TYPES OF HAZARD
|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE-FIGHTING|
|FIRE||Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire.||In case of fire in the surroundings, use appropriate extinguishing media.|
|EXPLOSION||Heating will cause rise in pressure with risk of bursting. Risk of fire and explosion. See Chemical Dangers.||Prevent build-up of electrostatic charges (e.g., by grounding).||In case of fire: keep drums, etc., cool by spraying with water.|
|EXPOSURE||PREVENT GENERATION OF MISTS! STRICT HYGIENE!|
|Inhalation||Dizziness. Drowsiness. Headache. Nausea. Weakness. Unconciousness. Death||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Artificial respiration may be needed. Refer immediately for medical attention.|
|Skin||Dry skin. Redness. Burning sensation.||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse and then wash skin with water and soap.|
|Eyes||Pain. Redness.||Wear safety spectacles 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.|
|Ingestion||Abdominal pain. Further see Inhalation.||Do not eat, drink, or smoke during work.||Rinse mouth. Do NOT induce vomiting. Refer for medical attention .|
|PACKAGING & LABELLING|
|Personal protection: self-contained breathing apparatus. Ventilation. 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 transport with food and feedstuffs.

Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR.
Occupational exposure limits
Routes of exposure
The substance can be absorbed into the body by inhalation, by ingestion and through the skin.
Effects of short-term exposure
Effects of long-term or repeated exposure
|PHYSICAL PROPERTIES||ENVIRONMENTAL DATA|
Boiling point: 40°C
Melting point: -95.1°C
Relative density (water = 1): 1.3
Solubility in water, g/100ml at 20°C: 1.3 (moderate)
Vapour pressure, kPa at 20°C: 47.4
Relative vapour density (air = 1): 2.9
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.9
Auto-ignition temperature: 605°C
Explosive limits, vol% in air: 12-25
Octanol/water partition coefficient as log Pow: 1.25
Viscosity: 0.15 mm²/s at 20°C
Addition of small amounts of a flammable substance or an increase in the oxygen content of the air strongly enhances combustibility.
Depending on the degree of exposure, periodic medical examination is suggested.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
