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 Short-Term Exposure:
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
peripheral nervous system
, resulting in
impaired functions
.
