To the best of our knowledge the chemical, physical and toxicological properties of terbium oxide have not been thoroughly investigated or recorded.
Terbium is considered a rare, earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of the rare earth elements include writing, ataxia, labored respiration, walking on toes with and sedation. The rare earth exhibit low toxicity by ingestion exposure. However, the intraperitoneal route is highly toxic while the subcutaneous route is poison to moderately toxic. The production of skin and lung granulomas after exposure to them requires extensive protection to prevent such exposure. (Sax, Properties of Materials, eighth edition.
Acute: 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 collages.
Chronic: Prolonged and repeated inhalation may cause writhing, loss of muscle coordination,
Ingestion: May cause nausea, vomiting, diarrhea, abdominal burning and cramp-like pain.
Skin: May cause redness, itching and burning.
Eye: May cause redness, itching, burning and watering.
Medial Conditions Generally Aggravated by Exposures: Pre-existing respiratory disorders.
Inhalation: Remove victim to fresh air, keep warm and quiet, and 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, brush material off skin, wash affected area with mild soap and water, and seek medical attention if symptoms persist
Eye: Flush eyes with lukewarm water, lifting upper and lower eyelids for at least 15 minutes
and seek medical attention if symptoms persist.
SECTIONVII-PRECAUTIONS FOR SAFEHANDLINGANDUSE Stepstobe takenincasematerialisreleasedorspilled:
Wear appropriate respiratory and protective equipment specified in section VIII-Control Measures. Isolate spill area, provide ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust.
Dispose of in accordance with state, local, and federal regulations.
Store in cool, dry area and in tightly sealed container. Wash thoroughly after handling. Keep
low levels. 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.
