EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

  • INHALATION
    		• Blue lips or finger nails. Blue skin. Shortness of breath.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN

    		• Protective gloves.

  • EYES
    		• Pain.
    		Safety spectacles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Blue lips or fingernails. Blue skin.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: P2 filter respirator for harmful particles).
    		Separated from strong oxidants.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS CRYSTALS OR WHITE POWDER.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic and corrosive fumes of nitrogen oxides. Reacts with oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


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

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

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes and the respiratory tract. The substance may cause effects on the blood , resulting in formation of methaemoglobin.
