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 raising dust. Scoop or vacuum up using a vacuum system equipped with a HEPA filter. Place in properly labeled closed containers.

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 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 area. Store material tightly sealed in properly labeled containers. Protect from moisture. See section 10 for more information on incompatible materials.




Exposure Limits:      OSHA/PEL:                             ACGIH/TLV:

Lanthanum Fluoride     No exposure limit established     No exposure limit established

Fluorides (as F)           2.5 mg/m3                               2.5 mg/m3

Appropriate Engineering Controls: Handle in a controlled, enclosed environment. 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 dust or fumes 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:

Lanthanum Compounds:  In animal studies lanthanum chloride instilled intratracheally revealed that the metal remains mostly in the lungs with a biological half-life of 244 days. Oral administration of lanthanum chloride at 40mg/kg concentration indicated that chronic exposure to lanthanum could possibly impair the learning ability. Although swabbing of teeth with lanthanum nitrate is known to replace calcium with lanthanum in the enamel in rats and hamsters, lanthanum absorbed from the small intestine has also been shown to deposit in the teeth. Lanthanum carbonate, at doses up to 2000 mg/kg/day, did not affect fertility or mating performance of male or female rats.

Rare Earth Fluorides:  An animal study covered fluorides of rare-earth metals (REM) assigned to yttrium group--yttrium, terbium, ytterbium, and lutetium. Fluorides of REM have low toxicity and cumulativity, and induce no local irritation of skin and eyes. Fluorides of yttrium, terbium and lutetium, if administered into stomach, result in specific intoxication (fluorosis); fluoride of ytterbium did not cause such intoxication. According to short-term tests of cytotoxicity, the foreseeable fibrogenic danger for ytterbium fluoride is moderate, for fluorides of yttrium, terbium and lutetium is mild.
