Tank heating systems installed on tanks equipped with a supervised low water temperature alarm connected to a constantly attended location shall be inspected how often?

• A. Daily
• B. Weekly
• C. Monthly
• D. Quarterly

Answer: (B)

Regular inspection frequency for supervised alarms that signal to a constantly attended location is weekly. The supervised low water temperature alarm is a critical safety feature for a tank heating system because it needs to reliably alert personnel if water temperature falls to a fault condition. Weekly checks verify that the power supply is present, wiring and interconnections are intact, the alarm and annunciation function correctly, and the signal is reliably received at the attended location. This cadence helps catch faults early without being unnecessarily burdensome, whereas daily would be excessive and monthly or quarterly could allow a fault to go unnoticed for too long in a system where timely notification is essential.
