Uranium sulfate U(SO4)2 is a water soluble salt of uranium. It is a very toxic compound and should not be ingested. Uranium sulfate minerals commonly are widespread around uranium bearing mine sites, where they usually form during the evaporation of acid sulfate-rich mine tailings which have been leached by oxygen-bearing waters. Uranium sulfate is a transitional compound in the production of Uranium hexafluoride. It was also used to fuel aqueous Homogeneous Reactors.

| Hazards and Protection. | |
| Storage | Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. |
| 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. |
| 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). |

| Ingestion | See Inhalation. |
| Inhalation | Minimal risk if packaging remains intact. Package damage can result in a measurable release of radiation but the risk is still low. |
| Skin | See Inhalation. |
| Eyes | See Inhalation. |
First aid IngestionMedical 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. InhalationApply artificial respiration if victim is not breathing. Administer
oxygen if breathing is difficult. See Ingestion. SkinImmediately flush with running water for at least 20 minutes. See
Ingestion. EyesImmediately flush with running water for at least 20 minutes. See
