What color coding indicates that a fire hydrant provides less than 500 GPM?

The color coding for fire hydrants is a standardized system that helps fire departments quickly determine the water flow capabilities of hydrants, which is critical for firefighting efforts. In this system, a red color indicates that a fire hydrant provides less than 500 gallons per minute (GPM). This low flow rate could be insufficient for many firefighting operations, particularly in situations involving large fires or when a significant volume of water is needed rapidly.

Hydrants painted red signal to firefighters that they should be cautious and may need to consider alternative sources of water or additional resources in firefighting scenarios. Understanding this color code can significantly impact the strategies and decisions made during emergency responses, emphasizing the importance of knowing which hydrants are capable of providing adequate water supply.

In contrast, other colors like light blue, green, and orange denote higher flow rates, with light blue representing flow rates greater than 1500 GPM, green for 1000-1499 GPM, and orange for 500-999 GPM. Thus, knowing that red indicates a flow rate below 500 GPM is essential for fire safety and efficient emergency response planning.
