CLASS OF CHEMICALS | RECOMMENDED STORAGE METHOD | EXAMPLES | INCOMPATIBILITIES SEE MSDS IN ALL CASES |
Oxidizers | Store inside a noncombustible cabinet, separate from flammable and combustible materials. Store inorganic oxidizers, organic peroxides, separate from each other via secondary containment. All oxidizers at GUMC should be considered shock-senstive. | Inorganic oxidizers - Sodium hypochlorite, ammonium nitrate Organic peroxides – methyl ethyl ketone peroxide, allyl compounds, haloalkenes, dienes, monomeric vinyl compounds, vinylacetylenes, unsaturated cyclic hydrocarbons | Separate from reducing agents, flammables and combustibles |
Flammable Liquids | Store in grounded flammable storage cabinet. | Acetone, benzene, diethyl ether, methanol, ethanol, toluene | Separate from acids, bases, oxidizers, and poisons. |
Flammable Solids | Store in grounded flammable storage cabinet. Flammable solids must be segregated from flammable liquids via secondary containment. | Phosphorus, lithium, sodium, potassium | Separate from acids and oxidizers. |
Corrosives Acids | Store in separate acid storage cabinet. Within the acid cabinet store each of the following groups separately via secondary containment: oxidizing acids, flammable (organic) acids, and mineral acids. | Oxidizing acids - nitric acid, perchloric acid, chromic acid, picric acid, chromerge Flammable and organic acids – glacial acetic acid, trifloroacetic acid, trichloroacetic acid, triflic acid Mineral acids - Hydrochloric acid, sulfuric acid, phosphoric acid | Separate from flammable liquids, flammable solids, bases, oxidizers. |

Corrosives - Bases | Store in separate storage cabinet. Store inorganic bases separate from reducing agents via secondary containment. | Inorganic bases –sodium hydroxide, potassium hydroxide, ammonium hydroxide Reducing agents – Lithium aluminum hydride, sodium borohydride, lithium borohydride | Separate from oxidizers and acids. |
Compressed Gases- Oxidizing | Store in a cool, dry area, away from flammable gases and liquids. Securely strap or chain cylinders to a wall or bench. | Oxygen, chlorine | Separate from flammable gases. |
Compressed Gases- Flammable | Store in a cool, dry area, away from oxidizing gases. Securely strap or chain cylinders to a wall or bench top. | Methane, acetylene, propane | Separate from oxidizing and toxic compressed gases, oxidizers. |
Compressed Gases- Poisonous | Store in a cool, dry area, away from flammable gases and liquids. Securely strap or chain cylinders to a wall or bench. | Carbon monoxide, hydrogen sulphide (H2S) | Flammable and/or oxidizing gases. |
Compressed Gases – Inert | Store in a cool, dry area. Securely strap or chain cylinders to a wall or bench. | Nitrogen, helium, argon | See MSDS |
General Chemicals Non-reactive | Store on general laboratory benches or shelving preferably behind glass doors, or below eye level. | Agar, sodium chloride, sodium bicarbonate, and most non-reactive salts | See MSDS |

Water Reactive Chemicals | Store in dry, cool, location, protect from water fire sprinkler. Note: Many water reactive chemicals are flammable solids. If flammable solid, store as such. If not, store separately from all other chemicals. | Sodium metal, potassium metal, lithium metal, lithium aluminum hydride | Separate from all aqueous solutions, and oxidizers. |
Poisons (Toxicological Hazard) | If poisons can be categorized as oxidizer, acid, or flammable, store as such. If non-reactive but highly toxic store separately from all other chemicals. | Cyanides, heavy metals compounds (e.g., cadmium, mercury, osmium) methyl iodide, dimethyl sulfate, mercury | Flammable liquids, acids, bases, and oxidizers. |
