Speaker notes
Welcome to Chapter 1. The goal here is to set the foundation for everything that follows in the book. We’ll start by separating process safety from occupational or personal safety, because confusing these two creates distorted priorities. From there we’ll define the core language you’ll use every day—major accident hazards, loss of primary containment, hazards, risks, and barriers.
As we move through the chapter, we’ll use a simple scenario chain—from hazard present, to an initiating threat, to a loss of containment, to escalation and harm—to show where prevention and mitigation actually work. Finally, we’ll translate the concepts into the day-to-day role of a Process Safety Engineer: not as the ‘owner’ of every safeguard, but as the integrator who keeps the hazard picture current, challenges weak assumptions, and protects barrier integrity across operations, maintenance, projects, and leadership. On each slide, focus on the logic and the practical implications, not just the definitions. Next we’ll start with the chapter intent and what success looks like.
