Abstract |
This study of the levels of exposure to flour dust in flour mills across Canada was conducted to verify existing conditions and to decide whether to adopt the proposed Threshold Limit Value (TLV) of 0.5mg/m3 for flour dust with a sensitization notation. As part of the study, a relationship between flour dust concentrations obtained by using IOM samplers and closed-face 37mm cassettes was examined and the literature on the health effects of exposure to flour dust was reviewed. A total of 104 workers from 14 flour mills were sampled over an 8-hour work shift using IOM samplers. The results indicated that 101 employees (97.1%) were exposed to levels exceeding 0.5mg/m3, 66 employees (67.3%) to levels exceeding 5mg/m3, and 44 employees (42.3%) to levels exceeding 10mg/m3. Flour dust measurements were also taken in a highly automated flour mill using state-of-the-art technology. Results suggest that even with the most up-to-date technology and regular cleaning operations in place, the flour milling industry may not be able to reduce the flour dust levels to below the proposed TLV of 0.5mg/m3. |
