  • Method for Determining Crystalline Silica in Bulk Samples

    A river sand, comprised predominately of coarse silica, will present less of a respirable dust hazard risk than silica flour, primarily a very fine powder, which would pose a vastly enhanced risk. Although the three above-mentioned products may give a similarly high percentage of crystalline silica in the bulk sample, they pose different crystalline silica inhalation hazard risks.
