Impurities: No significant impurities known that influence classification or contribute to hazards
Eye Contact: Flush with plenty of water for 15 minutes, keep eyelids apart, seek medical attention if irritation persists
Skin Contact: Remove contaminated clothing, wash skin with plenty of soap and water, medical care if symptoms occur
Inhalation: Move to fresh air, offer oxygen if breathing is difficult, get medical aid if symptoms develop
Ingestion: Rinse mouth, do not induce vomiting. Drink water if conscious, get medical help immediately
Suitable Extinguishing Media: Dry chemical, CO2, foam, water spray (avoid full water jet which may spread product)
Unsuitable Extinguishing Media: None known for normal quantities
Special Hazards: May produce hazardous decomposition products in a fire such as carbon oxides, nitrogen oxides, cerium oxides
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective clothing for large fires; keep containers cool with water spray
Specific Firefighting Methods: Approach fire from upwind, keep runoff out of sewers and water supplies
Personal Precautions: Use personal protective equipment as required. Avoid dust formation, ventilate the area well
Environmental Precautions: Prevent material from entering drains or surface water. Avoid release into the environment
Methods for Clean-up: Pick up mechanically and place in a suitable, labeled container for waste disposal. Use damp cloth to wipe dust, avoid sweeping dry
Handling: Use only in well-ventilated places, avoid contact with skin, eyes, and clothing, do not ingest, wash hands before eating or drinking
Storage Conditions: Store tightly sealed in a dry, cool, and well-ventilated area, away from direct sunlight and incompatible substances such as strong acids and oxidizers
Storage Temperature: 2–8°C is ideal, keep away from sources of ignition and moisture
Exposure Limits: No established ACGIH or OSHA exposure limits for Cerium Citrate
Engineering Controls: Local exhaust ventilation, laboratory fume hood for powder handling
Personal Protective Equipment: Nitrile gloves, goggles, lab coat; NIOSH-approved respirator where dust may be generated
Hygiene Measures: Wash hands and face thoroughly after handling, keep contaminated clothing apart from other clothing
Appearance: White to pale yellow fine powder

Reactivity: Weakly reactive, avoid strong acids and oxidizing agents
Hazardous Reactions: Contact with strong oxidizers or acids may cause decomposition, releasing toxic gases
Conditions to Avoid: Excessive heat, moisture, incompatible substances
Hazardous Decomposition Products: Cerium oxides, carbon oxides, nitrogen oxides
Acute Toxicity: Low oral toxicity based on available animal data
Skin Contact: May cause mild irritation based on experience
Eye Contact: Causes moderate to severe irritation; eye contact can be damaging if not promptly rinsed out
Inhalation: Dust inhalation can lead to upper respiratory irritation (cough, sore throat, sneezing)
Chronic Effects: Limited studies; chronic exposure to rare earth compounds sometimes linked to lung and liver effects
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA
Other Information: No clear evidence of reproductive or developmental toxicity
Toxicity: Low acute toxicity to aquatic life is expected; detailed ecological studies limited for this compound
Persistence and Degradability: Inorganic salt; not expected to biodegrade
Bioaccumulation Potential: Not anticipated to bioaccumulate significantly in aquatic or terrestrial food chains
Mobility in Soil: Moderate based on water solubility; may bind to soil particles
