Popis: A medical and environmental evaluation of maintenance-of-way railroad employees has been conducted. Information was gained from chest radiography, spirometry, respiratory symptoms, and employment and personal habit histories. Environmental monitoring consisting of personal air samples was conducted to assess employee exposure to respirable crystalline silica and to develop exposure control strategies. Radiographic evaluation revealed no cases of silicosis or other occupationally induced lung diseases among 501 workers examined. In addition, pulmonary function deficits related to surrogates of silica exposure were absent. However, an expected and ordinary number of nonoccupational conditions and minor impairments were identified. While most environmental monitoring results were within acceptable limits, some samples for specific equipment operators indicated respirable silica exposures exceeding the American Conference of Governmental Industrial Hygienists guideline of 100 μg/m3 of air.
