  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 organic materials, powdered metals, ammonium salts, combustible substances or reducing agents.  NO open flames. NO contact with flammables. NO contact with hot surfaces.  Do NOT expose to friction or shock.  In case of fire in the surroundings, use appropriate extinguishing media.  In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position. 

 PREVENT DISPERSION OF DUST! STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS 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.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Blue lips, fingernails and skin. Confusion. Convulsions. Diarrhoea. Dizziness. Headache. Nausea. Shortness of breath. Sore throat. Unconsciousness. Vomiting. Symptoms may be delayed. See Notes.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer immediately for medical attention. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Consult an expert! Sweep spilled substance into covered sealable containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS CRYSTALS OR WHITE POWDER. 

Physical dangers
 

Chemical dangers
Decomposes above 400°C . Decomposes on contact with strong acids. This produces oxygen and toxic fumes including chlorine dioxide and chlorine. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. This generates fire and explosion hazard. Attacks many metals in the presence of water. 

Formula: ClKO3 / KClO3
Molecular mass: 122.6
Decomposes at 400°C
Melting point: 368°C
Density: 2.3 g/cm³
Solubility in water, g/100ml: 7.3  


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is irritating to the respiratory tract. The substance may cause effects on the blood and kidneys. This may result in haemolysis, the formation of methaemoglobin and kidney impairment. The effects may be delayed. Medical observation is indicated. 

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

Effects of long-term or repeated exposure
The substance may have effects on the blood. This may result in the formation of methaemoglobin. 


Occupational exposure limits
 

ENVIRONMENT
 

NOTES
Will turn shock-sensitive if contaminated with organic substances, reducing materials, metal powders, ammonium compounds.
Environmental effects from the substance have not been investigated adequately.
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Rinse contaminated clothing with plenty of water because of fire hazard.
