TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable.  NO open flames, NO sparks and NO smoking. NO contact with strong oxidizing agents.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Above 44°C explosive vapour/air mixtures may be formed.  Above 44°C use a closed system, ventilation and explosion-proof electrical equipment.   
 
EXPOSURE      
Inhalation   Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. 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 Cough. Nausea. Sore throat.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Remove all ignition sources. Personal protection: face shield. 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.
