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




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 if dusts are present.

Methods and Materials for Containment and Cleaning Up: Avoid dust formation. Sweep or scoop up. Place in a properly labeled container for further handling and disposal.

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




Precautions for Safe Handling: Avoid creating dust. Avoid breathing dust or fumes. Provide adequate ventilation if dusts are created. 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. See section 10 for more information on incompatible materials.




Exposure Limits:    OSHA/PEL:                                             ACGIH/TLV:

Nickel                       1 mg/m3                                                 1.5 mg/m3

Chromium                1 mg/m3                                                  0.5 mg/m3

Iron (III) Oxide         10 mg/m3 (fume)                                     5 mg/m3 (respirable)

Molybdenum             15 mg/m3 (insol. compounds, total dust)    10 mg/m3 (insol. compounds, inhalable)

Niobium                    No exposure limit established                    No exposure limit established

Cobalt                      0.1 mg/m3                                              0.02 mg/m3

Engineering Controls: 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 dust or fumes are present.

   Eye Protection: Safety glasses

   Skin Protection: Impermeable gloves, protective work clothing as necessary.

Likely Routes of Exposure: Inhalation, skin, eyes.

Symptoms of Exposure: Fines/dusts may irritate lungs, eyes or abraded skin. Inhalation of metal oxide fumes due to heating beyond the boiling point in an oxidizing atmosphere, such as when smelting or welding, may cause substernal chest pain, cough, dyspnea and flu-like symptoms. The respiratory symptoms generally disappear in the exposed individual within 1-4 days.

Acute and Chronic Effects:  No adverse effects are expected from normal handling of this material in its solid form.

Nickel:  The most common harmful health effect of metallic nickel in humans is an allergic skin reaction in those who are sensitive to nickel. Although nickel compounds are known human carcinogens, the evidence suggests that the relatively insoluble metallic nickel is less likely to present a carcinogenic hazard than are the nickel compounds that tend to release proportionately more nickel ion.

Chromium:  Although much is known about the health effects of chromium compounds, the health effects of chromium metal, Cr(0), is not well studied. Due to insolubility most elements in their metallic state are not considered to be serious health hazards.

Iron:  If inhaled, iron is a local irritant to the lung and gastrointestinal tract. Inhalation of large amounts may cause iron pneumoconiosis. Chronic inhalation of finely divided powder may cause chronic iron poisoning and pathological deposition of iron in the body tissue. Ingestion may cause vomiting, diarrhea, pink urine, black stool, and liver damage.

Molybdenum:  When rats inhaled dusts of metallic molybdenum for 1 hour at 25 to 30 g/cu m … there were no changes in the condition of the animals observed in the 4 weeks following exposure.

Tungsten:  No ill effects were observed in patients given 25-80 g powdered tungsten metal by mouth as substitute for barium in radiological examinations. Long industrial experience has indicated no pneumoconiosis to develop among workers exposed solely to tungsten. Powdered tungsten may cause mechanical skin and/or eye irritation.

Niobium:  The biocompatibility of niobium metal is similar to that of tantalum, which is generally considered to be physiologically inert.

Cobalt:  Acute exposure to cobalt metal dusts or fumes is characterized by irritation to the eyes, and to a lesser extent, irritation to the skin. Chronic exposure to cobalt metal dust or fumes may cause respiratory and dermatologic signs and symptoms. Chronic exposure to cobalt by inhalation in humans results in effects on the respiratory system, such as respiratory irritation, wheezing, asthma, decreased lung function, pneumonia, and fibrosis.
