|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Extremely flammable.||NO open flames, NO sparks and NO smoking. NO contact with hot surfaces.||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. Use non-sparking handtools.||In case of fire: keep drums, etc., cool by spraying with water.|
|EXPOSURE||AVOID ALL CONTACT!|
|Inhalation||Cough.||Use ventilation. Use local exhaust or breathing protection.||Fresh air, rest. Refer for medical attention.|
|Skin||Redness. Pain.||Protective gloves.||Remove contaminated clothes. Rinse and then wash skin with water and soap. 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||Diarrhoea. Dizziness. Nausea. Vomiting.||Do not eat, drink, or smoke during work.||Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention .|
|PACKAGING & LABELLING|
|Remove all ignition sources. Evacuate danger area! Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. 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 absorb in saw-dust or other combustible absorbents. Remove vapour with fine water spray.||
Put breakable packaging into closed unbreakable container.
