Uranium oxide: 99.9% NFPA Rating: Not known
Emergency overview: Special Hazard Precautions: In some states of this material, it can be extremely flammable, may be pyrophoric. It is radioactive. Acute: Kidney damage, arterial lesions and possible liver effects. May irritate eyes and skin. Toxic if inhaled. Irritating to lungs. May cause kidney damage. arterial lesions, and liver effects. Chronic: Dermatitis. Possible carcinogen of lymphatic and blood-forming tissue. Signal Word Harmful! Physical Health Hazards: Harmful by inhalation, in contact with the skin and if swallowed. Personal protection: Wear approved protective clothing when working with this material in order to avoid any contact with material at all. Long sleeves and/or lab coat are recommended to protect against skin contact. Approved chemical goggles are recommended to protect against eye contact. Respiratory Protection: NIOSH/MSHA Approved high efficiency particle respirator. Use rubber gloves for hand protection. Physical state: Solid chunks or fines associated with the chunks Color: Dark brown to black chips, with some associated "fines" Odor: None Odor threshold: No data available Potential Health Effects: Routes of exposure Inhalation of the fine powder, skin, eye Signs and Symptoms of Acute Exposure: Ingestion: May cause kidney damage and acute necrotic arterial lesions. May also effect liver function. Skin: May cause irritation Eye: May cause irritation Inhalation: Considered toxic by inhalation due to lung irritation from inhaled fine particles from the "dust" that is always present. May also cause kidney damage and acute necrotic arterial lesions. Liver effects might be present as well. Chronic Health Effects Summary: Skin: May cause dermatological problems. Conditions Aggravated by Exposure: None known. Signs and Symptoms of Overexposure: Precise health hazards are not known. But chronic radiation effects are similar to those of ionizing radiation. It is reported that carcinogenicity is related to dose and exposure time. Uranium may cause cancer of lymphatic and blood-forming tissues.
Take proper precautions to ensure your own health and safety before attempting to rescue and providing first aid. For specific information refer to the Emergency Overview in Section of this MSDS. Inhalation: No specific information is available, but one should contact medical help at once. Eye Contact: Wash eyes, including under lids, with copious amounts low-pressure water, for minimum of 15 minutes, removing contact lenses if possible. Then seek medical advice from a qualified physician. Skin Contact: Remove contaminated clothing, then rinse skin thorough with large amounts of soap and water to remove all traces of the substance. If irritation persists, contact qualified medical assistance. Ingestion: Adverse health effects due to ingestion are to be expected, but exactly what are these health effects are not known. Wash out mouth with water but never give liquids to an unconscious person. Call a physician at once and seek other medical attention.
NFPA Rating: Not known Flammability classification: Not known. Flash Point/Method: Not applicable Auto-Ignition Temperature: Not known Flammable Limits: Lower: Not applicable Upper: Not applicable Hazardous Combustion Products: Not known. Special Conditions to Avoid: None specifically known. Extinguishing Media: Fires: Material is flammable and may be pyrophoric. Do not use water, use dry chemical extinguishing agents. Fire Fighting Instructions: Protective Equipment/Clothing: Wear a NIOSH approved positive pressure self-contained breathing apparatus and firefighter turnout gear. Wear long sleeves and chemical goggles for eye protection. Instructions: Use flooding quantities of water until well after fire is out. If the product now wet with water starts to migrate to other areas or even to the outside environment, dike it at once to prevent that from happening. Keep moist to prevent a dust hazard from starting. Material could be spontaneously flammable in air, remove material form the area of the fire if without risk.
Release response: Wear NIOSH approved respirator, chemical safety goggles, rubber boots, and heavy rubber gloves. Sweep up wet product, place in a bag and hold for waste disposal. If product is tending to flow away from fire or spill area, try to dike the material to keep in one place. If a broom is used, remember that the broom, when dried out, will contain powder of the product and if the broom is put into continued use without proper cleaning, then a hazardous dust cloud could be created. Ventilate area and wash spill site after pick up is complete. Reportable Quantities: See Section 15: Regulatory information.
Handling: Use full protective gear as described above. Respiratory Protection: NIOSH/MSHA Approved high efficiency particle respirator. Storage: Keep container dry. Store away from excessive heat. Keep container closed to prevent contamination.
Engineering Controls: If user operations generate dust or fumes, ventilate area to prevent accumulation. Personal Protection: Inhalation: Use appropriate respiratory protection at all times. If product is to be used as part of a vacuum deposition process, we would recommend that all vacuum pumps be vented to the outdoors, in order to avoid any possible release of uranium compounds into the laboratory environment. Respiratory Protection: NIOSH/MSHA Approved high efficiency particle respirator. Skin: Protective clothing such as long sleeves or a lab coat should always be worn. Eye: Always use chemical goggles, even for work with small quantities, such as the loading of a tungsten basket or boat prior to making a deposition of the material. Chunks can be handled with a pair of fine tweezers, the best being a Style #5.
Boiling Point/Range: Not applicable pH: Not applicable Vapor Pressure: Not applicable Viscosity: Not applicable Specific Gravity (Water = 1): 10.95 Water solubility: Not soluble Octanol/Water Partition Coefficient in Kow: Specific value not known Melting/Freezing Point: > 2868°C (5194°F) [from literature] Evaporation Rate: Not applicable Vapor Density (Air=1): Not applicable
Chemical Stability: The product is stable except for its radioactive disintegration. Half life for uranium 238, by far the most common isotope, is over 1,000,000 years. Conditions to Avoid: Exposure to water Incompatibility with: Water Hazardous Products of Deposition: Not known Reactions with Air and Water: Does slowly react with moisture and in the highly dried state, is pyrophoric and would react in air. However as the product is shipped from SPI Supplies, material is not pyrophoric.
