Combustible. Above 58°C explosive vapour/air mixtures may be formed.
NO open flames. NO contact with hot surfaces. Above 58°C use a closed system and ventilation.
Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
PREVENT GENERATION OF MISTS! STRICT HYGIENE!
Cough. Sore throat.
Use ventilation, local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
Wear safety goggles or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention .
CLASSIFICATION & LABELLING
Personal protection: chemical protection suit including self-contained breathing apparatus. Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible.
According to UN GHS Criteria
Transportation UN Classification
UN Hazard Class: 6.1; UN Pack Group: III
Separated from strong oxidants, strong bases, strong acids and food and feedstuffs.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH PUNGENT ODOUR.
Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible.
Chemical dangers Decomposes on burning. Decomposes on contact with hot surfaces. This produces toxic fumes. Reacts with strong oxidants, strong acids and strong bases.
