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