Potential health effects

Dust from this product is a powerful systemic poison, causing headache, dizziness, and unconsciousness. It is highly corrosive to eyes and skin.

Principle Routes of Exposure

Skin contact with possible absorption through skin, inhalation of dust, and possible ingestion. Human Effects: High alkalinity makes this product corrosive to mucous membranes - chemical burns result from contact. Dust causes irritation to the conjunctiva and cornea of the eye and to respiratory passages. In acute over-exposure, victim experiences headache, nausea, dizziness, confusion, and weakness of the extremities, followed by a precipitous lapse into unconscious- ness. Acute Inhalation: Severe respiratory distress, confusion, weakness of the extremities, uncon- sciousness, pulmonary edema, asphyxiation and possible central respiratory paralysis leading to death. Chronic Inhalation: Extreme irritation to respiratory passages. Acute Skin Contact: Painful chemical burns. Systemic posioning by sulfide causes headache, nausea, dizziness, confusion, weakness of the extremities, and possible unconsciousness. Chronic Skin Contact: Extreme irritation to skin. Acute Eye Contact: Alkali burns to conjunctiva and cornea with possible irreversible destruc- tion of tissue. Chronic Eye Contact: Extreme irritation to the eyes caused by dusts; corneal opacity. Acute Ingestion: Destruction of the lining of the esophagus and stomach. Rapid breathing, confusion, unconsciousness, paralysis of respiratory muscles leading to death. Chronic Ingestion: Headache, nausea, dizziness, confusion, and painful alkali burns to the esophagus. Carcinogenicity NTP.......... Not listed IARC.........: Not listed. OSHA.......: Not regulated.
