NYC 9/11 Public Portal Document

Decontamination tent was setup outside plenum area between ACS 2 & ACS 3. All fan intakes were sealed, along with protection of fan motors. After shutdown, fans 5 & 6 were left onto provide some ventilation throughout the building, with minimum static pressure.

Crews worked simultaneously on both sides of damper bank and plenum, performing a hand scrubbing of all exposed surfaces. After pigeon grating was removed and disposed of, top and front louvers were cleaned using pressure washer and done again by hand. They also attempted to clean the top row of slope glass at a difficult angle. I made arrangements to have the slope hosed down by engineering upon completion of the work.
