What is the NFPA color code for a hydrant flowing less than 500 gpm?

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

Answer: (D)

NFPA hydrant color coding uses color to show how much water a hydrant can supply. When a hydrant is capable of less than 500 gallons per minute, it is painted red. This quick visual cue helps firefighters decide whether that hydrant can be relied on as a primary water source or whether to seek additional sources or use multiple hydrants. Other colors (like orange, green, or light blue) indicate progressively higher flow capabilities, so they would not indicate the low-flow category. Color coding like this comes from NFPA guidelines and is used to speed assessment on scene, though exact practices can vary by department.
