CAS #: 5131-66-8
EC Number: 225-878-4

  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Above 63°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 63°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, foam, powder, carbon dioxide.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation   Use ventilation.  Fresh air, rest. 
Skin Redness. Pain.  Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles.  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. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
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. Then wash away with plenty of water.
