revalidations promote effective and time-efficient revalidation studies.


ePHATM is a versatile Microsoft® ExcelTM-based electronic tool we have developed for real-time PHA documentation that provides a flexible and convenient platform for PHA facilitation and documentation, using order-of-magnitude likelihood and severity categories.

Licenses for use of ePHA are made available to clients in conjunction with our PHA consulting services.
