Dry Sand—
A Chemist’s Good Friend
Dry sand is a good fire extinguisher, especially for use with flam- mable metals like sodium. Dry, clean sand also can be used to dike and absorb a hazardous material spill. Sand provides necessary traction in a treacherous floor situation. See to it that dry, clean sand is available in your laboratory and chemical storeroom.
