3M™ Scotch-Brite™ Products, 7448, 7448B, 7468
__________________________________________________________________________________________ Page: 6 of 10 - This document covers only the 3M product. For complete assessment, when determining the degree of hazard, the material being abraded must also be considered. This product contains quartz silica. Quartz silica is a form of crystalline silica. Occupational exposure to inhaled crystalline silica has been associated with silicosis and lung cancer. No exposure to crystalline silica is expected during the normal handling and use of this product. Crystalline silica was not detected when air sampling was conducted during simulated use of similar products containing crystalline silica. Therefore, the health effects associated with crystalline silica are not expected during normal use of this product. Toxicological Data If a component is disclosed in section 3 but does not appear in a table below, either no data are available for that endpoint or the data are not sufficient for classification.
