BATTALION 1

Gerald A. Barbara Chief of Fite Prevention Thru: Peter J. Ganci Chief of Operations From; William P. Blaich Battalion Chief Subject; Dangerous Condition at 7 World Trade Center - Update Date; March 14, 1999

The mangers of 7 World Trade Center have installed a 6,000Ga!lon Fuel Oil Tank This tank is installed on steel beams at a height of approximately 15 feet above die floor. That is, a suspended diesel fuel oil tank. The area surrounding the tank has a firewall rating of four hours. The bottom of the tank area is concrete over Q- Decking. The onh access into this area is through a hatch in the floor There is no dike to prevent fuel from pouring out of this hatch in the event of a leak, if it could be opened with the weight of the oil on it. The room that houses this tank enclosure also contains the access doors to two elevator pits and is adjacent to a handicap elevator. Diesel Fuel is transferred from this tank to a pump for movement to the upper floor via a pipe which breeches the elevator bank walls containing elevators 2 i and 22. At this time, the location of the tank vent pipe is unknown. The tank enclosure is also adjacent to the mam lobby

None of the elevator access doors are equipped with a dike to prevent diesel fuel oil from leaking into the pits. In the event of a leak, fuel oil would fill the elevator shaft with fumes that would permeate the entire building. A smoky fuel oil fire would be a disaster! An overfill would severely endanger members attempting to contain it.
