TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible.    In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
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   Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion      

SPILLAGE DISPOSAL
PACKAGING & 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.

IMPORTANT DATA
Physical State; Appearance
WHITE POWDER. 

Physical dangers
No data. 

Chemical dangers
No data. 

Occupational exposure limits
TLV (respirable fraction): 2mg/m³ as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol. 

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation of dust particles may cause effects on the lungs. The substance may have effects on the lungs. This may result in fibrosis (kaolinosis) and impaired functions. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Relative density (water = 1): 2.6
Solubility in water: none 
 

NOTES
This card applies to kaolin containing <1% crystalline silica.
If kaolin contains more than 1% crystalline silica, fusion temperature 1785°C.
Depending on the degree of exposure, periodic medical examination is suggested.
Fitrol, Glomax, Kaophills-2 are trade names.
