Tanks not equipped with supervised water level alarms connected to a constantly attended location shall be inspected:

• A. Monthly
• B. Biannually
• C. Annually
• D. Quarterly

Answer: (D)

When there is no supervised water level alarm tied to a constantly attended location, you rely on manual checks to verify the storage tank’s water level and condition. The chosen frequency—quarterly—gives you a practical interval to catch changes in level, leaks, sediment, or damage without overburdening maintenance teams. During the inspection, you verify that the water level is at the required level for firefighting use, look for signs of leakage or deterioration, check vents and access, ensure valves are in proper position, and document the reading and date. If a low level or any issue is found, you take the appropriate corrective action, such as refilling or repairing leaks. More frequent checks would be unnecessarily labor-intensive without an alarm, while less frequent checks could allow problems to go unnoticed.
