How should I store reactive metals like sodium, potassium, lithium, etc?

Reactive metals should be stored in dry mineral oil in an unbreakable bottle. The mouth of the bottle should be wide enough so you can easily obtain the sample. The bottle should be placed in a plastic bag and sealed with a twist tie. The bag and bottle should be placed into a metal paint can and surrounded by cat litter. The metal lid should be firmly secured. Both the outside of the can and the individual bottle should be labeled with the chemical's name, concentration, how it can hurt you, and the date prepared.

Always buy reactive metals in as small a quantity as you can. The less you store, the less your hazard. All Flinn Scientific reactive metals are already packaged using the method described above.
