Purpose of Inspection:
The primary goal of the inspection is straightforward: to make sure the fire pump assembly is ready to go when needed and that it hasn’t suffered any physical damage that could impede its functionality. By conducting these regular checks, we ensure that our fire pumps are reliable guardians in times of emergency.
Weekly Checklist for Fire Pump Inspections:
Pump House Conditions:
- Check that the pump room with diesel engine–driven pumps and engine heaters maintains a cozy temperature of at least 40°F (4°C).
- Ensure that the pump room with diesel engine–driven pumps without engine heaters stays comfortably warm at no less than 70°F (21°C).
- Confirm that ventilating louvers are free to operate to maintain proper airflow.
Pump System Conditions:
- Check that the pump suction, discharge, and bypass valves are fully open.
- Inspect piping to guarantee there are no leaks that could compromise the system.
- Confirm that pressure gauge readings are within the acceptable range
- Verify the water level in the suction reservoir
- Confirm that wet pit suction screens are unobstructed and in place.
- Check that waterflow test valves are in the closed position when not in use.
Electrical System Conditions:
- Verify that the controller pilot light (indicating power on) is illuminated.
- Check that the transfer switch normal pilot light is also on.
- Confirm that the isolating switch is closed for the emergency power source.
- Ensure that the reverse phase alarm pilot light is off, or the normal phase rotation pilot light is on.
- Check that the oil level in the vertical motor sight glass is within an acceptable range.
- Confirm that power is provided to the pressure maintenance (jockey) pump.
Diesel Engine System Conditions:
- Ensure the fuel tank is at least two-thirds full.
- Check that the controller switch is in auto position.
- Confirm batteries’ voltage and charging are in the acceptable range.
- Check the status of batteries’ pilot lights.
- Ensure all alarm lights are off.
- Check the engine running time.
- Verify the oil level in the right-angle gear drive.
- Confirm the crankcase oil level is acceptable.
- Check cooling water and electrolyte levels.
- Ensure battery terminals are corrosion-free.
- Confirm the water-jacket heater is working.
Steam System Conditions:
- For systems utilizing steam, verify that the steam pressure gauge reading falls within an acceptable range.
Regular fire pump inspections might seem like a technical task, but they are essential for ensuring the safety of occupants in a building or workers in an industrial setting. By following a simple weekly checklist, we can make sure our fire pumps are ready to respond in case of an emergency, providing peace of mind and enhancing overall safety. Remember, a little routine maintenance goes a long way in keeping our fire safety systems reliable and effective.
