A NIGHT MARE SCENARIO
You and your engine crew are responding to a structural fire in the middle of a dark and stormy night. As you are approaching the 1700 square foot, single story home, you can tell that the house is fully engulfed in flames and you call for manpower help from a nearby department. The high winds from storm have whipped the flames into a frenzy, driving the rain sideways reducing your visibility and making it a struggle to find a fire hydrant. Finally, you find one right across the street, and pull a hose to begin to combat the fire. Just then, mutual aid arrives, and you instruct them to pull a hose on another hydrant. That’s when you realize that you aren’t getting the water flow you need from this hydrant, putting your fellow firefighters at risk. But before you can radio to warn them, the neighboring department clogs up the radio channels trying to find out where the closest hydrant is.
ALL HYDRANTS AREN’T CREATED EQUAL
Although you would think that all fire hydrants are created equal, there are many variables that effect the performance of a hydrant, including age of the hydrant as well as the age and size of water main feeding the hydrant. Therefore, NFPA (National Fire Protection Agency) standard is to color code hydrants by gallons per minute of water flow.
The NFPA 291 markings are:
Blue = 1500 GPM or more
Green = 1000 – 1499 GPM
Orange = 500 – 999 GPM
Red = below 500 GPM
Firefighters routinely calculate water flow calculus to determine how much water flow is necessary to effectively extinguish a fire. Although there are other variables to consider, the fully engulfed, 1700 square feet, single story, home in our earlier example will require approximately 566 gallons per minute to extinguish.

THE SAFE SCENARIO
You and your engine team are responding to a structural fire in the middle of a dark and stormy night. As you are approaching the 1700 square foot, single story home, you can tell that the house is fully engulfed in flames and you call for manpower help from a nearby department. The high winds from storm have whipped the flames into a frenzy, driving the rain sideways reducing your visibility. Thankfully, On Scene Specialty Service’s hydrant markers allow you to easily spot the hydrant coming down the street. Unfortunately, though they are all marked as RED and you know you need to find at least an ORANGE marker to fight this fire. Looking down a side street, you spot a BLUE marker and turn off to lay down your hose. As you are doing so, mutual aid arrives easily finds another BLUE marker. In a minimal amount of time, you and your team have water on the fire and everyone comes home safely.
