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.
