Except for the 15°' floor and the 12' floor these values are all less than the OSHA lead PEL of50 4g/m'. Before and during the time of air sampling the fire escape doors to these floors were left open all day and all night to cool the floor. It is believed that the lead its these samples blew in through the open fire escape doors and deposited on the filter media of the samples. We believe that the lead levels in these spaces were temporary and that they settled to the floor. The 1S" floor and 120f floor were re- sampled on September 29s', 2001, to more fully characterize the lead in air values.

The respirable dust (breathable) in air samples were collected from areas considered representative of the building. R.espirable dust samples were collected to show particle dust mass and the distribution of particle size. Only one sample was collected from each area to speed up th e building screening process. The respirable dust in air results are presented i:7 the tables below.
