NFPA colour code for hydrant flowing 5678 L/min (1500 gpm) or more?

NFPA colour code for hydrant flowing 5678 L/min (1500 gpm) or more?

• A. Light blue
• B. Green
• C. Orange
• D. White

Answer: (A)

Understanding hydrant color coding helps you gauge water supply at a glance. The color that indicates 1,500 gpm (about 5,678 L/min) or more is light blue. Since 5,678 L/min equals 1,500 gpm, this hydrant would be colored light blue. The other colors map to lower flow ranges (orange for roughly 500–999 gpm, green for about 1,000–1,499 gpm), and white is not part of the standard high-flow category. So the hydrant flowing 5,678 L/min or more is correctly color-coded light blue.
