  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Highly flammable. Heating will cause rise in pressure with risk of bursting.  Vapour/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools.  Use carbon dioxide, dry powder.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use ventilation.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear safety spectacles.  Rinse with plenty of water (remove contact lenses if easily possible). 
Ingestion   Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Seek medical attention if you feel unwell. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. 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.
