Practice questions
Preparation prompts derived from this entry, not an official inspector interview script.
1Why is an “open” light alone insufficient after a reported valve fault?
The source identifies incorrect position indications caused by instrument, panel or slow-valve faults. Verify actual operation and timing against maker guidance.
2Does RISQ give one universal opening time for every valve?
No. It calls for regular timing checks using the manufacturer’s guidance.
Where a finding may arise
Missing evidence, defects or operation inconsistent with the arrangements described above may prevent a satisfactory answer. These are preparation concerns derived from the question, not reported past observations.
Past observations for practice
