Safety Data Sheet
per 29 CFR 1910.1200 Page 2 of 4
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: See section 11 for more information.
Indication of Immediate Medical Attention and Special Treatment: No other relevant information available.
5 FIREFIGHTING MEASURES
Extinguishing Media: Use Class D dry powder extinguishing agent.
Unsuitable Extinguishing Media: Do not use water.
Specific Hazards Arising from the Material: Flammable in the form of dust when exposed to heat, spark or flame. May
react with water under fire conditions liberating flammable hydrogen gas. May emit fumes of samarium oxide 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.
6 ACCIDENTAL RELEASE MEASURES
Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective
equipment specified in section 8. Isolate spill area. Avoid dust formation. Avoid contact with skin and eyes. Avoid breathing
dust or fume. Eliminate all sources of ignition.
Methods and Materials for Containment and Cleaning Up: Sweep or scoop spilled product and place in a closed
container for further handling and disposal. Use only non-sparking tools and natural bristle brushes.
Environmental Precautions: Do not allow to enter drains or to be released to the environment.
7 HANDLING AND STORAGE
Precautions for Safe Handling: Handle in an enclosed, controlled process, under dry protective gas such as argon when
possible. Air and moisture sensitive. Protect from sources of ignition. Avoid contact with skin and eyes. Wash thoroughly
before eating or smoking.
Conditions for Safe Storage, Including Any Incompatibilities: Samarium metal should be stored in tightly-closed
containers under argon or mineral oil. Store in a cool, dry area. Protect from moisture. See section 10 for more information
on incompatible materials.
8 EXPOSURE CONTROLS AND PERSONAL PROTECTION
Exposure Limits: Samarium
OSHA/PEL: No exposure limit established
ACGIH/TLV: No exposure limit established
Appropriate Engineering Controls: Handle in a humidity controlled atmosphere. Handle in an enclosed, controlled process
under dry argon when possible. Ensure adequate ventilation to maintain exposures below occupational limits. 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: If permissible levels are exceeded, use NIOSH approved dust respirator.
Eye Protection: Safety glasses
Skin Protection: Wear impermeable gloves, protective work clothing as necessary.
