Dear Joel K pfermsn,

I have reviewed the December 9, 2001 report an asbestos sampling done by Ed Olmsted, cIv, at 105 Duane street. i concur with Mr. Olmsted'a conclusion tbAt the eamle taken from the air diffuser in the loth floor public hallway .$.ewe levels of asbestos well above the recommended limit of 2.000 structure per square centimeter. I also concur that the finding of 555,000 asbestos structure per square eeatim.ter is a clear %ndication that the ventilation system should be cleaned by a professional duct cleaning compafY using vacuum and cleaning equipment designed fog asbestos dseontu tnation. z would add that the work moat be done by trained and certified asbestos abatement workers who can prevent contamination of other parts of the building while they work. 2 also would add that this single sampLe should be followed up by other samples taken from other locations in the ventilation system.. This sampling must be undertaken immediately because asbestos fibers in ventilation systems are likely to deposit throughout the building. The reading of 740 asbestos structures is high enough per square centimeter on the living room table tophazardous. to cause concern that further deposition could be It levels the elsani~i is delayed until many spartmenti attain pcneritially. requiring abatement, the cost of cleanup will rice a It is also 113e1 that there are already apartments in the building in which the asbestos duct levels are much higgher. These locations are most likely to be those in which the air is supplied by diffusers that are closer to the ventilation system's air intakes and filters. people living in these apartments may be at risk now.
