Flammable. Above 25°C explosive vapour/air mixtures may be formed. Risk of fire and explosion on contact with strong oxidizing agents.
NO open flames, NO sparks and NO smoking. NO contact with strong oxidizing agents. Above 25°C use a closed system, ventilation and explosion-proof electrical equipment.
Use AFFF, alcohol-resistant foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
PREVENT GENERATION OF MISTS!
Cough. Nausea. Sore throat.
Fresh air, rest.
Rinse and then wash skin with water and soap.
Wear safety goggles.
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. Rest.
CLASSIFICATION & LABELLING
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.
According to UN GHS Criteria
Transportation UN Classification
UN Hazard Class: 3; UN Pack Group: III
Fireproof. Separated from strong oxidants. Cool. Well closed.
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 Reacts violently with strong oxidants. This generates fire and explosion hazard. Attacks many plastics and resins.

Molecular mass: 118.13
Boiling point: 126°C Melting point: -43°C Relative density (water = 1): 0.98 Solubility in water: none Vapour pressure, kPa at 20°C: 1.1 Relative vapour density (air = 1): 4.07 Flash point: 25°C c.c. Auto-ignition temperature: 445°C Explosive limits, vol% in air: 1.4-11.0
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation.
Effects of short-term exposure The substance is irritating to the eyes and respiratory tract.
Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.
Effects of long-term or repeated exposure
OCCUPATIONAL EXPOSURE LIMITS
Environmental effects from the substance have not been investigated adequately.
