V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of cerium oxide have not been thoroughly investigated and recorded.

Cerium salts increase the blood coagulation rate.  Exposure to cerium salts may increase sensitivity to heat, itching and skin lesions.  Large doses to experimental animals have caused writhing, ataxia, labored respiration, sedation, hypotension and death by cardiovascular collapse.

Acute Effects:

Inhalation:  May cause irritation to the respiratory tract and mucous membrane.  Dusts may cause asthma attacks and lung damage such as lung granulomas.  Large doses may cause writhing, loss of muscle coordination, labored respiration, sedation, hypotension and cardiovascular collapse.

Ingestion:  May cause gastrointestinal irritation.

Skin:  May cause irritation, rashes and skin granulomas.

Eye:  May cause irritation.

Chronic Effects:

Inhalation:  Prolonged or repeated inhalation may cause writhing, loss of muscle coordination, labored respiration, sedation, hypotension and cardiovascular collapse.

Ingestion:  May affect the coagulation rate of the blood.

Skin:  May cause irritation.

Eye:  No chronic health effects recorded.

Medical Conditions Possibly Aggravated by Overexposure:  Pre-existing respiratory disorders.

Carcinogenicity: NTP:  No                IARC:  No             OSHA:  No

 

EMERGENCY AND FIRST AID PROCEDURES:

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

INGESTION:  Give 1-2 glasses of milk or water and induce vomiting, seek medical attention.  Never induce vomiting or give anything by mouth to an unconscious person.

SKIN:  Remove contaminated clothing from affected area, brush material off skin, wash with soap and water.  Get medical attention if irritation develops or persists.

EYE:  Flush eyes with plenty of water for at least 15 minutes using an eyewash fountain.  Lift upper and lower lids and rinse well under them.  Get medical attention if irritation develops or persists.

 

 

VI.   REACTIVITY DATA

Stability:  Stable

Conditions to Avoid:  None

Incompatibility (Material to Avoid):  Oxidizing agents, strong acids.

Hazardous Decomposition Products:  None known

Hazardous Polymerization:  Will not occur

 

 

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled:  Wear appropriate respiratory and protective equipment specified in section VIII.  Isolate spill area and provide ventilation.  Sweep or vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal.  Avoid creating dusting conditions.

Waste Disposal Method:  Dispose of in accordance with Local, State and Federal Waste Disposal Regulations.

 

 

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  NIOSH approved dust mask under dusting conditions.

Ventilation:  Provide adequate ventilation.  Use local exhaust under dusting conditions.

Protective Clothing:  Work clothing and gloves.  When used for glass polishing, the suspensions of polish become alkaline (pH >- 8.5) following he hydrolysis of the glass.  It is strongly recommended that gloves and goggles be worn to prevent contact with skin and eyes.

Eye Protection:  Safety glasses with side shields.  Chemical workers goggles (when using for glass polishing.)

Other Protective Equipment:  Maintain a sink and eyewash fountain in the work area.

 

 

IX.   SPECIAL PRECAUTIONS

Handling and Storage:  Store in a cool, dry place in tightly closed containers.  Avoid breathing dusts.  Avoid direct or prolonged contact with skin and eyes.  Wash hands thoroughly after handling.  Do not rub eyes with soiled hands.  Do not eat, drink or smoke in the work area.

Other Precautions:  Dry powders can build static electricity charges when subjected to the friction of conveying, mixing or sliding.  To prevent ignition, provide adequate precautions, such as electrical grounding, or inert atmospheres when material is used in the presence of flammable materials.

Work Practices:  Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels.  Use good housekeeping and sanitation practices.  Do not use tobacco or food in work area.  Wash thoroughly before eating and smoking.  Do not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.

TSCA Listed:         Yes
