Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaledIf breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
In case of skin contactWash off with soap and plenty of water. Consult a physician.
In case of eye contactRinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
If swallowedNever give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
4.2 Most important symptoms/effects, acute and delayedFollowing severe exposure to dust, symptoms of cyanide poisoning may develop (see ingestion). Ingestion causes anxiety, confusion, dizziness, sudden loss of consciousness, odor of bitter almonds on breath or in vomitus, rapid weak pulse, convulsions, and paralysis. Contact with eyes causes irritation. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessaryBasic Treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal ... . /Copper and related compounds/
5.Fire-fighting measures 5.1 Extinguishing media Suitable extinguishing mediaIf material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use foam, dry chemical or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock down vapors.
5.2 Specific hazards arising from the chemicalSpecial Hazards of Combustion Products: Toxic hydrogen cyanide gas may form in fires. (USCG, 1999)
5.3 Special protective actions for fire-fightersWear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures 6.1 Personal precautions, protective equipment and emergency proceduresUse personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.
6.2 Environmental precautionsPrevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.
6.3 Methods and materials for containment and cleaning upSTUDIES OF WASTEWATER TREATMENT AT 6 METAL ELECTROPLATING PLANTS REVEALED THAT A PH OF 9-10, A POLYMERIC FLOCCULANT, AND A CONVENTIONAL CLARIFIER-SLUDGE SYSTEM WERE THE MOST EFFECTIVE TREATMENTS. REACTION TIMES WERE GREATEST FOR THE OXIDATION OF NICKEL CYANIDE, FOLLOWED BY COPPER CYANIDE, & THEN ZINC CYANIDE.
7.Handling and storage 7.1 Precautions for safe handlingAvoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.
7.2 Conditions for safe storage, including any incompatibilities... SHOULD BE STORED IN COOL, WELL-VENTILATED PLACE, OUT OF DIRECT RAYS OF SUN, AWAY FROM ... FIRE HAZARD, & SHOULD BE PERIODICALLY INSPECTED & MONITORED. INCOMPATIBLE MATERIALS SHOULD BE ISOLATED ... /CYANIDES & COPPER CMPD/

Recommended Exposure Limit: 10 Hr Time-Weighted Avg: 1 mg/cu m. /Copper (dusts and mists)/
Biological limit valuesno data available
8.2 Appropriate engineering controlsHandle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
8.3 Individual protection measures, such as personal protective equipment (PPE) Eye/face protectionSafety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protectionWear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
Respiratory protectionWear dust mask when handling large quantities.

10.2 Chemical stabilityStable under recommended storage conditions.
10.3 Possibility of hazardous reactionsNot combustible.COPPER CYANIDE is decomposed by acids to give off hydrogen cyanide, a flammable poisonous gas. Tends to explosive instability. Capable of violent oxidation under certain condition: fusion with metal chlorates, perchlorates, nitrates or nitrites can cause explosions [Bretherick, 1979 p. 101]. Reacts with incandescence with magnesium [Mellor, 1940, Vol. 4, 271].
