What color hydrant indicates 1000-1499 GPM flow?

The correct answer is that a green hydrant indicates a flow capacity of 1000-1499 gallons per minute (GPM). Hydrants are color-coded based on their flow rates to provide firefighters with a quick visual reference regarding the availability and capacity of water supply from that hydrant.

In this system, green is specifically designated to represent hydrants that can deliver moderate to high flow rates, ensuring sufficient water supply for firefighting efforts. This is vital for effective extinguishing of fires, particularly in larger structures or big incidents where higher volumes of water are needed.

Knowing the color codes and their corresponding flow rates allows firefighters to assess hydrants swiftly during emergency responses, facilitating a more efficient attack on fires and improving overall safety for both the responders and the public.
