Each material must be individually evaluated to determine
where and how it should be stored. The information contained
in the MSDS regarding reactivity, compatibility and storage
requirements shall be applied. As a general rule, flammable
or combustible liquids, toxic chemicals, explosives, oxidizing
agents, corrosives, water-sensitive chemicals and compressed
gases should be segregated. The following table lists
some common chemicals and what they are incompatible with.
