Silica laden material can break down into particles small enough to inhale when workers chip, cut, drill, or grind it. This is exactly what happens during frac sand mining." This problem also extends to workers on a frac site where the sand is being used as a proppant when mixed with water and frac chemicals for injection into a well bore.

Silicon concentrates in no particular organ of the body but is found mainly in in connective tissues and skin. Silicon is nontoxic as the element and in all its natural forms, nameli silica and silicates, which are the most abundant. Elemental silicon is an inert material, which appears to lack the property of causing fibrosis in lung tissue.

Silica overexposure is a potential hazard whenever resource extraction such as mining (underground or openpit) or ore processing involves silicabearing materials. The geology of uraniumbearing ore deposits is such that typically concomitant silica exposure cannot be avoided during mining and processing uranium.

What is respirable crystalline silica (RCS)? Dust can be made up of visible (larger) and microscopic (smaller) particles. Particulate matter is defined as airborne material (solid or liquid) that is smaller than 100 microns (millionths of a meter) in size. For comparison, human hair is typically between 70 to 100 microns in diameter.
