Hazards and Protection.
Storage
Protect from physical damage. Store at in cool, dry place. Protect personnel from radiation emanation if present. Separate from other readily oxidizable or combustible materials.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Do not touch damaged packages or spilled material. Cover liquid spill with sand, earth or other noncombustible absorbent material. Cover powder spill with plastic sheet or tarp to minimize spreading. Contact radiation safety officer.
Stability
No data.
Incompatibilities
Reacts rapidly with liquid bromine trifluoride.

Fire.
Fire fighting
Presence of radioactive material will not influence the fire control processes and should not influence selection of techniques. Small Fires: Dry chemical, carbon dioxide, water spray or regular foam. Large Fires: Water spray, fog (flooding amounts).
Fire potential
May burn but does not ignite readily.
Hazards
Decomposes to form U 2 O 7 then to UO 3 and oxygen.

Health.
Exposure limit(s)
OSHA: PEL (8 h TWA): 0.05 mg
Exposure effects
   Ingestion
See Inhalation.
   Inhalation
Stridor, dyspnea, upper airway injury, and pulmonary edema, especially following inhalation of vaporized caustics, may occur.
   Skin
Severe skin irritation and/or burns may occur.
   Eyes
See Skin.

First aid
 
   Ingestion
Medical problems take priority over radiological concerns. Use first aid treatment according to the nature of the injury. Do not delay care and transport of a seriously injured person.
   Inhalation
Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. See Ingestion.
   Skin
Immediately flush with running water for at least 20 minutes. See Ingestion.
   Eyes
Immediately flush with running water for at least 20 minutes. See Ingestion.
