Solidification 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 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 کاملhazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures
شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Solidification/Stabilization of Lead Contaminated Soil Using Magnesia Phosphate cement and Ordinary Portland cement
Background and objectives: Solidification/stabilization is an effective technique for reducing the leachability of contaminants in soils. Magnesia phosphate cement and ordinary Portland cement can be used to remediate soils contaminated. In this study, the performance of the solidified/stabilized soil was compared for mixtures composed of magnesia phosphate and ordinary Portland cement. Materia...
