IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. The substance can be absorbed into the body by inhalation.
Physical dangers Inhalation risk
The vapour is heavier than air and may travel along the ground; A harmful contamination of the air can be reached rather quickly
distant ignition possible. on evaporation of this substance at 20/C.
Chemical dangers Effects of short-term exposure
The substance decomposes on burning producing toxic gases The substance is irritating to the eyes and the respiratory tract.
