  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of fire and explosion if formulations contain flammable/explosive solvents.      Use water spray, foam, powder, carbon dioxide.   

 AVOID ALL CONTACT!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision.  Wear safety spectacles or eye protection in combination with breathing protection if powder.  Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Burning sensation in the throat and chest. Abdominal pain.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention .
