Specific Hazards Arising from the Material: May release metal oxide fumes if involved in a fire.

Special Protective Equipment and Precautions for Firefighters: Wear full face, self-contained breathing apparatus and full protective clothing.

6   ACCIDENTAL RELEASE MEASURES

Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Isolate spill area and provide ventilation. Avoid breathing dust or fume. Avoid contact with skin and eyes. Eliminate all sources of ignition.

Methods and Materials for Containment and Cleaning Up: Avoid raising dust. Cleanup spills with a vacuum system utilizing a high efficiency particulate air (HEPA) filtration system and place in a properly labeled closed container for further handling and disposal.

Environmental Precautions: Do not allow to enter drains or to be released to the environment.

7   HANDLING AND STORAGE

Precautions for Safe Handling: Handle in an enclosed, controlled process. Protect from moisture. Avoid creating dust. Avoid breathing dust or fumes. Provide adequate ventilation if dusts are created. Avoid exposure to high temperature. Avoid contact with skin and eyes. Wash thoroughly before eating or smoking. See section 8 for information on personal protection equipment.

Conditions for Safe Storage: Store in a cool, dry area. Store material tightly sealed in properly labeled containers. Protect from moisture. See section 10 for more information on incompatible materials.

8  EXPOSURE CONTROLS AND PERSONAL PROTECTION

Exposure Limits:                                OSHA/PEL:                              ACGIH/TLV:

Copper Tungstate                                  No exposure limit established     No exposure limit established

Copper dusts and mists (as Cu)              1 mg/m³                                  1 mg/m³

Tungsten insoluble compounds (as W)     No exposure limit established     10 mg/m³

Appropriate Engineering Controls: Handle in a controlled, enclosed environment. Ensure adequate ventilation to maintain exposures below occupational limits. Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air.

Individual Protection Measures, Such as Personal Protective Equipment:

   Respiratory Protection: Use suitable respirator when dusts or fumes are present.

   Eye Protection: Safety glasses

   Skin Protection: Impermeable gloves, protective work clothing.

11   TOXICOLOGICAL INFORMATION

Likely Routes of Exposure: Inhalation, skin and eyes.

Symptoms of Exposure: May be irritating to eyes, skin and respiratory system. May cause gastrointestinal irritation and/or flu-like symptoms.

Acute and Chronic Effects:

Copper Compounds: In general the soluble ionized salts of copper are much more toxic than the insoluble or slightly dissociated compounds. The lethal dose of any copper salt varies widely (from less than 1 g to several ounces in adults). Systemic toxic effects of copper include widespread capillary damage, kidney and liver injury, and central nervous excitation followed by depression. Jaundice and pain over the liver have been reported in acute human poisonings. Copper is mainly absorbed through the gastrointestinal tract. All other intakes of copper (inhalation and dermal) are insignificant in comparison to the oral route.

Tungsten Compounds: Respiratory effects were reported in workers who were occupationally exposed to airborne dusts containing tungsten trioxide, tungsten dioxide, metallic tungsten, and tungsten carbide in areas where high tensile strength tungsten (hard metal) was prepared. It is generally believed that the health effects observed in hard metal workers are the result of exposure to cobalt or other metals, not tungsten. In a study with rats, it was demonstrated that intratracheally-instilled tungsten carbide and cobalt in combination, but not alone, induced interstitial pulmonary fibrosis. Acute oral exposure to tungsten does not appear to be a particular toxicity concern, based on acute oral LD50 values ranging from 240 to 11,300 mg/kg/day for several soluble tungsten compounds. No human data were located in which systemic toxicity could be associated with oral exposure to tungsten or tungsten compounds. Signs of slight conjunctival irritation were noted in rabbits following single ocular instillation of 100 mg of sodium tungstate dihydrate powder or tungsten metal powder.
