3 COMPOSITION/INFORMATION ON INGREDIENTS
Ingredient: Cobalt
CAS#: 7440-48-4
%: >99
EC#: 231-158-0
4 FIRST AID MEASURES
General Measures: Remove patient from area of exposure.
INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek medical attention.
INGESTION: Quickly wipe material from mouth and rinse with water. Do not induce vomiting. Seek medical attention.
SKIN: Remove contaminated clothing, brush material off skin, wash affected area with soap and water. Seek medical attention if symptoms persist.
EYES: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persist.
Most Important Symptoms/Effects, Acute and Delayed: May cause irritation. May cause an allergic reaction. See section 11 for more information.
Indication of Immediate Medical Attention and Special Treatment: No other relevant information available.
5 FIREFIGHTING MEASURES
Extinguishing Media: Use Class D or other metal extinguishing agent.
Unsuitable Extinguishing Media: No information available.
Specific Hazards Arising from the Material: Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source, is a potential dust explosion hazard. May emit fumes of cobalt oxide under fire conditions.
Special Protective Equipment and Precautions for Firefighters: Full face, self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.
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 creating dust. Use only non-sparking tools and natural bristle brushes. Scoop or vacuum up spill using a vacuum rated for combustible metal dusts equipped with a HEPA filter. Place in properly labeled closed containers.
Environmental Precautions: Do not allow to enter drains or to be released to the environment.
7 HANDLING AND STORAGE
Precautions for Safe Handling: Transfer material in closed systems or within a completely hooded containment with local exhaust ventilation. Prevent spillage. Protect from sources of ignition. Avoid breathing dusts. Avoid contact with skin and eyes. Prevent contact with clothing. Wear gloves when handling this product. Wash thoroughly before eating or smoking. See section 8 for information on personal protection equipment.
Conditions for Safe Storage, Including Any Incompatibilities: Store in a sealed container. Store in a cool, dry area. Storage containers should be labeled to indicate their contents. Protect from acids. Store away from heat and ignition sources. See section 10 for more information on incompatible materials.
8 EXPOSURE CONTROLS AND PERSONAL PROTECTION
Exposure Limits: Cobalt
OSHA/PEL: 0.1 mg/m3
ACGIH/TLV: 0.02 mg/m3
Appropriate Engineering Controls: When working with finely divided powders, handle in a controlled, enclosed environment, preferably under argon. 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: Wear approved respirator.
Eye Protection: Safety glasses or goggles
Skin Protection: Wear impermeable gloves, protective work clothing.

11 TOXICOLOGICAL INFORMATION
Likely Routes of Exposure: Inhalation, skin and eyes.
Symptoms of Exposure: May cause irritation. May cause an allergic reaction in sensitized individuals.
Acute and Chronic Effects: 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.
