EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION

    		• Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.
    		Fresh air, rest.
  • SKIN

    		• Protective gloves.
    		Rinse and then wash skin with water and soap.
  • EYES

    		• Safety spectacles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION



    • SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting (extra personal protection: P1 filter respirator for inert particles).

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: ppm; 2 mg/m3 (as TWA) (ACGIH 1995-1996).
    OSHA PEL: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp)
    NIOSH REL: TWA 10 mg/m3 (total) TWA 5 mg/m3 (resp)
    NIOSH IDLH: No data


    		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 LONG-TERM OR REPEATED EXPOSURE:
     Lungs may be affected by repeated or prolonged exposure to dust particles. The substance may have effects on the lungs , resulting in fibrosis (kaolinosis) and impaired functions.
    PHYSICAL
    PROPERTIES
    Relative density (water = 1): 2.6

    DATA
    N O T E S
    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 indicated. Fitrol, Glomax, Kaophills-2 are trade names. Also consult ICSC # 0808.
