International Chemical Safety Cards SODIUM BROMATE ICSC: 0196 NaBrO3 Molecular mass: 150.9 ICSC #    0196 CAS #     7789-38-0 RTECS # EF8750000 UN #        1494 March 13, 1995 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. NO contact with combustible substances. Water in large amounts. EXPLOSION Risk of fire and explosion on contact with combustible, organic or other easily oxidizable materials. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Sore throat. Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention.  •SKIN Redness. Protective gloves. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Face shield or eye protection in combination with breathing protection if powder. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Abdominal pain. Diarrhoea. Nausea. Vomiting. Oliguria. Do not eat, drink, or smoke during work. Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Do NOT wash away into sewer. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT absorb in saw-dust or other combustible absorbents (extra personal protection: P3 filter respirator for toxic particles). Separated from combustible and reducing substances.

International Chemical Safety Cards SODIUM BROMATE ICSC: 0196 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALS. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating or on burning producing toxic and corrosive fumes. The substance is a strong oxidant and reacts violently with combustible and reducing materials, fuels and metal powder, grease, sulphur containing compounds causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the kidneys, gastrointestinal tract and central nervous system by ingestion. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Melting point (decomposes): 381°C Relative density (water = 1): 3.34 Solubility in water: good ENVIRONMENTAL DATA N O T E S Will turn shock-sensitive if contaminated with organic substances. Rinse contaminated clothes (fire hazard) with plenty of water. ADDITIONAL INFORMATION ICSC: 0196 SODIUM BROMATE (C) IPCS, CEC, 1994
