Diesel engine-driven fire pumps shall be operated ______.

Explanation:
Diesel engine-driven fire pumps are exercised weekly to keep them ready for service. Running the unit on a regular weekly basis ensures the engine starts reliably, the pump develops the correct discharge pressure, and the lubrication, cooling, and fuel systems stay in good working condition. This weekly exercise helps catch issues before an emergency demand, such as hard starts, loss of pressure, or abnormal vibrations. During the test, you start the engine, bring it to operating speed, and run the pump with the discharge valves open long enough to verify proper pressure and that controls, alarms, and gauges respond correctly, while monitoring oil pressure, temperatures, and fuel quality. Frequencies like daily, monthly, or annually aren’t aligned with typical maintenance practice for confirming readiness.
