General: Move affected person from exposure. Seek medical aid for all significant exposures.
Inhalation: Move to fresh air, monitor for breathing difficulties, seek immediate medical attention if symptoms persist.
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, use emollient if irritation develops, medical evaluation if reaction persists.
Eye Contact: Flush eyes with clean water for at least 15 minutes. Do not rub. Remove contact lenses if present and easy to do. Medical evaluation recommended.
Ingestion: Rinse mouth with water, do not induce vomiting unless directed by medical professional. Transport to hospital.
Symptoms: Coughing, sore throat, skin rash, redness, discomfort to mouth or throat.
Advice to Physician: Treat symptomatically, monitor for cobalt allergy and delayed respiratory effects.
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray for large fires
Unsuitable Media: Avoid jet of water which may spread powder
Fire Hazards: Not flammable or combustible. Heated containers may rupture. Decomposition products can include toxic metal oxide fumes.
Protective Equipment: Full firefighting gear, self-contained breathing apparatus recommended.
Hazardous Combustion Products: Cobalt oxides, carbon monoxide and dioxide
Advice: Limit run-off with sand or earth to avoid environmental contamination.
Personal Precautions: Avoid contact with skin, eyes and clothing, do not breathe dust. Ventilate area. Use personal protective equipment including gloves, goggles, and certified dust respirator.
Environmental Precautions: Prevent further leakage or spillage if safe. Do not let product enter drains, sewers, or watercourses.
Cleanup Methods: Sweep up without creating dust, shovel into suitable labeled containers for disposal. Clean area with wet cloth or HEPA vacuum. Wash contaminated area with plenty of water.
Disposal: Follow local, regional or national regulations for chemical waste.
Handling: Work in well-ventilated area, minimize dust generation, avoid direct contact. Always use secondary containment when handling in bulk. Wash hands thoroughly after handling.
Storage Conditions: Store in closed containers, away from incompatible chemicals. Keep in dry, cool, well-ventilated location. Avoid extreme heat, light and moisture. Ensure labeling is clear.
Incompatible Materials: Strong acids, reducing agents, oxidizers can cause hazardous reactions.
Specific Hygiene Measures: Remove contaminated clothing and wash before reuse. Prohibit eating, drinking, smoking in storage and use areas.
Occupational Exposure Limits: ACGIH TLV for cobalt: 0.02 mg/m3 (TWA, inhalable fraction). Check national regulations for variance.
Engineering Controls: Local exhaust ventilation at point of generation. Enclosed process equipment, keep containers closed.
Personal Protective Equipment: Use chemical-resistant gloves, safety goggles or face shield, protective clothing. For dusty operations, use NIOSH-approved respirator.
Hygiene Practices: No food, drink or tobacco use in work area. Wash thoroughly before breaks and at end of workday.
