EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of fume and through the skin. 

Effects of short-term exposure
The substance is irritating to the eyes and skin. 

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

Effects of long-term or repeated exposure
May cause chloracne. The substance may have effects on the liver. This may result in liver impairment. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.5 mg/m3, as TWA; (skin)
