This category includes almost all organic solvents. This is only a small number of examples. An aqueous solution that has a pH of less than or equal to 2, or greater than or equal to 12.5 is considered corrosive. Corrosive materials also include substances such as thionyl chloride, solid sodium hydroxide and some other non-aqueous acids or bases. Instructions for the disposal of concentrated solutions of acids and bases are given in Section E. Reactivity Chemicals that react violently with air or water are considered hazardous.
Examples are sodium metal, potassium metal, phosphorus, etc.
Instructions for the disposal of these reactive materials are given in section I. Solutions of certain cyanide or sulfides that could generate toxic gases are also classified as reactive. The impetus behind the new rule is to address the leaching of organic compounds as well as inorganic elements. The list of Toxic Characteristic wastes is below, with their individual regulatory levels. This section presents a list of substances which have been shown in scientific studies to have toxic, carcinogenic, mutagenic or teratogenic effects on humans or other life forms are designated either as Acutely Hazardous Waste or Toxic Waste by the Environmental Protection Agency. Laboratories wishing to dispose of materials containing dilute concentrations of these constituents should contact the Department of Environmental Health and Safety for advice regarding the proper disposition of the materials.
