Administrative data
First-aid measures
First Aid: Eyes
Flush immediately with water for at least 15 minutes. Do not rub eyes. If irritation persists get medical attention.
First Aid: Skin
For skin contact, wash immediately with soap and water. If irritation persists, get medical attention.
First Aid: Ingestion
If the material is swallowed, get immediate medical attention or advice -- Do not induce vomiting.
First Aid: Inhalation
Remove affected person immediately to fresh air. If respiratory irritation occurs, if breathing becomes difficult, or if other symptoms develop, seek medical attention immediately.
First Aid: Notes to Physician
While unlikely to occur due to insoluble nature of material, the symptoms of acute rare earth toxicity include spontaneous defecation, writhing, ataxia, labored respiration, sedation, hypotension, and cardiovascular failure.
Fire-fighting measures
General Fire Hazards
This material will not burn.
Hazardous Combustion Products
None expected.
Extinguishing Media
Use methods for the surrounding fire.
Fire Fighting Equipment/Instructions
Wear full protective clothing, including helmet, self-contained positive pressure or pressure demand breathing apparatus, protective clothing and face mask.
Accidental release measures
Containment Procedures
Minimize generation of dusts.
Clean-Up Procedures
Treat as nuisance dust. Wear respiratory protection during cleanup. Sweep up or vacuum material and place in appropriate container for disposal. Rinse spill area with water.
Evacuation Procedures
Ordinarily not necessary. If large quantity of dust is released, isolate area and keep unnecessary personnel away.
Special Procedures
Avoid inhalation of dust from the spilled material. Follow all Local, State, Federal and Provincial regulations for disposal.
Handling and storage
Handling Procedures
Follow good industrial hygiene practices when handling this material. Keep formation of airborne dusts to a minimum.
Storage Procedures
Store in a cool, dry area away from moisture and excessive heat.

Exposure controls / personal protection
A: General Product Information
Keep formation of airborne dusts to a minimum.
B: Component Exposure Limits
Lutetium oxide (12032-20-1)
ACGIH: 10 mg/m3 TWA (inhalable fraction, particulate matter containing no asbestos and <1% crystalline silica); 3 mg/m3 TWA (respirable fraction, particulate matter containing no asbestos and <1% crystalline silica) (related to Particulates not otherwise specified (PNOS))
OSHA: 15 mg/m3 TWA (total dust); 5 mg/m3 TWA (respirable fraction) (related to Particulates not otherwise regulated)
Silicon dioxide, amorphous (7631-86-9)
NIOSH: 6 mg/m3 TWA
Engineering Controls
Ensure adequate ventilation to remove and prevent buildup of dust generated during handling or processing.
PERSONAL PROTECTIVE EQUIPMENT
Personal Protective Equipment: Eyes/Face
Wear safety glasses.
Personal Protective Equipment: Skin
Normal work clothing (long sleeved shirts and long pants) is recommended. Use impervious gloves. Wash hands thoroughly after handling.
Personal Protective Equipment: Respiratory
Treat as nuisance dust. Wear NIOSH/MSHA approved respirator when workplace conditions warrant use.
Personal Protective Equipment: General
Use good industrial hygiene practices in handling this material.
Stability and reactivity
Chemical Stability
Stable under normal conditions.
Chemical Stability: Conditions to Avoid
Avoid dispersion of dust in air.
Incompatibility
Very slightly soluble, even in strong acids.

Disposal considerations
Waste treatment methods
Recommendation:
Dumping into the environment must be prevented.
Waste disposal according to official state regulations.
Recovery or recycling, when possible.
