Silica Dust – iQ Power Tools

About Silica Dust. Chemical Formula SiO₂. Silica is Quartz, and is found naturally in almost all rock, sand, soil, and concrete products. Respirable crystalline silica particles penetrate deep into the lungs causing lung disease. OSHA, after decades of scientific studies on respirable crystalline silica, adopted its first PEL in 1971.
