EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION

  • Local exhaust or breathing protection.
    Fresh air, rest.
  • SKIN



  • EYES

  • 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; if appropriate, moisten first to prevent dusting.
    Separated from bases, oxidants and reducing agents. Well closed.

    PHYSICAL STATE; APPEARANCE:
    COLOURLESS OR WHITE CRYSTALS.

    PHYSICAL DANGERS:
    Dust explosion possible if in powder or granular form, mixed with air.

    CHEMICAL DANGERS:
    Reacts with bases, oxidants and reducing agents.

    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 by dispersing.




    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    PHYSICAL
    PROPERTIES
    Boiling point: 351-352C
    Melting point: 63C
    Relative density (water = 1): 0.85
    Solubility in water: none
    Vapour pressure, Pa at 154C: 133
    Octanol/water partition coefficient as log Pow: 5.31
