What color hydrant indicates a flow rate over 1500 gpm?

1. Red

2. Yellow

3. Light Blue

4. Green

The correct answer is: Light Blue

The color that indicates a flow rate over 1500 gallons per minute (gpm) is light blue. This color coding is part of a system used to quickly identify fire hydrant flow capabilities, which is essential for firefighters responding to emergencies. Light blue hydrants signify that they can provide a high flow rate, which is crucial in firefighting operations where a robust and steady water supply is needed to combat large fires effectively. The higher the flow rate, the more water is available to extinguish flames, making light blue a clear and effective indicator of hydrants that can support significant water demands. Understanding hydrant color codes can drastically affect how quickly responders can strategize and manage firefighting efforts. Hence, recognizing the respective flow capabilities based on color coding becomes a vital part of fire safety and emergency response planning.
