TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking. NO contact with acids or oxidizing agents.  Use water in large amounts, water spray, foam, dry powder. 
EXPLOSION      
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Burning sensation. Laboured breathing. Shortness of breath. Sore throat.  Use closed system or ventilation.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain. Skin burns. Blisters.  Protective gloves. Protective clothing.  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. Blurred vision. Severe deep burns.  Wear face shield or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. Burning sensation. Shock or collapse.  Do not eat, drink, or smoke during work.  Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
WHITE-TO-YELLOW HYGROSCOPIC CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on burning. Decomposes on contact with acids or water. This produces toxic and corrosive gases. This increases fire hazard. The solution in water is a strong base. It reacts violently with acid and is corrosive. Reacts violently with oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

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

Effects of long-term or repeated exposure
