Foam 5 was purchased in 2006 to store all of the foam that is stored at Station 3 and allow it to be more readily transported in the case of an emergency. The trailer is towed by Engine 5 and supplements the foam and equipment that is carried on it. Inside the trailer are a number of 55 gallon drums combined for a total of 1200 gallons of AFFF or Aqueous Film Forming Foam, large volume foam nozzles and additional supply hose.
