Possible exposures to crystalline silica, lead (7439921), and total particulates were reviewed at Champion International (SIC-2621), Frenchtown, Montana, in response to a request by the Hellgate Local 885 of the United Paperworkers International Union. The hog fuel and waste fuel boilers were the areas of specific concern at this paper mill. Breathing zone samples collected for nine locations were found to be below the evaluation criteria for crystalline silica and total particulate contents. Respirable silica was present at 0.02mg/m3 at its highest concentration. Results of the bulk analyses showed that the workers were exposed to material containing only 3.1 percent quartz (14808607) and less than 0.75 percent cristobalite (1446461), suggesting no hazard from crystalline silica. Respirable particulate concentrations ranged from 0.2 to 11.0, with a average concentration of 4.12mg/m3. Lead and chromium (7440473) were below the detection limit. A bulk sample of gasket material was 50 to 60 percent chrysotile (12001295) asbestos. The author concludes that a potential health hazard existed from exposure to total dust in the boiler area, and from installation of asbestos gasket material. Workers involved in handling the gasket material should be advised that it is made of asbestos and to take the required safety precautions. The asbestos gasket material should be replaced by some less hazardous material.
