When economic pressures mount, safety vigilance can quietly erode — and that's when incidents happen. In this episode, process safety expert Trish Kerin introduces APTBED, a practical decision-making framework for navigating volatile, uncertain, complex and ambiguous times. The acronym covers six critical areas: Authority (know who's in charge), Psychological Safety (create space for honest information), Tacit and Explicit Knowledge (bring all knowledge into the room), Biases (recognize and manage cognitive blind spots), Expectations (manage them or people will fill the void), and Document Decisions (if it's not written down, it never happened). Good decisions and strong safety culture aren't mutually exclusive — even in a crisis.

AI agents are now so easy to build that almost anyone can create one, but easy access doesn't mean blanket permission. In this episode, Trish and Traci explore how agentic and generative AI can help chemical facilities by gathering data for risk assessments, spotting weak signals in process trends and freeing engineers from administrative work. They also cover the risks: hallucinated sources, rogue agents and company information leaking into public tools. Trish urges listeners to fix broken processes before automating them, keep risk assessments human-led and verify every output. The goal isn't to fear AI but to use it thoughtfully.
Our brains are wired to find meaning in incomplete information — even when there isn't any. Here's how that same shortcut that turns clouds into animals can turn ambiguous data into costly decisions, and the simple question that can snap you out of autopilot.
With federal OSHA down to roughly 1,700 inspectors for 12 million workplaces — meaning a facility might see a full inspection once every 191 years — self-regulation has effectively become the entire safety system. In this episode, Trish Kerin explains why internal teams stop noticing their own drift from procedure (normalization of deviance) and why "no incidents" doesn't mean a program is working — only that controls haven't been tested yet. She outlines practical fixes: cold-eyes audits between facilities, the three lines of defense model, and the crucial difference between assurance and reassurance. Her bottom line: good process safety isn't just compliance — it drives reliability, productivity and profit.
On this episode of Processing Safety with Trish and Traci, forensic engineer Dr. Sean Brady joins Trish Kerin and Traci Purdum to revisit Piper Alpha, the 1988 North Sea platform disaster that killed 167 workers. They trace how a lost permit-to-work, a missing relief valve, and a design never updated for gas service combined with failed firewalls, redundant systems that bred false confidence and risers that kept feeding the fire. Using the "Jenga tower" metaphor, Brady explains how safety systems degrade unnoticed until they collapse, and why organizations must dispense with likelihood and focus on consequence, controls, and leadership culture to prevent the next catastrophe.
Smart design and layout choices, made well before a crisis hits, can protect plants from cyberattacks, sabotage and extreme weather without a major capital investment.
