What color top denotes a hydrant class that can support a flow rate of 500 - 999 gpm?

In the context of hydrant color coding, the color orange is specifically designated to denote hydrants that are capable of supporting a flow rate between 500 and 999 gallons per minute (gpm). This classification is part of a standardized system used to quickly identify the flow capabilities of fire hydrants, which is critical for fire department operations.

The color coding assists firefighters in assessing the water supply available from a hydrant during an emergency situation. An orange top indicates a moderate flow rate, providing them with crucial information for planning firefighting tactics effectively. Hydrants with this flow range are typically adequate for many types of residential firefighting scenarios or smaller commercial structures.

Understanding this color coding system is vital for ensuring that firefighters can quickly gauge the resources available to them upon arrival at an emergency scene. Thus, the orange color top is correctly aligned with the specified flow capacity.
