Chemical Storage Guidelines
Chemical Storage Guidelines
Safe chemical handling requires routine inspections of chemical storage areas and maintenance of stringent
inventory control. The inherent hazards of chemicals can be reduced by minimizing the quantity of chemicals
on hand. However, when chemicals must be used, proper storage and handling can reduce or eliminate
associated risks. All chemical storage areas and cabinets should be inspected at least annually and any
unwanted or expired chemicals should be removed.
Typical storage considerations may include temperature, ignition control, ventilation, segregation and
identification. Proper segregation is necessary to prevent incompatible materials from inadvertently coming
into contact. A physical barrier and/or distance is effective for proper segregation.
Proper storage information can usually be obtained from the Material Safety Data Sheet (MSDS), label, or
other chemical reference material. As required by 29 CFR 1910.1200, an MSDS must be on hand for every
hazardous chemical in your workplace. MSDSs must be provided by the manufacturer or distributor of
chemicals purchased. MSDSs are also available through the LINDEN system, CDC's Chemical Tracking
System. This system tracks CDC's chemical inventory and includes MSDSs for most chemicals in the
inventory. The Internet can also be used to find MSDSs. For a fast search for an MSDS on the Internet, go to
the CDC Intranet, select "Databases", then select "Scientific Information", and then "Material Safety
Datasheets". This site provides specific manufacturer information as well as generic information.
Considerations for proper storage:
● Ensure all containers of hazardous chemicals are properly labeled with the identity of the hazardous
chemical(s) and appropriate hazard warnings.
● Segregate all incompatible chemicals for proper storage of chemicals by hazard class. In other words,
store like chemicals together and away from other groups of chemicals that might cause reactions if
