Determinants of Respirable Crystalline Silica Exposure

The tasks of grinding and cutting stone with a 5″, 9″, and 12″ grinder produced large clouds of dust-laden air too rapidly for it to be captured by the capture arm. Workers regularly worked with large pieces of stone up to 3 m in length, and it was not practical for the worker to regularly reposition the arm as this involved him stopping the task periodically. Capture arms are not recommended for these work tasks
