Process Safety Management - PHA & LOPA Analysis

Orbital’s Process Safety Management service line covers all 14 Elements of the OSHA 1910 PSM Standard, although our core focus is on the following six elements: Process Safety Information (PSI), Process Hazard Analysis (PHA), Operating Procedures, Mechanical Integrity, Management of Change (MOC), and Compliance Audits. 

For a client in the Chemical industry, Orbital was contracted to perform a Revalidation PHA of the client’s Reactor processes.  The scope of work included a review of the previous PHA to first determine if the PHA could be revalidated in accordance with the 29 CFR 1910.119(e)(3) requirements.  A review was performed to verify that modifications to the process were accurately documented since the last PHA, following Management of Change procedures.  Incident investigation reports, existing PSI, and action items from the initial PHA were also reviewed.  After conducting the on-site PHA sessions in accordance with the client’s internal procedures, a report summarizing the results and recommendations from the analysis was delivered to the client.  This PHA was completed using PHAWorks as requested by the client, although Orbital has the capability of using other PHA software, such as PHA Pro.  This initial PHA revalidation has led to several additional revalidation for the client at that site in addition to other plant locations.
