• Use a smaller wheel and use the least aggressive tool that will do the same job whenever possible. Larger wheels and more aggressive wheels (e.g., diamond wheels) result in higher silica exposures. • Reduce the amount of fine grinding required. For example, less dust is created when material is removed by chipping instead of grinding. Use
Construction workers who perform concrete grinding may breathe dust that contains respirable crystalline silica (RCS).
