Common Name: Antimony Tribromide CAS Number: 7789-61-9 DOT Number: NA 1549 Date: August 1, 1987 ----------------------------------------- HAZARD SUMMARY * Antimony Tribromide can affect you when breathed and by passing through skin. * Exposure can cause sore throat, skin rash, poor appetite and irritation of the air passages with cough. Higher exposures can cause a buildup of fluid in the lungs or irregular heartbeat. This can cause death. * High or repeated exposure may damage the liver and the heart muscle. * Antimony Tribromide is a CORROSIVE Chemical and contact can burn the skin and eyes, with possible damage. * If used near acid, a deadly gas (Stibine) can be released. IDENTIFICATION Antimony Tribromide is a yellow crystal (sugar or sand-like) material. It is used to make Antimony salts and in dyeing and analytical chemistry. REASON FOR CITATION * Antimony Tribromide is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT and NIOSH. * This chemical is on the Special Health Hazard Substance List because it is CORROSIVE. HOW TO DETERMINE IF YOU ARE BEING EXPOSED * Exposure to hazardous substances should be routinely evaluated. This may include collecting personal and area air samples. You can obtain copies of sampling results from your employer. You have a legal right to this information under OSHA 1910. 20. * If you think you are experiencing any work-related health problems, see a doctor trained to recognize occupational diseases. Take this Fact Sheet with you. ----------------------------------------- WORKPLACE EXPOSURE LIMITS These exposure limits are recommended for Antimony and compounds as Stibine. OSHA: The legal airborne permissible exposure limit (PEL) is 0.5 mg/m3 averaged over an 8 hour workshift. NIOSH: The recommended airborne exposure limit is 0.5 mg/m3 averaged over a 10 hour workshift. ACGIH: The recommended airborne exposure limit is 0.5 mg/m3 averaged over an 8 hour workshift. * The above exposure limits are for air levels only. When skin contact also occurs, you may be overexposed, even though air levels are less than the limits listed above. WAYS OF REDUCING EXPOSURE * Where possible, enclose operations and use local exhaust ventilation at the site of chemical release. If local exhaust ventilation or enclosure is not used, respirators should be worn. * Wear protective work clothing. * Wash thoroughly immediately after exposure to Antimony Tribromide and at the end of the workshift. * Post hazard and warning information in the work area. In addition, as part of an ongoing education and training effort, communicate all information on the health and safety hazards of Antimony Tribromide to potentially exposed workers. This Fact Sheet is a summary source of information of all potential and most severe health hazards that may result from exposure. Duration of exposure, concentration of the substance and other factors will affect your susceptibility to any of the potential effects described below. ------------------------------------------ HEALTH HAZARD INFORMATION Acute Health Effects The following acute (short-term) health effects may occur immediately or shortly after exposure to Antimony Tribromide: * Exposure can cause sore throat and airway irritation, with cough. Nausea and metallic taste may occur. Higher levels may cause fluid in the lungs and may cause the heart to beat irregularly or stop. These can cause death. * Contact can burn the skin or eyes with possible permanent damage. Chronic Health Effects The following chronic (long-term) health effects can occur at some time after exposure to Antimony Tribromide and can last for months or years: Cancer Hazard * According to the information presently available to the New Jersey Department of Health, Antimony Tribromide has not been tested for its ability to cause cancer in animals. Reproductive Hazard * According to the information presently available to the New Jersey Department of Health, Antimony Tribromide has not been tested for its ability to adversely affect reproduction. Other Long-Term Effects * Repeated exposure can cause headaches, poor appetite, dry throat and lack of sleep. Damage to the liver and heart muscle may also occur, especially with frequent or higher exposures. * Very irritating substances may affect the lungs. It is not known whether Antimony Tribromide causes lung damage. MEDICAL Medical Testing For those with frequent or potentially high exposure (half the TLV or greater), the following are recommended before beginning work and at regular times after that: * Urine test for Antimony. * Consider lung function tests. If symptoms develop or overexposure is suspected, the following may be useful: * EKG. * Liver function tests. * Consider chest x-ray after acute overexposure. Any evaluation should include a careful history of past and present symptoms with an exam. Medical tests that look for damage already done are not a substitute for controlling exposure. Request copies of your medical testing. You have a legal right to this information under OSHA 1910.20. Mixed Exposures * Use of Antimony Tribromide near acid can cause release of a deadly gas, Stibine. * Exposed persons should avoid frequent use of Bromoselzer or other Bromine medication (such as some sleeping pills), without medical advice. WORKPLACE CONTROLS AND PRACTICES Unless a less toxic chemical can be substituted for a hazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary. In evaluating the controls present in your workplace, consider: (1) how hazardous the substance is, (2) how much of the substance is released into the workplace and (3) whether harmful skin or eye contact could occur. Special controls should be in place for highly toxic chemicals or when significant skin, eye, or breathing exposures are possible. In addition, the following controls are recommended: * Where possible, automatically transfer Antimony Tribromide from drums or other storage containers to process containers. * Specific engineering controls are recommended for this chemical by NIOSH Refer to the NIOSH criteria document: Antimony #78-216. Good WORK PRACTICES can help to reduce hazardous exposures. The following work practices are recommended: * Workers whose clothing has been contaminated by Antimony Tribromide should change into clean clothing promptly. * Contaminated work clothes should be laundered by individuals who have been informed of the hazards of exposure to Antimony Tribromide. * Eye wash fountains should be provided in the immediate work area for emergency use. * If there is the possibility of skin exposure, emergency shower facilities should be provided. * On skin contact with Antimony Tribromide, immediately wash or shower to remove the chemical. * Do not eat, smoke, or drink where Antimony Tribromide is handled, processed, or stored, since the chemical can be swallowed. Wash hands carefully before eating or smoking. PERSONAL PROTECTIVE EQUIPMENT WORKPLACE CONTROLS ARE BETTER THAN PERSONAL PROTECTIVE EQUIPMENT. However, for some jobs (such as outside work, confined space entry, jobs done only once in a while, or jobs done while workplace controls are being installed), personal protective equipment may be appropriate. The following recommendations are only guidelines and may not apply to every situation. Clothing * Avoid skin contact with Antimony Tribromide. Wear protective gloves and clothing. Safety equipment suppliers/ manufacturers can provide recommendations on the most protective glove/ clothing material for your operation. * All protective clothing (suits, gloves, footwear, headgear) should be clean, available each day and put on before work. Eye Protection * Wear dust-proof goggles and face shield when working with powders or dust, unless full facepiece respiratory protection is worn. Respiratory Protection * IMPROPER USE OF RESPIRATORS IS DANGEROUS. Such equipment should only be used if the employer has a written program that takes into account workplace conditions, requirements for worker training, respirator fit testing and medical exams, as described in OSHA 1910.134. * Where the potential exists for exposures over 0.5 mg/m3 use a MSHA/NIOSH approved full facepiece respirator with a high efficiency particulate filter. Greater protection is provided by a powered-air purifying respirator. * If while wearing a filter, cartridge or canister respirator, you can smell, taste, or otherwise detect Antimony Tribromide, or in the case of a full facepiece respirator you experience eye irritation, leave the area immediately. Check to make sure the respirator-to-face seal is still good. If it is, replace the filter, cartridge, or canister. If the seal is no longer good, you may need a new respirator. * Be sure to consider all potential exposures in your workplace. You may need a combination of filters, prefilters, cartridges, or canisters to protect against different forms of a chemical (such as vapor and mist) or against a mixture of chemicals.

As antimony oxide, it is added to various materials as a flame retardant. Antimony may occur in the aquatic environment from natural weathering of mineral formations, from mining and manufacturing effluents, and from municipal wastes. ACUTE (SHORT-TERM) ECOLOGICAL EFFECTS Acute toxic effects may include the death of animals, birds, or fish, and death or low growth rate in plants. Acute effects are seen two to four days after animals or plants come in contact with a toxic chemical substance. Antimony has high acute toxicity to aquatic life. No data are available on the short-term effects of antimony to plants, birds, or land animals. CHRONIC (LONG-TERM) ECOLOGICAL EFFECTS Chronic toxic effects may include shortened lifespan, reproductive problems, lower fertility, and changes in appearance or behavior. Chronic effects can be seen long after first exposure(s) to a toxic chemical. Antimony has high chronic toxicity to aquatic life. No data are available on the long-term effects of antimony to plants, birds, or land animals. WATER SOLUBILITY Antimony and its salts have solubilities in water ranging from low to high. DISTRIBUTION AND PERSISTENCE IN THE ENVIRONMENT Antimony is highly persistent in water with a half-life of longer than 200 days. The half-life of a pollutant is the amount of time it takes for one-half of the chemical to be degraded. BIOACCUMULATION IN AQUATIC ORGANISMS Some substances increase in concentration, or bioaccumulate, in living organisms as they breathe contaminated air, drink contaminated water, or eat contaminated food. These chemicals can become concentrated in the tissues and internal organs of animals and humans. The concentration of antimony found in fish tissues is expected to be about the same as the average concentration of antimony in the water from which the fish was taken.
