Use sources such as SDSs at http://ehsa.gatech.edu/ehsa for guidance on storage, incompatibility, reactivity and stability for chemicals. If the link for EHSA does not work, be sure you are connected to the GT or GTRI VPN.

• Do not tip bottles when returning them to a shelf.  Shelves must have enough clearance to accommodate the largest container.
• Do not store chemicals (except cleaners) under sinks.  Use approved flammable storage lockers, corrosive storage lockers, shelves or cabinets.
• Avoid stockpiling chemicals. 
• Purchase only what is needed.  If possible borrow chemicals from a colleague or contact EHS for assistance at ehsa@gatech.edu to assist you in finding a source of the chemical at GT. 
• Conduct periodic cleanouts to prevent accumulating unnecessary chemicals.
• Do not sort and store chemicals alphabetically unless they have first been separated into hazard classes
• Ensure that caps and lids on all chemical containers are tightly closed to prevent evaporation of contents. A Teflon or PVC cap liner may be used to provide a better seal.  These are available through several commercial sources, including VWR Scientific. 
• Avoid exposure of chemicals to heat or direct sunlight. This may lead to the deterioration of storage containers and labels, as well as the degradation of the chemicals.  Some time-sensitive chemicals such as peroxide-formers (see below) can be affected as well.
• Store solids on shelves or in cabinets.
• Avoid storing chemicals on countertops or in fume hoods except for those being currently used.
