How should I properly store sodium metal?
Sodium metal is best stored in a glass container covered in dry mineral oil. The bottle should be labeled appropriately. The bottle should then be placed in a heavy-duty plastic bag and sealed with a twist-tie. Should the container be broken, the sodium metal will still be contained in the plastic bag. The container and bag should be placed into a metal paint can, surrounded by kitty litter and sealed. The outside of the metal can should also be labeled appropriately.
