What color indicates a Class AA fire hydrant that flows 1500+ GPM?

A light blue color indicates a Class AA fire hydrant that flows 1500 gallons per minute (GPM) or more. This color coding system is utilized by fire departments to easily identify the hydrant flow rates during emergency situations. It allows firefighters to quickly gauge the available water supply at a particular hydrant, which is crucial for effective fire suppression efforts.

The classification of hydrants based on their flow rates helps ensure that firefighters can make informed decisions about which hydrants to utilize when responding to a fire. For a Class AA hydrant specifically, the light blue color signifies that it can deliver a high flow rate, thus providing ample water for firefighting activities.
