On-Demand Webinar: Process Hazard Analysis (PHA) Revalidations
Understanding Types, Purpose & Compliance Considerations
11:00 AM (EDT) Thursday, June 19, 2025
Process Hazard Analysis (PHA) revalidations are a regulatory requirement under OSHA’s Process Safety Management (PSM) standard—29 CFR 1910.119—mandating a thorough review of existing PHAs every five years. The purpose? To verify that all process safety elements remain accurate, complete, and effective in managing risks.
In this PHA revalidation webinar, we’ll break down the fundamentals of conducting a revalidation, explain the different types used in industry, and clarify how to approach a PHA revalidation to meet regulatory requirements.
You’ll learn how PHA revalidations help address gaps such as outdated process data, unresolved recommendations, incomplete Management of Change (MoC) records, and missed incident learnings—all of which can undermine process safety performance.
What You’ll Learn in the PHA Revalidation Webinar
Why Revalidations Are Required: Understand the regulatory requirements of revalidation.
Types of Revalidations and When to Use Them: Determine how the difference types of revalidation are defined and when to use them.
Essential Elements of a Revalidation: Explore what should be reviewed during a revalidation, including:
Process changes and associated MoCs
Status of previous PHA recommendations
Completed incident investigations and corrective actions
New technology or updated process knowledge
Omissions and Deficiencies in Previous PHAs
New Requirements; Local, Federal, OSHA or SEVESO
Common Omissions and Pitfalls: Identify typical gaps not included in previous PHAs—such as outdated documentation or missing hazard scenarios—and learn how to address them effectively.
Complementary Studies and Updates: Learn which related risk assessments may also need to be revisited with the PHA to maintain consistency and regulatory readiness, including:
Facility Siting
Human Factors
Procedures &
Control Systems.
