Statistical evaluation of airborne asbestos measured before, during, and after abatement
Technical Report

OSTI ID:5410770
A statistical evaluation was made of airborne asbestos concentrations measured before, during, and after removal of asbestos-containing fireproofing at three university buildings. Of the three sites studied, all passed the AHERA z-test when the work-area asbestos levels were compared to perimeter levels (outside the abatement area but inside the building). Two sites also passed the z-test when work area and outdoor air levels were compared. At one site, contamination of the perimeter area occurred at some point during the abatement project. Had this area been used in the z-test clearance comparison, a contaminated site would have been falsely released.
