Information OSHA Effects of Overexposure Skin Contact: Information Effects of Overexposure Skin Contact: Contact with skin may be irritating. Material may be absorbed through the skin in harmful amounts. Poisoning symptoms parallel those of ingestion. Eye Contact: Contact may be irritating to the eyes. Ingestion: Harmful or fatal if swallowed. Symptoms of poisoning include metallic taste in the mouth, garlic odor on the breath, nervousness, excessive thirst, vomiting, diarrhea, cyanosis. May be followed by collapse and unconsciousness. Inhalation: Aqueous solutions do not typically present an inhalation hazard, however, if conditions of use generate fumes or vapors they may be harmful or fatal if inhaled. Vapors may cause poisoning symptoms that parallel those of ingestion. Storage and Handling Precautions Store in a cool, dry well-ventilated area or cabinet dedicated to toxic storage. Isolate away from incompatible materials. Keep containers well closed.
