| Resumen |
Results of monitoring carried out between 1970 and 1976 to determine beryllium concentrations in fumes given off during the following operations: casting from electric crucible furnaces, adding magnesium, pouring the alloy into a holding furnace, modifying the alloy, and manual casting by ladle. According to calculations made, the mean Be concentration was 0.00000064mg/m3 and did not exceed the Soviet TLV. However, it is considered advisable to avoid pouring the alloy from the melting furnace to the holding furnaces, to melt the constituent metals in closed furnaces, to seal hermetically the hoods over the holding furnaces, and to instal local exhaust ventilation for chill casting processes. |
