Inhalation: Move person to fresh air, provide artificial respiration if needed, seek medical attention for persistent cough or difficulty breathing
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, apply moisturizer for irritation, seek attention for persistent redness or burns
Eye Contact: Rinse cautiously with water for at least 15 minutes, hold eyelids open, remove contact lenses if present and easy to do, consult physician if irritation or redness persists
Ingestion: Rinse mouth with water, do not induce vomiting, give small amount of water to rinse if victim is conscious, get medical help for persistent discomfort or nausea
Suitable Extinguishing Media: Use dry chemical, CO2, or foam; water spray for cooling containers
Unsuitable Extinguishing Media: No use of direct high-pressure water stream, risk of spread
Special Hazards: Combustible, decomposition releases carbon oxides, cerium oxides, organic vapors
Firefighter Protection: Wear self-contained breathing apparatus, full protective gear, keep upwind, prevent runoff from entering drains
Combustion Products: Cerium oxide dust, CO, CO2, acrid fumes possible under incomplete combustion
Spill Response: Wear personal protective equipment, ventilate area, prevent access to drains
Containment: Use inert absorbent like sand or vermiculite, collect in approved waste containers
Cleanup: Clean area with detergent and water after collection, avoid generating dust, use spark-proof tools
Personal Precautions: Avoid skin, eye contact and inhalation, restrict unprotected personnel
Environmental Precautions: Minimize entry to sewers, notify authorities in case of large spills
Handling: Use with adequate ventilation, avoid any sources of ignition, keep containers tightly sealed, use appropriate chemical-resistant gloves and glasses
Hygiene: Do not eat, drink, or smoke when working, wash hands after handling, promptly remove contaminated clothing
Storage: Keep in a cool, dry, well-ventilated area away from heat and humidity, store in tightly closed container made from compatible materials, segregate from strong oxidizing agents and acidic materials, use spill containment pallets for large quantities, ensure easy access to eyewash and safety shower stations
Occupational Exposure Limits: No specific national standard, advisable to keep airborne levels below nuisance dust threshold (10 mg/m3 for total dust)
Engineering Controls: Use local exhaust, maintain adequate general room ventilation, enclose processes
Personal Protection: Wear impervious nitrile or neoprene gloves, chemical safety goggles, flame resistant lab coat, use P95 or higher respirator if dust is generated
Other Precautions: Keep emergency eyewash and shower accessible, change clothing frequently if splashed

Chemical Stability: Stable for storage under recommended conditions, shelf life varies from several months to a year if sealed
Reactivity: Reacts with strong oxidizers, acids, generates heat and gases
Hazardous Polymerization: Not expected, even on extended storage
Hazardous Decomposition: Produces CO, CO2, cerium oxide fumes on thermal breakdown
Conditions to Avoid: Open flames, sparks, excessive heat, strong acids, oxidizers
Incompatible Materials: Oxidizing agents, strong acids, peroxides
Acute Toxicity: LD50 for oral and dermal exposure not precisely established; 2-ethylhexanoic acid reference: oral LD50 (rat) ~2000 mg/kg
Skin Corrosion / Irritation: Prolonged or repeated contact may cause dermatitis
Eye Damage / Irritation: Direct contact stings, may cause redness, tearing
Respiratory or Skin Sensitization: Prolonged inhalation of vapors or mists can irritate respiratory tract
Carcinogenicity: No evidence of carcinogenicity for cerium compounds; IARC, NTP, OSHA lists do not classify cerium isooctanoate
Reproductive Toxicity: 2-ethylhexanoic acid shows developmental toxicity in animal studies; caution advised
Other Effects: Metal compounds such as cerium may accumulate in body tissues over time, so long-term effects not completely understood
Toxicity to Aquatic Life: Harmful to aquatic organisms with long-lasting effects based on available data; 2-ethylhexanoic acid LC50 (fish) 85 mg/L (96 h)
Persistence and Degradability: Only partial breakdown expected in the environment, cerium salts remain in soil or sediment
Bioaccumulation Potential: Cerium compounds may accumulate in aquatic organisms
Mobility in Soil: Limited; binds to particulates, risk of runoff after spills
Other Adverse Effects: No known disruption of wastewater treatment microorganisms, product should be kept away from watercourses
Waste Disposal Method: Store waste in labelled, sealed containers; send for chemical incineration or landfill at an approved waste facility; do not dump down drains or ordinary trash
