Laboratory Safety Manual

42 Laboratory Safety Manual Environmental Health and Safety Equipment Disposal Unwanted laboratory equipment includes working and non-working appliances, centrifuges, lasers, ovens, and other items used for research. At a minimum, researchers generating unwanted equipment must ensure that: • All hazardous substances have been removed and the equipment has been decontaminated. Biosafety cabinets must be decontaminated by a certified NSF technician before disposal. Fume hoods must be tested by EH&S for contamination before removal. • A completed Laboratory Equipment Disposal Form has been forwarded to EH&S. • EH&S has inspected the equipment and authorized transfer and/or disposal through Iowa State University (ISU) Surplus. • All radioactive waste materials, x-ray, and radiation producing devices will be managed by EH&S. Radiological Waste Materials Researchers generating radioactive waste materials must separate materials by radionuclide half-life into the following categories and sub-categories (collection containers): • Solids – into combustible, non-combustible, sharps (needles and razor blades), and source container (lead containers and source vials) groups • Liquids – into aqueous, organic, and flammable groups • Radioactive tissue (carcasses, viscera, and blood) Accumulated materials must be properly packaged, labeled, and placed in a designated waste collection area. Container labels are supplied by EH&S. Request collection of radioactive waste materials by submitting an online request. Refer to the Radioactive Materials Safety Manual for more information.
