Note to physician: Treat as per an accident involving hydrofluoric acid. Potential Health Effects Eyes: Corrosive. Causes eye damage. Wear splash proof goggles or side shield safety glasses. Provide convenient eyewash stations. Skin: Corrosive. Ammonium bifluoride causes severe necrosis to tissues (like hydrofluoric acid.) The calcium and magnesium ions of the tissues will be captured. Ingestion: Corrosive. Causes burning in mouth and throat. Do not induce vomiting. Immediately give two glasses of water or activated charcoal slurry. An alternate is magnesia (one tablespoon in a glass of water) or, preferably, a solution of calcium gluconate. Get medical attention immediately. Inhalation: Corrosive! Breathing of vapor can cause respiratory irritation and inflammation. Take immediately to a physician. Chronic Exposure: SKIN: May cause skin irritation with discomfort or rash or skin burns or ulceration. EYES: May cause eye irritation with discomfort, tearing, or blurring of vision; or eye corrosion with cornea or conjunctival ulceration. INHALATION: May cause irritation of the upper respiratory passages with coughing and discomfort; or temporary nervous system depression with anaesthetic effects such as dizziness, headache, confusion, incoordination, and loss of consciousness. Inhalation of ammonium bifluoride may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema. Symptoms exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting. Chronic exposure to fluoride may cause fluorosis with weight loss, anemia, weakness, general ill health, stiffness of joints. INGESTION: May cause upper gastrointestinal irritation or corrosion of mucous membranes with stomach discomfort, nausea and prostration or abnormal liver function as detected by laboratory tests. Fatality may occur from gross overexposure.
