What color is a Class B fire hydrant that flows between 500-999 GPM?

A Class B fire hydrant is designated by its ability to flow between 500 and 999 gallons per minute (GPM). This flow rate is critical in understanding the hydrant's capability to provide adequate water supply during a fire emergency. According to the color-coding system used in many jurisdictions, an orange color indicates that a hydrant falls within the Class B category, designating it as a reliable source for moderate amounts of water flow. This system allows firefighters to quickly assess the capabilities of hydrants as they arrive on the scene.

The knowledge of hydrant flow rates and their corresponding colors enhances the efficiency of firefighting efforts, as firefighters can make informed decisions about water sources in a timely manner during emergencies.
