IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. The substance can be absorbed into the body by inhalation of its vapour
or aerosol, through the skin and by ingestion.
Physical dangers
The vapour is heavier than air and may travel along the ground; distant Inhalation risk
ignition possible. The vapour mixes well with air, explosive mixtures are No indication can be given about the rate in which a harmful concentration

Chemical dangers Effects of short-term exposure
Reacts violently with oxidants. Attacks many alkaline and earth alkaline The substance is irritating to the eyes, the skin and the respiratory tract.
