Which color code is used for hydrants with flow rates of 1,500 gpm or more?

• A. Light blue
• B. Yellow
• C. Purple
• D. Brown

Answer: (A)

Visual hydrant color coding communicates the approximate water supply available from a hydrant, allowing firefighters to gauge capacity at a glance and plan hose lines and water supply strategies accordingly. In this common scheme, a hydrant capable of delivering 1,500 gallons per minute or more is marked with light blue, signaling high-flow capability for large or rapid-fire attacks. This quick cue helps decide whether a single hydrant suffices or if additional sources or multiple hydrants will be needed. Other colors represent lower flow ranges, but the key point is that light blue indicates 1,500 gpm or more. Remember that local jurisdictions may use slightly different color mappings, so always refer to local standards.
