Hazardous Chemical Disposal Section 15-Environmental Management is part of the Environmental Health & Safety Procedure Manual (PDF) as well as the Environmental Management Plan (PDF). Waste Identification • Hazardous Waste regulations require that hazardous waste be accurately identified. Common wastes include: • Spent solvents, acids, bases and oxidizers used in extractions, cleaning or other processes; • Unused reagents and other chemicals that are no longer needed, do not meet specifications, are contaminated, have exceeded their storage life or are otherwise unusable in the lab; • Waste oils; and • Other miscellaneous materials, including broken thermometers, heavy metal salts, pesticides, paints, etc. If you are unsure of how a chemical waste in your department should be disposed, contact the Mgr. EH&S (Sara Gibson x6923). Chemical waste pick ups are coordinated by the Mgr. EHS at the end of each semester.
