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.
- Steam sterilization is generally not recommended for waste containing combinations of significant quantities of hazardous chemical, radioactive and biological agents.
- Refer to disinfection procedures in Section 5.1. After disinfection, the remaining waste can be disposed of as chemical or radioactive waste.
- Waste containing or contaminated with chemical and radioactive materials, will be treated as radioactive waste. Refer to Section 5.3.
