Q&A
Long PHA workshops. Frustrated SMEs. Inconsistent hazard identification. Findings that don’t stand up to regulatory scrutiny.
In many cases, the root cause isn’t the facilitator, the team, or the methodology - it’s node definition that isn’t fully aligned with the study’s objectives.
If you’re responsible for process safety, operational integrity, or project delivery, this webinar will show you how practical node definition transforms the manageability, focus, quality, and efficiency of your PHA and HAZOP studies.
Drawing on extensive real-world experience facilitating PHAs, Fabio Silva breaks down how strong node structure sets the tone for focused discussions, sharper risk identification, and regulator-ready outcomes.
