Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including sulfur oxides. Reacts with moist air. This produces toxic 3-propane sulfonic acid. 

Occupational exposure limits
TLV (L): A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: Carcinogen category: 2; Skin absorption (H); (DFG 2003). 

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 mildly irritating to the eyes and skin. 

Effects of long-term or repeated exposure
This substance is possibly carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
