What About the Blue Nozzle? - Brooklyn, New York

Brooklyn, New York

A quick post for today. I took this photo on a scouting trip with my son for his New York Film Academy short film. I had to chuckle when I saw these brightly covered nozzles on a building in Brooklyn. There were hard to miss placards for the green and pink nozzles and I wondered what the blue nozzle was for and why it didn't have a placard.
