The hydrant colored Light Blue indicates which flow range?

• A. Red
• B. Green
• C. Light Blue
• D. Orange

Answer: (C)

Hydrant color coding communicates available water flow, helping firefighters estimate the water supply quickly. A hydrant colored light blue is read as a high-flow source, typically rated at 1500 gallons per minute (gpm) or more. This makes it especially valuable for large or fast-moving fires where a strong water supply is needed. The other colors indicate progressively lower flow ranges, with red representing the smallest, orange a bit higher, and green a moderate-to-high range—not as large as light blue. So the light blue designation points to one of the highest flow hydrants available.
