  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.    NO open flames.    Use water spray, powder, foam, carbon dioxide.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin No acute symptoms expected.  Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes Redness.  Wear safety spectacles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion No acute symptoms expected.  Do not eat, drink, or smoke during work.  Rinse mouth. Seek medical attention if you feel unwell. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
May cause mechanical irritation to the eyes and respiratory tract. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered. 

Effects of long-term or repeated exposure
The substance may have effects on the blood. This may result in anaemia. 


Occupational exposure limits
 

ENVIRONMENT
 

NOTES
Health effects of exposure to the substance have not been investigated adequately.
