All elements of process safety management (PSM) are important, and they all interact with one another. However, it is suggested that three of the elements are of particularly high importance. They are employee participation, hazards analysis and management of change (MOC).
- Safety Moment #66: The Most Important PSM Elements — Participation,
- Safety Moment #67: The Most Important PSM Elements — Management of Change (this one), and
- Safety Moment #68: The Most Important PSM Elements — PHAs.
With regard to MOC, many of the articles and safety moments at this site are to do with Management of Change. They include:
- Safety Moment #5: Management of Change — Defining Change;
- Safety Moment #50: Temporary Change (both in the ebook 52 Process Safety Moments); and
- Safety Moment #59: In-Kind/Not In-Kind Change.
This focus on MOC is intentional. After all, most incidents take place because someone, somewhere made a change such that process conditions were moved outside the safe limit values. If change can be managed properly then the number and severity of incidents will decline dramatically.
