| General Instructions |
- Avoid generating mixed or multi-hazard waste. Prior to generating multi-hazard or mixed waste, contact the Environmental Compliance Manager ((301) 405-3163) for minimization techniques. If generation of mixed waste is unavoidable:
- Keep volume to a minimum
- Keep aqueous and organic waste separate
- Do not combine reactive chemicals such as strong oxidizers with organic compounds
- Keep solid and liquid wastes separate
- Keep short half-life (
<30 days) isotopes separate from longer half-life isotopes
- Identify all constituents - see Chemical Waste, Radioactive Waste and Biological Waste sections for required tags and markings
|
| Waste containing an Infectious agent and radioactive material |
- Do NOT autoclave.
- Seek advice from the Biological Safety Officer, as needed, before implementing inactivation procedures.
- Inactivate the infectious waste and dispose of the waste as Radioactive Waste according to the Radioactive Waste section.
- Follow the general instructions in the Radioactive Waste section for removal of the container.
|
| Waste containing an Infectious agent and a Hazardous chemical |
- Do NOT autoclave.
- Do NOT combine incompatible chemicals such as strong oxidizers with organic compounds.
- Seek advice from the Biological Safety Officer, as needed, before implementing inactivation procedures.
- Inactivate the infectious agent and dispose of the waste as Chemical Waste according to the Chemical Waste section.
- Follow the general instructions in the Chemical Waste section for removal of the container.

| Waste containing an Infectious agent, Radioactive material, and a Hazardous chemical |
- Do NOT autoclave.
- Do NOT combine incompatible chemicals such as strong oxidizers with organic compounds.
- Seek advice from the Biological Safety Officer, as needed, before implementing the inactivation procedures.
- Inactivate the infectious agent.
- Affix a "UM Hazardous Waste" tag and a "Caution - Radioactive Material" tag to the waste container. Consult the Chemical and Radioactive Waste sections for packaging guidelines.
- Dispose of the waste container according to the Radioactive Waste section.
|
| Mixture of Chemical and Radioactive wastes |
- Do NOT combine incompatible chemicals such as strong oxidizers with organic compounds.
- Affix a Hazardous Waste Label and a "Caution - Radioactive Material" label / tag to the waste container. Consult the Chemical and Radioactive Waste sections for packaging guidelines.
- Dispose of the waste container according to the Radioactive Waste disposal guidelines.
