  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT DISPERSION OF DUST! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Confusion. Drowsiness. Nausea. Unconsciousness.  Use local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer immediately for medical attention. 
Skin Redness.  Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear safety spectacles or eye protection in combination with breathing protection if powder.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour or dust and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. This may result in disorientation, lowering of blood pressure and lowering of consciousness. Exposure at high levels could cause cardiac dysrhythmia and unconsciousness or death. 

Inhalation risk
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. 

Effects of long-term or repeated exposure
The substance may have effects on the liver. This may result in addiction, behavioural effects and liver impairment. This substance is probably carcinogenic to humans. May cause heritable genetic damage to human germ cells. 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
This substance may be hazardous to the environment. Special attention should be given to aquatic organisms. 

NOTES
Use of alcoholic beverages enhances the harmful effect.
Depending on the degree of exposure, periodic medical examination is suggested.
