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 mildly irritating to the eyes and skin.	Inhalation risk A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. Effects of long-term or repeated exposure The substance may have effects on the liver. This may result in liver impairment.
