Emergency overview: Oxidizing. Highly Toxic (USA); Very Toxic (EU). Appearance: Pale yellow crystalline solid Flash Point: n/a Warning! Fire hazard in contact with combustible materials. Target Organs: Kidneys, Liver Potential Health Effects Eye: Risk of serious damage to eyes. Skin: Irritating to the skin. Ingestion: Very toxic if swallowed. Inhalation: Irritating to the respiratory system. Toxic by inhalation. Chronic: Danger of cumulative effects. Additional toxicological information is available in Section 11.
Eyes: In case of eye contact, immediately flush with copious amounts of water for at least 15 minutes, holding the eyelids open. Seek immediate medical attention. Skin: In case of skin contact, wash with soap and flush with copious amounts of water for at least 15 minutes. Remove contaminated clothing and shoes. If irritation develops or persists, seek medical attention. Ingestion: If swallowed, and the victim is conscious, wash out mouth with water. Seek immediate medical attention. Inhalation: If inhaled, remove to fresh air. If breathing is difficult, seek immediate medical attention.
General Information: Wear self-contained breathing apparatus and protective clothing to prevent skin and eye contact. Emits toxic fumes under fire conditions. Contact with combustible material may cause fire. May react explosively with cellulose and certain organic solvents. Extinguishing Media: Water spray, carbon dioxide, dry chemical powder or appropriate foam.
General Information: Evacuate area. Handle as a radioactive spill. Spills/Leaks: Wear self-contained breathing apparatus, rubber boots and heavy rubber gloves. Sweep up, place in a bag, and hold for waste disposal. Avoid raising dust. After material pickup is completed, ventilate area and wash the spill site.
Handling: Do not breathe dust. Avoid all contact with eyes, skin or clothing. Avoid repeated or prolonged exposure. Storage: Store in cool, dry area in tightly closed containers. Store away from combustible materials, reducing agents, cellulose, or organic solvents.
Engineering Controls: Safety shower and eye wash station must be available to the work area. Use only in a chemical fume hood. Exposure Limits: USA MSHA Standard-air TWA = 0.2 mg(U)/m3 USA OSHA PEL 8hr TWA = 0.05 mg(U)/m3 Personal Protective Equipment Eyes: Chemical splash goggles Skin: Chemical-resistant gloves, other protective clothing such as long sleeves or a lab coat should be worn to prevent skin contact. Respirators: Use a NIOSH/MSHA or European Standard EN 149 approved respirator. If risk assessment indicates use of air-purifying respirators are needed, use a full-face respirator with type N100 (US) or type P3 (EN143) respirator cartridges as backup to engineering controls. General Hygiene Measures: Wash thoroughly after handling.
Physical State: Solid Appearance: pale yellow crystalline Odor: odorless pH: N/A Vapor Pressure: N/A Vapor Density: N/A Evaporation Rate: N/A Viscosity: N/A Boiling Point: N/A Freezing/Melting Point: N/A Autoignition Temperature: N/A Flash Point: N/A Decomposition Temperature: N/A Explosion Limits Lower: N/A Upper: N/A Solubility in water: Insoluble Specific Gravity/Density: N/A Molecular Formula: N2O8U·6H2O Molecular Weight: 502.1 N/A = Not available
Chemical Stability: Stable Conditions to Avoid: Moisture Incompatibility with Other Materials: Avoid contact with combustible materials, cellulose, reducing agents, organic solvents Hazardous Decomposition of Products: Oxides of uranium, Nitrogen oxides Hazardous Polymerization: Will not occur.
