EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation.
Effects of short-term exposure
Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.
Effects of long-term or repeated exposure The substance may have effects on the peripheral nervous system. This may result in impaired functions.
