Listed as a hazardous air pollutant (HAP) generally known or suspected to cause serious health problems. The Clean Air Act, as amended in 1990, directs EPA to set standards requiring major sources to sharply reduce routine emissions of toxic pollutants.

highly toxic

IDENTIFICATION AND USE: Antimony trifluoride exists in three known crystallin modifications. It is used to catalyze fluorinations by hydrogen fluoride, manufacture of chlorofluorides, in dyeing, usually in form of double salts, manufacture of pottery and porcelains. HUMAN STUDIES: Symptoms of exposure include severe gastritis or gastroenteritis with abdominal pain, retching, and prolonged vomiting, beginning 10-60 min after ingestion. Vomitus may become bloody. Diarrhea is observed, and the feces are watery and later tarry. Dehydration becomes intense. The exposure could further progress to shock, pallor, cyanosis, and coldness, rapid, weak or imperceptible pulse, low blood pressure, rapid and shallow respirations. Sometimes breathing is deep and rapid, reflecting an accompanying metabolic acidosis. Drowsiness, hyporeflexia, dilated pupils, coma could be observed. Vasomotor instability, shock or coma, and a serum iron level in great excess of the total iron binding capacity are poor prognostic signs. Liver injury can occur, consisting of hemorrhagic necrosis which is usually reversible. Death from shock, usually in 4-5 hr. Sometimes following apparent recovery, pneumonia with fever or secondary shock may cause death 1-3 days later. Among survivors, pyloric stenosis and mild hepatic cirrhosis may be encountered as persistent sequelae, but recovery is usually complete. ANIMAL STUDIES: Intratracheal administration in rats produced death at all doses greater than 1.5 mg. Lung, adrenal, and kidney weights increased in the antimony trifluoride-treated animals. In acute fluoride poisoning, fluoride ion increases capillary permeability and also produces a coagulation defect. These actions lead to hemorrhagic gastroenteritis and hemorrhages, congestion, and edema in various organs including the brain. Clinical manifestations include excitability, muscle tremors, weakness, urination, defecation, salivation, emesis, sudden collapse, clonic convulsions, coma, and death due to respiratory and cardiac failure. Chronic manifestations of excess fluoride in cattle are dental fluorosis and osteofluorosis. Chronic inhalation of subtoxic doses of antimony salts causes interstitial pneumonitis, intraalveolar lipoid deposits, and liver and cardiac damage.

Resemble those of lead and arsenic poisoning. ACUTE POISONING: irritation of the mouth, nose, stomach and intestines; vomiting, purging with bloody stools; slow pulse and low blood pressure; slow, shallow breathing; coma and convulsions sometimes followed by death from cardiac and respiratory exhaustion. CHRONIC POISONING: dryness of throat; pain on swallowing; occasional vomiting and persistent nausea; susceptibility to fainting; diarrhea, loss of appetite and weight; giddiness; dermatitis, either pustular or ulcerative; anemia (USCG, 1999)|Corrosives

If any symptoms, however slight, are noticed, the affected individual should be removed from contact with the chemical and placed under the care of a physician who is versed in the treatment necessary. (USCG, 1999)

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Fluorine and related compounds/|Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary.

Stibine, trifluoro-: ACTIVE|Antimony can be trivalent or pentavalent in compounds. Both exist in antimony(IV) oxide, Sb2O4, and presumably in the deep violet haloantimonates (IV), such as Cs2(SbCl6). The pentavalent compounds, as well as most of the trivalent ones, are hydrolyzed by water to form antimony salts, e.g., SbOCl, and hydrated oxides. The only halides of antimony that have any industrial significance are the chlorides and fluorides. /Antimony compounds/
