EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
  • Cough. Sore throat.
    Local exhaust.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • Redness.
    Protective gloves.
    Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
  • Redness. Pain.
    Face shield.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • Confusion. Convulsions. Weakness.
    Do not eat, drink, or smoke during work. Wash hands before eating.
    Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.
    Separated from acids, bases and oxidants. Dry. Keep in the dark. Well closed.

    PHYSICAL STATE; APPEARANCE:
    COLOURLESS OR WHITE DELIQUESCENT CRYSTALS.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes on heating and under influence of light producing toxic fumes of sulfur oxides, nitrogen oxides and cyanides. Reacts violently with acids, strong bases and strong oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.


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

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

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system , resulting in convulsions and confusion.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the blood, central nervous system and thyroid , resulting in anaemia, lesions of blood cells and emociation.
