EXPOSURE
PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF (PREGNANT) WOMEN!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION

  • Ventilation.
    Refer for medical attention.
  • SKIN

    PHYSICAL STATE; APPEARANCE:
    COLOURLESS FLAKES , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:


    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.


    ROUTES OF EXPOSURE:
    The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

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