Multiple Choice

Electric motor-driven fire pumps shall be operated ______.

Explanation:
Regular exercise keeps a fire pump ready to perform when needed. For electric motor–driven fire pumps, the required practice is to operate the pump monthly. This routine checks that the electric motor starts reliably, the automatic starting and control circuits function, the pump reaches operating speed and develops discharge pressure, and that alarms, gauges, and other interlocks are working. It also helps confirm there’s no sticking or priming issues and that the overall system remains healthy without causing unnecessary wear from more frequent runs. Weekly operation is typically reserved for diesel-driven pumps, which have different maintenance needs, while daily operation would add excessive wear for electric motors without providing additional reliability benefits.
