In change management, a temporary change that will be restored to the original state must still go through Management of Change (MOC) activation.

• A. True
• B. False
• C. Depends on duration
• D. Not required if temporary

Answer: (B)

Understanding how changes are reviewed in process safety shows that not every temporary reversal requires a full Management of Change review. MOC is used to authorize changes that affect how the process operates or its hazard profile. If a change is truly temporary and will be restored to the original state, many facilities manage it with a separate mechanism—such as a temporary deviation or permit-to-work—that keeps risk under control without going through a full MOC process. This works when the change does not introduce new hazards, does not alter safety instrumented systems or fundamental operating envelopes, and has a clearly defined duration and rollback plan.

The important caveat is that the decision hinges on policy and risk. If the temporary change could affect process safety, or if it interacts with existing safety controls or the hazard analysis, then a full MOC review would still be appropriate. In short, a temporary change that will be reversed is not universally required to go through MOC activation; many organizations permit an alternative, risk-managed route for brief, reversible changes.
