Exposure to Fibers in the Manufacture of Fibrous Glass (1969)

This article reported an air-sampling survey of worker exposure to dust and fibers in the fibrous glass industry, carried out by the U.S. Bureau of Occupational Safety and Health. It covered five fibrous glass factories, four making insulation and one making textiles. The survey was done while personnel records were being collected from these plants for a planned study of deaths among past fibrous glass workers. That planned study was to be compared with a Public Health Service study of the asbestos product manufacturing industry, and the survey used the sampling methods developed for the asbestos study. Exposure was measured as gross and respirable dust and as gross and respirable fibers, mainly with membrane filters. In the article's own summary, the authors reported that the surveys indicated workers' exposure to respirable fibers had been negligible. They also reported that present average fiber concentrations in air, and total airborne glass, were low. The available copy is poorly legible and breaks off during the methods. Its dust tables are too damaged to report reliably, and the fiber results and discussion are missing.
