How to Use
Storage groups are groups of chemicals that will not react violently if mixed together. Stanford’s Storage Group System applies to laboratory scale storage, not non-laboratory storage. Other classification systems define groups by hazard classification. This system defines storage groups independent of main hazard classes, which allows for fewer groups. It is possible that chemicals listed in different storage groups are compatible because the groupings, by nature, are generalizations. With specific knowledge or information, chemicals from different storage groups could be stored together.
The various storage classifications are summarized in this PDF. To find the appropriate storage group for a given chemical, check your lab’s online chemical inventory or search using Stanford’s Chemical Safety Database.
