Section 4: First-Aid Measures

Description of first aid measures: In case of inhalation: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek medical attention. In case of skin contact: Remove contaminated clothing, brush material off skin, wash affected area with soap and water. Seek medical attention if symptoms persist. In case of eye contact: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persist. In case of ingestion: Rinse mouth with water. Do not induce vomiting. Seek medical attention. Never induce vomiting or give anything by mouth to an unconscious person.

Most important symptoms and effects, both acute and delayed: Inhalation: Inhalation of dusts may be damaging to the health of the individual. Material may cause respiratory irritation in some persons. Persons with impaired respiratory function, airway diseases and conditions such as emphysema or chronic bronchitis may incur further disability if excessive concentrations of particulate are inhaled. Eyes: Material can cause eye irritation and damage in some persons. Contact the eye by metal dusts may cause mechanical abrasion or foreign body penetration of the eyeball. Skin contact: Not thought to produce adverse health effects following contact; however, open cuts, abraded or irritated skin should not be exposed to this material. Entry into the bloodstream through cuts, abrasions or lesions may produce systemic injury with harmful effects. Ingestion: Not normally a hazard due to the physical form of the product. However, accidental ingestion of the material may be damaging to the health of the individual. Lanthanide poisoning causes immediate defecation, writhing, incoordination, laboured breathing, and inactivity. Respiratory and heart failure may follow, causing death. Indication of any immediate medical attention and special treatment needed: Treat symptomatically. Show this safety data sheet to a physician or emergency room.

Section 5: Fire-Fighting Measures

Extinguisher media: Suitable extinguisher media: Use Class D dry powder extinguishing agent. Unsuitable extinguishing media: Water spray. Special hazards arising from the mixture: 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 ytterbium oxide under fire conditions. Advice for fire-fighters: Full face, self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes. Further information: None.

Section 6: Accidental Release Measures

Personal precautions, protective equipment and emergency procedures: Personal precautions: 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. If conditions are dusty, eliminate all sources of ignition.

First Print Date: 5-Mar-2015 Revision Date: 31-Aug-2019 Version: 1.1.1.

Environmental precautions: Prevent product from entering drains. Prevent further leakage or spillage if safe to do so. Local authorities should be advised if significant spillages cannot be contained.

Methods for containment and cleaning up: Methods for cleaning up: Avoid dust formation. 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.

Reference to other sections: Treat recovered material as described in the section "Disposal considerations".

Section 7: Handling and Storage

Precautions for safe handling: Advice on safe handling: Handle in an enclosed, controlled process, under dry protective gas such as argon when possible. Air- and moisture-sensitive. Use non-sparking tools. Protect from sources of ignition. Protect from water/moisture. Avoid contact with skin and eyes. Wash thoroughly before eating or smoking. See Section 8 for information on personal protection equipment. Hygiene measures: Do not eat, drink or smoke when using this product.

Conditions for safe storage, including incompatibilities: Requirements for storage areas and containers: Ytterbium metal should be stored in tightly-closed containers under argon or mineral oil. Store in a cool, dry area. Protect from water/moisture. See section 10 for more information on incompatible materials.

Section 8: Exposure Controls/Personal Protection

Control parameters: Occupational exposure limits: Contains no substances with occupational exposure limit values.

Exposure controls: Appropriate engineering controls: Handle in a humidity-controlled atmosphere. Handle in an enclosed, controlled process 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: Eye/face protection: Chemical safety goggles. Hand protection: Impermeable gloves. Body protection: Protective work clothing as necessary. Respiratory protection: If permissible levels are exceeded, use NIOSH-approved respirator.

Section 12: Ecological Information

Toxicity: Atmospheric Fate: Metal-containing inorganic substances generally have negligible vapour pressure and are not expected to partition to air. Environmental Fate: Environmental processes, such as oxidation, the presence of acids or bases and microbiological process, may transform insoluble materials to more soluble ionic forma. Environmental processes may enhance bioavailability and may also be important in changing solubilities. Aquatic/Terrestrial Fate: When released to dry soil, most metals will exhibit limited mobility and remain in the upper layer; some will leach locally into ground water and/or surface water ecosystems when soaked by rain or melt ice. A metal ion is considered infinitely persistent because it cannot degrade further. Persistence and degradability: No data available. Bioaccumulative potential: No data available. Mobility in soil: No data available. Results of PBT& vPvB assessment: Not relevant. Other adverse effects: Do not allow material to be released to the environment.

Section 13: Disposal Considerations

Waste treatment methods: Dispose of in accordance with local and national regulations. In some areas, certain wastes must be tracked.
