Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic and corrosive fumes including sulfur oxides. Reacts with bases. Reacts violently with strong oxidants. This produces heat. This produces toxic and corrosive fumes including sulfur oxides. The solution in water is a medium strong acid. Attacks many metals in the presence of water. 

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

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and 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, respiratory tract and gastrointestinal tract. The substance is mildly irritating to the skin. 

Effects of long-term or repeated exposure
The substance may have effects on the central nervous system. This may result in impaired functions. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 770°C
Density: 2.71 g/cm³
Solubility in water: good
See Notes. 
The substance is toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment. 

NOTES
Occurs in nature as the mineral alunogenite.
Other CAS numbers: 16828-12-9 (14-hydrate); 16828-11-8 (16-hydrate); 7784-31-8 (18-hydrate); 17927-65-0 (x-hydrate).
Aluminium sulfate hydrolizes in water forming sulfuric acid and heat. Literature values for solubility of the substance are very different due to hydrolyzation process.
