FDNY Fort Pitt goes on a full house run

We are at quarters of FDNY Engine 15, Tower Ladder 18, and Battalion 4, better known as Fort Pitt, at the corner of Pitt Street and Delancey Street, where we see the entire house go on a run 2nd due for an odor of gas. I am not sure why the rigs used their lights and sirens for a 2nd due response, but it might have been modified as they turned out. Engine 15 is a 2010 Seagrave Marauder II, Tower Ladder 18 is a 2012 Seagrave with a 75 foot Aerialscope, and Battalion 4 is a 2009 GMC 2500. Enjoy the full house response, replete with siren and horn. If you have any questions about the video, feel free to message me. Comments are welcome. The video was taken on April 9th, 2015.
