|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Highly flammable.||NO open flames, NO sparks and NO smoking.||Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide.|
|EXPLOSION||Vapour/air mixtures are explosive.||Closed system, ventilation, explosion-proof electrical equipment and lighting. 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||Cough. Dizziness. Headache. Nausea. Sore throat. Unconciousness.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||Dry skin. Redness. Pain.||Protective gloves.||Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .|
|Eyes||Redness. Pain.||Wear safety spectacles.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||See Inhalation.||Do not eat, drink, or smoke during work.||Rinse mouth. Refer for medical attention .|

p-Cresol or hydroquinone are commonly used stabilizers.
Use of alcoholic beverages enhances the harmful effect.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
The odour warning when the exposure limit value is exceeded is insufficient.
Check for peroxides prior to distillation; eliminate if found.
