In the color-coded hydrant system, which color is used for the highest flow category (1500 gpm)?

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

Answer: (B)

Color coding hydrants lets crews gauge available water flow at a glance. Each hydrant is painted a color that maps to a flow range. For the highest category, 1500 gpm, the color used is light blue. So, when you see light blue, you’re looking at a hydrant capable of about 1500 gpm—the top tier in this scheme. Other colors indicate lower flow ranges, so red, orange, or green would not represent the top capacity. (Remember, exact color mappings can vary by jurisdiction, so follow local guidelines.)
