International Chemical Safety Cards COPPER ICSC: 0240 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: RED POWDER, TURNS GREEN ON EXPOSURE TO MOIST AIR. PHYSICAL DANGERS: 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: 0.2 mg/m3 fume (ACGIH 1992-1993). TLV (as Cu, dusts & mists): 1 mg/m3 (ACGIH 1992-1993). OSHA PEL*: TWA 1 mg/m3 *Note: The PEL also applies to other copper compounds (as Cu) except NIOSH REL: TWA 1 mg/m3 *Note: The REL also applies to other copper compounds (as Cu) except Copper fume. NIOSH IDLH: 100 mg/m3 (as Cu) 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: Inhalation of fumes may cause metal fume fever. See Notes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. PHYSICAL PROPERTIES Boiling point: 2595°C Melting point: 1083°C Relative density (water = 1): 8.9 Solubility in water: none ENVIRONMENTAL DATA N O T E S The symptoms of metal fume fever do not become manifest until several hours.
