Common Names and Synonyms: Cerous nitrate hexahydrate; nitric acid,cerium(3+) salt, hexahydrate.




General Measures: Remove patient from area of exposure.

INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek medical attention.

INGESTION: Rinse mouth with water. Do not induce vomiting. Seek medical attention. Never induce vomiting or give anything by mouth to an unconscious person.

SKIN: Remove contaminated clothing, brush material off skin, wash affected area with soap and water. Seek medical attention if symptoms persist.

EYES: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persist.

Most Important Symptoms/Effects, Acute and Delayed: May cause irritation. See section 11 for more information.

Indication of Immediate Medical Attention and Special Treatment: No other relevant information available.




Extinguishing Media: Use suitable extinguishing agent for surrounding materials and type of fire.

Unsuitable Extinguishing Media: No information available.

Specific Hazards Arising from the Material: May emit toxic fumes under fire conditions.

Special Protective Equipment and Precautions for Firefighters: Full face, self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.




Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Isolate spill area and provide ventilation. Avoid breathing dust or fume. Avoid contact with skin and eyes. Eliminate all sources of ignition.

Methods and Materials for Containment and Cleaning Up: Avoid dust formation. Cleanup spills with a vacuum system utilizing a high efficiency particulate air (HEPA) filtration system and place in a closed container for further handling and disposal.

Environmental Precautions: Do not flush to sewer, stream, or other bodies of water. Do not allow to enter drains or to be released to the environment.




Precautions for Safe Handling: Handle under dry protective gas such as argon if possible. Handle in an enclosed, controlled process. Avoid creating dust. Provide adequate ventilation if dusts are created. Avoid breathing dust or fumes. Avoid contact with skin and eyes. Wash thoroughly before eating or smoking. See section 8 for information on personal protection equipment.

Conditions for Safe Storage, Including Any Incompatibilities: Store in a cool, dry, well-ventilated area. Store in a tightly sealed container, under argon if possible. Protect from water and moisture. Storage area should be free of combustibles. Do not store together with reducing agents. See section 10 for more information on incompatible materials.




Exposure Limits:   OSHA/PEL:                              ACGIH/TLV:

Cerium Nitrate         No exposure limit established      No exposure limit established

Appropriate Engineering Controls: Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air.

Individual Protection Measures, Such as Personal Protective Equipment:

   Respiratory Protection: Wear a NIOSH/MSHA approved respirator when high concentrations are present.

   Eye Protection: Safety glasses

   Skin Protection: Wear impermeable gloves, protective work clothing as necessary.

Likely Routes of Exposure: Inhalation, skin and eyes.

Symptoms of Exposure: May cause irritation to eyes and abraded skin. May cause irritation to lungs.

Acute and Chronic Effects:

Cerium Compounds: Cerium compounds are mildly to moderately toxic, depending on the particular compound. In an animal study, cerium carbonate, cerium fluoride, and cerium oxide were not found to be acutely toxic, showed no signs of dermal irritation, and were minimally irritating to eyes. Cerium chloride was found to be more acutely toxic (LD50 oral - rat - 1291 Ce/kg), and a severe skin irritant.

Rare Earth Nitrates: Results of acute toxicity studies on rare earth nitrates indicate that their acute toxicity is highly dependent on the route of administration. The nitrate salts were moderately toxic when given intraperitoneally to rats and mice and only slightly toxic when administered orally to rats.

Acute Toxicity: No data

Carcinogenicity: NTP: Not identified as carcinogenic   IARC: Not identified as carcinogenic
