IMPORTANT DATA
Physical State; Appearance
WHITE POWDER OR PELLETS. 

Physical dangers
No data. 

Chemical dangers
Decomposes above 825°C . This produces corrosive fumes of calcium oxide. Reacts with acids, aluminium, ammonium salts, fluorine and magnesium. 

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

Routes of exposure
 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 

Effects of short-term exposure
May cause mechanical irritation to the respiratory tract and eyes. 

Effects of long-term or repeated exposure
Health effects of the substance have been investigated but none have been found 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 825°C
Density: 2.8 g/cm³
Solubility in water, mg/l at 25°C: 14 (very poor) 
Environmental effects from the substance have not been investigated adequately. 

NOTES
Calcium carbonate exists in nature as mineral aragonite and calcite (as in limestone, chalk and marble).
