Lab Waste, Mixed

  • Occasionally laboratory waste may contain or be contaminated with a combination or mixture of biological, chemical and radioactive materials. This type of waste poses a challenge for disposal. Inactivation and disposal will be considered on a case-by-case basis, as required. See the Environmental Health & Safety webpage for more information.
  • As a general rule for waste containing combinations of hazardous chemical, radioactive and biological agents, the biological hazard should be inactivated first.
  • Steam sterilization is generally not recommended for waste containing combinations of significant quantities of hazardous chemical, radioactive and biological agents. Chemical disinfection should be used.
