A medical and Industrial hygiene survey was conducted in a facility manufacturing amosite asbestos pipe insulation. In seven of 16 workers with 10 or more years' duration of employment asbestosis was diagnosed on the basis of the presence of three or more of five criteria: (1) significant dyspnea, (2) finger clubbing, (3) persistent rales, (4) restrictive pulmonary function, and (5) small roentgenographic opacities. Workers formerly employed at a predecessor plant manufacturing these amosite insulation products have experienced asbestosis, mesotheliomas, and an increased lung cancer risk. The manufacture and use of amosite asbestos pipe insulation products are hazardous.
