  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Extremely flammable.  Vapour/air mixtures are explosive.  NO open flames, NO sparks and NO smoking.    Use foam, alcohol-resistant foam, dry powder, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Dizziness. Drowsiness. Weakness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Dry skin.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   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. Do NOT induce vomiting. 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. 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. Do NOT wash away into sewer. Do NOT let this chemical enter the environment.
