If a hydrant is colored red, what range best reflects its available flow?

• A. 500-999 gpm
• B. Less than 500 gpm
• C. 1000-1499 gpm
• D. 1500+ gpm

Answer: (B)

Hydrant color coding gives firefighters a quick read on how much water a hydrant can supply, helping set tactics at a glance. A red hydrant signals a lower water supply, indicating available flow is below 500 gallons per minute. That quick cue matters because it guides how you approach the scene: you’ll plan for a smaller initial attack, consider laying larger or additional hose to reach other water sources, and coordinate closely with the pump operator to ensure the engine can deliver enough water without being bottlenecked. Remember, color is a rapid, practical indicator, not an exact measurement—the actual flow should be verified when possible, but red clearly denotes a low-flow category.
