First Aid Measures

General Advice: Move to fresh air, keep warm and at rest
Inhalation: Take person to fresh air, provide oxygen if difficult breathing, seek medical advice
Skin Contact: Remove contaminated clothing, wash skin with soap and water for 15 minutes, seek medical attention if irritation persists
Eye Contact: Rinse immediately under running water for minimum 15 minutes, hold eyelids apart, consult physician urgently
Ingestion: Rinse out mouth, do not induce vomiting, drink 1-2 glasses water, seek immediate medical attention

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, carbon dioxide, or foam
Unsuitable Extinguishing Media: Avoid water jet—may spread fire
Special Hazards: Product may emit toxic metal oxides or hydrocarbons when burned; container may rupture in heat
Protective Equipment: Firefighters wear self-contained breathing apparatus (SCBA), full protective gear
Other Recommendations: Cool exposed containers with water spray, remove them if possible without risk

Accidental Release Measures

Personal Protection: Use personal protective equipment (PPE): gloves, goggles, chemically resistant clothing
Environmental Precautions: Prevent spills from reaching drains, soil, surface and groundwater
Clean-up Methods: Absorb material on inert, non-combustible medium (sand, soil, vermiculite), sweep up, place in sealed container for disposal
Spill Area: Ventilate area, wash thoroughly after clean-up, dispose contaminated materials as hazardous waste
Decontamination: Wash area with suitable detergent and water, avoid run-off into sewers

Handling and Storage

Handling: Avoid inhalation, ingestion, and contact with eyes or skin, use under chemical fume hood, keep away from ignition sources
Storage Conditions: Store in tightly closed containers, cool dry place, separate from oxidizers and acids
Packaging Materials: Use compatible and clearly labeled containers, avoid reactive metals
Special Precautions: Ensure good ventilation, prevent static discharge, train workers in proper procedures
Incompatibilities: Keep away from strong acids, bases, oxidizing materials

Exposure Controls and Personal Protection

Engineering Controls: Operate in chemical fume hood, use local exhaust ventilation to keep airborne concentrations low
Exposure Limits: OSHA, ACGIH not established for most metallocenes; keep as low as reasonably achievable
Respiratory Protection: Use NIOSH-approved respirator in absence of adequate ventilation
Skin Protection: Chemical-resistant gloves (nitrile, neoprene), lab coat or apron
Eye Protection: Tight-fitting safety goggles or face shield
Other: Emergency shower and eyewash station in area, no eating or drinking in work area

Physical and Chemical Properties

Appearance: Orange-red (ferrocene), yellowish, or white depending on metal center, crystalline powder
Odor: Faint hydrocarbon smell
Melting Point/Range: 172–173°C for ferrocene, varies for other metallocenes
Boiling Point/Range: Decomposes before boiling
Solubility: Slightly soluble in water, soluble in organic solvents (benzene, ether, toluene)
Vapor Pressure: Low at room temperature
Density: 1.5–1.9 g/cm³ (depending on metal center)
Flash Point: Typically above 100°C
Explosive Properties: No data for most, not expected to be explosive
Partition Coefficient (n-octanol/water): Log P varies, moderately lipophilic
Autoignition Temperature: Above 400°C (varies by compound)

Stability and Reactivity

Chemical Stability: Stable under recommended storage and handling, sensitive to strong oxidizers
Conditions to Avoid: Heat, sparks, open flame, incompatible materials
Incompatibilities: Acids, oxidizing agents, strong bases, halogens
Hazardous Decomposition: Metal oxides, CO, CO2, other toxic fumes
Polymerization: Product does not undergo hazardous polymerization

Toxicological Information

Acute Effects: Inhalation or dermal exposure causes irritation, ingestion may harm internal organs
Chronic Exposure: Repeated exposure may result in liver or kidney impairment, not classified as carcinogenic in most jurisdictions
LD50/LC50: Varies by compound, e.g., Ferrocene Oral Rat LD50 approx. 1320 mg/kg
Skin/Eye Irritation: May cause serious burns, sustained redness, tearing, blurred vision
Sensitization: No evidence of sensitization
Other Effects: Effects on nervous system or blood have not been ruled out for all metal centers

Ecological Information

Ecotoxicity: Toxic to aquatic organisms, even at low concentrations
Persistence/Degradability: Degrades slowly in environment, some metallocenes persist in soil/sediment
Bioaccumulation: Possible for some metallocene species, low to moderate potential
Mobility in Soil: Limited mobility, higher in sandy or porous environments
Additional Information: Prevent chemical from reaching water bodies; long-term environmental effects not fully understood

Disposal Considerations

Waste Treatment Methods: Dispose through authorized hazardous waste contractor
Disposal of Containers: Empty containers must be handled as hazardous; destroy by incineration at licensed facility
Preventive Measures: Do not flush into surface water, sewer system, or soil
Reuse/Recycle: Not recommended due to risk of contamination, always follow federal and local regulations
