What color is a Class C fire hydrant that flows less than 500 GPM?

A Class C fire hydrant that flows less than 500 gallons per minute (GPM) is color-coded red. This color designation indicates a lower flow capacity, which helps firefighters quickly identify the hydrant’s ability to provide water for firefighting operations. The red color is part of a standardized system used across various jurisdictions to communicate flow capabilities at a glance. Understanding these color codes is crucial for efficient fire response, ensuring that firefighters are aware of the limitations of each hydrant in the field and can make informed decisions regarding water sources during an emergency. The other colors, such as orange, green, and light blue, represent higher flow rates, which are essential for different firefighting scenarios, but they do not apply in this case as the question specifically refers to a Class C hydrant with a flow rate under 500 GPM.
