IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-WHITE CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces sulfur 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 when dispersed, especially if powdered. 

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

Effects of long-term or repeated exposure
