Which of the following indicates a flow rate of 1,000-1499 gallons per minute?

The color-coding system for hydrants helps fire departments quickly determine the flow rate of water available from each hydrant. A green hydrant specifically indicates a flow rate of 1,000 to 1,499 gallons per minute. This range is significant because it offers a sufficient supply of water for most firefighting operations, allowing firefighters to effectively combat fires in residential and some commercial structures. Understanding these color codes enhances the readiness and efficiency of fire response, as firefighters can prioritize which hydrants to use based on their flow rates.
