See other side for information about the Stanford Storage Group System. Storage Groups are continuously reviewed and updated as needed. If you have any questions or suggested changes, please contact the EH&S at 723-0448. Stanford University Compatible Storage Group Classification System Should be used in conjunction with specific storage conditions taken from the manufacturer’s label and MSDS. If space does not allow Storage Groups to be kept in separate STORAGESTORAGE GROUPSGROUPS cabinets the following scheme can be used with extra care taken to Store chemicals in separate secondary containment and cabinets provide stable, uncrowded, and carefully monitored conditions.
