SECTION 2: Hazards identification

OSHA Carcinogenicity: NTP- Yes IARC Monographs- Yes OSHA Regulated- No This product itself is not regulated but it contains small amount of naturally occurring crystalline silica. IARC Monographs on the Evaluation of the Carcinogenic Risk of Chemical to humans (volume 42, 1987) concludes that there is sufficient evidence for the carcinogenicity of crystalline silica to experimental ani- mals, and that there is limited evidence of the carcinogenicity of crystalline silica to humans. IARC Class 2A. Irritants: Eye Contact: Dust may irritate the eyes from mechanical abrasion causing watering and redness. Skin Contact: May cause irritation of the skin from friction but cannot be absorbed through intact skin. Inhalation: Acute effects: Dust may cause irritation of the nose, throat, and airways, resulting in coughing and sneezing. Certain susceptible individuals may experience wheezing (spasms of the bronchial airways) on inhaling dust.

Potential chronic health

Repeated and prolonged overexposures to dust containing crystalline silica causes sili- cosis (scarring of the lung) and increases the risk of bronchitis, tuberculosis, lung cancer, renal disease, and scleroderma (a disease affecting the connective tissue of the skin, joints, blood vessels, and internal organs). Studies have shown cigarette smoking increases the risk of silicosis, bronchitis, and lung can- cer in persons also exposed to crystalline silica. Ingestion: Unlikely under normal conditions of use, but swallowing this product may result in irritation or damage to the mouth and gastrointestinal tract due to mechanical abrasion.
