Potential health effects

Inhalation: Dusts of this product may cause irritation of the nose, throat, and respiratory tract. This product contains crystalline silica as a contaminant. Prolonged and repeated inhalation of respirable crystalline silica can cause silicosis, a chronic lung disease characterized by fibrosis and scarring of the lung tissue resulting in a decrease in lung function, breathlessness, wheezing, coughing, and sputum production. Short term overexposures to extremely high concentration of respirable crystalline silica can produce acute silicosis. Acute silicosis is a disease that can rapidly progress within months of initial overexposure and reportedly can cause death within 1 to 2 years. Skin Contact: Dust may produce contact dermatitis Eye Contact: May cause slight irritation (redness, tearing, and blurred vision) as a dust.
