Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. Heating will cause rise in pressure with risk of bursting. Vapour/air mixtures are explosive.
NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting.
Use powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
Cough. Drowsiness. Dizziness. Headache. Nausea.
Use ventilation, local exhaust or breathing protection.
Fresh air, rest.
Rinse and then wash skin with water and soap.
Wear safety spectacles.
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.
Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .
CLASSIFICATION & LABELLING
Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.
According to UN GHS Criteria
Transportation UN Classification
UN Hazard Class: 3; UN Pack Group: II
Fireproof. Cool. Keep in a well-ventilated room. Separated from strong oxidants, strong bases and strong acids.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR.
Physical dangers The vapour is heavier than air and may travel along the ground; distant ignition possible.
Chemical dangers On combustion, forms corrosive fumes including hydrogen sulfide and sulfur oxides. Reacts violently with oxidants, reducing agents, strong acids and strong bases.
