First aid
General first aid measures. Get medical advice if you feel unwell
Handling, storage and disposal
Summaries only, follow the supplier SDS for your grade
Safe handling
Skin: Wear appropriate personal protective clothing to prevent skin contact.
Eyes: Wear appropriate eye protection to prevent eye contact.
Wash skin: When contaminated/Daily
Remove: When wet or contaminated
Change: Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises.
Provide: Eyewash fountains should be provided in areas where there is any possibility that workers could be exposed to the substances, this is irrespective of the recommendation involving the wearing of eye protection.
Storage
Finely divided uranium metal is highly reactive or pyrophoric, capable of igniting spontaneously. This type of material should be handled and stored in a manner that minimizes fire potential. Typically, machining chips are stored under water or machining oil in open storage containers so that any H2 generated does not accumulate.
Disposal
Disposal of... wastes /containing uranium/ should follow guidelines set forth by the Nuclear Regulatory Commission.

Uranium is a common naturally occurring and radioactive substance. It is a normal part of rocks, soil, air, and water, and it occurs in nature in the form of minerals "" but never as a metal. Uranium metal is silver-colored with a gray surface and is nearly as strong as steel. Natural uranium is a mixture of three types or isotopes called U-234/234U, U-235/235U and U-238/238U. All three are the same chemical, but they have different radioactive properties.Typical concentrations in soil are a few parts per million ppm. Some rocks contain high enough mineral concentrations of uranium to be mined.
