TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with flammables. NO contact with strong reducing agents, strong bases, ammonia, urea or water.  Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Risk of fire and explosion on contact with strong reducing agents, strong bases, ammonia, urea or water.    In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness. Skin burns. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Loss of vision. Severe deep burns.  Wear 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 refer for medical attention. 
Ingestion Burning sensation. Sore throat.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALLINE POWDER WITH PUNGENT ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on contact with water. This produces toxic fumes including chlorine. The substance is a strong oxidant. It reacts violently with combustible and reducing materials. Reacts violently with many substances. This generates fire and explosion hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

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

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. Corrosive on ingestion. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 230°C
Relative density (water = 1): >1
Solubility in water, g/100ml: 25  
This substance may be hazardous to the environment. Special attention should be given to water quality. 

NOTES
Also consult ICSC 0126 Chlorine.
Card has been partly updated in October 2005.
