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 substance is irritating to the eyes and skin. The substance may cause effects on the kidneys and blood. This may result in renal failure and the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.	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 Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the kidneys. This may result in renal failure.
