It was in this operation, working as a die repairman, that the claimant waj employed from 1951 until 1970 at the Brookperk plant. This work involves a considerable amount of grinding with rether email air driven grinding wheels. The writer eede a duet count in the breathing sons o.f a workman performing a die grinding operation during hio reoent visit to the Chevrolet plant. This eount showed less than one million particles per oubic foot of air which is quite low. It should also be remembered that wheels employed in this work do not contain silica. Little Is known, about the long defunct John Harsch foundry. It apparently was t notv-ferrous sand operation with a hundred or more employees. Cotuts node here on the foundry floor in 1942 and 1944 showed respectively 1.9 and 6*0 million particles per cubic foot cf air. 1 We here no dust counts from ths Alcoa Sand foundry during the claimant's employment there (1929*1937) battues this period predated the time when dust counts ware initiated by the division. However, there are some 1940 and 1941 counts recorded at the Alcoa foundry that are probably typical of ths claimant's 1929-1937 employment at this foundry.
