| Abstract |
A study of the conditions prevailing in various investment casting shops using fireclays revealed high dust levels which vary according to the raw materials used, the stage of the process and the type of work. Animal experiments showed that the effect of fireclay dust on the respiratory tract is similar to that of aluminium oxide aerosols formed during electric welding and during the processing of artificial corundum (development of diffuse pneumoconiosis). It is recommended not to exceed an exposure level of 6mg kaolin dust per m3. Measures to be taken to improve the conditions of exposure are: substitution of fireclays or other less fibrogenic substances for quartz sand and quartz powder; mechanisation or automation of processes giving rise to dust spread; enclosure of dusty processes; pneumatic conveying systems. |
