Abstract |
The report gives results of a study to provide information, from both the literature and user contact, on the control of asbestos emissions from enclosed sources. It assesses the state-of-the-art in asbestos emission control in terms of the devices or methods used and their efficiency. In addition, it gives results of a preliminary study to actually measure the effectiveness of baghouse control devices in controlling emissions from five asbestos plants. Baghouses are the predominant control device used in the asbestos industry. Cotton bags are used most frequently. Automatic shaking is used in most baghouses. Published data on the removal efficiencies of the control devices was either non-existent, or quoted in general terms. Five baghouses were tested fro removal efficiency in terms of mass and fiber number. Using computer modeling, it was found that, even considering one source, asbestos concentrations of 500 f/cu meter can be anticipated 5 km from the source. The exposure level at which asbestos in ambient air becomes a health hazard is not known. |
