Health hazards

Information OSHA Effects of Overexposure Skin Contact: Contact may cause skin irritation. Eye Contact: Information Eye Contact: Contact may be irritating to the eyes. Ingestion: Ingestion of large quantities may cause gastrointestinal irritation, nausea and vomiting. Inhalation: Inhalation may irritate the nose, throat and upper respiratory tract.

Potential chronic health

of Overexposure Chronic manganese poisoning can result from excessive inhalation exposure. Manganese poisoning may impair the central nervous system. Symptoms include sluggishness, sleepiness and weakness in legs. Advanced cases show symptoms similar to Parkinson's disease.
