TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances.  NO contact with combustible substances.  In case of fire in the surroundings: water in large amounts, water spray. 
EXPLOSION Risk of fire and explosion. See Chemical Dangers.    In case of fire: keep drums, etc., cool by spraying with water. NO direct contact of the substance with water. 
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain. Blurred vision.  Wear safety goggles or eye protection in combination with breathing protection.  Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion Sore throat. Burning sensation. Abdominal pain.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL

IMPORTANT DATA
Physical State; Appearance
WHITE CRYSTALLINE POWDER. 

Physical dangers
No data. 

Chemical dangers
Decomposes on contact with water. This generates fire and explosion hazard. The solution in water is a weak base. Reacts with metal and their salts, organic acids and reducing agents. 

Occupational exposure limits
TLV not established.
MAK (not established):. 

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
The substance is severely irritating to the eyes. The substance is irritating to the respiratory tract. The substance is mildly irritating to the skin. 

Effects of long-term or repeated exposure
Lungs may be affected by repeated or prolongated exposure. Repeated or prolonged contact with skin may cause dermatitis. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: No melting point; decomposes at >50°C
See Notes.
Density: 2.1 g/cm³
Solubility in water, g/100ml at 20°C: 14 (good)
Vapour pressure, Pa at 25°C: (negligible) 
The substance is toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. 

NOTES
If the temperature exceed 50°C a self-accelarating decomposition can occur, releasing heat, oxygen and steam. See Sodium carbonate ICSC 1135. See Hydrogen peroxyde ICSC 0164.
