Fumes in air to form small amounts of hydrogen fluoride (reacts with moisture in air). May React with water to give hydrofluoric acid (HF) [Merck 11th ed. 1989]. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Fluoride gas will be created in 1.2 minutes.

IDENTIFICATION AND USE: Antimony pentafluoride is a hygroscopic, viscous liquid. It is used in the fluorination of organic compounds. HUMAN STUDIES: It is a corrosive liquid to skin, eyes, mucous membranes. ANIMAL STUDIES: Distribution in rats after chronic poisoning by inhalation of antimony pentafluoride showed high antimony concentration in blood. Levels in liver, kidneys, spleen and pancreas were similar. The antimony was retained for a long time and could be detected in organs under examination one month after experiment discontinued.

Antimony pentafluoride's production and use in the fluorination of organic compounds(1) may result in its release to the environment through various waste streams(SRC).

Distribution in rats after chronic poisoning by inhalation of antimony pentafluoride showed high antimony concentration in blood. Levels in liver, kidneys, spleen and pancreas were similar. The antimony was retained for a long time and could be detected in organs under examination one month after experiment discontinued.

The compound is irritating to eyes, skin, and lungs. Contact with eyes or skin causes severe burns. The compound is extremely toxic with a probable oral lethal dose of 5-50 mg/kg or between 7 drops and one teaspoonful for a 150 pound person (antimony salts). (EPA, 1998)

Warning: Antimony Pentafluoride is highly corrosive to the eyes, skin, and lungs, and is extremely toxic if swallowed. The estimated lethal dose after ingestion is between 7 drops and one teaspoonful for a 150 pound person. Signs and Symptoms of Antimony Pentafluoride Exposure: Acute exposure to antimony pentafluoride may result in severe eye damage, vomiting, and severe burns of mouth and throat. Over- exposure by any route can cause bloody stools, slow pulse rate, low blood pressure, coma, convulsions, and cardiac arrest. Emergency Life-Support Procedures: Acute exposure to antimony pentafluoride may require decontamination and life support for the victims. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination. Air-purifying or supplied-air respiratory equipment should also be worn, as necessary. Rescue vehicles should carry supplies such as plastic sheeting and disposable plastic bags to assist in preventing spread of contamination. Inhalation Exposure: 1. Move victims to fresh air. Emergency personnel should avoid self-exposure to antimony pentafluoride. 2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support. 3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures. 4. Rush to a health care facility. Dermal/Eye Exposure: 1. Remove victims from exposure. Emergency personnel should avoid self-exposure to antimony pentafluoride. 2. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support. 3. Remove contaminated clothing as soon as possible. 4. If eye exposure has occurred, eyes must be flushed with lukewarm water for at least 15 minutes. 5. Wash exposed skin areas thoroughly with soap and water. 6. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures. 7. Rush to a health care facility. Ingestion Exposure: 1. Evaluate vital signs including pulse and respiratory rate, and note any trauma. If no pulse is detected, provide CPR. If not breathing, provide artificial respiration. If breathing is labored, administer 100% humidified oxygen or other respiratory support. 2. DO NOT induce vomiting or attempt to neutralize. 3. Obtain authorization and/or further instructions from the local hospital for administration of an antidote or performance of other invasive procedures. 4.

Antimony fluoride (SbF5): 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/
