| Abstract |
Surveys were used to assess both the degree of health hazard present and the effectiveness of existing control systems for airborne contaminants in 9 ferrous foundries ranging from small, with limited mechanization to large and highly automated. Substitution and ventilation systems were used in attempts to control silica. The foundry processes evaluated were sand preparation, shakeout, dry sand transport and sand moulding. Exposure was evaluated by personal and area samples. Worker exposure was excessively high in the sand preparation, moulding and shakeout areas, and results indicated that most control systems were inadequate. More effective control methods are recommended, e.g. fully enclosed and exhausted mullers, well designed exhaust systems on shakeouts, local exhaust ventilation on transfer points of sand conveying systems. |
