Chemical Name: Potassium Cerium Nitrate
CAS Number: 10294-44-8
Concentration: >98% by weight
Impurities: Trace elements such as potassium nitrate or cerium oxide below 1% total
Other Ingredients: No other ingredients considered hazardous under GHS
Eye Contact: Flush eyes with plenty of water for 15 minutes, lifting upper and lower lids often. Remove contact lenses if possible. Seek immediate medical attention.
Skin Contact: Wash affected area with soap and water. Remove contaminated clothing. If irritation persists, get medical advice.
Inhalation: Move to fresh air. Seek medical attention if symptoms like cough or difficulty breathing develop.
Ingestion: Rinse mouth with water. Do not induce vomiting. Seek immediate medical assistance.
Symptoms: May include redness, irritation, burning of skin or eyes, nausea, vomiting on ingestion
Suitable Extinguishing Media: Use water spray, dry chemical, or CO2 for surrounding fire. Do not use dry chemical directly on product.
Specific Hazards: Oxidizer increases risk and intensity of fire. Can release toxic nitrogen oxides and cerium fumes when heated.
Protective Equipment: Firefighters require full protective gear and self-contained breathing apparatus.
Firefighting Instructions: Avoid contact with water-reactive materials. Cool containers exposed to fire with water from safe distance. Evacuate area and contain run-off.
Explosion Hazards: May cause ignition of combustible material.
Personal Precautions: Prevent exposure by wearing gloves, goggles, and suitable respirator. Evacuate unnecessary personnel.
Environmental Precautions: Prevent spill from entering drains, sewers, or waterways. Notify authorities of major leaks.
Cleanup Methods: Sweep up material using non-sparking tools, avoiding dust generation. Place into suitable, labeled container for disposal. Ventilate area well. Decontaminate equipment and wash hands thoroughly.
Spill volume: Contain large spills with earth or non-combustible absorbent.
Safe Handling: Avoid contact with skin and eyes. Do not breathe dust. Ground and bond containers and equipment. Handle away from heat, sparks, and incompatible substances.
Storage Conditions: Store in cool, dry, well-ventilated place separate from flammables, acids, and reducing agents. Keep container tightly closed. Protect from physical damage and moisture.
Incompatible Materials: Strong acids, organic materials, reducing agents, combustibles.
Specific Use Considerations: Restrict access to authorized, adequately trained personnel.
Exposure Limits: No established occupational exposure limit for this compound. Avoid prolonged or repeated exposure.
Engineering Controls: Use in well-ventilated area, preferably with local exhaust.
Personal Protection: Use NIOSH-approved dust respirator, chemical safety goggles, protective gloves (nitrile or latex), and long-sleeved laboratory coat.
Hygiene Measures: Wash hands after handling, remove contaminated clothing before leaving work area.
Monitoring: Regular air and surface sampling in work area recommended.

Conditions to Avoid: Heat, sparks, flames, mechanical shock, moisture
Incompatible Materials: Flammable substances, organic material, acids, reducing agents, powdered metals
Hazardous Decomposition Products: Nitrogen oxides, cerium oxides, potassium oxides upon heating or combustion
Reactivity: Strongly oxidizing, can violently react with incompatible materials
Routes of Exposure: Skin, eyes, ingestion, inhalation
Acute Toxicity: Harmful if swallowed; LD50 Oral (rat): approximately 200-500 mg/kg
Skin Irritation: May cause redness, itching, and discomfort
Eye Irritation: Can cause serious irritation or damage due to its oxidizing properties
Inhalation Effects: Dust may cause respiratory tract irritation. Prolonged or repeated exposure could damage mucous membranes.
Chronic Effects: Evidence for long-term toxicity is limited; repeated exposure could affect kidneys, liver, and respiratory tract by analogy to similar nitrates and cerium salts
Toxicity to Aquatic Life: Expected to be toxic to aquatic organisms, possibily causing long-lasting effects in large spills
Persistence and Degradability: Inorganic salt unlikely to degrade by environmental processes
Bioaccumulation Potential: Not expected to bioaccumulate
Mobility in Soil: Dissolves readily in water, may migrate through soil to groundwater
Other Adverse Effects: Releases nitrate ions, which contribute to eutrophication and potential for algal blooms in water bodies
Product Disposal: Treat as hazardous chemical waste. Dispose using licensed hazardous waste contractor. Do not release into municipal sewers or unapproved landfills.
Container Disposal: Rinse empty containers with plenty of water. Dispose following local, state, and federal guidelines.
Special Precautions: Neutralize leftover chemical cautiously under expert guidance. Notify environmental authorities in event of significant discharge.
