Inhalation: Remove exposed person to fresh air, keep comfortable, provide oxygen if breathing becomes difficult, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing and shoes, immediately wash skin with soap and plenty of water, seek medical advice if irritation develops or persists
Eye Contact: Flush open eyes gently with lukewarm water for at least 15 minutes, occasionally lifting lower and upper eyelids, obtain medical attention
Ingestion: Rinse mouth thoroughly, do not induce vomiting, provide water if victim is conscious, call poison control or seek immediate medical help
Most Important Symptoms: Allergic skin reaction, headaches, nausea, dizziness, abdominal pain with ingestion
Extinguishing Media (suitable): Alcohol-resistant foam, dry powder, CO₂, water spray (never use direct water stream)
Hazards from Combustion: Toxic fumes, including carbon monoxide, carbon dioxide, metal oxides
Protective Equipment: Self-contained breathing apparatus, full protective gear
Special Instructions: Cool exposed containers with water spray to prevent pressure build-up and bursting; keep people away from fire, control runoff
Personal Precautions: Evacuate unprotected personnel, avoid breathing vapors, use protective equipment
Spill Response: Remove all ignition sources, stop source of leak if safe, contain spill with non-combustible absorbent (sand, vermiculite), gather residue in chemical waste container
Environmental Precautions: Prevent entry into drains, surface and ground water
Clean-Up Methods: Ventilate area, decontaminate with detergent and large amounts of water, properly dispose of contaminated materials
Safe Handling: Work with good local exhaust/ventilation, avoid breathing in fumes, maintain good industrial hygiene, wash hands after handling, keep away from open flame and heat
Safe Storage: Store in closed, labeled metal containers in cool, dry, well-ventilated spaces away from direct sunlight and oxidizing agents
Special Precautions: Do not eat, drink, or smoke near chemical; containers may remain hazardous when empty, follow chemical safety protocols
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below exposure limits
Exposure Limits (as Cobalt): OSHA PEL 0.1 mg/m³, ACGIH TLV 0.02 mg/m³
Personal Protection: Wear chemical-resistant gloves (nitrile, neoprene), safety goggles, face shield, long-sleeved clothing, and in risk of high exposure, use air-purifying respirator fitted with organic vapor cartridge
Hygiene Measures: Wash hands and face after handling, do not carry contaminated clothing outside work area, dispose of protective equipment properly

Auto-Ignition Temperature: Approx. 230°C
Explosion Limits: Lower 0.6%, Upper 7.0% (solvent mix)
Chemical Stability: Stable under normal conditions and recommended use
Reactivity: Reacts with strong oxidizers, acids; may form peroxides with extended air exposure
Decomposition: Produces toxic fumes upon heating, can release metal oxides and hydrocarbons
Conditions to Avoid: Heat, sparks, flames, direct sunlight, incompatible chemicals
Hazardous Polymerization: Will not occur under typical storage and use
Acute Toxicity: Harmful by inhalation, ingestion, or skin absorption
Irritation: Can cause skin and serious eye irritation
Sensitization: Prolonged contact triggers allergic skin reactions
Chronic Effects: Cobalt compounds may cause organ damage (heart, thyroid, blood system) and are classified as possible carcinogens (IARC Group 2B)
Other Health Effects: Symptoms of overexposure include headaches, nausea, fatigue, dermatitis, and respiratory discomfort
Aquatic Toxicity: Toxic to aquatic life, especially invertebrates and fish
Persistence and Degradability: Limited biodegradability; long-term effects possible in environment
Bioaccumulative Potential: Cobalt compounds and hydrocarbons may accumulate in organisms
Mobility in Soil: Can migrate in groundwater as soluble salts
Other Environmental Effects: Risk of long-term ecological harm, runoff can damage aquatic habitats
Product Disposal: Treat as hazardous waste; incinerate in licensed facility or dispose according to local and national regulations
Packaging Disposal: Triple rinse and offer drums for recycling or reconditioning; puncture and dispose of small containers in compliance with official guidance
