Kaj Ahlman and Eero Siltanen, Exposure of Insulation Workers to Asbestos Dust (1971)

A five-page article by Kaj Ahlman and Eero Siltanen of Finland's Institute of Occupational Health, from the Helsinki journal Work-Environment-Health (1971). The register of occupational diseases listed 56 cases of asbestosis among Finnish insulation workers from 1938 to 1968, and the authors measured dust where insulation was made, installed in buildings, and removed in shipyards. Dust levels exceeded the recommended limits "many times," and the insulators, with one exception, did not wear masks because they found it impossible in cramped spaces.

What it shows

The authors concluded that the many recent cases of asbestosis among insulators in construction and shipbuilding showed "that previously there was little knowledge about the health risks connected with this work or that such knowledge was simply ignored," and that many workers were still exposed to dangerous concentrations. The copy ends with the journal's guide for authors.
