|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive. Risk of fire and explosion on contact with acids or oxidants.||NO open flames, NO sparks and NO smoking. NO contact with acids. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.||Use water spray, alcohol-resistant foam, dry powder. NO carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.|
|AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!|
|SYMPTOMS||ACUTE HAZARDS||FIRST AID|
|Inhalation||Cough. Sore throat. Burning sensation. Shortness of breath. Laboured breathing. Nausea. Vomiting. Dizziness. Headache. Symptoms may be delayed.||Use closed system.||Fresh air, rest. Half-upright position. Refer immediately for medical attention.|
|Skin||MAY BE ABSORBED! Redness. Further see Inhalation.||Protective gloves. Protective clothing.||First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .|
|Eyes||Redness. Pain. Blurred vision.||Wear face shield 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||Sore throat. Further see Inhalation.||Do not eat, drink, or smoke during work.||Rinse mouth. Do NOT induce vomiting. Refer for medical attention .|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.||

|PHYSICAL & CHEMICAL INFORMATION|
Physical State; Appearance
|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|Occupational exposure limits|
TLV: 0.2 ppm as TWA; 0.4 ppm as STEL; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans).
MAK: skin absorption (H); carcinogen category: 2; germ cell mutagen group: 3B
|Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61°C.
Reacts violently with fire extinguishing agents such as carbon dioxide.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Data on similar substances suggest the possibility of environmental effects.
An added stabilizer or inhibitor can influence the toxicological properties of this substance; consult an expert.
Do NOT take working clothes home.
