SECTION 2 – COMPOSITION / INFORMATION ON INGREDIENTS
      
COMPONENT CAS # RANGE % BY WT
Copper 7440-50-8 84-96
Tin 7440-31-5 4-16

SECTION 3 – HAZARDS IDENTIFICATION
EYE CONTACT: No significant irritation expected other than possible mechanical irritation.
SKIN CONTACT: No significant irritation expected other than possible mechanical irritation.
INHALATION: No significant irritation expected other than possible mechanical irritation.  Dust or fume from metallizing, welding or similar processes can cause respiratory irritation and/or metal fume fever (nausea, vomiting, fever, diarrhea).
INGESTION: No significant health hazards identified.

SECTION 4 – FIRST AID MEASURES
EYES: Flush eyes with plenty of water, lifting the upper and lower eyelids occasionally. Get medical attention if irritation develops.
SKIN: Wash the skin using soap or a mild detergent and warm water.
INHALATION: Move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Get immediate medical attention. Fume from metallizing, welding or similar processes can cause respiratory irritation and/or metal fume fever (respiratory irritation, chills, nausea).
INGESTION: If person is conscious, rinse mouth and give large quantities of water to drink. Get medical attention.

SECTION 5 – FIRE FIGHTING MEASURES
EXTINGUSHING MEDIA: Graphite, dolomite or sodium chloride.  Do NOT use water.
UNUSUAL FIRE AND  EXPLOSION HAZARDS: Copper powder with particles sizes 50 µm size range are classified as weakly explosive by the U.S. Bureau of Mines Report RI-6516.  When present as a dust cloud, will NOT explode readily in air.  Not easily ignited by sparks.
FIRE FIGHTING EQUIPMENT: Wear full bunker gear including a positive pressure self-contained breathing apparatus.
PRECAUTIONS: Keep away from ignition sources (e.g., heat and open flames).  None required.  Keep container closed.
HAZARDOUS DECOMPOSITION: Upon heating in the presence of air, material decomposes to sulfur dioxide, cuprous oxide and copper sulfate.

SECTION 6 – ACCIDENTAL RELEASE MEASURES
1. Restrict the area to those persons wearing respiratory protection.  Do not allow unprotected people into the area until cleanup has been completed.
2. Ventilate the area thoroughly.
3. Collect the powder in a manner that minimizes further dust generation (i.e., use wet or HEPA vacuum methods).
4. Keep out of sewers and waterways.
5. Recycle or dispose of as a waste (see Section 13).

SECTION 7 – HANDLING AND STORAGE
1. Avoid dust generation.
2. Wash thoroughly after handling.
3. Avoid dust generation from dried paste.
4. Store powder in a dry area, -18˚ to 38˚C.

SECTION 8 – EXPOSURE CONTROLS / PERSONAL PROTECTION
VENTILATION REQUIREMENTS: Keep dust and fume levels below occupational exposure limits.  Local exhaust ventilation may be necessary for some operations.
PERSONAL PROTECTIVE EQUIPMENT
EYES: Wear dust-proof safety goggles.  Contact lenses are not recommended.
SKIN: None required; however, use of protective gloves and clothing is good industrial practice.  The use of impervious gloves or barrier cream to protect skin is recommended.
INHALATION: Do not breathe dust or fume.  Use with adequate ventilation. If ventilation is inadequate, use NIOSH/MSHA approved respirator.

SECTION 9 – CHEMICAL AND PHYSICAL PROPERTIES
APPEARANCE AND ODOR: Dull grayish-orange; odorless
FLASH POINT: Above 700˚C
FLAMMABILITY: Non-flammable
AUTOIGNITION TEMPERATURE: Not determined
pH: Not applicable
VAPOR PRESSURE: 1 mm Hg @ 1628˚C
VAPOR DENSITY: Not determined
MELTING POINT: About 1010˚C
BOILING POINT: Not determined
SOLUBILITY IN WATER: Not soluble
SOLUBILITY IN FAT: Not determined
OCTANOL/WATER PARTITION
COEFFICIENT: Not determined 
RELATIVE DENSITY (WATER=1): 3.1 - 5.5
VISCOSITY: Not applicable

SECTION 10 – STABILITY AND REACTIVITY
STABILITY: Stable to ignition temperature of 700˚C.
INCOMPATIBLE MATERIALS: Copper is explosively incompatible with sodium azide.  Copper dusts may react with acetylene gas to form copper acetylides, which are sensitive to shock.  Copper mists may react with magnesium to form flammable hydrogen gas.  Tin reacts with concentrated acids.  Contact with chlorine may result in ignition.  A vigorous reaction and incandescence is observed with sulfur.  Fires and explosions can result when tin contacts turpentine.
HAZARDOUS DECOMPOSITION: None identified.
HAZARDOUS POLYMERIZATION: Will not occur.

SECTION 11 – TOXICOLOGICAL INFORMATION
Copper is an essential element of mammalian metabolism.  Copper metal has little or no serious toxicity.  The most common adverse effect associated with copper is the acute inhalation of copper fume during refining or welding.  Inhalation of copper fume or dust may result in metal fume fever, which is characterized by upper respiratory irritation, chills, metallic or sweet taste, nausea, and aching muscles.  Attacks usually begin after 4-8 hours of exposure and last only 24-48 hours. Inhalation of fumes has been reported to sometimes cause discoloration of the skin and hair.  Nausea and vomiting may result if large amounts of copper metal are ingested.  This is probably due to the conversion of the swallowed metal copper to its irritating salts.  It is unlikely that poisoning by ingestion in industry would progress to a serious point because small amounts induce vomiting, emptying the stomach of copper salts.  High airborne concentrations of copper metal would be expected to cause mechanical irritation of the eyes and respiratory tract.  Metallic copper may cause keratinization of the hands and soles of the feet, but it is not commonly associated with industrial dermatitis.

Metallic tin is relatively non-toxic.  Exposure to dust or fumes of inorganic tin salts is known to cause benign inflammation of the lung tissue (stanosis), a condition in which there is no distinctive fibrosis, no evidence of disability, and no special complicating factors.  No component of this product present at levels greater than 0.1% is identified as a carcinogen by the U.S. National Toxicology Program, the U.S. Occupational Safety and Health Act or the International Agency for Research on Cancer (IARC).

SECTION 12 – ECOLOGICAL INFORMATION
