HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough. Sore throat.  Avoid inhalation of dust and mist. Use local exhaust or breathing protection.   
Skin Dry skin. Redness.  Protective gloves.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. 
Eyes   Wear safety goggles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.

IMPORTANT DATA
Physical State; Appearance
VERY HYGROSCOPIC SOLID IN VARIOUS FORMS. 

Physical dangers
 

Chemical dangers
The substance is a strong reducing agent. It reacts violently with oxidants. The substance may reduce the oxygen content of air in confined spaces. Reacts with water. This produces flammable/explosive gas (hydrogen - see ICSC 0001). 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

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

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

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 1300°C
Melting point: 824°C
Density: 2.8 g/cm³
Solubility in water: very good 
It is strongly advised not to let the chemical enter into the environment because it is persistent. 

NOTES
Health effects of exposure to the substance have not been investigated adequately.
