Store peroxidizable chemicals away from source of heat, light, sparks, other ignition sources, and mechanical shock. Peroxide-forming compounds should be kept at a cool temperature. Do not refrigerate peroxides if solid peroxide may precipitate or freeze out. Solid material is especially sensitive to shock. Do not store peroxide-forming compounds in glass bottles having ground glass or screw caps, or metal cans with metal screw caps.
Serious explosions can occur by merely unscrewing the top of a glass bottle that contains peroxides.
Metal cans with plastic caps and polyethylene bottles are safer containers for ethers and other peroxidizable compounds. The safest container is the one supplied by the manufacturer. Test peroxidizable substances before using, and periodically in storage as specified in item 2 above. Chemistry stockroom keeps a supply of these on hand. Peroxides may be removed from solvents by passing the solvent through a column of alumina or Dowex-1 resin.
