IMPORTANT DATA
Physical State; Appearance Routes of exposure
GAS OR COLOURLESS LIQUID, WITH PUNGENT ODOUR. The substance can be absorbed into the body by inhalation and
by ingestion.
Physical dangers
Inhalation risk
The vapour is heavier than air and may travel along the ground;
distant ignition possible. A harmful contamination of the air can be reached very quickly
on evaporation of this substance at 20/C.
Chemical dangers
Effects of short-term exposure
The substance can form explosive peroxides in contact with air.
The substance may polymerize under the influence of acid(s) The substance is mildly irritating to the eyes, the skin and the

ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
The occupational exposure limit value should not be exceeded during any part of the working exposure.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Rinse contaminated clothes (fire hazard) with plenty of water.
