EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION

    		• Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• Dry skin.

    		Rinse and then wash skin with water and soap.
  • EYES
    		• Redness. Pain.
    		Safety spectacles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION

    		• Do not eat, drink, or smoke during work.

    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers. Wash away remainder with plenty of water (extra personal protection: P2 filter respirator for harmful particles).

    PHYSICAL STATE; APPEARANCE:
     ODOURLESS, WHITE, VERY FINE CRYSTALLINE POWDER OR GREEN TO GREY TO WHITE SOLID IN VARIOUS FORMS.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: ppm; 2 mg/m3 as TWA (ACGIH 1993-1994).
    OSHA PEL: TWA 20 mppcf
    NIOSH REL: TWA 2 mg/m3 (resp)
    NIOSH IDLH: 1000 mg/m3


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation.

    INHALATION RISK:
     Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

    EFFECTS OF SHORT-TERM EXPOSURE:

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the lungs , resulting in talc pneumoconiosis.
