What does a red hydrant signify?

A red hydrant signifies that the water flow potential from that hydrant is less than 500 gallons per minute (gpm). This color coding is part of a standardized system used by fire departments to quickly assess the flow capabilities of hydrants during emergency situations. The red color indicates that these hydrants have a limited capacity, which is important for firefighters to know when determining water supply needs for firefighting efforts.

This information allows responders to make informed decisions on whether they can rely on that particular hydrant for their operations or if they need to seek alternative sources. The other color designations represent higher flow rates, indicating that those hydrants can deliver more water, which is crucial for fighting larger or more intense fires. Understanding these color codes helps ensure efficient and effective fire suppression tactics.
