Process Safety with Trish & Traci

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 inclu...

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”  This book explores weak signals and focuses on how to identify and manage them to prevent incidents. It uses fun storytelling about the unique platy...

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 ...

When OSHA's Process Safety Management (PSM) standard took effect in 1992, it promised a new era of systematic hazard identification. Three decades later, process safety professionals are still witnessing the same critical oversights repeatedly compromising facility safety—oversights that have contributed to near misses, and far worse, major incidents.

Editor-in-Chief Traci Purdum reads an article from Felicia Miller, senior princip...

This episode explores the critical role of equipment reliability in chemical processing, focusing on three major incidents: Longford, BP Texas City and Buncefield. Trish highlights how faulty instrumentation, poor maintenance and overlooked management of change led to catastrophic failures, fatalities and environmental impacts. The discussion emphasizes safety-critical elements, maintenance KPIs and the importance of accurate instr...

In this episode, Trish Kerin and Traci Purdum discuss process safety insights with Alex Fernando and Warren Smith from Incident Analytics. Their research analyzed over 10,000 incidents across 12 countries and multiple high-risk industries.

Key findings include that organizations often misclassify serious incidents, missing critical learning opportunities. Many safety controls are "difficult" or "unworkable" in practice, with worker...

Mastering Tim Tam timing mirrors process safety's critical risk-reward balance. Get it right and you’ll reap rewards.

As the bickie became gooey in my fingers, I knew the moment was now — time to slam that Tim Tam.

A Tim Tam is an Australian bickie — or cookie, to those of you in the U.S. It was created in 1964 by Arnott’s and is an iconic Aussie treat. It consists of two rectangular bickies with a flavored cream filling that is co...

This 100th episode of "Process Safety With Trish and Traci" examines the 2003 Space Shuttle Columbia disaster through the lens of due diligence. Columbia disintegrated during re-entry after foam debris damaged heat shield tiles during launch. The podcast explores how NASA normalized foam strikes over time, turning "lessons of failure into memories of success." Multiple intervention opportunities were missed due to inadequate resour...

On a sunny summer day in 2007 near Wichita, Kansas, a tanker truck was offloading naphthalene into a stainless-steel tank at a solvent tank farm when the container spontaneously ignited, catching fire and exploding, shooting projectiles in the air. This led to the evacuation of thousands in a nearby community. While there were no casualties, the explosion destroyed the entire storage facility, luckily not causing any injuries or fa...

Risk assessment should still be a manual process, but AI can streamline data collection to enable sound engineering judgments.

In this episode,  Trish and Traci welcome guest Dheerajkumar Narang, whose research examines how AI and machine learning can enhance process safety compliance. Traditional compliance methods are time-consuming and fragmented across different systems, while AI can automate data collection, identify leading i...

In this episode, Trish and Traci discuss the catastrophic failure at Queensland's Callide Power Station C4 on May 25, 2021, which caused power outages for 470,000 people.  During a routine switching operation to replace DC battery systems, a voltage drop was misinterpreted as an AC fault, triggering a cascading failure. Both AC and DC systems failed, leaving the turbine without lubrication while it continued spinning backwards at 3...

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 “Wield Questions to Learn and Teach” 

“Curiosity killed the cat, but satisfaction brought him back.” – A proverb made modern by Eugene O’Neill.

Have you ever asked a question at work and were surprised by the answer? Over the course of my caree...

Remembering the human toll of Texas City and Deepwater Horizon and applying those lessons learned can prevent similar tragedies.

In this episode, Trish and Traci discuss two major BP incidents: the 2005 Texas City Refinery explosion that killed 15 workers when an overfilled tower created a geyser of hot raffinate that ignited, and the 2010 Deepwater Horizon explosion that killed 11 workers and caused the largest U.S. marine oil spi...

Have you ever done a double-take when looking at an inspection photograph? I certainly did when an engineer at a valve manufacturer sent me an inspection photograph and asked, “See anything wrong with this picture?” “Yeah,” I replied. Someone had installed two expansion relief valves back-to-back on the body bleed of a twin-seated plug valve used for isolation in our gasoline tank farm. The valve casting safety port was cracked bec...
