  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Above 56°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 56°C use a closed system and ventilation.  Use foam, dry powder, carbon dioxide.   

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Burning sensation. Cough. Chest tightness. Nausea. Vomiting.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Burning sensation. Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness. Pain. Watering of the eyes.  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   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: chemical protection suit including self-contained breathing apparatus. 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.
