Routes of exposure
 

Inhalation risk
A harmful 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. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of dust particles may cause effects on the lungs. This may result in a benign pneumoconiosis (stannosis).
