Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaledFresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention. See Notes.
In case of skin contactFirst rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Put clothes in sealable container. Refer immediately for medical attention.
In case of eye contactRinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
If swallowedRinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.
4.2 Most important symptoms/effects, acute and delayedInhalation exposure to 11-23 mg/m3 produces severe choking. 30-60 mg/m3 is extremely dangerous. 200 mg/m3 is fatal in a short time. Vapors can cause acute as well as chronic poisoning. It has cumulative properties. It is irritating to the eyes and respiratory tract. Poisoning is due to the corrosive action on the gastrointestinal tract. Nervous, circulatory and renal disturbances occur after ingestion. Ingestion of liquid can cause death due to circulatory collapse and asphyxiation from swelling of the respiratory tract. The lowest oral lethal dose reported for humans is 14 mg/kg. The lowest lethal inhalation concentration reported for humans is 1000 ppm. (EPA, 1998)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryImmediate 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/
5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing mediaIf material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty). Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use water spray to knock-down vapors.
5.2 Specific hazards arising from the chemicalWill cause ignition of organic materials spontaneous ignition possible when combined with potassium, phosphorus and tin and a wide variety of other chemicals. It reacts explosively with acetylene, acrylonitrile, ammonia, dimethyl formamide, ethyl phosphine, hydrogen, isobutyrophenone, nickel carbonyl, nitrogen triiodide, ozone, oxygen difluoride, phosphorus, potassium, silver azide, sodium and sodium carbide. When heated it emits highly toxic fumes and will react with water or steam to product toxic and corrosive fumes. Bromine is incompatible with a wide variety of materials including alkali hydroxides; arsenites; ferrous, mercurous salts; hypophosphites and other oxidizable substances. Vaporizes rapidly at room temperature. (EPA, 1998)
5.3 Special protective actions for fire-fightersWear self-contained breathing apparatus for firefighting if necessary.

10.3 Possibility of hazardous reactionsThe vapour is heavier than air.BROMINE is a powerful oxidizing agent. Reacts vigorously with reducing reagents. Can ignite a combustible material upon contact. If heated by itself or if mixed with water or steam, highly toxic and corrosive fumes are emitted. Reacts explosively with hydrogen, diethylzinc, dimethylformamide, ammonia, trimethylamine, nitromethane, metal azides (silver or sodium azide). Mixtures with lithium or sodium are shock-sensitive. Ignites on contact with germanium, trialkyl boranes, copper and alkali metal acetylides [Sax, 9th ed., 1996, p. 506]. Attacks most metals, including platinum and palladium [Hawley]. May react violently to form bromides upon contact with Mg, Sr, B, Al, Hg, Ti, Sn, Sb in powder or sheet form. Sodium, potassium, antimony and germanium ignite in bromine vapor and react explosively. Ignites on contact with germanium, trialkyl boranes, copper and alkali metal acetylides [Sax, 9th ed., 1996, p. 506]. Violent reaction with methanol, ethanol, aldehydes, ketones, carboxylic acids, diethyl ether, carbonyl compounds, tetrahydrofuran, acrylonitrile, ozone, phosphorus. Methyl acetylides or carbides ignite at room temperature on contact with bromine vapor. Explosive reaction with red phosphorus, metal azides, nitromethane, silane and its homologues [Bretherick, 5th ed., 1995, p. 109]. Reacts violently on contact with natural rubber [Pascal, 1960, vol. 16.1, 371].
