- The exact chemical contents preceded by the word "Waste" (e.g. Waste Ethanol, Waste Hydrochloric Acid, etc.) Generic identifications such as "Waste Solvents", Waste Pesticides, etc. are unacceptable. If wastes are in solution, the solvent must be identified even if the solvent is water. Labels must not contain abbreviations, chemical formulas or trade names.
- The estimated chemical concentrations (% by weight) of the wastes in the container. Concentrations must total 100%.The name of the Principal Investigator.
- Room Number and Building the waste is being removed from.
- A phone number for a contact person.
- If the waste is packaged in its original container without any other wastes and the exact chemical contents are listed on the label under "Ingredients", the only additional labeling normally required will be the words "Hazardous Waste", the building and room number where the waste is to be picked up and date determined to be a waste.
