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
