### IMPORTANT DATA

Physical State; Appearance COLOURLESS CRYSTALS OR WHITE POWDER.

Physical dangers

Chemical dangers Decomposes on heating. This produces calcium oxide. The solution in water is a medium strong base. Reacts violently with acids. Attacks many metals in the presence of water. This produces flammable/explosive gas (hydrogen - see ICSC 0001).

Occupational exposure limits Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of short-term exposure The substance is corrosive to the eyes and skin. The substance is irritating to the respiratory tract. Medical observation is indicated.

Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged inhalation of of dust particles may cause effects on the lungs.



### PHYSICAL PROPERTIES ENVIRONMENTAL DATA

Decomposes at at 580°C°C Relative density (water = 1): 2.2 Solubility in water: none
