|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Extremely flammable.||NO open flames, NO sparks and NO smoking.||Use powder, AFFF, foam, carbon dioxide.|
|EXPLOSION||Vapour/air mixtures are explosive.||Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling.||In case of fire: keep drums, etc., cool by spraying with water.|
|EXPOSURE||PREVENT GENERATION OF MISTS!|
|Inhalation||Burning sensation. Cough. Dizziness. Laboured breathing. Nausea. Shortness of breath. Sore throat.||Use ventilation. Use local exhaust or breathing protection.||Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.|
|Skin||Redness. Pain.||Protective gloves.||Rinse skin with plenty of water or shower. Refer for medical attention .|
|Eyes||Redness. Pain.||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.|
|Ingestion||Abdominal pain. Burning sensation.||Do not eat, drink, or smoke during work.||Rinse mouth. Refer for medical attention .|
|PACKAGING & LABELLING|

|The substance is harmful to aquatic organisms.|
Usually contains inhibitors to prevent polymerization.
Data are insufficiently available on the effect of this substance on human health, therefore utmost care must be taken.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Check for peroxides prior to distillation; eliminate if found.
Vapours are uninhibited and may polymerize, blocking valves and vents.
