  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Above 46°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 46°C use a closed system, ventilation and explosion-proof electrical equipment.  Use powder, AFFF, foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT GENERATION OF MISTS! STRICT HYGIENE!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. 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 Sore throat. Burning sensation.  Do not eat, drink, or smoke during work.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention .
