Asbestos exposure during routine brake lining manufacture.
Occupational exposure to asbestos fiber and total dust of workers of a major brake lining manufacture plant in a developing country were examined and compared with those in developed countries. Time weighted average of total dust and asbestos fiber concentration in the potential sources of exposure were monitored. All personal air sampling were collected on membrane filters and analyzed by phas...
متن کاملAsbestos bodies in bronchoalveolar lavage fluids of brake lining and asbestos cement workers.
Asbestos body (AB) concentrations in bronchoalveolar lavage samples of 15 brake lining (BL) workers exposed only to chrysotile have been determined and compared with those from 44 asbestos cement (AC) workers extensively exposed to amphiboles. The mean AB concentrations (263 +/- 802 and 842 +/- 2086 AB/ml respectively) for those groups did not differ significantly but were much higher than thos...
متن کاملSolidification and Stabilization of Asbestos Brake Lining Dust Using Polymeric Resins
Two polymeric resins, Polymal and Hetron, were evaluated to solidify/stabilize (S/S) for ultimate disposal brake lining dust containing asbestos. This dust was generated as part of a sequence of processing steps in the manufacture of automobile brake linings. The mean grain size of the lining dust for disposal was 298.2 m m, the range being from 24.9 to 567.3 m m. Based on the Toxicity Characte...
متن کاملAsbestos Presence in a Factory that Produced Asbestos-Containing Products
In 2007, research was carried out to determine the type and amount of asbestos fibers in a Croatian factory with a long history of making asbestos-containing products.Since the 1970s, asbestos fibres have been considered carcinogenic in humans i.e as a known cancer-causing agent. In the environment, asbestos fibres are inactive and naturally resist biodegradation. In time, fibres can only be gr...
متن کاملtotal dust and asbestos concentrations during asbestos-containing materials abatement in korea
this study was performed during the abatement of two asbestos-containing materials (acm):baumlite board (cement flat board) and ceiling textile. the concentrations of total dust for personal sampling were 0.28 and 1.70 mg/m3 during baumlite board and ceiling textile abatements, respectively, when calculated with 8-hr time-weighted average (twa). the geometric mean (gm) asbestos concentrations w...
