| Resumen |
Dust measurements were made in 51 iron, 9 steel, and 8 non-ferrous foundries, employing 4,316 foundrymen. The sampling lasted at least 2 entire shifts or work days continuously during various operation in each foundry, the samples being collected at fixed sites or in the breathing zones of the workers. A total of 3,188 samples were collected in the foundries and 6,505 determinations were made in the laboratory. The highest dust exposures were found during furnace, cupola, and pouring ladle repair. During cleaning work, sand mixing, and shake-out operations excessive silica dust concentrations were also measured. The lowest dust concentrations were measured during melting and pouring operations. Moderate dust concentrations were measured during coremaking and moulding operations. The results obtained during the same operations of iron and steel foundries were similar. The distribution of the workers into various exposure categories, the content of respirable dust and quartz, the correlation between respirable dust and total dust, and the correlation between respirable silica and total dust concentrations are discussed. Observations concerning dust suppression and control methods are briefly considered. |
