Silicosis in the 1980's.

D E Banks, K L Morring, B A Boehlecke

    American Industrial Hygiene Association Journal
    |January 1, 1981

    Summary

    Workers in silica flour mills face a high risk of silicosis due to prolonged exposure to free silica dust. Despite regulations, dust levels remain elevated, necessitating urgent prevention efforts.

    Area of Science:

    • Occupational Health
    • Industrial Hygiene
    • Pulmonary Medicine

    Background:

    • Silica flour mills have a history of failing to meet Mine Safety and Health Administration (MSHA) dust exposure standards.
    • Previous investigations indicate a significant risk of silicosis among exposed workers.

    Purpose of the Study:

    • To investigate the health of workers at two silica flour mills.
    • To assess the prevalence of silicosis in relation to workplace silica dust exposure.
    • To review MSHA dust measurements across the silica flour industry.

    Main Methods:

    • Conducted a health investigation of workers at two specific silica flour mills.
    • Reviewed chest radiographic evidence of silicosis in exposed workers.
    • Analyzed MSHA silica dust measurements from 27 U.S. silica flour producers.

    Main Results:

    • 37% of 61 workers with silica dust exposure showed radiographic evidence of silicosis.
    • 89% of workers in 27 silica flour mills were employed in areas exceeding 25% of dust samples above the MSHA standard.
    • 53% of all reviewed dust samples exceeded the MSHA standard, with no significant decline from 1974-1979.

    Conclusions:

    • The risk of silicosis is exceptionally high for workers in the silica flour industry.
    • Effective prevention requires collaborative efforts from government agencies, management, and workers.
    • Continued exposure to unsafe silica dust levels poses a significant occupational hazard.
