EXPOSURE & HEALTH EFFECTS
Routes of exposure Effects of short-term exposure May cause mechanical irritation to the respiratory tract.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered. 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).

EXPOSURE & HEALTH EFFECTS

Routes of exposure

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

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

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).

OCCUPATIONAL EXPOSURE LIMITS
TLV: 2 mg/m³, as TWA. EU-OEL: 2 mg/m³ as TWA

ENVIRONMENT
