We've heard it before and it is a common thread. Incidents have different decades, different chemicals, different industries, same root cause: a change that wasn't properly identified, reviewed, documented, or communicated. 1.Stop treating MOC as paperwork - It is the management system that prevents uncontrolled change from becoming unacceptable risk. 2.Recognize the pattern repeats across all contexts - Imperial Sugar was a dust explosion from conveyor modifications; MOC applies far beyond classic PSM chemical processes. 3.Audit your program against recurring failure modes - Unmanaged temporary change, ignored organizational change, inadequate hazard review, and incomplete documentation/PSSR.
