Process Safety & Functional Safety: A Tale of Two Disciplines

Recording Date: September 2025

Do you really understand the difference between “process safety” and “functional safety”?  This webinar will clear up the confusion as it applies to high-risk industrial environments such as chemical processing, oil and gas, and power generation. We'll start by exploring the key standards and guidelines that govern each discipline.

We'll then dive into a detailed comparison, reviewing the similarities and crucial differences between these two safety methodologies. The goal is to provide a clear understanding of how organizations can effectively integrate both process and functional safety strategies to manage hazards, prevent incidents like fires, explosions, and toxic releases, and ultimately create a more robust safety culture. Join us to learn how to correctly identify and apply these distinct but complementary disciplines for a safer operational environment.
