Only small volume containers of non-hazardous chemicals should be stored on elevated shelves. These include dry powders as well as
aqueous solutions of buffers, salts, and other dilute materials.
Stock containers of flammable and corrosive chemicals should always be separated from each other and stored at or below eye level.
Use a flammable storable cabinet for flammable liquids and keep corrosive chemicals in secondary containers (e.g., plastic tray).
