Chemical Storage Guidelines

It is very important that all chemicals used at Walla Walla University be stored properly in order to reduce the risk of accidents.  Keep the following points in mind:

1. Proper containers

   • Be sure that all materials are stored in containers appropriate for the material.  For some chemicals, this may mean glass or plastic; others may require metal containers.  If you have any question, contact the Chemical Hygiene Officer.
      

2. Proper labeling

   • Containers must be well-labeled for easy identification, especially if more than one person has access to the storage area.  Almost all purchased materials will come with appropriate labeling.  If a chemical is transferred into a secondary container, that container must be labeled with the full name of the chemical or product (no abbreviations), the concentration (if appropriate), the date of transfer, and the name of the individual who performed the transfer.
      

3. Closed containers

   • Containers should always be kept closed with a tight sealing lid or cap unless material is being added to or removed from the container. 
      

4. Proper storage

   • Containers of incompatible chemicals, such as flammables and oxidizers, must be stored separately.  Mixing incompatible chemicals accidentally can cause dangerous results, such as toxic gasses, fire, or explosions.
