SECTION 2: Hazards identification

EFFECTS OF SINGLE OVEREXPOSURE: SWALLOWING: Slightly toxic. Swallowing large volumes may cause irritation of the mouth and throat, esophagus and stomach, with nausea, abdominal and chest pain, vomiting, diarrhea, dizziness, faintness, weakness, drowsiness and collapse. Aspiration into the lungs may occur during ingestion or vomiting, resulting in lung injury. SKIN ABSORPTION: Prolonged or widespread skin contact may result in absorption of potentially harmful amounts of material. INHALATION: Vapor is irritating, experienced as nasal discomfort and discharge with chest pain and coughing. Dizziness and drowsiness may occur. Eye irritation may occur. Severe overexposure may result in permanent lung damage. SKIN CONTACT: Brief contact with bare skin may cause mild to moderate irritation, seen as excess redness and possibly swelling at the site of contact. Prolonged contact, as from clothing wet with the material, may result in skin irritation. EYE CONTACT: Causes severe irritation, experienced as discomfort or pain, excess blinking and tear production, marked excess redness and swelling of the conjunctiva, and chemical irritation of the eye. EFFECTS OF REPEATED OVEREXPOSURE: No injury from silica or other dust should occur during reasonable use. If use creates respirable particles, then some respiratory system injury may occur. However, since the silica in this product is compounded into the polymer matrix, it is not expected to present the same hazard as neat silica.

Medical Conditions Generally Aggravated by Exposure
