According to NFPA 291 standards, what does a color-coded orange fire hydrant indicate?

A color-coded orange fire hydrant indicates that the hydrant has a flow rate between 500 and 999 gallons per minute (gpm). This color-coding system, established by the National Fire Protection Association (NFPA) standards, is a useful method for firefighters to quickly assess the capacity of a hydrant during an emergency response. The specific use of orange for this flow range helps ensure that firefighters are aware of the capability of the hydrant when planning water supply strategies for firefighting operations. Recognizing these color codes can be crucial in effectively managing firefighting resources on scene, ensuring that sufficient water is available to combat a fire.
