Composition / Information on Ingredients

Component: Cobalt Carbonate
CAS Number: 513-79-1
Concentration: Greater than 98%
Impurities: Trace amounts of other cobalt compounds, such as cobalt oxide or hydroxide

First Aid Measures

Inhalation: Move to fresh air, seek medical attention if breathing gets difficult or symptoms persist.
Skin Contact: Remove contaminated clothing, wash thoroughly with soap and water, watch for skin irritation or rash, consult a doctor if symptoms worsen.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, keep eyelids open, get medical help if irritation stays.
Ingestion: Rinse mouth, drink water, do not induce vomiting, get medical help right away.
Note to Doctor: Treat symptomatically, be aware of the toxic effects of cobalt compounds.

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, foam, or carbon dioxide. Water spray for larger fires.
Unsuitable Media: Do not use strong water jets that might spread powder.
Specific Hazards: Emits toxic and irritating fumes like cobalt oxides when heated.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective clothing.
Advice: Avoid dust, keep out of smoke, contain contaminated water used for firefighting.

Accidental Release Measures

Personal Precautions: Ventilate area, wear respiratory protection, gloves, goggles, avoid contact and breathing dust.
Environmental Precautions: Prevent material from reaching drains, surface water, or soil. Alert authorities if product enters waterways.
Methods for Cleaning Up: Use HEPA vacuum or wet sweeping, avoid dry sweeping, collect in sealable container for disposal.

Handling and Storage

Handling: Handle in well-ventilated areas, minimize dust generation, avoid skin and eye contact, wash after use, don’t eat or drink in work area.
Storage: Store in tightly closed containers, in a cool, dry place, away from incompatible substances like acids and oxidizers, protect from moisture.

Exposure Controls and Personal Protection

Occupational Exposure Limits: ACGIH TLV for cobalt and inorganic compounds as Co: 0.02 mg/m3 (inhalable fraction)
Engineering Controls: Use enclosures, local exhaust ventilation to keep airborne levels below limits.
Respiratory Protection: Appropriate respirator if airborne dusts or fumes are present.
Skin Protection: Chemical resistant gloves, lab coats, or coveralls.
Eye Protection: Safety goggles or face shield.
Hygiene: Always wash hands after handling, do not bring contaminated gear home.

Ecological Information

Aquatic Toxicity: Harmful to aquatic organisms even at low concentrations.
Persistence and Degradability: Not easily biodegradable, persists in environment.
Bioaccumulation: Cobalt compounds may build up in certain aquatic species.
Mobility in Soil: Low water solubility limits movement through soil, but dust can travel.
Other Adverse Effects: Possible long-term environmental hazard due to cobalt’s toxicity to flora and fauna.

Disposal Considerations

Product Disposal: Treat as hazardous waste, send to licensed waste handler, follow local regulations.
Packaging Disposal: Decontaminate or puncture and dispose as industrial waste.
Precautions: Do not dump into sewers, on ground, or into any waterways.
Reuse / Recycling: Reuse allowed if uncontaminated and suitable for intended use, otherwise ensure proper disposal.
