Ammonium bifluoride is not known to bioaccumulate or persist in the environment more than a few days. However it will decompose in moist environments liberating hydrofluoric acid and ammonia. Ammonium bifluoride is corrosive and can corr ode most metals. It is not flammable or explosive. Ammonium bifluoride will react with water (inc luding perspiration) to form hydrofluoric acid. Exposure of ammonium bifluoride to strong acids, strong bases, water or high temperatures can cause decomposition. Decomposition of ammonium bifluoride will result in the liberation of hydrogen fluoride, ammonia and nitrogen oxide gases. The concentrations of ammonium bifluoride typically found in consumer products may pose risk of symptoms due to skin, ingestion or inhalation exposure. Persons suffering from eye or ingestion exposure to consumer strengt h ammonium bifluoride products may experience symptoms similar to persons exposed to industrial strength ammonium bifluoride . Exposures to industrial strength ammonium bifluoride can produce the following adverse health affects: 1. Contact Skin exposures can cause symptoms ranging from minor skin irritation to painful redness and swelling. Severe burns can occur if treatment is delayed after exposure to ammonium bifluoride. Eye expos ure to ammonium bifluoride may result in severe eye irritation, burns or even blindness. 2. Inhalation The inhalation of ammonium bifluoride can cause symptoms ranging from nose and throat irritation to coughing and difficulty breathing. Aspiration may cause pulmonary edema and pneum onitis (fluid on the lungs and inflammation of the lungs). Repeated or prolonged exposur es may cause sore throat, nosebleeds and chronic bronchitis. Prolonged exposure may cause hypocalcemia with nervous problems (tetany) and cardiac arrhythmia (reduced calcium levels, spasms and irregular heart beat). 3. Ingestion The ingestion of ammonium bifluoride may cause burns of the mouth and throat and perforation of the esophagus and stomach. N ausea, bloody vomiting, abdominal pain, diarrhea, difficulty breathing, swelling of the throat, loss of consciousness, coma and heart failure can also occur. The ingestion of ammonium bifluoride may be fatal. 4. Other Effects The International Agency for Research on Cancer (IARC) has not determined ammonium bifluoride to be carcinogenic (cancer causing). During most exposures, ammonium bifluoride will dissoc iate to release hydrofluoric acid. First aid techniques for treatment to hydrof luoric acid exposures are unique. They require a rapid response and the use of calcium (most commonly calcium gluconate solutions or gels) to scavenge and neutralize the fluoride ion.
