IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID The substance can be absorbed into the body by inhalation and
by ingestion.
Physical dangers
Inhalation risk
The vapour is heavier than air.
No indication can be given about the rate in which a harmful
concentration in the air is reached on evaporation of this
Occupational exposure limits
substance at 20/C.
TLV: 20 ppm as TWA; (ACGIH 2004).
MAK not established.
Effects of short-term exposure
If this liquid is swallowed, aspiration into the lungs may result in
chemical pneumonitis. Exposure at high levels could cause
lowering of consciousness.
Effects of long-term or repeated exposure
The liquid defats the skin.
