Dear Joes3. Rupfermari, I have reviewed the December 9, 2003. report an aebeatee eanpling doe by Ed Olmsted, cm, at YOanuee street I aancur with. Mr. 01mate4's conclusion that the eau le taker. from the air diffuser in the 10th f1per public hallway show levels Of asbestos well above the recomten4e8 limit of 1000 structure per square centimeter. . 1, also*concur that tha''fia din ..' *of 'Ss6, 000 'asbestos structure per square centimeter is a clear Indication that the ventilation system should be cleaned by a professional duct cleaning caenpany using vacuum' and cleaning a ipmment designed for aabestoe decontamination. I would add that the work nist be done by trained and certified asbestos abatement worker' who can prevent conta~ain&t.aon of other parts of the building while they work. 3' also would add that this single øntpl bould be followed up by other eernplea taken from other 1ouationo in the ventilation system. This sawpling must be un4ertaksn immediately becanee asbestos fibers in* ventilation systems are likely to deposit throughout the building. The reacting of 740 aebeetos strvotures per r furtherliving rootu table Cop is high ntineter on the b to cumeconcern that depos deposition .could be haea.rdua- If the cleaning is delayed until waxy apartments attain levels requiring abatement, the cost of cleanup will rise exponex~tially- it as also likel y that there are already apartments in the building in which the asbestos duet levels are much h gher. These loe8tione ere most likely to be those in which the air is supplied by diffusers that are cloeer Co the ventilation systata's air intakes and filters6 i?eople living in these apartments may be at risk now.
