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. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 3 mg/m3, as TWA; A4 (not classifiable as a human carcinogen) 

ENVIRONMENT
The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use.
