Which data element is not required to be recorded at the system riser for an inspection of a pre-action system?

• A. Date of last trip test
• B. Inspectors name
• C. Internal condition of the valve
• D. Tripping time

Answer: (C)

Main concept: data documented at the system riser during a pre-action system inspection should capture observable, test-based evidence of the system’s readiness and accountability.

The internal condition of the valve is not something you can determine just by looking at the riser or during a basic riser inspection. Assessing valve internals requires disassembly or internal inspection and is typically handled in separate maintenance or service records, not as part of the riser data collection. In contrast, recording the date of the last trip test and the tripping time provides verifiable, time-stamped evidence that the system has been tested and responds within expected parameters, and noting the inspector’s name establishes who performed the check. These items are routinely captured at the riser to document compliance and accountability, while the valve’s internal condition belongs to a broader maintenance program rather than the riser inspection record.
