| Abstract |
The fibre exposure associated with the use of refractory ceramic fibres (RCF) in smelters and foundries was investigated. Participating employees and contractors were classified into three exposure categories, depending on their distance from the fibre source. The highest concentration of airborne ceramic fibres occurred in category 1, whose members actually handled RCF. The median fibre concentrations in this category varied between 0.26 and 12 fibres/mL for different plants. During certain extreme operations concentrations up to 210f/mL were measured. For exposure categories 2 (work on or near equipment containing RCF) and 3 (work in shops where such equipment was located), the corresponding plant median values were 0.03-0.24f/mL. A dose estimation shows that certain occupational groups may be exposed to an environmental risk. Different methods for controlling fibre emission are discussed. |
