Which term describes the formal process of evaluating and authorizing changes to process technology to prevent new hazards?

• A. Change Control
• B. Change Management
• C. Process Modification
• D. Management of Change

Answer: (D)

The main idea is that any change to process technology must go through a formal review and approval to prevent creating new hazards. This is called Management of Change. It envelopes the full lifecycle: proposing the modification, conducting hazard and risk assessments, obtaining appropriate approvals, updating procedures and documentation, training affected personnel, and verifying the change during and after implementation. The goal is to ensure that alterations to equipment, materials, operating conditions, or control strategies don’t introduce new risks or undermine safety and reliability. Other terms like change control or change management are used in different contexts and don’t inherently require the comprehensive hazard-focused review and authorization that MOC mandates.
