Management of change (MOC) is the cornerstone of a successful risk-based process safety (RBPS) program. Safe operation and maintenance of facilities that manufacture or store hazardous chemicals require robust process safety management (PSM) systems. The MOC element of RBPS program establishes a formal, documented authorization process to manage changes that may introduce unexpected new hazards or increase the risk of existing ones. Most companies have established MOC systems to evaluate and approve (or reject) proposed changes, leading managers and supervisors to assume that this PSM element is well in hand. Now that the MOC system is up and running, however, have you noticed "backsliding", complacency, or just going through the motions? Or, perhaps there is reasonably good usage of the system in your company, but you consider that there ought to be more value to be gotten from the MOC system data.
