| Abstract |
High Efficiency Particulate Air (HEPA) filtration systems serve as the principal engineering control to remove asbestos particulate from airstreams at abatement projects. However, little quantitative information is available on the integrity of these air filtration systems in preventing asbestos fiber release into outdoor air or adjacent building areas, potentially exposing occupants. A study is in progress to assess the performance of HEPA filtration systems in use at asbestos abatement projects to determine each systems operating particle-removal efficiency, percent concentration, and decontamination factor. The asbestos fiber concentration in the inlet and discharge air of each filtration system will be determined by isokinetic air sampling. Each isokinetic air sample collected will be analyzed using transmission electron microscopy. In addition, in-place aerosol performance testing will be conducted according to procedures outlined in ANSI/ASME N510-1980. The test method utilizes a polydispersed dioctyl phthalate aerosol (generated by Laskin nozzles) and a photometric light-scattering mass-concentration detector as the measuring device. |
