Which hydrant color represents a flow rate of 1,500 gallons per minute and higher?

The color associated with hydrants indicating a flow rate of 1,500 gallons per minute and higher is light blue. This color coding system is designed to provide firefighters with quick visual cues regarding the available water flow from a hydrant during an emergency incident.

Light blue signifies that the hydrant has an exceptionally high flow capacity, meaning it can deliver a substantial amount of water quickly. Such a flow rate is essential for combating larger fires or situations requiring significant water usage, as it enables firefighters to apply sufficient water to suppress flames effectively.

Understanding these color codes allows firefighters to make rapid decisions about which hydrants to utilize upon arrival at the scene of a fire, directly impacting their operational efficiency and effectiveness.
