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

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance may cause effects on the central nervous system, cardiovascular system and blood. This may result in formation of methaemoglobin. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the central nervous system, cardiovascular system and blood. This may result in formation of methaemoglobin.
