HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE      
Inhalation   Use ventilation.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap.

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

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces sulfur oxides and sodium oxides. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
 

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

Effects of short-term exposure
Ingestion could cause effects on the gastrointestinal tract. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 884°C
Relative density (water = 1): 2.7
Solubility in water: very good
