Additional Information:
This product, when used under reasonable conditions and in accordance with the 3M directions for use, should not present a
health hazard. However, use or processing of the product in a manner not in accordance with the product's directions for use
may affect the performance of the product and may present potential health and safety hazards.
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 titanium dioxide and quartz (crystalline) silica. Cancer of the lungs has been associated with inhalation
of high levels of titanium dioxide in animal studies, and occupational exposure to inhaled quartz silica has been associated
with silicosis and lung cancer. No exposure to titanium dioxide or quartz silica is expected during the normal handling and
use of this product. Titanium dioxide and quartz silica were not detected when air sampling was conducted during simulated
use of similar products containing these substances. Therefore, the health effects associated with titanium dioxide and quartz
(crystalline) silica are not expected during the normal use of this product.
