  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion on contact with combustible substances or reducing agents.  NO contact with combustible substances or reducing agents.    Use water in large amounts.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles 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 refer for medical attention. 
Ingestion Abdominal pain. Diarrhoea. Nausea. Vomiting.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents. Personal protection: P3 filter respirator for toxic particles. 

According to UN GHS Criteria

 

Transportation
UN Classification
UN Hazard Class: 5.1; UN Pack Group: II 

STORAGE
Separated from combustible substances, reducing agents, powdered metals and incompatible materials. See Chemical Dangers.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
WHITE CRYSTALS OR POWDER. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. Reacts violently with aluminium, disulfur dibromide, arsenic, carbon, copper, metal sulfides, phosphorus and sulfur. This generates fire hazard. 

Formula: KBrO3
Molecular mass: 167.0
Decomposes at 370°C
Melting point: 350°C
Density: 3.27 g/cm³
Solubility in water, g/100ml at 25°C: 7.5  


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Ingestion could cause effects on the kidneys and central nervous system. This may result in renal failure, respiratory depression and hearing loss. The effects may be delayed. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
This substance is possibly carcinogenic to humans. 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
 

NOTES
Will turn shock-sensitive if contaminated with organic substances.
Rinse contaminated clothes (fire hazard) with plenty of water.
