Storage Groups
Segregate toxic substances according to Stanford's Compatible Storage
Group classification system:
- A: Compatible Organic Bases, Flammables, and Poisons
- B: Compatible Pyrophoric and Water Reactive Materials
- C: Compatible Inorganic Bases, Oxidizers, and Poisons
- D: Compatible Organic Acids, Flammables, and Poisons
- E: Compatible Oxidizers, Organic Peroxides and Acids
- F: Compatible Inorganic Acids not including Oxidizing or Organic Acids
- G: Non Reactive Materials
- H: Flammable and Pyrophoric Compressed Gases
- I: Compatible Corrosive and Oxidizing Gases and Inert Gases
- J: Poison Compressed Gases, not Flammable or Reactive
- K: Compatible Explosive or other highly Unstable Material
- L: Non-Reactive Flammable and Combustible, including solvents
- X: Incompatible with all other storage groups
- U: Storage Group unknown, no data available
Note: These storage groups are used for solids, liquids, and gases.
Stock rooms should be well marked and ventilated by their own local exhaust systems.
Questions? Call EH & S Hazardous Materials at 725-1472.
These Storage Groups (except for X and K) can be stored on the same shelf
or within the same cabinet if each Group is segregated by secondary
containment:
A, B, D, G, L
C, E, F, G
K, X = Store Separately
