Segregation and Storage of Chemicals According to Hazard Class

There are a number of different strategies for storing solid and liquid chemicals ranging from extremely complicated (over 24 compatibility groups) to extremely simple (alphabetical- easy, but unwise).  GT EHS requires that chemicals be stored by simple compatibility group:

  • Acids
  • Bases
  • Flammables
  • Oxidizers
  • Water Reactives
  • Air Reactives (Pyrophorics)
  • Extremely Toxic. 

Chemical storage guidelines are presented below.  Use these to segregate and store chemicals according to their hazard class. This prevents an undesirable chemical reaction from occurring should two or more chemicals accidently mix.  Consult sources such as the substance’s Material Safety Data Sheet for specific storage guidelines.
