Potential health effects

Amorphous fumed silica does not contain crystalline silica. Inhalation: May cause dryness and irritation to mucous membranes, nose, and throat. Symptoms may include coughing, sore throat, dysphea, wheezing, and non-specific chest illnesses. Ingestion: Major hazard is that of the copper iodide component, of which only trace amounts are moderately toxic. Symptoms may include burning pain in the mouth, esophagus, and stomach. Symptoms of copper poisoning include hemorrhagic gastritis, nausea, vomiting, abdominal pain, metallic taste, and diarrhea. Ingestion of very large amounts of sulfur may cause sore throat, nausea, headache, and possibly unconsciousness in severe cases. May be converted into hydrogen sulfide in the intestine. Skin Contact: Causes irritation to skin. Symptoms include redness, itching, and pain. Eye Contact: Causes irritation, redness, and pain. Chronic Exposure: Prolonged overexposure to sulfur dust can produce possible skin sensitization and permanent eye damage(clouding of the lens and chronic irritation). Prolonged inhalation can cause irritation of mucous membranes. Chronic iodide overdoses have produced iodism. Headache, fever, sneezing, salivation, and skin rashes may occur. Prolonged or repeated exposure to dusts of copper salts may cause discoloration of the skin or hair, ulceration and perforation of the nasal septum, runny nose, metallic taste, and atrophic changes and irritation of the mucous membranes. Aggravation of Pre-existing Conditions: Sensitive individuals can experience skin irritation from repeated exposure to sulfur dust. Allergenic responses can occur.
