EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. Effects of short-term exposure The vapour is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. Exposure far above the OEL could cause unconsciousness. The substance may cause effects on the blood. This may result in lesions of blood cells and kidney impairment.	Inhalation risk Effects of long-term or repeated exposure The substance defats the skin, which may cause dryness or cracking. The substance may have effects on the blood. This may result in anaemia and kidney impairment.
