Air S S,p7 g N isance Dust 4 Silic PSI collected 2 representative air samples from each odd numbered floor of the north and south buildings. Samples'were collected from common corridors, escalators, the Gymnasium and Theater 3. A total of 16 samples were collected and analyzed by NIOSH Method 7500 to determine ambient or background airborne nuisance dust and respirable silica concentrations. Nuisance dust concentrations ranged from 0.0578 mg/m3 to 0.6178 mg/m' which are below the OSHA limit of 5 mg/m' and the ACGIH limit of 3 mg/m'. Respirable silica was detected In two (2) samples and not detected in fourteen (14) samples. Concentrations in the two samples detected were 0.0213 mg/n? and 0.0276 mg/m3, which are below the NIOSH limit of 0,05 mg/rn3 and the ACGIH limit of 0.1 mghns.
Refer to the attaobcd laboratory analysis conducted by BMSL Laboratories for the analytical results.
Airborne Metals. Air samples were collected on December 15th from each floor in the North Building and the South Building and from eight (8) Trailers. A total of 23 samples were collected and analyzed by NIOSH Method 7300 to determine ambient or background levels of airborne lead, chromium, arsenic and iron concentrations. All samples indicated levels below the NIOSH or ACGH limits established for airborne concentrations of these metals.
Refer to the attached laboratory analysis conducted by American Analytical Laboratories for the analytical results.
Volatile9rganic Ca _undo Measurement of total VOC's is used to determine general quality of air associated with the level of volatile organic compounds. Samples for volatile organic compounds were collected with a MINIRAB 2000, direct reading photoionization detector. Samples were collected within the North and South Buildings and the Trailers, as well as outdoors. The Indoor Air Quality Association (Standard IAQA #95-1) recommendal levels be maintained at or below 3.0 ppm for acceptable Indoor air quality. The data indicated that total VOC's were not detected within the areas sampled. Please refer to Table 3 for measured results,
