EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the nervous system and kidneys. Animal tests show that this substance possibly causes toxicity to human reproduction or development. 


Occupational exposure limits
