- Antimony trifluoride
Antimony trifluoride, solid is a white to gray crystalline solid.
To catalyze fluorinations by hydrogen fluoride, manufacture of chlorofluorides, in dyeing, usually in form of double salts, eg, antimony sodium fluoride, or antimony fluoride and ammonium sulfate double salt, manufacture of pottery & porcelains.

Hazards and Protection.
Store in a cool, dry place. Keep container closed when not in use. Store in a tightly closed container. Keep away from water. Corrosives area.
Wash thoroughly after handling. Wash hands before eating. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Do not allow water to get into the container because of violent reaction. Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not allow contact with water. Use only in a chemical fume hood. Discard contaminated shoes. Keep from contact with moist air and steam.
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.
Vacuum or sweep up material and place into a suitable disposal container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation. Do not expose spill to water.
Stable under normal temperatures and pressures. Combines vigorously or explosively with water.
Perchloric acid, strong oxidizing agents, water.
Irritating and toxic fumes and gases, hydrogen fluoride, antimony/antimony oxides.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Not flammable, but reacts with most metals to form flammable hydrogen gas. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Use water spray to keep fire-exposed containers cool. May ignite or explode on contact with steam or moist air. Containers may explode when heated or if contaminated with water. Extinguishing media: If water is the only media available, use in flooding amounts. Do NOT get water inside containers. For large fires, use water spray, fog or alcohol-resistant foam. Do NOT use straight streams of water. Most foams will react with the material and release corrosive/toxic gases. Contact professional fire-fighters immediately. Cool containers with flooding quantities of water.
Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases. Reaction with water may generate much heat which will increase the concentration of fumes in the air. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.

Chronic inhalation and ingestion may cause fluorosis with skeletal abnormalities. Chronic inhalation may cause nasal septum ulceration and perforation. Effects may be delayed. Chronic exposure to fluoride compounds may cause systemic toxicity.
May cause severe and permanent damage to the digestive tract. May cause liver damage. May cause perforation of the digestive tract. Inorganic fluorides can be harmful. Acute exposure to fluorine compounds can lead to digestive tract burns, and abdominal pain. Contains fluoride. Fluoride can reduce calcium levels leading to fatal hypocalcemia. May cause systemic effects.
Causes chemical burns to the respiratory tract. Inhalation may be fatal as a result of spasm, inflammation, edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema. Aspiration may lead to pulmonary edema. May cause systemic effects.
Contact with skin causes irritation and possible burns, especially if the skin is wet or moist. May cause skin rash (in milder cases), and cold and clammy skin with cyanosis or pale color.
When substances becomes wet or comes in contact with moisture of the mucous membranes, it becomes an irritant. May cause chemical conjunctivitis and corneal damage.
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. DO NOT use mouth-to-mouth respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes. If water-reactive products are embedded in the skin, no water should be applied. The embedded products should be covered with a light oil.
Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes).
