What color represents a hydrant with a flow rate of 500 gallons per minute?

A hydrant with a flow rate of 500 gallons per minute is represented by the color red. This designation is part of a color-coded system established by the National Fire Protection Association (NFPA) to indicate the water flow capacity of fire hydrants.

In this system, red generally indicates a low flow rate, specifically for hydrants that can deliver between 0 and 500 gallons per minute. This is crucial for firefighters who need to quickly assess whether a particular hydrant can meet their water supply needs during an emergency response. Understanding this color coding helps ensure that firefighters can efficiently identify viable sources of water when battling fires, significantly influencing their tactics and strategies in firefighting scenarios.
