Often process safety incidents have occurred when an activity has deviated from the expected path, but those involved have continued anyway or informally adapted the plan on-the-run. While this may be well-intended, to get the job done, it has the potential to lead down a path that has not been fully evaluated and risk assessed.
This process safety fundamental highlights the importance of recognising when things are not progressing as expected and being disciplined about stopping or pausing to understand what has changed and why things are not as planned.
