Emory University - Department of Chemistry Chemical Waste Disposal Guidelines Important Notices (1) The information provided in this document pertains solely to procedures of chemical waste collection and disposal within the Department of Chemistry at Emory University. It is a supplement to the Chemical Safety Manual and Chemical Hygiene Plan maintained by the Environmental Health and Safety Office (EHSO) of the University. All users of this supplement must be familiar with both documents, available at . Download these documents by selecting the “Chemical Safety” link of the above URL. (2) Procedures presented here and those found in reference materials are intended to be carried out only by, or under the direct supervision of, trained scientists or technologists who understand the chemistry and hazards involved. Appropriate personal protection should be used . Introduction All work in a chemistry laboratory eventually generates chemical waste. The individual laboratory worker carries the legal and ethical responsibility to learn and follow proper procedures for safe disposal of all waste material generated in the course of his or her work. Effective immediately, the disposal of pyrophoric, air- or moisture-sensitive, highly reactive substances, and gas cylinders (both high-pressure, and low-pressure) through the waste facility (Emerson E133) is no longer acceptable. This document provides guidelines for the proper inactivation of these chemicals prior to disposal through the waste facility. Additional information on the disposal of other classes of hazardous chemical waste can be found in the Chemical Safety Manual (EHSO). Exceptions to this policy can be granted through the Chemical Safety Office of the University for chemicals in unstable condition (i.e. picric acid, peroxide forming materials), and leaking or damaged containers. Contact the Chemistry Safety Committee (Stefan Lutz, Emerson Hall E205) for details. Please remember that the improper disposal of chemical waste (i.e. simply depositing the waste or unknown chemical in Emerson E133) will require removal by external professionals and the substantial extra costs will be fully charged to your advisor’s account .

General Waste Disposal Procedures (reprinted from the Chemical Safety Manual of Emory University) a) Segregation of Chemicals Chemical wastes from each specific process should be stored separately. Solvent wastes are the only wastes that may be stored together in the same container, however halogenated and non- halogenated should be segregated. Other wastes may be able to be combined to save storage space, but approval must be received from the Chemical Safety Office before doing so. At a minimum, the following wastes should be stored separately: Acids, Bases, Amines, Cyanides, Halogenated Solvents, Metals, Non- halogenated Solvents, Oxidizers, Sulfides, Water Reactive and Extremely Toxic compounds. b) Containers and Packaging
