Safety Information
Behavior in Fire: Decomposes to form U 2 O 7 then to UO 3 and oxygen.
Excerpt from ERG Guide 161 [Radioactive Materials (Low Level Radiation)]: Presence of radioactive material will not influence the fire control processes and should not influence selection of techniques. Move containers from fire area if you can do it without risk. Do not move damaged packages; move undamaged packages out of fire zone. SMALL FIRE: Dry chemical, CO2, water spray or regular foam. LARGE FIRE: Water spray, fog (flooding amounts). (ERG, 2016)
Excerpt from ERG Guide 161 [Radioactive Materials (Low Level Radiation)]: As an immediate precautionary measure, isolate spill or leak area for at least 25 meters (75 feet) in all directions. LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet). FIRE: When a large quantity of this material is involved in a major fire, consider an initial evacuation distance of 300 meters (1000 feet) in all directions. (ERG, 2016)
Excerpt from ERG Guide 161 [Radioactive Materials (Low Level Radiation)]: Do not touch damaged packages or spilled material. Cover liquid spill with sand, earth or other non-combustible absorbent material. Cover powder spill with plastic sheet or tarp to minimize spreading. (ERG, 2016)
Approved respirator, leather, gloves and protective goggles. (USCG, 1999)
Drug Information
INHALATION: Radiation injuries. EYES: Mild irritation. INGESTION: Injury to capillaries, tubular and glomerular nephritis, hepatitis, glycosuria and acidosis.
Call a physician. INHALATION: Remove from exposure and place on bed rest. EYES: Wash for 15 minutes with running water. Call a physician. SKIN: Wash with soap and water. INGESTION: Excretion is speeded by sodium bicarbonate (10 g in water every hour). Sodium citrate may offer protection to kidneys. (USCG, 1999)
uranium oxide (UO4)
uranium dioxideperoxide Use and Manufacturing
A boiling 10% solution of uranyl nitrate is treated dropwise with 30% H2O2. The resulting amorphous, white precipitate is filtered on the finest filter possible (membrane or Millipore filter) and washed thoroughly with boiling water. The peroxide, a bright sulfur-yellow after filtration, is first dried in the air on a clay plate, then at 100°C to constant weight, and stored in a vacuum over P2O5.Reaction of (NH4)2[UO2(C2O4)2] 3 H2O with H2O2 yields crystalline, nonhygroscopic UO4 2 H2O, which is converted to the dihydrate by storing in vacuum over P2O5.
