In a water spray fixed system, at which frequency should items in areas inaccessible for safety conditions be inspected?

• A. At scheduled shutdowns
• B. Annually
• C. Not more than every 18 months
• D. Every two years

Answer: (C)

When parts of a water spray fixed system are located in areas you can’t access safely, the inspection cadence is set to a practical maximum interval to balance safety with keeping the system reliable. The standard requires inspecting such items not more than every 18 months. That means you should plan to check these components at least once within an 18-month period, and you may inspect more often if access becomes possible or as other maintenance dictates. This helps catch issues like leaks, corrosion, obstructions, or damaged components before they lead to a failure, without forcing crews to unsafe, frequent access. Choosing a different cadence isn’t as appropriate here. Scheduling inspections only at shutdowns isn’t a fixed cadence and can drift with operations. An annual interval is allowed, but the maximum is 18 months, so extending beyond that would violate the guideline. A two-year interval would exceed the permitted maximum.
