Tufts University
OP-21: Hazardous Waste Management

Tufts University produces hazardous chemical waste as part of its academic and support programs. The primary source of hazardous chemical waste are the research and teaching science and engineering laboratories. It is part of higher education to assist students in learning to identify,handle and dispose of hazardous chemicals in a safe and environmentally responsible manner. Tufts is committed to the recommendation of the American Chemical Society "to buy less, use less" in the design of experiments involving hazardous chemicals. Tufts University recycles all batteries as part of its universal waste program. In support activities, water based coatings,sealants and cleaning products are selected preferentially over such products that contain organic solvents. There are strict limits on the disposal of chemicals into the sewer and into solid waste containers hence all chemical waste is analyzed and disposed of as either hazardous or non-hazardous, non-regulated waste. Additionally, the Department of Environmental Health and Safety considers the following chemicals Particularly Hazardous Substances and require that a written safety plan be prepared and followed when using these chemicals in vitro (in the laboratory) or in vivo (in animals). * Select Carcinogens * Reproductive Toxins * Highly acutely toxic chemicals or a hazardous drug * Novel compounds of unknown toxicity There are also certain chemicals that need a registration form. This process limits the unnecessary use of these chemicals. For a more complete description of the process, see http://publicsafety.tufts.edu/ehs/?pid=88.

Tufts EHS directly and indirectly provides training to all members of the Tufts community that purchase,store,handle or dispose of chemicals. Individuals are trained to recognize each form of chemical waste and to understand the method of storing such wastes in each area where such wastes are produced. Hazardous chemical wastes are stored in Satellite Accumulation Areas prior to collection for packaging and transportation to TSDF facilities approved by the US EPA or MA DEP. All chemicals are stored,handled, transported and disposed of by persons and organizations approved because of their commitment to comply with all applicable regulations that prevent adverse human and environmental effects. As mandated by Tufts Environmental Health and Safety, hazardous chemical waste should be placed in a satellite accumulation area (SAA). Each point of generation (i.e. laboratory, clinic, maintenance area, etc.) should have an SAA that is under the direct supervision of trained employees. SAAs at a minimum should include a secondary containment system/bin, sign designating the area as a SAA, and a weekly log book. A dated container requiring pick up must be transported to a main accumulation area (MAA) within 3 days of full date noted on the waste label. Initial and annual refresher training is required for individuals who generate or participate in hazardous waste management activities.
