EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!

  • INHALATION
    		• Cough. Sore throat. Metal fume fever. Metallic taste. See Notes.
    		Local exhaust or breathing protection.
    		Fresh air, rest.
  • SKIN
    		• Dry skin.

    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
    		• Redness. Pain.
    		Safety goggles, or eye protection in combination with breathing protection.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Abdominal pain. Diarrhoea. Nausea. Vomiting. Metallic taste.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Give plenty of 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).

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV (as Cu, dust and mists): 1 mg/m3; (as Cu, fume: 0.2 mg/m3) (ACGIH 1996).
    MAK as Cu: ppm; mg/m3 1 (1996).


    		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 harmful concentration of airborne particles can, however, be reached quickly when dispersed.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes and the respiratory tract. Inhalation of fume may cause metal fever. The substance may cause effects on the kidneys and liver after ingestion. The effects may be delayed.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact with skin may cause dermatitis.

    ENVIRONMENTAL
    DATA
    N O T E S
    Headache, cough, sweating, nausea and fever may be caused by freshly formed fumes or dust of copper oxide. The symptoms of metal fume fever do not become manifest until 4-12 hours after exposure. C.I. 77402, Copox, Copper Nordox, Copper Sardex, Perenox, Yellow Cuprocide are trade names.
