Which hydrants have a GPM range of 1000-1500?

• A. Blue hydrants 1500+
• B. Green hydrants 1000-1500
• C. Orange hydrants 500-999
• D. Red hydrants 0-500

Answer: (B)

Hydrants are color-coded to show approximate gallons per minute of available water. A GPM range of 1000-1500 is represented by green hydrants, so green hydrants match that range. Blue hydrants indicate 1500+ GPM, orange hydrants indicate 500-999 GPM, and red hydrants indicate 0-500 GPM. This color guidance helps firefighters quickly select a hydrant with enough supply for the attack and plan hose lines and pump pressures accordingly.
