After Tokyo, the Fire Department City of New York (FDNY) is the second largest in the world. The FDNY operates in their five boroughs Manhattan, the Bronx, Brooklyn, Queens and Staten Island and has 254 stations. At 42 Great Jones Street in downtown Manhattan, engine 33 and ladder 9 are based. This ladder is a tower ladder or hydraulic platform. It is based on a Seagrave chassis, built up by Saulsbury in 1999 who installed the 95ft (29m) Baker Aerialscope boom. The ladder companies in New York are tasked with forcible entry, search and rescue, ventilation and fire fighting from their ladder.
