Compatibility of Chemicals

The following outline can be used to segregate laboratory chemicals. Chemical groups should be kept separate from each other.

Group	Examples	Hazard Class	Note
A: Inorganic Acids and Related Compounds	Hydrochloric Acid, Sulfuric Acid, Nitric Acid (<40%), etc.	Corrosive	N/A
B: Alkalis, Bases, Amines	Caustic Soda, Potassium Hydroxide, Sodium Hydorxide, Ethanolamine, etc.	Corrosive	N/A
C: Elements and Inorganic Salts, Carcinogens, Pesticides	Mercury, Lead, Aluminum Sulfate, Sodium Thiosulfate, Benzidine, Aldrin, Chlordane, etc.	Poison	N/A
D: Organic Solvents, Aldehydes, Esters, Ketones, Hydrocarbons	Methanol, Acetaldehyde, Ethyl Ether, Acetone, Hexane, etc.	Flammble or Combustible Liquids	N/A
E: Reactive Materials	Aluminum Hydride, Sodium Metal, Phosphorous Pentoxide, Potassium Metal, etc.	Flammable Solid, Corrosive	N/A
F: Organic Acids, Substituted Acids	Acetic Acid, Butyric Acid, Formic Acid, etc.	Corrosive	N/A
G: Oxidizers	Ammonium Nitrate, Potassium Permanganate, Sodium Nitrite, Barium Chlorate, etc.	Oxidizer	N/A
H: Peroxides	Benzoyl Peroxide, Urea Peroxide, Peracetic Acid, Cummene Hyperoxide, etc.	Peroxide	N/A
I: Cyanide, Sulfides	Potassium Cyanide, Potassium Sulfide, Hydrocyanic Acid, Allyl Cyanide, etc.	Poison	Note: Keep Away from Acids
