  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible.        In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation   Avoid inhalation of dust and mist. Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse and then wash skin with water and soap. 
Eyes Redness.  Wear safety spectacles.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). 
Ingestion      

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.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
Exposure mainly occurs via inhalation. 

Effects of short-term exposure
May cause mechanical irritation. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Lungs may be affected by repeated or prolongated exposure to dust particles. This may result in fibrosis (kaolinosis).

MAK: carcinogen category: 3B 

ENVIRONMENT
 

NOTES
This card applies to kaolin containing <1% crystalline silica.
Depending on the degree of exposure, periodic medical examination is suggested.
If kaolin contains more than 1% crystalline silica then see also ICSC0808 Quartz.
