Chemical dangers
 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (respirable fraction): 0.1 mg/m³; Peak limitation category: I(4);.
MAK (inhalable fraction): 2 mg/m³; Peak limitation category: I(2); Pregnancy risk group: C; (DFG 2009). 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Melting point: 100°C
