When natural disasters strike industrial facilities, the results can be catastrophic — and most companies aren't ready. In this episode of Process Safety with Trish and Traci, Trish Kerin and Traci Purdum explore NATECH events, where natural hazards collide with industrial risk. Drawing on real incidents including Arkema in Crosby, Texas, BioLab in Lake Charles and the Fukushima disaster, they examine why facilities consistently underestimate natural hazard risk, how to build truly complete ride-out and recovery plans, and why traditional PHAs fall short for NATECH scenarios. Kerin's bottom line: assume the event will happen, and prepare accordingly.

Chernobyl, Bhopal, Three Mile Island, Deepwater Horizon, Texas City — What do they have in common? Human error or human factors were identified as contributing to the incidents. But what are these factors?

Understanding how people actually perceive, decide and act is essential to preventing catastrophic industrial accidents and everyday errors.

In this episode, Trish Kerin and Traci Purdum explore process hazard analysis revalidations and how to make them more effective. Kerin explains the difference between redoing a PHA and revalidating existing assessments, introducing the Delta HAZOP methodology that focuses on creeping change in facilities. She discusses triggers for revalidation, from legislative requirements to significant operational changes, and emphasizes the importance of selecting the right team and methodology. Kerin highlights how AI and machine learning can help gather data and identify trends, while stressing that human expertise remains essential. The key takeaway: approach revalidations with rigor and discipline, not as tick-box exercises, to truly identify hazards and manage risk effectively.

This In Case You Missed It episode brings the written word to life. Today, Trish Kerin, the director of Lead Like Kerin, and Stay Safe columnist for Chemical Processing, will read her column "Bird’s-Eye View Prevents Process Safety Groundings," which was published to chemicalprocessing.com on Dec. 17, 2025.

In this year-end episode, hosts Trish Kerin and Traci Purdum welcome Hayley Little, a U.K.-based process safety engineer who tracks quarterly catastrophic incidents on LinkedIn. The discussion explores origin stories in process safety, the critical gap in fundamental safety knowledge outside petrochemical industries, and the alarming frequency of preventable incidents in lower-hazard sectors. They discuss innovative solutions including AI tools, virtual reality training and social media outreach to democratize process safety education. The conversation emphasizes the urgent need for better university training, field presence over desk work and human factors integration to make it easier to "accidentally get it right."

This In Case You Missed It episode brings the written word to life. Today, Trish Kerin, the director of Lead Like Kerin, and Stay Safe columnist for Chemical Processing, will read the first few chapters from her book  “The Platypus Philosophy – how to identify and manage weak signals” 

The Buncefield explosion occurred when a gasoline storage tank overfilled after both its level gauge and independent high-level switch failed. Gasoline vapor formed a massive cloud that ignited, causing significant damage to surrounding business parks. Fortunately, the Sunday morning timing prevented fatalities, though 43 injuries occurred. The incident revealed critical gaps in safety control verification, testing procedures, and maintenance regimes. Twenty years later, the disaster emphasizes the importance of recognizing weak signals, maintaining bund integrity, and ensuring operators actively monitor tank filling operations rather than relying solely on automated systems.
