First Aid Measures

General Advice: Move person from exposure. Remove contaminated clothing. Seek medical attention for all exposures
Inhalation: Move to fresh air. Keep at rest. Provide oxygen or artificial respiration if needed
Skin Contact: Rinse thoroughly with soap and water for several minutes. Remove contaminated clothing
Eye Contact: Flush eyes with plenty of water for 15 minutes. Lift eyelids to rinse completely. Remove contact lenses if present and easy to do
Ingestion: Rinse mouth. Do not induce vomiting. Give water to dilute. Get immediate medical help

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, CO2, water spray, or foam
Unsuitable Media: None known for this chemical
Fire Hazards: Non-combustible, but may emit toxic fumes of cobalt oxides and carbon compounds at high temperatures
Protective Equipment: Firefighters wear standard protective gear and self-contained breathing apparatus
Firefighting Instructions: Use water spray to cool containers. Keep people away from fire area unless wearing suitable protective equipment. Prevent fire-fighting run-off from entering waterways and drains

Accidental Release Measures

Personal Protection: Use personal protective equipment such as gloves, protective clothing, eye protection, and a respirator
Spill Response: Evacuate area. Prevent dust from dispersing. Sweep up material without generating dust and collect in suitable, closed containers for disposal
Environmental Precautions: Prevent spills from entering drains, surface water, or groundwater
Clean-Up Methods: Use HEPA-filtered vacuum or wet dust mop to avoid raising dust

Handling and Storage

Handling: Handle in a chemical fume hood or well-ventilated area. Minimize dust generation and accumulation. Avoid contact with skin, eyes, and clothing. Keep product in tightly closed containers when not in use
Storage: Store in a cool, dry, well-ventilated place away from incompatible substances including acids and strong oxidizers. Keep containers tightly sealed. Label containers clearly
Special Rules: Limit exposure to authorized, trained personnel only

Exposure Controls and Personal Protection

Occupational Exposure Limits: Cobalt compounds, as Co: ACGIH TLV-0.02 mg/m³ (TWA, inhalable fraction), OSHA PEL-0.1 mg/m³ (TWA, as Co)
Engineering Controls: Use fume hoods, process enclosures, local exhaust ventilation to minimize exposure
Personal Protective Equipment: Chemical-resistant gloves, safety goggles or glasses with side shields, laboratory coat or coveralls, proper respiratory protection (approved cartridge respirator if ventilation not adequate)
Hygiene Practices: Wash hands thoroughly before breaks and after use. Remove contaminated clothing and protective equipment before leaving work area

Toxicological Information

Routes of Exposure: Inhalation, skin absorption, ingestion, eye contact
Acute Toxicity: Toxic if swallowed, in contact with skin, or inhaled; LD50 Oral (rat): 1870 mg/kg (as cobalt compounds)
Chronic Toxicity: Chronic exposure can cause skin sensitization, respiratory sensitization (occupational asthma), and has been linked to increased cancer risk

Ecological Information

Ecotoxicity: Very toxic to aquatic life with long-term effects; cobalt ions bioaccumulate and cause adverse impacts on aquatic organisms
Bioaccumulation: Cobalt compounds tend to accumulate in aquatic and terrestrial organisms
Mobility in Soil: Moderate-to-high; can migrate, especially under acidic conditions
Persistence: Does not break down easily in the environment
Other Adverse Effects: Can impact soil microbial function and plant health

Disposal Considerations

Product Disposal: Dispose of in accordance with local, regional, and national regulations for hazardous waste. Do not release to environment
Contaminated Packaging: Triple rinse before disposal or offer to an approved waste disposal facility
