EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

  • INHALATION

    		• Local exhaust or breathing protection.
    		Fresh air, rest.
  • SKIN
    		• Redness.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • 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.
    		Rinse mouth. Rest.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING

    PHYSICAL STATE; APPEARANCE:
     WHITE TO GREY CRYSTALS.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating, on burning and on contact with strong acids producing toxic fumes including nitrogen oxides and sulfur oxides.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


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

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

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes and the skin.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact may cause skin sensitization.
    PHYSICAL
    PROPERTIES
    Melting point (decomposes): 288░C
    Relative density (water = 1): 1.5
