What color is associated with hydrants rated for 1500 or more gallons per minute (GPM)?

Hydrants that are rated for 1500 gallons per minute or more are associated with the color blue. This color coding is part of the National Fire Protection Association (NFPA) standard for hydrant color coding, which helps to easily identify the flow rate of fire hydrants. A blue hydrant indicates that it can provide an excellent water flow, which is important for firefighting operations.

In contrast, other colors represent different flow rates. For instance, red indicates a low flow rate of less than 500 GPM, green signals a moderate flow rate of 1000 to 1499 GPM, and orange suggests a flow rate of 500 to 999 GPM. Knowing these color designations is crucial for firefighters to quickly assess water supply capabilities when they arrive at a scene.
