causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: mist 10 mg/m3 as TWA (ACGIH 2005).
MAK: 50 mg/m3 (Inhalable fraction)
Peak limitation category: I(2) Pregnancy risk group: C
(DFG 2006).

Routes of Exposure:
Inhalation Risk:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying.
