  • CPC
  • CORROSIVE
NFPA 704: data unavailable
General Description
A yellowish-brown powder (the anhydrous form) or a green crystalline solid (the dihydrate). Noncombustible but hydrogen chloride gas may form when heated in a fire. Corrosive to aluminum. Used to manufacture other chemicals, in dyeing, in printing, in fungicides, as a wood preservative.

Hazards

Reactivity Alerts
none
Air & Water Reactions
The anhydrous form is hygroscopic, forming the dihydrate. The dihydrate is deliquescent in moist air, efflorescent in dry air. Both are water soluble. May corrode metals in the presence of moisture; the reaction is not hazardous [USCG, 1999].
Fire Hazard
Special Hazards of Combustion Products: Irritating hydrogen chloride gas may form in fire. (USCG, 1999)
Health Hazard
Inhalation causes coughing and sneezing. Ingestion causes pain and vomiting. Contact with solutions irritates eyes; contact with solid causes severe eye surface injury and skin irritation. (USCG, 1999)
Reactivity Profile
COPPER CHLORIDE can serve as a weak oxidizing agent. May catalyze organic reactions. Solutions are acidic (they contain moderate concentrations of hydrogen ions and have pH's of less than 7.0). They react as acids to neutralize bases. These neutralizations generate heat, but far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid.
Belongs to the Following Reactive Group(s)

Response Recommendations

Firefighting
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) (AAR, 2003)
Non-Fire Response
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Adjust pH to neutral (pH=7). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. (AAR, 2003)
Protective Clothing
Bu. Mines approved respirator; rubber gloves; safety goggles (USCG, 1999)
First Aid
INHALATION: move to fresh air.

INGESTION: give large amounts of water; induce vomiting; get medical attention.

EYES: flush with water for 15 min.; consult a doctor if injury was caused by solid.

SKIN: flush with water. (USCG, 1999)
