Title Risk of pneumoconiosis in 2 silicon manufacturing plants
Original title Risques de pneumoconiose dans 2 usines de fabrication de silicium [in French]
Bibliographic information 1984, Vol.45, No.4, p.292-296. Illus.
Abstract Dust analysis was done in 2 silicon-manufacturing plants. In one of the plants, among 14 workers posted at the silicon-manufacturing furnaces and having radiographic anomalies, 6 were subjected to an examination involving clinical, respiratory function, anatomopathological and mineralogic tests. Droplets composed of amorphous silica and oxygen were observed at the alveolar macrophage level. It is suggested that amorphous silica might be responsible for the development of a particular type of pneumoconiosis. The need is shown for dust monitoring and medical surveillance of people working with silicon furnaces. Discussion of control measures and of compensation of this kind of pneumoconiosis.
