SRP: Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in air, soil or water; effects on animal, aquatic and plant life; and conformance with environmental and public health regulations. If it is possible or reasonable use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination.|After the material has been contained, remove it, and the contaminated soil and place in impervious containers. If practical, transport material back to the supplier, or chemical company to recover the heavy-metal content and deactivate. If this is not practical, or facilities not available, the material should be encapsulated and buried in a specially designated chemical landfill. Material is not acceptable at sewage treatment plants.|Product Offer surplus and non-recyclable solutions to a licensed disposal company.

Excerpt from ERG Guide 157 [Substances - Toxic and/or Corrosive (Non-Combustible / Water-Sensitive)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. FIRE: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2016)

Excerpt from ERG Guide 157 [Substances - Toxic and/or Corrosive (Non-Combustible / Water-Sensitive)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. A vapor-suppressing foam may be used to reduce vapors. DO NOT GET WATER INSIDE CONTAINERS. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. Prevent entry into waterways, sewers, basements or confined areas. SMALL SPILL: Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean, non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal. (ERG, 2016)

Gloves, dustproof clothing, goggles, and, where atmospheric exposure is high, respirators should be used. (USCG, 1999)|Eye/face protection: Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).|Skin protection: Handle with gloves.|Body Protection: Complete suit protecting against chemicals. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.|Respiratory protection: For nuisance exposures use type P95 (US) or type P1 (EU EN 143) particle respirator. For higher level protection use type OV/AG/P99 (US) or type ABEK-P2 (EU EN 143) respirator cartridges. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).|For more Personal Protective Equipment (PPE) (Complete) data for Antimony tribromide (12 total), please visit the HSDB record page.

Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Advice for firefighters: Wear self-contained breathing apparatus for firefighting if necessary.

ACCIDENTAL RELEASE MEASURES; Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Avoid breathing dust. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Methods and materials for containment and cleaning up: Pick up and arrange disposal without creating dust. Sweep up and shovel. Keep in suitable, closed containers for disposal.

SRP: The scientific literature for the use of contact lenses by industrial workers is inconsistent. The benefits or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.|SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants. Ensure that the local ventilation moves the contaminant away from the worker.|Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands.|Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.|For more Preventive Measures (Complete) data for Antimony tribromide (9 total), please visit the HSDB record page.

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. EPA is required to establish and phase in specific performance based standards for all air emission sources that emit one or more of the listed pollutants. Antimony compounds are included on this list. /Antimony Componds/

highly toxic

IDENTIFICATION AND USE: Antimony tribromide is a yellow or colorless solid. It is used in analytical chemistry, as a mordant, in manufacture of antimony salts. HUMAN STUDIES: Inhalation causes coughing, choking, and variable symptoms of headache, dizziness, and weakness followed by pulmonary edema, difficult breathing, cyanosis, and bloody sputum. Skin contact causes severe burns. Burns heal slowly with scar formation. May produce anemia and bloody urine. ANIMAL STUDIES: Chronic inhalation of subtoxic doses of antimony salts causes interstitial pneumonitis, intraalveolar lipoid deposits, and liver and cardiac damage.

INHALATION: Inflammation of mucous membranes of nose and throat. SKIN: Irritation and eczematous eruption. INGESTION: Gastro intestinal upset, vomiting, diarrhea. Nervous complaints such as irritability, sleeplessness, fatigue, muscular and neurologic pain. (USCG, 1999)

Call a physician. INHALATION: Remove from exposure. SKIN: Flush with copious amounts of water. INGESTION: Have victim drink water or milk. Induce vomiting. Perform gastric lavage. (USCG, 1999)

Call for medical aid. ... Move to fresh air. If swallowed and victim is conscious, have victim drink water or milk. Flush affected areas with plenty of water.|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. /Bromine, methyl bromide, and related compounds/|Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary.

Stibine, tribromo-: 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/
