TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Extremely flammable.  NO open flames, NO sparks and NO smoking.  Use powder, foam, carbon dioxide. 
EXPLOSION Vapour/air mixtures are explosive.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation   Use ventilation.  Fresh air, rest. 
Skin Dry skin. Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety spectacles.  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.  Rinse mouth. Do NOT induce vomiting. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Evacuate danger area! Ventilation. 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. Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance.
