|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Highly flammable. Vapour/air mixtures are explosive.||NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.||Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.|
|PREVENT GENERATION OF MISTS!|
|Inhalation||Cough. Dizziness. Headache. Nausea. Sore throat. Unconsciousness.||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 .|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. 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.||
According to UN GHS Criteria
|Fireproof. See Chemical Dangers. Store only if stabilized.|

|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.
