     Section 3 - Hazards Identification



EMERGENCY OVERVIEW

Appearance: red. Moisture sensitive. Warning! Inhalation of fumes may cause

metal-fume fever. May cause eye and skin irritation. Avoid breathing dust. May

cause respiratory and digestive tract irritation.

Target Organs: Kidneys, liver.





Potential Health Effects

Eye: Dust may cause mechanical irritation. Causes eye irritation.

Skin: May cause skin irritation. May cause skin discoloration.

Ingestion: Causes gastrointestinal irritation with nausea, vomiting and

diarrhea. May cause liver and kidney damage.

Inhalation: Dust is irritating to the respiratory tract. Inhalation of fumes may

cause metal fume fever, which is characterized by flu-like symptoms with

metallic taste, fever, chills, cough, weakness, chest pain, muscle pain and

increased white blood cell count.

Chronic: Prolonged or repeated skin contact may cause dermatitis. May cause

liver and kidney damage.



     Section 4 - First Aid Measures



Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally

lifting the upper and lower eyelids. Get medical aid.

Skin: Flush skin with plenty of soap and water for at least 15 minutes while

removing contaminated clothing and shoes. Get medical aid if irritation develops

or persists.

Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water.

Never give anything by mouth to an unconscious person. Get medical aid.

Inhalation: Remove from exposure to fresh air immediately. If not breathing,

give artificial respiration. If breathing is difficult, give oxygen. Get medical

aid.

Notes to Physician: Individuals with Wilson's disease are more susceptible to

chronic copper poisoning.



     Section 5 - Fire Fighting Measures



General Information: As in any fire, wear a self-contained breathing apparatus

in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective

gear. This material in sufficient quantity and reduced particle size is capable

of creating a dust explosion.

Extinguishing Media: Use extinguishing media most appropriate for the

surrounding fire.

     Section 6 - Accidental Release Measures



General Information: Use proper personal protective equipment as indicated in

Section 8.

Spills/Leaks: Sweep up, then place into a suitable container for disposal. Avoid

generating dusty conditions.



     Section 7 - Handling and Storage



Handling: Wash thoroughly after handling. Use only in a well-ventilated area.

Minimize dust generation and accumulation. Avoid contact with eyes, skin, and

clothing. Avoid ingestion and inhalation.

Storage: Store in a tightly closed container. Store in a cool, dry,

well-ventilated area away from incompatible substances.



     Section 8 - Exposure Controls, Personal Protection



Engineering Controls: Use adequate general or local exhaust ventilation to keep

airborne concentrations below the permissible exposure limits.

Personal Protective Equipment

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as

described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or

European Standard EN166.

Skin: Wear appropriate protective gloves to prevent skin exposure.

Clothing: Wear appropriate protective clothing to minimize contact with skin.

Respirators: Follow the OSHA respirator regulations found in 29 CFR 1910.134 or

European Standard EN 149. Always use a NIOSH or European Standard EN 149

approved respirator when necessary.

     Section 10 - Stability and Reactivity



Chemical Stability: Stable at room temperature in closed containers under normal

storage and handling conditions. Exposure to moist air results in the formation

of a green base carbonate coating.

Conditions to Avoid: Dust generation, moisture, exposure to air.

Incompatibilities with Other Materials: Liquid copper explodes on contact with

water. Reacts violently with ammonium nitrate, bromates, iodates, chlorates,

ethylene oxide, hydrazoic acid, potassium oxide, dimethyl sulfoxide +

trichloroacetic acid, hydrogen peroxide, sodium peroxide, sodium azide, sulfuric

acid, hydrogen sulfide + air, and lead azide. Ignites on contact with chlorine,

fluorine (above 121C), chlorine trifluoride, and hydrazinium nitrate (above

70C). Incompatible with 1-bromo-2-propyne, potassium dioxide, and actylenic

compounds.

Hazardous Decomposition Products: Copper fumes.

Hazardous Polymerization: Has not been reported
