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:
Lungs may be affected by repeated or prolonged exposure to dust particles, resulting in a benign pneumoconiosis (stannosis).
