Chemical Name: Dysprosium Nitrate
CAS Number: 10031-49-9
Concentration: Typically 98-100% pure
Impurities: May contain rare earth metal traces (less than 2%)
Inhalation: Move the person into fresh air. If breathing becomes difficult or labored, seek medical help straight away. Use artificial respiration if not breathing.
Skin Contact: Take off all contaminated clothing immediately. Rinse skin under running water for at least 15 minutes. Get medical advice if irritation remains.
Eye Contact: Rinse with water gently for at least 15 minutes. Hold eyelids open during rinsing. Ask for medical attention at once.
Ingestion: Rinse mouth thoroughly. Do not induce vomiting. Seek medical help without delay.
Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or foam.
Fire Hazards: May release toxic fumes such as nitrogen oxides and dysprosium oxides. Acts as a strong oxidizer, can increase the intensity of fire.
Protective Equipment: Firefighters must use self-contained breathing apparatus and full protective suit.
Specific Procedures: Remove material from fire area if safe. Cool containers with water spray to prevent pressure build-up and explosion.
Personal Precautions: Avoid exposure to dust. Wear protective gloves, chemical-resistant clothing, and goggles. Ensure adequate ventilation.
Environmental Precautions: Prevent material from entering drains, water bodies, and sewers. Contain spilled material with inert absorbent.
Clean-up Methods: Use non-sparking tools. Sweep up and collect into suitable containers for disposal. Wash spill site thoroughly with plenty of soap and water.
Handling: Always wear safety goggles, gloves, and protective clothing. Avoid contact with skin and eyes. Do not eat, drink, or smoke while handling.
Storage: Store in tightly sealed containers, kept in cool, dry, well-ventilated places. Keep away from acids, combustibles, and reducing agents. Store apart from food and beverages.
Incompatible Materials: Avoid storing with organic materials and strong reducing substances.
Engineering Controls: Local exhaust ventilation or process enclosure to minimize airborne exposure.
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, lab coat, and dust mask or respirator as required.
Hygiene Measures: Wash thoroughly after handling. Remove contaminated clothing. Clean protective gear before re-use.
Exposure Limits: No specific occupational exposure limits set for dysprosium nitrate. Use workplace controls to keep exposure as low as possible.
