A temporary change that is working out can be considered closed with no further action.

• A. True
• B. Only if risk is low
• C. Requires formal sign-off
• D. False

Answer: (D)

Temporary changes are not just about whether things are currently working; they change the risk landscape and need to be treated as controlled actions with a formal close‑out. Even if the change appears to function as intended, you should still verify that all safety controls remain effective, document the outcome, and update relevant systems and procedures. A defined end condition or revert plan should be established, and the change should be formally reviewed and signed off by the appropriate authority. Without this formal closure, the temporary modification can linger unnoticed, potentially becoming permanent or introducing hidden hazards. So, the statement is false because proper closure is a controlled, documented step, not an automatic assumption based on current performance.
