COPPER ICSC: 0240
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
RED POWDER, TURNS GREEN ON EXPOSURE TO MOIST AIR.

CHEMICAL DANGERS:
Shock-sensitive compounds are formed with acetylenic compounds, ethylene oxides and azides. Reacts with strong oxidants like chlorates, bromates and iodates, causing explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: ppm; 0.2 mg/m^3 fume (ACGIH 1992-1993). TLV (as Cu, dusts & mists): ppm; 1 mg/m3 (ACGIH 1992-1993).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
Inhalation of fume may cause metal fever (see Notes).

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization.
PHYSICAL PROPERTIES
Boiling point: 2595C
Melting point: 1083C
Relative density (water = 1): 8.9
Solubility in water: none
ENVIRONMENTAL DATA

NOTES
The symptoms of metal fume fever do not become manifest until several hours.
