The correct answers are A and B because CCPS defines Management of Change (MOC) as a systematic process applied to all process-related changes across the lifecycle of a facility .
Option A is correct because MOC is specifically required for process-related changes , including modifications to equipment, chemicals, technology, procedures, and operating conditions. These changes can introduce new hazards or alter existing risks, making formal review essential.
Option B is also correct because MOC applies throughout the entire process lifecycle , including design, construction, operation, maintenance, and decommissioning. CCPS emphasizes that changes can occur at any stage, and each must be evaluated for safety impact.
Option C (replacement in kind) is incorrect because true replacement in kind-where there is no change in specifications or function -does not require MOC. However, careful verification is needed to confirm it is truly identical.
Option D is incorrect because confirming operational readiness is part of Pre-Startup Safety Review (PSSR) , not MOC itself. Option E relates to auditing or compliance activities , not the purpose of MOC.
CCPS highlights that effective MOC ensures all changes are reviewed, authorized, and safely implemented , preventing unintended consequences.
