EXPOSURE & HEALTH EFFECTS

Routes of exposure
 

Effects of short-term exposure
The substance is irritating to the eyes. 

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying. 

Effects of long-term or repeated exposure
