Potential health effects

Eye May cause chemical conjunctivitis and corneal damage Skin May cause irritation and dermatitis; may cause cyanosis of the extremities Ingestion May cause gastrointestinal irritation with nausea, vomiting and diarrhea, ingestion of large amounts may cause CNS depression Inhalation Aspiration may lead to pulmonary edema. Contains crystalline silica, which may lead to respiratory abnormalities and silicosis. Inhalation of dusts causes severe irritation of the upper respiratory tract, gastrointestinal disturbances, albuminuria, gradual loss of weight, and increasing weakness. May cause burning sensation in the chest. Chronic Chronic inhalation of dust may lead to silicosis. May cause silicosis-disabling pulmonary fibrosis characterized by fibrotic changes and miliary nodules in the lungs, dry cough, shortness of breath, emphysema, decreased chest expansion and increased susceptibility to tuberculosis.
