Molecular Weight: 195.9 g/mol
Inhalation: Remove to fresh air immediately, administer oxygen if breathing is difficult, seek emergency medical attention
Skin Contact: Take off contaminated clothing, wash skin thoroughly with soap and water for at least 15 minutes, seek medical help if irritation persists
Eye Contact: Rinse eyes under gentle running water for several minutes, lifting eyelids occasionally, get immediate medical attention
Ingestion: Do not induce vomiting, rinse mouth thoroughly with water if conscious, never give anything by mouth to an unconscious person, seek immediate medical assistance
Symptoms: Burning sensation, coughing, shortness of breath, headache, nausea, dizziness, skin redness or pain, visual disturbance
Notes for Physicians: Treat symptomatically, monitor respiratory and cardiac function, provide oxygen or artificial respiration as required
Suitable Extinguishing Media: Foam, carbon dioxide, dry chemical, do not use water
Specific Hazards: Flammable liquid, vapor may form explosive mixtures with air, combustion releases toxic gases including carbon monoxide and iron oxides
Special Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Firefighting Procedures: Evacuate area, approach from upwind, fight fire from maximum distance
Explosion Hazards: Vapors may travel to source of ignition and flash back, explosion risk in confined spaces
Hazardous Decomposition Products: Carbon monoxide, iron oxides, metal fumes
Personal Precautions: Evacuate personnel, provide adequate ventilation, avoid breathing vapor, wear protective equipment including chemical-resistant gloves and eyewear
Environmental Precautions: Prevent product from entering drains or watercourses, contain spill with non-combustible absorbent material
Spill Cleanup Methods: Absorb with sand, earth or vermiculite, collect in a suitable container for disposal, ventilate the area, wash spill site after material pickup is complete
Emergency Procedures: Remove all ignition sources, isolate hazard area, notify authorities if situation cannot be controlled without risk
Disposal of Contaminated Material: Label and dispose according to national and local regulations, do not discharge into sewers or environment
Handling: Handle in well-ventilated areas, keep container tightly closed, avoid contact with skin, eyes, and clothing, use only non-sparking tools, ground containers when transferring liquid
Storage: Store in a cool, dry, well-ventilated place away from sources of ignition, keep out of direct sunlight, segregate from oxidizing agents and acids, use approved containers compatible with iron pentacarbonyl, post “No Smoking” signs in storage area
Special Requirements: Keep containers tightly sealed when not in use, check regularly for leaks or corrosion, store away from food, drink, or animal feed
Occupational Exposure Limits: OSHA PEL: 0.1 ppm (TWA), ACGIH TLV: 0.1 ppm (TWA)
Engineering Controls: Local exhaust ventilation to maintain concentrations below exposure limits, explosion-proof equipment in flammable atmospheres
Respiratory Protection: Use approved respirator with appropriate chemical cartridge or supplied-air respirator for higher concentrations
Skin Protection: Wear impervious gloves (nitrile, butyl rubber preferred), laboratory coat, coveralls or other body protection
Eye Protection: Safety goggles and face shield
Hygiene Measures: Wash hands and face after handling, do not eat or drink in work area, remove contaminated clothing and clean before reuse

Hazardous Decomposition: Carbon monoxide, iron oxides, metallic iron residues
Hazardous Polymerization: Will not occur
Reactivity: Liberates toxic carbon monoxide gas on decomposition, reacts violently with oxidizing chemicals
Acute Toxicity: Highly toxic via inhalation, oral, and dermal exposure; Lethal in small amounts (LD50 oral rat: 30 mg/kg)
Routes of Exposure: Inhalation, skin absorption, eye contact, ingestion
Chronic Toxicity: May cause cumulative health issues with repeated exposure, affects nervous system, kidneys, and lungs
Symptoms: Dizziness, nausea, vomiting, chest pain, headache, difficulty breathing, convulsions, unconsciousness
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA
Mutagenicity/Reproductive Toxicity: Data insufficient for classification
Other Information: Prolonged or repeated exposures may sensitize skin or respiratory tract
Ecotoxicity: Very toxic to aquatic life; acute and chronic effects observed in aquatic organisms
Persistence and Degradability: Not readily biodegradable, decomposes slowly in air and water to form iron oxides and carbon monoxide
