Other Components: Trace residual water or process by-products below 1%
General Recommendation: Move away from exposure source. Call emergency medical services if symptoms persist.
Inhalation: Remove individual to fresh air, keep at rest, seek medical advice if breathing issues develop.
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, seek medical attention if irritation persists.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, remove contact lenses if present, get medical help promptly.
Ingestion: Rinse mouth thoroughly, do not induce vomiting, get immediate medical attention
Important Symptoms: Coughing, redness, burning, nausea, abdominal pain or vomiting
Suitable Extinguishing Media: Water spray, dry chemical powder, foam. Use large amounts of water for major fires.
Unsuitable Media: Do not use dry chemical on large oxidizer fires; avoid carbon dioxide extinguishers for nitrate fires.
Special Hazards: Oxidizing substance, may react violently with combustibles. Intense heat may release toxic fumes of nitrogen oxides and cerium compounds.
Protective Equipment: Wear SCBA and full fire-resistant gear.
Precautions: Evacuate area, keep containers cool with water spray, use remote means to fight fire if possible.
Decomposition Products: Cerium oxides, sodium oxides, nitrogen oxides
Personal Precautions: Evacuate unnecessary personnel, restrict access. Wear chemical-resistant gloves, safety goggles, NIOSH-approved respirator where required.
Environmental Precautions: Prevent entry to drains, soil, or watercourses. Notify environmental authorities if large quantities enter environment.
Methods for Clean-Up: Scoop spilled powder into clean, dry, sealed containers using non-sparking tools. Flush residue with plenty of water while minimizing runoff. Avoid creating dust.
Further Handling: Wash affected area after cleanup, ventilate area. Dispose of contaminated materials following regulations.
Safe Handling: Operate in well-ventilated spaces, away from heat sources, flames, and all combustibles. Keep containers tightly closed when not in use. Wear appropriate PPE and use only clean, dry, non-sparking equipment.
Safe Storage Conditions: Store in cool, dry, corrosion-resistant container. Keep separate from reducing agents, organic materials, strong acids, flammable substances.
Storage Incompatibilities: Avoid storing with paper, wood, oil, or other flammable/combustible items.
Packaging: Use containers made from compatible materials (glass, HDPE, or coated metal). Label containers with content and hazard information.
Occupational Exposure Limits: No established OSHA or ACGIH exposure limits for sodium cerium nitrate. Use local dust limits (nuisance dust, total or respirable fraction) as guidance.
Engineering Controls: Use local exhaust ventilation, process isolation. Enclose sources of dust.
Personal Protective Equipment (PPE): Wear chemical-resistant gloves (nitrile or neoprene), lab coat or apron, approved safety goggles or face shield. Respiratory protection recommended in dust-generating operations.
Hygiene Measures: Wash hands after handling. Do not eat, drink, or smoke in work areas. Remove contaminated clothing and wash before reuse.

Acute Toxicity: Moderately toxic by oral route; LD50 (rat) estimated 300–2000 mg/kg.
Skin/Eye Irritation: Irritant to eyes and skin; may cause serious eye damage.
Inhalation: Dust may cause respiratory irritation, coughing, and throat discomfort.
Chronic Effects: Prolonged exposure may affect liver, kidney, or respiratory tract; data on long-term effects limited.
Sensitization: Not reported to cause sensitization
Mutagenicity/Carcinogenicity: No data showing mutagenic or carcinogenic effects for this compound
Target Organs: Eyes, skin, respiratory and digestive systems
Ecotoxicity: Limited aquatic toxicity data available; cerium compounds may affect aquatic invertebrates at high concentrations.
Persistence/Degradability: Inorganic compound, not biodegradable.
Bioaccumulation: Cerium not known for significant bioaccumulation potential.
Mobility: Readily soluble in water, potential for migration through soil and water systems.
Environmental Precautions: Prevent release to environment due to oxidizing properties and potential harm to organisms in high concentrations.
Disposal Methods: Dispose as hazardous waste according to local, state, and national regulations. Do not release into drains or environment.
Container Disposal: Rinse containers thoroughly before reuse or recycling. Dispose of rinse water as hazardous waste.
Recommended Treatment: Secure in sealed, labeled waste drums for hazardous landfill. Chemical treatment neutralization methods under authority may apply.
Precautions: Never incinerate in enclosed space due to risk of toxic fume evolution. Documentation of disposal procedures for regulatory compliance.
