Which hydrant color represents a flow capability of 1500 gpm or more?

The color that represents a hydrant flow capability of 1500 gallons per minute (gpm) or more is blue. Fire hydrant color coding is a standard practice used to quickly identify the flow rates available from that hydrant. The blue color specifically indicates that the hydrant can deliver a high volume of water, meeting the needs for significant fire suppression efforts.

In contrast, red typically denotes a very low flow capability, which might be around 500 gpm or less, while orange represents an intermediate flow capacity, generally between 500 and 1000 gpm. Green indicates a flow capability from 1000 to 1499 gpm. Thus, when you see a blue hydrant, you can be assured that it is equipped to handle larger firefighting operations, which are essential in managing larger fires effectively.
