Guidelines for Safe Chemical Storage
Security
  • Limit access to chemical storage areas to authorized personnel only.
  • Keep chemical storage cabinets closed and locked when not in use.


Chemical storage areas
  • Provide adequate ventilation (about 6 room air changes per hour).
  • Install fire detectors.
  • Make sure shelves are strong and secure. Inspect them annually and replace and repair as needed.
  • Store containers no more than 2 deep with large containers in back. Maintain enough space between containers so that you can remove one without knocking others over.
  • Store large and heavy containers on lower
  • shelves.
  • Store hazardous materials below eye level.


Inventory management
  • Sort and store chemicals according to the following color code. Make sure that each container's label is marked with the appropriate color.
    • Blue (toxic chemicals)
    • Green (general chemical storage)
    • Red (flammable chemicals). Store only in cabinets approved for flammable materials.
    • White (corrosives). Separate acids and bases. Separate oxidizer acids (nitric and perchloric) from organic acids (formic, acetic, etc.).
    • Yellow (reactives)
  • Record the following data on the label of a newly received chemical: (1) the full level, (2) the date received, and (3) the person responsible for the chemical. Record the date on the label every time you open a container. Seal container caps with vinyl electrician's tape to avoid evaporation and leaks.
  • Examine chemical containers annually. Secure loose labels with clear packing tape and dispose of containers whose contents cannot be identified.
  • Maintain an inventory that is updated at least annually.
  • Purchase only what you can use in 2 years.
