Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
Physical Dangers:
Chemical Dangers:
The substance will polymerize
due to heating or in the presence of a catalyst, if not inhibited.
On combustion, forms toxic gases.
Reacts with strong oxidants, acids and bases.
Occupational Exposure Limits:
TLV not established.
MAK: IIb (not established but data is available) (DFG 2006).
|
Routes of Exposure:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
4.4 mg/l x 4 h;
656 (females)-891 (males) mg/kg
Inhalation Risk:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis.
1.61 mm2/s (13 cP) at 20 C --> therefore lower viscosity at 40 C (Oct 2006).
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
