  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.  Above 98°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 98°C use a closed system, ventilation and explosion-proof electrical equipment.  Use foam, carbon dioxide, powder.   

   
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Dizziness. Headache. Nausea.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Severe deep burns. 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 Nausea. Vomiting. Dizziness. Drowsiness. Headache. Weakness.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. 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. 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.
