|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Highly flammable. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive.||NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Use non-sparking handtools.||Use powder, water spray, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.|
|STRICT HYGIENE! IN ALL CASES CONSULT A DOCTOR!|
|SYMPTOMS||ACUTE HAZARDS||FIRST AID|
|Inhalation||Cough. Sore throat. Headache. Dizziness. Drowsiness. Laboured breathing. Heart palpitations. Unconsciousness.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Refer immediately for medical attention.|
|Skin||MAY BE ABSORBED! Redness. Pain. Burning sensation. See Inhalation.||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer immediately for medical attention.|
|Eyes||Redness. Pain. Corneal damage.||Wear safety goggles, face shield or eye protection in combination with breathing protection.||Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.|
|Ingestion||See Inhalation.||Do not eat, drink, or smoke during work.||Rinse mouth. Do NOT induce vomiting. Refer immediately 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 sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.||
