  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable.  Above 58°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 58°C use a closed system and ventilation.  Use AFFF, alcohol-resistant foam, dry powder, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Headache.  Use ventilation.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion   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. Remove all ignition sources. 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.
